Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method and device for synthesizing footstep sound effects in a game scene, and an electronic device. Background Art

[0002] With the development of the gaming industry, players' requirements for sound are becoming increasingly higher. The real-time sound feedback of characters' footsteps in complex exploration scenes is becoming increasingly important. However, current games pay relatively little attention to sound effects. Many use a design method that uses music to fill the entire scene, resulting in the footstep sound effects often being inaudible. Therefore, most games also have relatively simple footstep designs. For example, existing technical solutions use a simple switch to associate the floor material to control the playback of the sound corresponding to the current floor material, or only use Real-time Parameter Controls (RTPCs) to control the volume and high and low pass values ​​of the footstep sound effects of the current floor material. However, either method will make the footsteps in the game scene on rainy days less realistic. Summary of the Invention

[0006] Optionally, adjusting the volume of the first footsteps and the volume of the second footsteps based on the current rainfall includes: determining a trend of the current rainfall, wherein the trend includes the current rainfall increasing and the current rainfall decreasing; when the trend indicates that the current rainfall is increasing, linearly reducing the volume of the first footsteps and linearly increasing the volume of the second footsteps based on the trend; and when the trend indicates that the current rainfall is decreasing, linearly increasing the volume of the first footsteps and linearly reducing the volume of the second footsteps based on the trend.

[0007] Optionally, the method further includes: increasing a low-pass cutoff frequency of the first footsteps when the volume of the first footsteps is increased; and decreasing a low-pass cutoff frequency of the first footsteps when the volume of the first footsteps is decreased.

[0009] Optionally, obtaining the current rainfall in the game scene includes: determining the current accumulated rainfall in the game scene based on target parameters, wherein the target parameters include: rainfall intensity and rainfall duration, or the target parameters include: rainfall intensity, rainfall duration and water permeability of the terrain material in the game scene; and determining the accumulated rainfall as the current rainfall.

[0010] Optionally, the game scene is determined according to the current position of the virtual character; and the first footsteps are selected according to the terrain material of the game scene and / or the second footsteps are selected according to the terrain material of the game scene.

[0011] In a second aspect of the implementation of the present application, a device for synthesizing footstep sound effects in a game scene is provided, comprising: an acquisition module for acquiring the current rainfall in the game scene, wherein the game scene has a footstep sound effect including a first footstep, and the first footstep refers to a footstep produced in a non-raining scene; an adding module for adding a second footstep to the game scene when the current rainfall exceeds a preset rainfall value, wherein the second footstep refers to a footstep produced in a raining scene; a first adjustment module for adjusting the volume of the first footstep and the volume of the second footstep based on the current rainfall, wherein the volume of the first footstep is negatively correlated with the volume of the second footstep; and a synthesis module for synthesizing the first footstep with the adjusted volume and the second footstep with the adjusted volume into the current footstep sound effect in the game scene.

Since the volume of the first footstep is negatively correlated with the volume of the second footstep, that is, in the rainy scene, the second footstep will be reduced while the first footstep is increased, or the second footstep will be increased while the first footstep is reduced. In other words, the superposition of footsteps in the game scene of the present application is more in line with the sound auditory effect of rainy footsteps in the real world, thereby solving the problem of poor auditory realism of footsteps in rainy days in game scenes in the prior art.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] In the following description, the suffixes such as "module" and "unit" used to represent elements are only used to facilitate the description of this application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0022] The embodiment of the present application provides a method for synthesizing footstep sound effects in a game scene, such as Figure 1 Shown, including:

[0023] Step 102: obtaining the current rainfall in the game scene, wherein the game scene includes a footstep sound effect of a first footstep, and the first footstep refers to a footstep sound produced in a scene where it is not raining;

[0024] It should be noted that the rainfall in the game scene involved in the embodiments of the present application can be similar to the rainfall in the real scene. For example, in the real world, light rain refers to a rainfall process with less than 5 mm of precipitation within 12 hours or less than 10 mm of precipitation within 24 hours; moderate rain refers to a rainfall process with 5 to 15 mm of precipitation within 12 hours or 10 to 25 mm of precipitation within 24 hours; heavy rain refers to a rainfall process with 15 to 30 mm of precipitation within 12 hours or 25 to 50 mm of precipitation within 24 hours; rainstorm refers to a rainfall process with 30 to 70 mm of precipitation within 12 hours or 50 to 100 mm of precipitation within 24 hours; heavy rainstorm refers to a rainfall process with 70 to 140 mm of precipitation within 12 hours or 100 to 250 mm of precipitation within 24 hours; and extremely heavy rainstorm refers to a rainfall process with more than 140 mm of precipitation within 12 hours or more than 250 mm of precipitation within 24 hours. In the game scene, similar settings can be made for the rainfall level based on the real scene, or corresponding settings can be made according to the specific game scene.

[0025] In addition, it should be noted that the game scene in the embodiment of the present application corresponds to the location of the virtual character in the game, that is, the current rainfall in the game scene refers to the local area centered on the location of the virtual character. This method can further reduce the error of the current rainfall. Because in the game, there may be obstructions above the location of the virtual character. If there are obstructions, the current rainfall at the location of the virtual character needs to take the rain-shielding effect of the obstructions into account, rather than directly referring to the rainfall at other locations without obstructions. This method can further simulate the real-world scene and provide gamers with a more realistic gaming experience.

[0026] Step 104, when the current rainfall exceeds the preset rainfall value, adding a second footstep to the game scene, wherein the second footstep sound refers to the footstep sound generated in the rain scene;

[0027] Step 106, adjusting the volume of the first footstep and the volume of the second footstep based on the current rainfall, wherein the volume of the first footstep is negatively correlated with the volume of the second footstep; and

[0028] It's important to note that the first footstep sound won't occur in low rainfall conditions, such as a light rain of only 3mm. Therefore, the volume of the first and second footstep sounds in the game scene will be adjusted only when the current rainfall exceeds a preset value, to better reflect the real world. Furthermore, the second footstep sound is determined based on factors such as the floor texture, the avatar's body shape (sound effects like a robot swinging its arm), and its movement state (walking, running).

[0029] Step 108 : synthesize the first footstep sound after the volume is adjusted and the second footstep sound after the volume is adjusted into the current footstep sound effect in the game scene.

[0030] Through the above steps 102 to 108, since the game scene includes the footstep sound effect of the first footstep, and when the current rainfall in the game scene exceeds the preset rainfall value, a second footstep will be added to the game scene, and then the volume of the first footstep generated in the rainy scene and the volume of the second footstep generated in the non-rainy scene are adjusted based on the current rainfall, and then the first footstep with adjusted volume and the second footstep with adjusted volume are combined into the footstep sound effect in the game scene. Since the volume of the first footstep is negatively correlated with the volume of the second footstep, that is, in the rainy scene, the second footstep will be reduced while the first footstep is increased, or the second footstep will be increased while the first footstep is reduced. In other words, the superposition of footsteps in the game scene of the present application is more consistent with the sound auditory effect of rainy footsteps in the real world, thereby solving the problem of poor auditory realism of footsteps in rainy days in game scenes in the prior art.

[0031] In addition, from the perspective of enhancing realism, for the situation where the current rainfall does not exceed the preset rainfall value and is greater than zero, the influence of rain on footsteps can be simulated by adjusting the low-pass cutoff frequency of the first footsteps (corresponding to the footsteps generated in the non-raining scene). For example, when the process changes from no rain to rainfall, the low-pass cutoff frequency of the first footsteps can be appropriately lowered when the current rainfall does not exceed the preset rainfall value and is greater than zero, making the first footsteps sound more dull. In the process from rainfall to no rain, the low-pass cutoff frequency of the first footsteps can be appropriately increased when the current rainfall does not exceed the preset rainfall value and is greater than zero.

[0032] In an optional implementation manner of the embodiment of the present application, the method of adjusting the volume of the first footstep sound and the volume of the second footstep sound based on the current rainfall involved in step 104 may further include:

[0033] Step 11, determining the rainfall range into which the current rainfall falls; and

[0034] Step 12: adjusting the volume of the first footstep sound to a first volume corresponding to the rainfall range based on the mapping relationship, and adjusting the volume of the second footstep sound to a second volume corresponding to the rainfall range;

[0035] The mapping relationship is used to represent the mapping relationship between the rainfall range, the volume of the first footstep, and the volume of the second footstep; the rainfall range is negatively correlated with the volume of the first footstep, and the rainfall range is positively correlated with the volume of the second footstep.

[0036] In the above steps 11 and 12, in a specific example, the rainfall range may include: 0-25 mm for light rain, 25-50 mm for moderate rain, 50-75 mm for heavy rain, and 75-100 mm for torrential rain. Furthermore, the first footstep sound corresponding to light rain is 40 decibels, and the second footstep sound is 30 decibels; the first footstep sound corresponding to moderate rain is 50 decibels, and the second footstep sound is 20 decibels; the first footstep sound corresponding to heavy rain is 60 decibels, and the second footstep sound is 15 decibels; and the first footstep sound corresponding to torrential rain is 60 decibels, and the second footstep sound is 10 decibels. If the preset rainfall value is 10mm and the current rainfall is 40mm, the current rainfall falls within the rainfall range of 25-50mm. At this time, the first footstep sound needs to be adjusted to 40 decibels and the second footstep sound needs to be adjusted to 30 decibels. If the current rainfall is 60mm, the current rainfall falls within the rainfall range of 50-75mm. At this time, the first footstep sound needs to be adjusted to 60 decibels and the second footstep sound needs to be adjusted to 15 decibels.

[0037] It can be seen that the method in the above steps 11 and 12 is a nonlinear adjustment of the first footstep and the second footstep according to the current rainfall. This method directly adjusts the first footstep and the second footstep according to the rainfall range into which the current rainfall falls. It is not only convenient and fast but also conforms to the sound effect of footsteps in rain scenes in the real world.

[0038] It should be noted that the above rainfall range and the specific corresponding first footstep sounds and second footstep sounds are merely examples, and can be set accordingly according to actual needs in different game scenarios.

[0039] In another optional implementation of the embodiment of the present application, the method of adjusting the volume of the first footstep sound and the volume of the second footstep sound based on the current rainfall involved in step 104 may further include:

[0040] Step 21, determining the trend of the current rainfall, wherein the trend includes the current rainfall being increasingly heavier and the current rainfall being increasingly lighter;

[0041] Step 22, when the trend indicates that the current rainfall is increasing, linearly reduce the volume of the first footstep sound and linearly increase the volume of the second footstep sound based on the trend;

[0042] Step 23 : When the trend indicates that the current rainfall is decreasing, the volume of the first footsteps is linearly increased and the volume of the second footsteps is linearly decreased based on the trend.

[0043] As can be seen from steps 21 through 23 above, the first and second footsteps are linearly adjusted based on the current rainfall trend. Specifically, as long as the current rainfall increases, the volume of the second footstep increases and the volume of the first footstep decreases in real time. In a specific example, the current rainfall trend and the first footstep can form a preset direct proportional function, while the current rainfall trend and the second footstep can form a preset inverse proportional function. The constants in the direct and inverse proportional functions can be set accordingly based on actual conditions. Because steps 21 through 23 linearly adjust the first and second footsteps in real time based on the current rainfall trend, they better align with the footstep sound effects of a real-world rainy scene compared to the nonlinear adjustment of the first and second footsteps in steps 11 and 12 above.

[0044] It should be noted that the current amount of rain decreasing in the embodiments of the present application can refer to the amount of rain decreasing, for example, from heavy rain to moderate rain, and then from moderate rain to light rain. Alternatively, in the current game scene, there is an obstruction above the game player that can block the rain, but the obstruction cannot completely block the rain. However, the rain at this time is smaller than when there is no obstruction. In this game scene where the current amount of rain is decreasing, the first footstep sound and the second footstep sound are gradually changed, that is, the volume of the first footstep sound gradually increases, and the volume of the second footstep sound gradually decreases. If the current amount of rain decreases until it stops raining, the first footstep sound can be directly eliminated.

[0045] In an optional implementation of the embodiment of the present application, the method of the embodiment of the present application may further include:

[0046] Step 31, increasing the low-pass cutoff frequency of the first footsteps while increasing the volume of the first footsteps; and

[0047] Step 32: While reducing the volume of the first footsteps, reduce the low-pass cutoff frequency of the first footsteps.

[0048] For the low-pass cutoff frequency involved in the embodiments of the present application, the frequency below a certain frequency is the passband, and the frequency above a certain frequency is the stopband. Therefore, increasing the low-pass cutoff frequency of the first footsteps means increasing the cutoff frequency, that is, the frequency range of the passband is wider and the frequency range of the stopband is narrower; conversely, reducing the low-pass cutoff frequency of the first footsteps means reducing the cutoff frequency, that is, the frequency range of the passband is narrower and the frequency range of the stopband is wider.

[0049] In another optional implementation of the embodiment of the present application, after the first footstep sound with the adjusted volume and the second footstep sound with the adjusted volume are synthesized into the footstep sound effect in the game scene, such as Figure 2 As shown, the method steps of the embodiment of the present application may also include:

[0050] Step 110 : Adjust the first footstep sound and the second footstep sound after the volume adjustment again based on the same adjustment ratio of the game scene sound.

[0051] It can be seen that if the overall scene sound effects in the game scene change, the first and second footstep sounds after adjusting the volume also need to be adjusted accordingly. For example, if the volume of the game background sound effects increases by 30%, the first and second footstep sounds after adjusting the volume also need to be increased by 30%. If the volume of the game background sound effects decreases by 20%, the first and second footstep sounds after adjusting the volume also need to be decreased by 20%. This ensures that the synthesized footstep sound effects are consistent with the changes in the overall game scene sound effects, ensuring the integrity of the entire game sound effects.

[0052] In an optional implementation of the embodiment of the present application, the method of obtaining the current rainfall in the game scene involved in the above step 102 may further include:

[0053] Step 41, determining the current accumulated rainfall in the game scene according to target parameters, wherein the target parameters include: rainfall intensity and rainfall duration, or the target parameters include: rainfall intensity, rainfall duration and water permeability of the terrain material in the game scene;

[0054] Step 42: Determine the accumulated rainfall as the current rainfall.

[0055] It should be noted that the rainfall intensity in the embodiments of the present application needs to consider whether there is an obstruction above the virtual character that can block the rain, that is, the rainfall intensity refers to the rainfall intensity after passing through the obstruction. For example, it refers to the rainfall intensity after the weighted rainfall intensity of the sky in the actual game, which is the result of multiplying the rainfall intensity of the sky by the weighted value, wherein the weighted value is less than 1 and is related to the obstruction effect of the obstruction above the virtual character's position, that is, if the obstruction has a good rain-blocking effect, the weighted value is smaller, and if the obstruction has a poor rain-blocking effect, the weighted value is smaller. The above-mentioned method of determining the rainfall intensity by weighting is only an example, and the rainfall intensity after passing through the obstruction can also be determined by other methods.

[0056] In addition, cumulative rainfall typically refers to the product of rainfall intensity and duration. However, in some scenarios, the current terrain's permeability must also be considered. This permeability refers to the terrain's water absorption and the speed at which rainwater can penetrate it. Different materials have different permeabilities; for example, dirt has a much higher permeability than concrete. Furthermore, in this embodiment of the application, the cumulative rainfall also needs to consider the terrain of the avatar's location. Specifically, the target parameters can also include terrain information, such as whether the location has a slope or whether it is a depression. This is because, in locations with slopes, the cumulative rainfall will be less than the actual product of rainfall intensity and duration. In depressions, the cumulative rainfall will be greater than the actual product of rainfall intensity and duration. In other words, the current rainfall in this embodiment of the application needs to comprehensively consider various factors to more realistically reproduce real-world rainfall conditions in the game scene, thereby more realistically simulating real-world footsteps and providing users with a more realistic gaming experience.

[0057] In an optional implementation manner in the embodiment of the present application, the method steps in the embodiment of the present application may further include:

[0058] Step 51, determining the game scene according to the current position of the virtual character; and

[0059] Step 52: Select the first footstep sound according to the terrain material of the game scene and / or select the second footstep sound according to the terrain material of the game scene.

[0060] As can be seen, in the implementation of this application, although the first footstep sound refers to the footstep sound produced in a scene without rain, and the second footstep sound refers to the footstep sound produced in a scene with rain, the type of the first footstep sound and the type of the second footstep sound are different depending on the different terrain materials in the game scene. For example, if the terrain material in the current game scene is wooden flooring, the second footstep sound will be different from the second footstep sound in the current game scene if the terrain material is concrete flooring. The footstep sound on wooden flooring is crisper, while the footstep sound on concrete flooring is muffled. The above is just an example. The type of footstep sound corresponding to the specific material in the game scene can be set accordingly with reference to the footstep sound in the real world.

[0061] Corresponding to the above Figure 1 , the embodiment of the present application also provides a device for synthesizing footstep sound effects in a game scene, such as Figure 3 As shown, the device includes:

[0062] an acquisition module 32 for acquiring a current rainfall amount in a game scene, wherein the game scene has a footstep sound effect including a first footstep sound, wherein the first footstep sound is a footstep sound generated in a scene where it is not raining;

[0063] An adding module 34 is configured to add a second footstep to the game scene when the current rainfall exceeds a preset rainfall value, wherein the second footstep sound refers to the footstep sound generated in the rain scene;

[0064] a first adjustment module 36 for adjusting the volume of the first footstep and the volume of the second footstep based on the current rainfall, wherein the volume of the first footstep is negatively correlated with the volume of the second footstep; and

[0065] The synthesis module 38 is configured to synthesize the first footstep sound after the volume is adjusted and the second footstep sound after the volume is adjusted into a current footstep sound effect in the game scene.

[0066] Through the device of the embodiment of the present application, since the game scene includes a footstep sound effect of a first footstep, and when the current rainfall in the game scene exceeds a preset rainfall value, a second footstep will be added to the game scene, and then the volume of the first footstep generated in the rainy scene and the volume of the second footstep generated in the non-rainy scene are adjusted based on the current rainfall, and then the first footstep with adjusted volume and the second footstep with adjusted volume are synthesized into the footstep sound effect in the game scene. Since the volume of the first footstep is negatively correlated with the volume of the second footstep, that is, in the rainy scene, the second footstep will be reduced while the first footstep is increased, or the second footstep will be increased while the first footstep is reduced. In other words, the superposition of footsteps in the game scene of the present application is more in line with the sound auditory effect of rainy footsteps in the real world, thereby solving the problem of poor auditory realism of footsteps in rainy days in game scenes in the prior art.

[0067] Optionally, the first adjustment module 34 in the embodiment of the present application may further include: a first determination unit, used to determine the rainfall range into which the current rainfall falls; and a first adjustment unit, used to adjust the volume of the first footsteps to a first volume corresponding to the rainfall range based on a mapping relationship, and adjust the volume of the second footsteps to a second volume corresponding to the rainfall range; wherein the mapping relationship is used to characterize the mapping relationship between the rainfall range, the volume of the first footsteps and the volume of the second footsteps; the rainfall range is negatively correlated with the volume of the first footsteps, and the rainfall range is positively correlated with the volume of the second footsteps.

[0069] Optionally, the device in the embodiment of the present application may also include: a second adjustment module, used to increase the low-pass cutoff frequency of the first footsteps while increasing the volume of the first footsteps; and a third adjustment module, used to reduce the low-pass cutoff frequency of the first footsteps while reducing the volume of the first footsteps.
