[0003] Currently, directional visual effects in game products are typically implemented using 2D texture effects. Specifically, 2D planar textures are used, and effects renderer scripts are used to achieve 2D dynamic effects such as movement, dissolution, showing, and hiding. However, when implementing directional visual effects based on 2D texture effects, multiple 2D timing maps need to be pre-designed and set for dynamic effects, and complex image processing is required on these timing maps, which is not conducive to improving the generation efficiency of directional marker effects. Summary of the Invention

It can generate a directional curve based on the position information of the emitting object and the target object of the effect, as well as the first curve generation parameters corresponding to the directional sign effect to be generated. Then, the directional curve is rendered in combination with rendering parameters to obtain the directional sign effect. There is no need to set and process a two-dimensional timing diagram, which helps to improve the generation efficiency of directional sign effects.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. At the same time, in the description of the embodiments of this application, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] This application provides a method, apparatus, electronic device, and computer-readable storage medium for generating pointing marker effects.

[0032] Specifically, this embodiment will be described from the perspective of a directional sign effect generation device, which can be integrated into an electronic device. That is, the directional sign effect generation method of this application embodiment can be executed by an electronic device. Optionally, the electronic device may include a terminal device. The terminal device may be a mobile phone, tablet computer, smart Bluetooth device, laptop computer, game console, or personal computer (PC), etc.

[0033] The directional sign effect generation method provided in this application can be applied to a directional sign effect generation system. This system can include a terminal device and a server. The terminal can be a device including receiving and transmitting hardware, i.e., a device with receiving and transmitting hardware capable of performing bidirectional communication over a bidirectional communication link. The terminal device and the server can communicate bidirectionally via a network.

[0034] Optionally, the electronic device can be a server, which can be a standalone server, a server network, or a server cluster, including but not limited to computers, network hosts, single network servers, multiple network server sets, or cloud servers composed of multiple servers. A cloud server consists of a large number of computers or network servers based on cloud computing.

[0035] In one embodiment of this application, the method for generating pointer effects can run on a local terminal device or a server. When the method for generating pointer effects runs on a server, it can be implemented and executed based on a cloud interaction system, which includes a server and client devices.

[0036] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device as an example. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0037] The first aspect of this application provides a method for generating pointing marker effects. Please refer to [link / reference]. Figure 1 The specific process for generating this pointing icon effect can be summarized in steps 101 to 104:

[0038] Step 101: Determine the emitting object of the pointing marker effect to be generated, and the target object of the effect.

[0039] The aforementioned directional marker effect to be generated is a directional visual effect (VFX) that needs to be generated. The emitting object of the aforementioned effect is the object corresponding to the starting point of the directional marker effect, and the target object of the aforementioned effect is the object corresponding to the ending point of the directional marker effect.

[0040] It should be noted that the pointing mark effect generation method provided in this application embodiment generates a pointing mark effect that can display the pointing relationship between the two in a scene that has already been built with an effect emitting object and an effect target object.

[0041] In one application scenario, the aforementioned determination of the effect emitting object corresponding to the pointing marker effect to be generated, and the effect target object, includes:

[0042] Use the object with the curve rendering component as the effect emission object.

[0043] The control interface of the above curve rendering component is displayed. The control interface includes a setting control for the pointing mark effect to be generated, and the setting control includes a setting control for the target object of the effect.

[0044] The target object for the special effects is determined by setting the control based on the target object for the special effects described above.

[0045] The aforementioned curve rendering component is a curve rendering script component mounted on the effect emitting object. The settings controls in the control interface of this curve rendering component are used to set and adjust control parameters during the generation of the pointing indicator effect. It should be noted that the aforementioned curve rendering component may include one or more control interfaces, each with at least one settings control, but this is not a specific limitation.

[0046] In this embodiment, a basic game scene for implementing directional VFX effects is used as an example for illustration. Figure 2 This is a schematic diagram of a basic game scene provided in an embodiment of this application. For example... Figure 2 As shown, in this basic game scene, only two object objects are set: one as the effect emitting object and the other as the effect target object. In this embodiment of the application, as... Figure 2 As shown, Figure 2 The cube model object in the image is used as the target emission object for the special effects, and a curve rendering component is attached to the target emission object. The curve rendering component's control interface is used to specify... Figure 2 The cylindrical object in the model serves as the target object for the special effect.

[0047] It should be noted that the specific models of the two objects mentioned above can be arbitrarily replaced according to actual needs, and the selection of the special effect emitting object and the special effect target emitting object can be determined and adjusted according to actual needs, and is not a specific limitation here.

[0048] It should be further explained that in more complex game scenes, there are multiple object objects. Curve rendering components can be attached to each object object, meaning that each object object can act as an effect emission object. The corresponding effect target object is determined based on the curve rendering component attached to it, and the generation of the pointing marker effect is controlled.

[0049] Step 102: Obtain the position information of the above-mentioned special effect emitting object and the above-mentioned special effect target object, as well as the first curve generation parameters corresponding to the pointing mark special effect to be generated.

[0050] The position information of the special effect launching object is used to indicate the position of the special effect launching object in the game scene, and the position information of the special effect target object is used to indicate the position of the special effect target object in the game scene. The first curve generation parameters include parameters for controlling the pointing curve between the special effect launching object and the special effect target object. For example, it may include the launching angle of the pointing identification effect, the initial launching speed, and the curve equation for controlling the shape of the pointing curve, which are not specifically limited here.

[0051] Step 103: Based on the first curve generation parameters and the position information of the special effect emitting object and the special effect target object, generate a pointing curve from the special effect emitting object to the special effect target object.

[0052] It should be noted that there are several ways to generate a directional curve. For example, the directional curve can be directly generated by rendering in the corresponding coordinate system (a pre-established coordinate system in the game scene) based on the curve equation and other parameters. Alternatively, the position of each sampling point can be determined based on the curve equation and other parameters, and then the directional curve can be obtained by fitting the curve.

[0053] In this embodiment, a scheme using sampling points for fitting is used as an example for specific explanation, but it is not intended to be a specific implementation. The above-mentioned generation of a pointing curve from the special effects emitting object to the special effects target object, based on the parameters generated by the first curve and the position information of the special effects emitting object and the special effects target object, includes:

[0054] Obtain the sampling time interval corresponding to the pointing curve to be generated;

[0055] Based on the above sampling time interval, the above first curve generation parameters, and the position information of the above special effects emitting object and the above special effects target object, the position information of multiple basic sampling points between the above special effects emitting object and the above special effects target object is calculated.

[0056] The aforementioned pointing curve is obtained by fitting the location information of the aforementioned basic sampling points.

[0057] The aforementioned sampling time interval is used to control the density of sampling points on the directional curve to be generated. The sampling time interval can be set and adjusted according to actual needs, and no specific limitation is made here.

[0058] It should be noted that, in order to obtain more flexible and richer directional indicator effects, and to achieve flexible adjustment of indicator display effects, the above-mentioned directional curve can also be perturbed according to the perturbation curve to obtain a better curve display effect.

[0059] In one application scenario, multiple disturbance curves can be generated, and the direction curve can be controlled by combining these multiple disturbance curves. In this embodiment of the application, the generation of a single disturbance curve is used as an example for specific explanation, but this is not intended to be a specific limitation.

[0060] Specifically, before performing step 104, the above method also includes:

[0061] Obtain the second curve generation parameters corresponding to the directional marker effect to be generated;

[0062] Based on the second curve generation parameters and the position information of the special effects emitting object and the special effects target object, a perturbation curve is generated from the special effects emitting object to the special effects target object.

[0063] The above perturbation curve is superimposed on the above pointing curve to obtain the perturbated pointing curve.

[0064] The parameters for generating the second curve mentioned above may include the curve equation corresponding to the disturbance curve and other required control parameters, which are not specifically limited here. It should be noted that the curve equation of the disturbance curve and the curve equation of the pointing curve can also be preset, which are not specifically limited here either.

[0065] In some embodiments of this application, generating a perturbation curve from the special effects emitting object to the special effects target object based on the second curve generation parameters and the position information of the special effects emitting object and the special effects target object includes:

[0066] Obtain the sampling time interval used when generating the aforementioned pointing curve;

[0067] Based on the above sampling time interval, the above second curve generation parameters, and the position information of the above special effect emitting object and the above special effect target object, the position information of multiple perturbation sampling points between the above special effect emitting object and the above special effect target object is calculated.

[0068] The above-mentioned disturbance curve is obtained by fitting the location information of the above-mentioned disturbance sampling points.

[0069] In this embodiment, the sampling time interval used to generate the perturbation curve is the same as the sampling time interval used to generate the pointing curve. Therefore, the projection positions of a perturbation sampling point on the perturbation curve and a basic sampling point on the pointing curve on the horizontal plane are the same, meaning the sampling points on the two curves correspond one-to-one. In one application scenario, the sampling time interval used to generate the perturbation curve may be different from the sampling time interval used to generate the pointing curve. In this case, the sampling on the two curves may not correspond one-to-one. When it is necessary to obtain the perturbation sampling point corresponding to the basic sampling point, the coordinate values ​​of the corresponding point on the perturbation curve can be determined based on the coordinates of the basic sampling point.

[0070] In some embodiments of this application, the aforementioned location information is location coordinates, and the aforementioned superimposing of the disturbance curve onto the pointing curve to obtain the disturbed pointing curve includes:

[0071] Obtain the disturbance coefficients corresponding to the above disturbance curves;

[0072] For each basic sampling point, the perturbation coordinates are calculated based on the perturbation coefficient and the position coordinates of the perturbation sampling point corresponding to the basic sampling point. The position coordinates of the basic sampling point are added to the perturbation coordinates to update the position coordinates of each basic sampling point.

[0073] The perturbation-adjusted pointing curve is obtained by fitting the position coordinates of the updated base sampling points.

[0074] The aforementioned disturbance coefficient is a parameter used to control the degree of disturbance influence of the disturbance curve on the pointing curve. Its specific parameter value can be set and adjusted according to actual needs, and is not specifically limited here.

[0075] It should be noted that the equations corresponding to the pointing curve and the disturbance curve can be set and adjusted according to actual needs. In this embodiment, the parabolic trajectory equation is used for the pointing curve and the Bézier curve equation is used for the disturbance curve as examples, but this is not intended to be a specific limitation.

[0076] Specifically, a pointing curve is generated based on the equation of parabolic trajectory. To account for potential gravitational effects on the pointing marker effect, the parabolic trajectory is calculated in real-time based on the positions of the launching and target objects of the effect, as well as the set launching angle. The vertical direction of the 3D space corresponding to the game scene is used as the y-axis (the specific coordinate axis direction can be found in [reference]). Figure 2 As shown), the equation of the parabolic trajectory is given by formula (1):

[0077]

[0078] Where x represents the coordinates of the base sampling point on the x-axis of the calculated pointing curve, y represents the coordinates of the base sampling point on the y-axis of the calculated pointing curve, and z represents the coordinates of the base sampling point on the z-axis of the calculated pointing curve. The angle θ is the emission angle from the emitting object of the pointing marker effect to be generated. x v y and v z These represent the components of the initial launch velocity v on the three coordinate axes. xz and dis y These represent the distances between the effect's emitting object and its target object on the xz and y axes, respectively. g is the preset gravitational acceleration. t is the sampling time determined based on the sampling time interval corresponding to the pointing curve.

[0079] Figure 3 This is a schematic diagram of a directional curve trajectory provided in an embodiment of this application, such as... Figure 3 As shown, as the sampling time changes, the coordinate values ​​corresponding to different basic sampling points can be calculated, thereby fitting a parabolic pointing curve.

[0080] Furthermore, in order to achieve flexible curve effects such as perturbations in VFX special effects, this embodiment of the application also simulates and generates perturbation curves based on the Bézier curve equation. Specifically, the nth-order Bézier curve equation is shown in the following formula (2):

[0081]

[0082] Where t is the sampling time determined based on the sampling time interval corresponding to the pointing curve. n (t) is a point with a relative position t in an n-order Bézier curve, b j These are the control points of the Bézier curve. It is a Béssel polynomial. Specifically, the Béssel polynomial is shown in formula (3) below:

[0083]

[0084] In this embodiment of the application, the curve rendering component used is a curve rendering script component based on the C# programming language. In the C# script, the Bézier curve trajectory can be calculated by setting the control points of the Bézier curve in the engine and setting the order n of the Bézier curve.

[0085] Figure 4 This is a schematic diagram of the trajectory of a Bézier curve provided in an embodiment of this application, such as... Figure 4 As shown, the trajectory of the generated Bézier curve is... Figure 3 The parabolic trajectory shown is more flexible. Therefore, the parabola can be perturbed using Bézier curves to obtain a more flexible curve display effect.

[0086] It should be noted that Bézier curves can also be used as directional curves, and a single curve trajectory can be used to render and generate directional marker effects. Other curve trajectories can also be used, without specific limitations here.

[0087] In this embodiment, a Bezier curve (perturbation curve) is superimposed on a parabola (pointing curve) to obtain a perturbed pointing curve. The superposition method is shown in the following formula (4):

[0088] p VFX (t)=p parabola (t)+αp bessel (t) (4)

[0089] Where, p VFX (t) represents the spatial location of the base sampling point after the perturbation at time t, p parabola (t) represents the spatial location of the base sampling point before the disturbance at time t (the location of the curve trajectory point calculated from the parabola), p bessel (t) represents the spatial location of the disturbance sampling point at time t (the location of the trajectory point calculated from the Bézier curve), and α represents the disturbance coefficient that controls the intensity of the Bézier curve disturbance. The value of the disturbance coefficient can be set and adjusted according to actual needs, and is not specifically limited here.

[0090] Step 104: Obtain the rendering parameters of the above-mentioned pointing curve, and render the above-mentioned pointing curve according to the above-mentioned rendering parameters to obtain the pointing mark effect.

[0091] The rendering parameters of the aforementioned pointing curve are parameters that correspond to the pointing curve and are used to control the rendering effect of the pointing mark effect. The specific rendering parameters can be set and adjusted according to actual needs, and no specific limitations are made here.

[0092] In this embodiment of the application, the above-mentioned rendering parameters can also be obtained through the setting controls in the control interface of the curve rendering component. Specifically, the above-mentioned rendering parameters include material parameters; the above-mentioned setting controls also include material parameter setting controls.

[0093] The above-mentioned method obtains the rendering parameters of the pointing curve, and renders the pointing curve according to the rendering parameters to obtain the pointing indicator effect, including:

[0094] Obtain material parameters using the control set according to the above material parameters;

[0095] The aforementioned curve rendering component renders the aforementioned directional curve according to the aforementioned material parameters to obtain the aforementioned directional marker effect.

[0096] Specifically, the control interface of the curve rendering component has multiple setting controls, and the curve rendering component can set one or more control interfaces. In this embodiment, the example of the curve rendering component having multiple control interfaces is used for illustration.

[0097] Figure 5 This is a schematic diagram of a control interface for the curve rendering component provided in an embodiment of this application. Figure 6 This is another schematic diagram of the control interface of the curve rendering component provided in the embodiments of this application. Figure 7 This is another schematic diagram of the control interface of the curve rendering component provided in the embodiments of this application.

[0098] like Figures 5 to 7 As shown, multiple setting controls are located in different control interfaces. Specifically, different parameters can be obtained through different setting controls, and users can adjust these parameters through each control, thus making it easier and more flexible to adjust the generated pointing marker effects. Specifically, controls can be set for target object settings, material parameters, emission angles, disturbance coefficients (used to adjust Bézier curve weights), Bézier control points, etc. Other setting controls can also be set as needed, without specific limitations here.

[0099] By using the various settings controls in the control interface of the curve rendering component attached to the effect's emitting object, you can set various parameters required for generating the pointing marker effect. For example, you can select the effect's target object, adjust the generation parameters of the pointing curve and perturbation curve, specify the effect material by adjusting the line material parameters, modify the emission angle of the parabola emitted by the VFX by adjusting the emission angle parameters, add control points for the Bézier curve by clicking the "Add Bézier Curve Control Point" button, and adjust the intensity of the Bézier curve's interference with the parabola by modifying the "Bézier Curve Weight α".

[0100] In one application scenario, the material parameters mentioned above in the rendering parameters can be used to control material color, material texture, etc. Rendering parameters can also include curve segment length, used to control the length of a unit curve material segment in curve rendering. Other parameters can also be set according to actual needs, without specific limitations here.

[0101] Figure 8 This is a schematic diagram of a directional marker effect provided in an embodiment of this application. Figure 9 This is a schematic diagram of another directional marker effect provided in an embodiment of this application. Wherein, Figure 8 The center is a directional indicator effect that has not been processed by superimposing a perturbation curve. Figure 9 The first effect is a directional marker effect processed by overlaying a perturbation curve (this can be achieved by adjusting the perturbation coefficient), and the second effect uses different rendering materials (this can be achieved by adjusting the material parameters). Figure 8 and Figure 9 As shown, according to the method for generating directional marker effects in this application embodiment, different display effects of directional marker effects can be generated simply by adjusting the parameters. The adjustment is flexible and the generation efficiency is high.

[0102] Therefore, when building a game scene, you only need to attach a curve rendering component to the effect emission object. The curve equation can then be calculated numerically in a C# script, achieving dynamic 3D curve VFX effects with low performance overhead using only a simple 3D curve model and an effect material renderer script (shader). Effects designers can adjust the curve model's parameters through the curve rendering script's UI panel (control interface) to achieve flexible and variable trajectory pointing effects, improving the efficiency of fine-tuning the VFX.

[0103] The solution adopted in this application embodiment can determine the effect emitting object and the effect target object corresponding to the directional marker effect to be generated; obtain the position information of the effect emitting object and the effect target object, as well as the first curve generation parameters corresponding to the directional marker effect to be generated; generate a directional curve from the effect emitting object to the effect target object based on the first curve generation parameters and the position information of the effect emitting object and the effect target object; obtain the rendering parameters of the directional curve, and render the directional curve according to the rendering parameters to obtain the directional marker effect. Thus, by obtaining only the required parameters, a directional curve can be generated based on the position information of the effect emitting object and the effect target object, as well as the first curve generation parameters corresponding to the directional marker effect to be generated. The directional marker effect can then be obtained by rendering the directional curve using the rendering parameters, eliminating the need to set and process a two-dimensional timing diagram, which is beneficial for improving the generation efficiency of the directional marker effect.

[0104] This embodiment also provides a directional sign effect generation device, which can be integrated into a terminal device. For example... Figure 10 As shown, the pointing sign effect generation device may include:

[0105] The object determination module 1001 is used to determine the special effect emitting object corresponding to the pointing mark special effect to be generated, and the special effect target object.

[0109] In an optional example, the aforementioned pointing marker effect generation device further includes a curve perturbation module for:

[0110] Obtain the second curve generation parameters corresponding to the directional marker effect to be generated;

[0111] Based on the second curve generation parameters and the position information of the special effects emitting object and the special effects target object, a perturbation curve is generated from the special effects emitting object to the special effects target object.

[0112] The above perturbation curve is superimposed on the above pointing curve to obtain the perturbated pointing curve.

[0120] The above-mentioned disturbance curve is obtained by fitting the location information of the above-mentioned disturbance sampling points.

[0121] In an optional example, the above location information is location coordinates, and the curve perturbation module is also specifically used for:

[0122] For each basic sampling point, the perturbation coordinates are calculated based on the perturbation coefficient and the position coordinates of the perturbation sampling point corresponding to the basic sampling point. The position coordinates of the basic sampling point are added to the perturbation coordinates to update the position coordinates of each basic sampling point.

[0123] The perturbation-adjusted pointing curve is obtained by fitting the position coordinates of the updated base sampling points.

[0124] In an optional example, the object determination module 1001 described above is specifically used for:

[0127] The target object for the special effects is determined by setting the control based on the target object for the special effects described above.
