[0034] Currently, manually configuring invisible walls is very complex and time-consuming, significantly impacting the efficiency of building them. Therefore, this disclosure provides a method, apparatus, device, and medium for generating invisible walls in a virtual environment. For ease of understanding, the embodiments of this disclosure are described below.

[0035] Figure 1 This flowchart illustrates a method for generating an invisible wall in a virtual environment, as provided in this disclosure. This method can be executed by a device for generating an invisible wall in a virtual environment, which can be implemented using software and / or hardware. (Refer to...) Figure 1 The method for generating an air wall in a virtual environment may include the following steps.

[0036] In step S102, in response to the user's click operation, a virtual ray perpendicular to the user interface is emitted from the click position of the click operation.

[0037] Understandably, a viewpoint is required for rendering a virtual scene, from which the user observes the virtual scene. 3D graphics systems typically use a camera to represent the user's viewpoint and define the user's relative position and orientation relative to the virtual scene. The camera's direction, from near to far, forms the near clipping plane and the far clipping plane. The near clipping plane is the user interface, and the near and far clipping planes form a 3D viewport, within which the 3D virtual scene is rendered.

[0038] In this embodiment, in response to a user's click operation, a virtual ray perpendicular to the user interface (i.e., near the clipping plane) can be emitted from the click location in the 3D viewport. The click operation typically refers to a mouse click, touch click, or similar action on the user interface.

[0039] Step S104: Detect the intersection points of the virtual ray and the boundary region in the virtual scene to obtain multiple intersection point positions.

[0040] The virtual ray, emanating from the user interface and traveling to the far clipping plane, intersects with boundary regions in the virtual scene within the 3D viewport. Based on this, multiple intersection points between the virtual ray and the boundary regions in the virtual scene are detected.

[0041] Referring to the above embodiment, multiple intersection points are obtained based on multiple click operations; such as Figure 2 The example shows four intersection points, each of which can be represented by a three-dimensional position vector.

[0042] Step S106: Between every two adjacent intersection points, configure the model parameters of the preset cube model according to the intersection point positions to generate a collision body.

[0043] In this embodiment, the cube model can be understood as a unitary cube with initialized length, width, height, and angle parameters. For ease of configuration, the initial position and angle are typically set to (0,0,0). For any pair of adjacent intersection points, the cube model's length, width, height, placement, and rotation angle can be configured based on these two intersection points to configure the cube model as a collider, which is used to form an air wall.

[0044] In one embodiment, to ensure that the air wall composed of colliders is impassable, a collider component can be added to the cube model. Specifically, the collider component can be configured on the cube model by calling the Unity physics engine, so that the colliders and air walls generated based on the cube model are impassable. After adding the collider component to the cube model, the colliders configured by it and the air walls composed of colliders can block the map boundary, preventing players from walking into areas where their movement is blocked.

[0045] Step S108: Form a closed air wall by combining multiple colliding bodies at the intersection point.

[0046] According to the above embodiments, a collider is generated between every two adjacent intersection points on the map of the virtual scene. Multiple consecutive colliders at the intersection points are combined to obtain a closed air wall.

[0047] The method for generating invisible walls in a virtual environment provided in this embodiment first responds to a user's click operation by emitting a virtual ray perpendicular to the user interface from the click location. It then detects the intersection points of the virtual ray with boundary regions in the virtual scene, obtaining multiple intersection points. Next, between every two adjacent intersection points, the model parameters of a preset cube model are configured according to the intersection points to generate colliders. Finally, multiple consecutive colliders at the intersection points form a closed invisible wall. This technical solution can quickly locate the intersection points of boundary regions in the 3D world using a ray collision detection method. The intersection points allow for automated configuration of the cube model's parameters, resulting in colliders and the enclosed invisible wall. The entire process eliminates the need for users to manually create and adjust the cube model, effectively improving the efficiency of invisible wall creation.

[0048] Regarding step S106, the following is a detailed description of an embodiment in which the model parameters of a preset cube model are configured according to the intersection point position to generate a collider.

[0049] In this embodiment, the model parameters include the placement position of the cube model; correspondingly, configuring the preset placement position of the cube model based on the intersection position can include:

[0050] Configure the center position of two adjacent intersection points as the placement position of the cube model; place the cube model at the placement position.

[0051] Specifically, the placement position Pos of the cube model in three-dimensional space is the position of two adjacent intersection points (p i p i+1 The sum of the three-dimensional position vectors of ) is half, as shown below:

[0052]

[0053] In this three-dimensional coordinate system, the x-axis represents the wall thickness, the y-axis represents the wall height, and the z-axis represents the wall length. In the above formula, p... i (x), p i+1 (x) represents the intersection point p. i p i+1 The position coordinates p in the x-axis direction i (y), p i+1 (y) represents the intersection point p. i p i+1 The position coordinates p in the y-axis direction i (z), p i+1 (z) represents the intersection point p. i p i+1 Position coordinates in the z-axis direction.

[0054] When placing a cube model at the placement position Pos, you can use the cube model's preset anchor point position (such as the center point) as a reference to make the anchor point position coincide with the placement position Pos.

[0055] In this embodiment, the model parameters include the rotation angle of the cube model; correspondingly, configuring the preset rotation angle of the cube model according to the intersection point position can include:

[0056] The orientation of the cube model in the virtual scene is determined based on the three-dimensional position vectors of two adjacent intersection points.

[0057] Specifically, the orientation Dir of the cube model in the 3D virtual scene is the result of subtracting the 3D position vectors of two adjacent intersection points (pi, pi+1):

[0058]

[0059] Based on the quaternion and the placement direction, generate the rotation angle of the cube model; determine the central axis of the cube model in the height direction as the first rotation axis; rotate the cube model from the preset original angle to the rotation angle around the first rotation axis.

[0060] Using quaternions and the cube model's orientation Dir in 3D space, calculate the rotation angle required for the cube model to rotate in 3D space, and rotate the cube model in the height direction according to the rotation angle, while keeping the width and length directions of the cube model unchanged.

[0061] The quaternions described above can represent the rotation of an object around any vector axis, and compared with the methods of Euler angle rotation and rotation matrices, they are more efficient and more flexible in operation. Quaternions are all composed of real numbers plus three imaginary units i, j, and k, and they have the following relationship: i 2 =j 2 =k 2 =-1, i°=j°=k°=1, each quaternion is a linear combination of 1, i, j, and k, that is, a quaternion can generally be represented as a+bi+cj+dk, where a, b, c, and d are real numbers. The geometric meaning of i, j, and k in a quaternion can be understood as a kind of rotation, as follows: i rotation represents the rotation from the positive Z-axis to the positive Y-axis in the plane where the Z-axis intersects the Y-axis; j rotation represents the rotation from the positive X-axis to the positive Z-axis in the plane where the X-axis intersects the Z-axis; k rotation represents the rotation from the positive Y-axis to the positive X-axis in the plane where the Y-axis intersects the X-axis; -i, -j, and -k represent the reverse rotations of i, j, and k, respectively.

[0062] In this embodiment, the model parameters include the wall dimensions of the cube model, which include wall length, wall thickness, and wall height. Accordingly, when configuring the wall dimensions of the preset cube model according to the intersection position, it is necessary to scale the three wall dimensions of wall length, wall thickness, and wall height. This can be referred to as shown below.

[0063] In the length direction, the cube model needs to fill the length gap between two intersection points, and the length gap between any two intersection points is not fixed; based on this, this embodiment can scale the length of the wall so that the scaled wall length matches the length gap between the two intersection points.

[0064] In this embodiment, the original length of the cube model can be obtained; the scaling ratio is determined based on the length between two adjacent intersection points and the original length; wherein the length between two adjacent intersection points is the modulus of the vector of the placement direction Dir. According to the scaling ratio, the cube model is scaled from the original length to the wall length; the scaled wall length is equal to the length between the two intersection points, so that the cube model can completely fill the space between the two intersection points.

[0065] In this embodiment, the wall height can be a preset height value, and the cube model is configured to the preset height value in the height direction. The wall thickness can be a preset thickness value, and the cube model is configured to the preset thickness value in the thickness direction; or, a thickness scaling ratio can be preset, and the initial original wall thickness of the cube model is scaled according to the preset scaling ratio.

[0066] Configure the wall dimensions of the cube model to obtain colliders with wall length, wall thickness, and wall height. In order for them to form a complete air wall, the wall thickness and wall height are equal between different colliders, while the wall length matches the length between the intersection points and can be different for each other.

[0067] It is understood that in the above multiple embodiments of configuring the model parameters of the cube model, there is no limitation on the configuration order of various model parameters such as placement position, wall size (length, thickness and height) and rotation angle, and different configuration orders will not affect the generated collision body after configuration.

[0068] Based on the above embodiments, colliders are continuously created between two adjacent intersection points, thereby creating an invisible wall that the player cannot pass through between multiple consecutive intersection points. The invisible wall can be referenced as follows: Figure 3 Example.

[0069] In a virtual environment, when a player collides with an invisible wall, a collision effect can be displayed at the point of impact to indicate that the area ahead is impassable. Based on this, this embodiment can provide the following method, including:

[0070] (I) In response to the user's click operation, emit a virtual ray perpendicular to the user interface from the click position;

[0071] (II) Detect the intersection points of the virtual ray and the boundary region in the virtual scene to obtain multiple intersection point positions;

[0072] (III) Between every two adjacent intersection points, configure the model parameters of the preset cube model according to the intersection point positions to generate a collider;

[0073] (IV) Form a closed air wall by combining multiple colliding bodies at the intersection point;

[0074] (V) When the target object collides with the invisible wall in the virtual scene, the preset collision effect is displayed at the corresponding collision point on the invisible wall.

[0075] An example of displaying preset collision effects at the corresponding collision points on the air wall can be found below.

[0076] First, the target collider that collides with the target object within the invisible wall is obtained, along with the anchor point position of the target collider and the first direction in which the target collider faces. The target collider is a cube with the target wall's length, thickness, and height. When the target object collides with the invisible wall in the virtual scene, the target collider at the collision point within the invisible wall, the anchor point position of the target collider, and the first direction in which the target collider faces are determined. The anchor point position is also the target collider's placement position Pos; the first direction is also the target collider's placement direction Dir. The target object can be, for example, a player-controlled character, vehicle, or other virtual object that can move on the ground.

[0077] Then, based on the target object's position and anchor point position, a second direction for the target object to move towards the target collider is determined. Specifically, the subtraction of the three-dimensional position vector between the anchor point position of the target collider and the target object's position is used as the reference direction for the target object to move towards the invisible wall (or the target collider). Considering that the target object will not move in the height direction when moving towards the invisible wall, the value of the reference direction in the height direction is set to 0, thus obtaining the second direction for the target object to move towards the target collider.

[0078] An angle is formed between the first direction in which the target collider faces and the second direction in which the target object moves toward the target collider, thereby determining the first included angle between the first and second directions; wherein, the first included angle is an acute angle. Two complementary included angles are formed between the first and second directions, and in this embodiment, the acute angle is taken as the first included angle.

[0079] The second included angle is determined based on the tangent between the thickness and length of the target wall on the bottom surface of the target collider. Specifically, the tangent between the thickness and length of the target wall on the rectangular bottom surface can be calculated first, and then the second included angle can be calculated based on the tangent.

[0080] Next, the pre-configured surface on the target collider is rotated according to the first included angle and the second included angle; the surface is used to bind the collision effect and is completely attached to the air wall.

[0081] In this embodiment, when the first included angle is greater than the second included angle, the central axis of the target collider in the thickness direction of the target wall is determined as the second rotation axis, and the pre-configured surface on the target collider is rotated vertically around the second rotation axis; and the central axis of the target collider in the length direction of the target wall is determined as the third rotation axis, and the surface is rotated vertically around the third rotation axis.

[0082] When the first included angle is not greater than the second included angle, the pre-configured surface on the target collider is rotated vertically around the second rotation axis.

[0083] After rotating the face as described above, the collision effects bound to the face also rotate accordingly. Therefore, the collision effects bound to the rotated face are then displayed. Figure 4 In the example, the collision effect is displayed as a mesh in the form of particle effects.

[0084] In summary, the method for generating invisible walls in a virtual environment provided in this embodiment can automatically configure model parameters such as the placement, rotation angle, and wall dimensions of a cube model using intersection points. This eliminates the need for users to manually create and adjust the cube model, achieving fully automated creation and effectively improving the efficiency of invisible wall creation. When a target object collides with an invisible wall in the virtual scene, a preset collision effect is displayed at the corresponding collision point on the wall. This not only provides timely feedback to the player but also adds to the fun by showcasing the collision effects.
