Description

非玩家角色的控制方法和装置、存储介质及电子设备
本申请要求于2022年09月26日提交中国专利局、申请号为202211174826.0、申请名称为“非玩家角色的控制方法和装置、存储介质及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及计算机技术领域，具体而言，涉及一种非玩家角色的控制方法和装置、存储介质及电子设备。
背景技术
在虚拟游戏场景中，通常会设置多个不同类型的非玩家角色NPC，并并且为了增加游戏的趣味性，会通过NPC的环境感知能力，使得NPC执行指定行为操作，从而实现NPC与玩家之间的交互。
相关技术中，NPC的环境感知能力主要依赖于视觉感知，通常基于NPC和玩家的距离、角度等信息模拟NPC的视觉感知能力，例如，在3D游戏场景中，当玩家位于NPC前方指定距离、指定角度范围内时，NPC会看到玩家，并和玩家进行交互。
然而，相关技术中并未考虑到3D游戏场景对NPC视觉的影响，例如，玩家躲在岩石等障碍物后面时，NPC无法看到玩家，那么当玩家在NPC视野盲区内行走、跑动或冲刺时，NPC将无法感知到玩家，更加无法控制NPC与玩家进行交互，从而造成了无法准确地控制非玩家角色执行行为操作的技术问题。
针对上述的问题，目前尚未提出有效的解决方案。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
首先，对本发明实施例中使用或相关的术语进行如下描述，可以理解的是以下描述是术语的一种解释而不是唯一解释：
AI：游戏中具有拟人化行为的NPC的代称；
听觉范围：AI对象可以听到声音的范围，一般为球形区域；
听觉察觉阈值：引起AI对象察觉的声音强度值，听到大于该值的声音时，AI对象会进入察觉状态；
听觉发现阈值：引起AI对象发现玩家的声音强度值，听到大于该值的声音时，AI对象会发现玩家，和玩家进行交互。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
根据本发明实施例的一个方面，提供了一种非玩家角色的控制方法。作为一种可选的实施方式，上述非玩家角色的控制方法可以但不限于应用于如图1所示的应用场景。在如图1所示的应用场景中，终端设备102可以但不限于通过网络104与服务器106进行通信，服务器106可以但不限于对数据库108执行操作，例如，写数据操作或读数据操作。上述终端设备102可以但不限包括人机交互屏幕、处理器及存储器。上述人机交互屏幕可以但不限于用于显示在终端设备102上的第一玩家角色在第一位置上的运动状态、NPC与第一玩家角色之间的交互行为等。上述处理器可以但不限于用于响应上述人机交互操作，执行对应的操作，或者，生成对应的指令，并将生成的指令发送给服务器106。上述存储器用于存储相关处理数据，如第一声音的第一声音强度、第一声音的第一传播距离及NPC的预设听觉半径等。
作为一种可选的方式，可以在服务器106上执行非玩家角色的控制方法中的以下步骤：步骤S102，获取第一声音的第一声音强度以及第一声音的第一传播距离，其中，第一声音是第一玩家角色在第一位置上产生的声音，第一声音强度是预设的与第一玩家角色在第一位置上的第一运动状态对应的声音强度，第一传播距离是根据第一声音强度确定的传播距离；在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值的情况下，控制NPC执行与第一声音对应的行为操作。步骤S104，在非玩家角色NPC与第一玩家角色之间的第一目标距离小于第一传播距离、且小于NPC的预设听觉半径的情况下，根据第一声音强度以及第一目标距离确定NPC听到的第一声音的声音强度；步骤S106，在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值的情况下，控制NPC执行与第一声音对应的行为操作。
采用上述方式，在根据非玩家角色NPC与第一玩家角色之间的第一目标距离以及NPC的预设听觉半径，确定NPC能够听到第一玩家角色发出的第一声音的情况下，通过比较NPC听到的第一声音的声音强度与第一声音强度阈值，控制NPC执行与第一声音对应的行为操作。换言之，通过比较NPC听到的第一声音的声音强度和第一声音强度阈值，使得NPC能够准确地执行相应的行为操作，避免了无法准确地控制NPC执行行为 操作的技术问题，实现了提高控制NPC执行行为操作的准确性的技术效果。
为了解决上述无法准确地控制NPC执行行为操作的技术问题，本发明实施例提供了一种非玩家角色的控制方法，图2是根据本发明实施例的非玩家角色的控制方法的流程图，该流程包括如下步骤：
步骤S202，获取第一声音的第一声音强度以及第一声音的第一传播距离，其中，第一声音是第一玩家角色在第一位置上产生的声音，第一声音强度是预设的与第一玩家角色在第一位置上的第一运动状态对应的声音强度，第一传播距离是根据第一声音强度确定的传播距离；
示例性的，可以从指定参数值中获取第一声音强度和第一声音的第一传播距离，本申请对此不做限定。例如，可以根据第一玩家角色所处的第一位置，以及在第一位置上的第一运动状态，或者进一步结合其他信息从指定参数值中获取第一声音强度。进一步的，根据第一声音强度可以确定第一传播距离。这里，该第一传播距离可以是虚拟场景中的虚拟距离。
如图3所示，假设第一玩家角色在第一位置上产生第一声音，那么根据第一玩家角色在第一位置上的第一运动状态，即可确定第一声音的第一声音强度。
作为一种可选的示例，如图4所示，当第一玩家角色在第一位置上的运动状态为“行走”时，根据第一玩家角色的运动状态，模拟出在游戏场景中第一玩家角色发出的声音的强度为25DB；当第一玩家角色在第一位置上的运动状态为“潜行”时，根据第一玩家角色的运动状态，模拟出在游戏场景中第一玩家角色发出的声音的强度为10DB；当第一玩家角色在第一位置上的运动状态为“冲刺”时，根据第一玩家角色的运动状态，模拟出在游戏场景中第一玩家角色发出的声音的强度为40DB；当第一玩家角色在第一位置上的运动状态为“飞行”时，根据第一玩家角色的运动状态，模拟出在游戏场景中第一玩家角色发出的声音的强度为20DB。
作为另一种可选的示例，第一声音强度除了与上述第一玩家角色在第一位置上的第一运动状态有关之外，还可以是预设的与第一位置所处的虚拟地形的类型和第一玩家角色在第一位置上的第一运动状态对应的声音强度。其中，对于游戏场景中玩家发出的声音，可以但不限于以玩家的行为状态为基础，模拟出玩家在游戏场景中发出的不同声音的声音强度，例如，如图4所示，当第一玩家位于不同类型的虚拟地形上、且处于不同运动状态的情况下，发出的声音强弱不同。
举例来说，(1)当第一玩家角色在草丛中潜行时，根据第一玩家角色所处的第一位置的虚拟地形“草丛”和运动状态“潜行”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为10DB；根据第一玩家角色所处的第一位置的虚拟地形“地面”和运动状态“潜行”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为15DB；
当第一玩家角色在草丛中冲刺前进时，根据第一玩家角色所处的第一位置的虚拟地形“草丛”和运动状态“冲刺前进”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为40DB；根据第一玩家角色所处的第一位置的虚拟地形“山地”和运动状态“冲刺前进”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为50DB；
当第一玩家角色在地面上正常行走时，根据第一玩家角色所处的第一位置的虚拟地形“地面”和运动状态“行走”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为25DB；根据第一玩家角色所处的第一位置的虚拟地形“草丛”和运动状态“行走”， 可以模拟出在游戏场景中第一玩家角色发出的声音的强度为30DB；
(4)当第一玩家角色在空中飞行时，根据第一玩家角色所处的第一位置的虚拟地形“天空”和运动状态“飞行”，可以模拟出在游戏场景中第一玩家角色发出的声音的强度为20DB。
结合上述分析可知，确定第一声音的第一声音强度的方式可以但不限于根据第一位置的虚拟地形的类型和/或第一运动状态，查询预先创建的关系映射表，即可得到第一声音强度的数值。
步骤S204，在非玩家角色NPC与第一玩家角色之间的第一目标距离小于第一传播距离、且小于NPC的预设听觉半径的情况下，根据第一声音强度以及第一目标距离确定NPC听到的第一声音的声音强度；
容易理解的是，不同类型的NPC，对应的听觉能力也不同，因此，在确定NPC听到的第一声音的声音强度的过程中，除了考虑NPC与第一玩家角色之间的第一目标距离之外，还需要考虑NPC自身的听觉感知能力，例如，NPC的预设听觉半径。
例如，如图5所示，假设第一玩家角色发出的第一声音的传播距离(又可以被理解为第一声音的第一传播距离)为d，第一玩家角色与NPC1之间的目标距离为d1，由于d1>d，NPC1距离第一玩家角色较远，NPC1无法听到第一声音；而第一玩家角色与NPC2之间的目标距离为d2，由于d2<d，且d2<r，确定NPC2可以听到第一声音的声音强度较强，其中，r为NPC2的预设听觉半径，r决定了NPC2的听力范围。进一步地，根据第一声音的第一声音强度及第一目标距离，确定NPC2听到的第一声音的声音强度。
另外，对于NPC1和NPC2是否能够听到第一声音，还可以通过下述实现过程来确定：在第一玩家角色发出第一声音时，首先会根据第一声音的传播距离d，确定处于传播距离d范围内的NPC，如图5所示，包括NPC1和NPC2；然后根据第一声音的声源是否位于NPC的预设听觉半径内，可以确定出仅有NPC2能够听到第一声音。对于NPC1来说，虽然处于第一声音的传播距离d的范围内，但第一声音的声源位于NPC1的预设听觉半径之外，所以NPC1无法听到第一声音。
需要说明的是，上述第一声音的传播距离d、NPC2的预设听觉半径r、NPC1和NPC2与第一玩家角色之间的目标距离等仅为一种示例，并不对其进行限定。
步骤S206，在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值的情况下，控制NPC执行与第一声音对应的行为操作。
通过执行步骤S204，确定NPC听到的第一声音的声音强度的情况下，比较NPC听到的第一声音的声音强度与第一声音强度阈值，例如，比较NPC听到的第一声音的声音强度与NPC的听觉察觉阈值。
显然，容易理解的是，仅在NPC察觉到第一声音的情况下，才可能执行与第一声音对应的行为操作。例如，在图5中所示的NPC2能够听到第一声音，且NPC2听到的第一声音的声音强度大于听觉察觉阈值(第一声音强度阈值)的情况下，执行如图3所示的会话操作。而由于NPC1无法听到第一声音，因此将继续处于日常状态，例如，睡眠、巡逻等。
需要说明的是，上述步骤S202～S206均在服务器侧执行，提高了不同客户端之间数据的同步效率和数据处理效率，避免了客户端作弊、数据同步延迟大等问题。
通过本申请提供的上述实施例，在根据非玩家角色NPC与第一玩家角色之间的第一 目标距离以及NPC的预设听觉半径，确定NPC能够听到第一玩家角色发出的第一声音的情况下，通过比较NPC听到的第一声音的声音强度与第一声音强度阈值，控制NPC执行与第一声音对应的行为操作。换言之，通过比较NPC听到的第一声音的声音强度和第一声音强度阈值，使得NPC能够准确地执行相应的行为操作，避免了无法准确地控制NPC执行行为操作的技术问题，实现了提高控制NPC执行行为操作的准确性的技术效果。
为了确保NPC听觉感知的真实性，使得NPC具有拟人化的听觉感知能力，在本申请实施例中，依据不同参数设置各项规则，来控制NPC执行与第一声音对应的行为操作，例如，NPC的预设听觉半径、第一声音强度阈值等，除此之外，本申请实施例中还提供了第二声音强度阈值。
作为一种可选的示例，上述在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值的情况下，控制NPC执行与第一声音对应的行为操作，包括：
在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值、且小于第二声音强度阈值的情况下，控制NPC执行第一行为操作，其中，第一行为操作是在NPC察觉到有声音时所执行的行为操作。
在本申请实施例中，在NPC能够听到第一声音的情况下，为了准确控制NPC执行与第一声音对应的行为操作，根据NPC察觉到第一声音、但并未发现第一玩家角色，以及NPC察觉到第一声音、且发现第一玩家角色对执行的行为操作进行划分，下面结合具体的示例，先对NPC察觉到第一声音、但并未发现第一玩家角色的情况下，所执行的第一行为操作进行详细描述。
作为一种可选的示例，上述在NPC察觉到第一声音、但并未发现第一玩家角色的情况下，NPC执行与第一声音对应的行为操作，包括：
在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值、且小于第二声音强度阈值的情况下，控制NPC向第一位置移动；或者
在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值、且小于第二声音强度阈值的情况下，控制NPC在向第一位置移动的过程中寻找第一玩家角色。
举例来说，如图6中(a)所示，在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值、且小于第二声音强度阈值的情况下，NPC察觉到了第一声音，并对第一声音引起警觉，并执行察觉行为，例如，向第一玩家角色所在的第一位置S1方向移动。
显然，由于NPC听到的第一声音的声音强度小于第二声音强度阈值，也就意味着NPC只是听到了第一声音，但并未发现第一玩家角色，因此，NPC执行的第一行为操作除了仅向第一位置S1方向移动之外，还可以是边移动边寻找第一玩家角色。
具体地，如图6中(b)所示，在NPC听到的第一声音的声音强度大于或等于第一声音强度阈值、且小于第二声音强度阈值的情况下，NPC向第一玩家角色所在的第一位置S1方向移动，并在移动的过程中寻找第一玩家角色。
作为另一种可选的示例，在NPC察觉到第一声音、且发现第一玩家角色的情况下，上述控制NPC执行与第一声音对应的行为操作，还包括：
在NPC听到的第一声音的声音强度大于或等于第二声音强度阈值的情况下，控制NPC执行第二行为操作，其中，第二行为操作是在NPC发现第一玩家角色时所执行的行为操作。
其中，第二声音强度阈值可以但不限于NPC发现第一玩家角色的听觉发现阈值，也 即，在NPC听到的第一声音的声音强度大于或等于第二声音强度阈值时，NPC将发现第一玩家角色，并执行与第一声音对应的第二行为操作，具体地，包括：
在NPC听到的第一声音的声音强度大于或等于第二声音强度阈值的情况下，控制NPC朝着远离第一玩家角色的方向移动，或者，控制NPC朝着第一玩家角色的方向移动；或者
在NPC听到的第一声音的声音强度大于或等于第二声音强度阈值的情况下，控制NPC与第一玩家角色执行交互操作。
由于在NPC听到的第一声音的声音强度大于或等于第二声音强度阈值的情况下，NPC会直接发现第一玩家角色，并触发NPC对应的发现行为(又可以被理解为第二行为操作)。例如，根据NPC与第一玩家角色之间的关系，控制NPC向远离或靠近第一玩家角色的方向移动，或者控制NPC执行与第一玩家角色之间的交互操作等，下面结合具体的示例对上述发现行为进行描述：
(1)如图7中(a)所示，在NPC发现第一玩家角色的情况下，假设NPC与第一玩家角色处于不同的阵营，或者NPC会对第一玩家角色产生伤害的情况下，则控制NPC远离第一玩家角色；
(2)如图7中(b)所示，在NPC发现第一玩家角色的情况下，假设NPC与第一玩家角色处于同一阵营，或者NPC不会对第一玩家角色产生伤害的情况下，则控制NPC靠近第一玩家角色；
(3)如图7中(c)所示，在NPC发现第一玩家角色的情况下，控制NPC与第一玩家角色执行交互操作，例如，执行对话，或者向第一玩家角色发出提示信息，以告知第一玩家角色NPC的位置或状态等。
通过上述规则，控制NPC执行与第一声音对应的行为操作除了上述第一行为操作和第二行为操作之外，还包括：在NPC听到的所述第一声音的声音强度小于第一声音强度阈值、且小于第二声音强度阈值的情况下，由于NPC并未察觉到第一声音，因此NPC将继续执行日常行为，例如，NPC继续巡逻、休息或睡觉等，具体可参考如图7中(d)所示的示意图。
基于上述各实施例的分析可知，根据上述NPC听到的第一声音的声音强度、第一声音强度阈值和第二声音强度阈值等多个参数，控制NPC执行与第一声音对应的第一行为操作、第二行为操作或日常行为操作等，避免了相关技术中当NPC处于视野盲区时，无法利用NPC的视觉感知能力，拟人化地听到声音的问题，提高了玩家的游戏体验感。
作为一种可选的示例，上述根据第一声音强度以及第一目标距离确定NPC听到的第一声音的声音强度，包括：
根据第一声音强度以及第一目标距离，确定第一声音传播到NPC所在的位置时的剩余声音强度；
获取NPC所在的位置上的环境噪声的声音强度；
根据剩余声音强度和环境噪声的声音强度，确定NPC听到的第一声音的声音强度。
为了确保声源模拟的真实性，需要充分考虑当声音在介质中传播时，声音的强度会随着距离的增加而不断衰减，并且声音的衰减情况与衰减公式和距离、介质特征等因素相关。例如，如图8中(a)所示，从声源处发出的第一声音的声音强度会随着传播距离的增大逐渐衰减至0。
示例性地，假设在本申请实施例中，按照线性衰减公式来模拟声音衰减的具体过程，例如，y＝a/x，其中，y为NPC接收到的第一声音的剩余声音强度，x为第一玩家角色与NPC之间的第一目标距离，a为第一玩家角色在第一位置发出的第一声音的第一声音强度，通过公式可知，随着第一玩家角色与NPC之间的第一目标距离逐渐增大，NPC接收到的第一声音的剩余声音强度逐渐减小，具体地，可参考如图8中(b)所示的示意图。
举例来说，如果8中(c)所示，按照上述线性衰减公式，在玩家角色移动时发出第一声音的情况下，距离玩家角色较近的NPC1(角色等级为Lv.7)接收到的第一声音的剩余声音强度大于距离玩家角色较远的NPC2(角色等级为Lv.6)接收到的第一声音的剩余声音强度，例如，NPC1可以听到玩家角色发出的第一声音，并前来与玩家角色进行交互；而NPC2则仍处于日常状态，例如，执行休息或睡觉等日常行为等。
通过利用上述线性衰减公式，充分考虑了声音传播过程中声音强度跟随传播距离而变化的过程，较为真实地还原了3D虚拟游戏场景中声音的产生、传播等情况。
显然，容易理解的是，上述线性衰减公式仅为一种示例，并不对其进行限定，例如，还可以是其他非线性的衰减公式。
在确定NPC听到的第一声音的声音强度时，除了考虑上述第一声音的衰减过程，还需要考虑环境噪声的声音强度对NPC的听觉感知能力的影响，并在确定NPC所在的位置上的环境噪声的声音强度的情况下，根据NPC所在位置上接收到的第一声音的剩余声音强度和环境噪声的声音强度，确定NPC听到的第一声音的声音强度。
作为一种可选的实现方式，上述根据剩余声音强度和环境噪声的声音强度，确定NPC听到的第一声音的声音强度，包括：
在剩余声音强度大于环境噪声的声音强度的情况下，将NPC听到的第一声音的声音强度确定为等于剩余声音强度与环境噪声的声音强度之间的差值；和/或
在剩余声音强度小于或等于环境噪声的声音强度的情况下，将NPC听到的第一声音的声音强度确定为等于环境噪声的声音强度或者为0。
由于玩家角色发出的第一声音是NPC希望接收到的声音，而周围环境发出的环境噪声则是干扰到NPC听到玩家角色发出的第一声音的声音，因此，在剩余声音强度大于环境噪声的声音强度的情况下，将剩余声音强度与环境噪声的声音强度之间的差值确定为NPC听到的第一声音的声音强度。
需要说明的是，在第一玩家角色发出第一声音，且NPC接收到第一声音的情况下，根据NPC所处位置的XYZ坐标，可以快速定位到NPC所处位置对应如图9所示的目标网格，然后通过查询每个网格对应的环境噪声的声音强度，可以便捷地获取目标网格中的环境噪声的声音强度，提高了获取NPC所处位置的环境噪声的声音强度的效率。
在剩余声音强度小于NPC所处位置的环境噪声的声音强度的情况下，由于NPC接收到的第一声音被NPC所处位置的环境噪声所掩盖，因此，NPC听到的第一声音的声音强度等于NPC所处位置的环境噪声的声音强度。
在剩余声音强度等于NPC所处位置的环境噪声的声音强度的情况下，按照上述剩余声音强度与环境噪声的声音强度之间的差值计算方法可知，NPC听到的第一声音的声音强度为0，也即，NPC实际上并未听到声音。
采用上述方式，根据第一声音传播到NPC所在的位置时的剩余声音强度和NPC所处位置的环境噪声的声音强度，可以准确地确定NPC听到的第一声音的声音强度，提高 了NPC听到的第一声音的声音强度的准确性，同时也有助于准确地控制NPC执行与第一声音对应的行为操作。
作为一种可选的示例，上述获取NPC所在的位置上的环境噪声的声音强度，包括：
确定目标游戏场景中NPC所在的目标网格，其中，目标游戏场景预先被划分成一组网格，一组网格包括目标网格，一组网格中的每个网格预先设置了对应的环境噪声的声音强度，每个网格对应的环境噪声的声音强度是根据每个网格中的虚拟地形的类型确定得到的声音强度；
将NPC所在的位置上的环境噪声的声音强度确定为等于预先设置的目标网格对应的环境噪声的声音强度。
在获取NPC所在的位置上的环境噪声的声音强度之前，需要对整个游戏场景进行网格化划分，例如，根据实际的游戏画面，将整个游戏场景划分为2D的正方形网格，或者划分为3D的正方体网格。在本申请实施例中，假设将整个3D游戏画面划分为如图9所示的一组0.5m*0.5m*0.5m的正方体网格。
利用上述网格化划分后的游戏场景，确定NPC所在的位置上的环境噪声的声音强度的具体实现步骤，包括：
S1，设置目标游戏场景中每个网格的环境噪声的声音强度；
显然，容易理解的是，在实际生活场景中，身处森林时的环境噪声的声音强度大于身处草地时的环境噪声的声音强度，而处于瀑布周围的环境噪声的声音强度又大于身处森林时的环境噪声的声音强度。也即，每个网格中的虚拟地形的类型直接影响着该网格的环境噪声的声音强度。
因此，在本申请实施例中，建立了一套从虚拟地形到环境噪声的声音强度的模拟系统，即，根据每个网格中的虚拟地形的类型，可以确定每个网格对应的环境噪声的声音强度。
如图10所示，当NPC所处的虚拟地形为森林时，对应的环境噪声的声音强度预先设置为10DB；当NPC所处的虚拟地形为草地时，对应的环境噪声的声音强度预先设置为0DB；当NPC所处的虚拟地形为瀑布时，对应的环境噪声的声音强度预先设置为20DB。
在本申请实施例中，通过预先计算出这个游戏场景中各个网格的环境噪声的声音强度，减少了环境噪声的声音强度的查询时间，提高了确定每个网格对应的环境噪声的声音强度的效率，提升了服务器的数据处理效率。
S2，确定目标游戏场景中NPC所在的目标网格；
例如，当NPC所在的位置完全处于1个网格中的情况下，直接将该网格确定为NPC所在的目标网格；当NPC所在的位置处于2个或2个以上网格中的情况下，将多个网格中NPC位置占比最大的网格确定为目标网格。
S3，将预先设置的目标网格对应的环境噪声的声音强度确定为NPC所在位置上的环境噪声的声音强度。
如上所述，噪声作为声音的一种，也可以在介质中传播，并且也存在衰减的情形。对于每个网格对应的环境噪声的声音强度，除了受到该网格自身虚拟地形的影响之外，还受到周围网格中的虚拟地形的影响。因此，在本申请实施例中，也采用线性衰减的模拟形式，确定每个网格对应的环境噪声的声音强度。
作为一种可选的示例，在考虑周围网格中的虚拟地形的情况下，确定每个网格对应 的环境噪声的声音强度的实现方式如下：
对一组网格中的每个网格执行以下操作，得到每个网格对应的环境噪声的声音强度，其中，在执行以下操作时，每个网格为当前网格：
获取当前网格对应的初始噪声的声音强度，其中，初始噪声的声音强度与当前网格中的虚拟地形的类型具有预设的对应关系；
获取当前网格收到的传播噪声的声音强度，其中，传播噪声的声音强度包括一组网格中除当前网格之外的每个网格对应的初始噪声传播到当前网格时的剩余声音强度；
根据初始噪声的声音强度和传播噪声的声音强度，确定当前网格对应的环境噪声的声音强度。
如图11所示，假设一组网格中共包括2个网格，假设1#网格为当前网格，那么，确定当前网格对应的环境噪声的声音强度的具体步骤如下：
S11，首先根据每个网格中的虚拟地形模拟出每个网格对应的初始噪声的声音强度；
例如，1#网格的初始噪声的声音强度为10、2#网格的初始噪声的声音强度为20。
S12，计算每个网格对应的初始噪声在传播过程中对周围网格的噪声影响值；
其中，噪声影响值可以但不限于一组网格中除当前网格之外的每个网格对应的初始噪声传播到当前网格时的剩余声音强度。例如，1#网格对应的初始噪声传播到2#网格时的剩余声音强度为5，2#网格对应的初始噪声传播到1#网格时的剩余声音强度为15，也就意味着，1#网格收到2#网格的传播噪声的声音强度为15，2#网格收到1#网格的传播噪声的声音强度为5。其中，在上述各个步骤中，声音强度的计量单位可以但不限于分贝(DB)
需要说明的是，在1#网格对应的初始噪声向2#网格传播的过程中，或者2#网格对应的初始噪声向1#网格传播的过程中，均存在声音强度的衰减。
S13，根据1#网格对应的初始噪声的声音强度和1#网格收到的传播噪声的声音强度，确定1#网格对应的环境噪声的声音强度。
采用与上述步骤S11～S13相同的方法，在将2#网格确定为当前网格的情况下，也可以根据2#网格对应的初始噪声的声音强度和2#网格收到的传播噪声的声音强度，确定2#网格对应的环境噪声的声音强度。
作为一种可选的示例，上述根据初始噪声的声音强度和传播噪声的声音强度，确定当前网格对应的环境噪声的声音强度，包括：
将当前网格对应的环境噪声的声音强度确定为等于初始噪声的声音强度和传播噪声的声音强度中的最大声音强度；或者
将当前网格对应的环境噪声的声音强度确定为等于初始噪声的声音强度和传播噪声的声音强度之和；或者
将当前网格对应的环境噪声的声音强度确定为等于对初始噪声的声音强度和传播噪声的声音强度进行加权求和所得到的值。
下面结合具体的示例，对上述当前网格对应的环境噪声的声音强度的具体实现方法进行介绍。
(一)对于当前网格对应的环境噪声的声音强度确定为等于初始噪声的声音强度和传播噪声的声音强度中的最大声音强度的情况；
如图11所示，在1#网格为当前网格的情况下，假设1#网格的初始噪声的声音强度为10、1#网格收到的传播噪声的声音强度为15，那么取10和15中的最大值，作为1# 网格最终的环境噪声的声音强度，也即，1#网格对应的环境噪声的声音强度为15。
在2#网格为当前网格的情况下，假设2#网格的初始噪声的声音强度为20、2#网格收到的传播噪声的声音强度为5，那么取20和5中的最大值，作为2#网格最终的环境噪声的声音强度，也即，2#网格对应的环境噪声的声音强度为20。
(二)对于将当前网格对应的环境噪声的声音强度确定为等于初始噪声的声音强度和传播噪声的声音强度之和的情况；
如图12所示，假设一组网格中共包括9个网格，且1#～9#网格对应的初始噪声的声音强度分别为V1、V2...V9，以当前网格为5#网格为例进行说明。
由于5#网格周围包括1#～4#、6#～9#网格，假设1#～4#网格各自对应的初始噪声传播到5#网格时的剩余声音强度分别为V'1～V'4，6#～9#网格各自对应的初始噪声传播到5#网格时的剩余声音强度分别为V'6～V'9。那么，5#网格对应的环境噪声的声音强度为V＝V5+V'1...V'4+V'6+V'9。
需要说明的是，采用上述线性衰减的模拟形式，在上述1#～4#、6#～9#网格对应的初始噪声传播到5#网格时，各个初始噪声的声音强度可能衰减至0。也即，5#网格收到的传播噪声的声音强度V'1～V'4、V'6～V'9中可能部分取值为0。
(三)对于将当前网格对应的环境噪声的声音强度确定为等于对初始噪声的声音强度和传播噪声的声音强度进行加权求和所得到的值的情况；
仍以图12为例，根据1#～4#、6#～9#网格对应的初始噪声的类型，或者1#～4#、6#～9#网格与5#网格之间的距离远近，对5#网格收到的传播噪声的声音强度分别设置不同的权重。例如，距离5#网格较近的周围网格的传播噪声的声音强度所占的权重较大，距离5#网格较远的周围网格的传播噪声的声音强度所占的权重较小。
对5#网格的初始噪声的声音强度V5和传播噪声的声音强度V'1～V'4、V'6～V'9进行加权求和，得到5#网格对应的环境噪声的声音强度为V＝W1V5+W2V'1...W5V'4+W6V'6...W9V'9。
通过上述方式，在考虑NPC所在位置的虚拟地形的前提下，通过引入NPC所在的目标网格对应的初始噪声的声音强度及目标网格接收到的传播噪声的声音强度，充分考虑了环境噪声的衰减和周围网格的环境噪声对目标网格对应的环境噪声的声音强度的影响，提高了环境噪声的真实性。
作为一种可选的示例，上述方法还包括：
根据NPC的角色类型设置预设听觉半径，其中，当NPC的角色类型为听力灵敏的角色类型时，预设听觉半径被设置为第一值，当NPC的角色类型为非听力灵敏的角色类型时，预设听觉半径被设置为第二值，第一值大于第二值；或者
根据NPC的当前状态设置预设听觉半径，其中，当NPC的当前状态为未受到攻击伤害的状态时，预设听觉半径被设置为第一值，当NPC的当前状态为受到攻击伤害的状态时，预设听觉半径被设置为第二值，第一值大于第二值；或者
根据NPC的目标技能的释放状态设置预设听觉半径，其中，目标技能用于在被释放的状态下增加NPC的听觉范围，当目标技能的释放状态为已释放状态时，预设听觉半径被设置为第一值，当目标技能的释放状态为未释放状态时，预设听觉半径被设置为第二值，第一值大于第二值。
结合上述实施例的描述可知，NPC的预设听觉半径表示NPC自身的听觉感知能力， 也可以被理解为NPC可以接收到声音的听力范围。因此，在判断NPC能否能到第一玩家角色发出的第一声音的过程中，预设听觉半径的设置起着至关重要的作用，下面结合的示例对如何设置NPC的预设听觉半径进行描述。
第一种：假设根据NPC的角色类型，将NPC划分为听力灵敏和非听力灵敏两种不同的类型；
在与第一玩家角色之间的距离相同情况下，听力灵敏的NPC听到的第一声音的声音强度大于非听力灵敏的NPC听到的第一声音的声音强度。或者，听力灵敏的NPC能够听到第一玩家角色发出的第一声音，但非听力灵敏的NPC不能听到第一声音，也即，听力灵敏的NPC的预设听觉半径大于非听力灵敏的NPC的预设听觉半径。
如图13中(a)所示，在将听力灵敏的NPC的预设听觉半径设置为第一值r1、将非听力灵敏的NPC的预设听觉半径设置为第二值r2时，r1>r2。
第二种：假设根据NPC的状态特征，将NPC划分为受到攻击和未受到攻击两种不同的类型；
显然，容易理解的是，在与第一玩家角色之间的距离相同情况下，受到攻击的NPC听到的第一声音的声音强度小于未受到攻击的NPC听到的第一声音的声音强度。或者，未受到攻击的NPC能够听到第一玩家角色发出的第一声音，但受到攻击的NPC不能听到第一声音，也即，未受到攻击的NPC的预设听觉半径大于受到攻击的NPC的预设听觉半径。
如图13中(b)所示，在将未受到攻击的NPC的预设听觉半径设置为第一值r3、将受到攻击的NPC的预设听觉半径设置为第二值r4时，r3>r4。
第三种：假设根据NPC的技能释放状态，将NPC划分为技能未释放和技能已释放两种不同的类型。
在与第一玩家角色之间的距离相同情况下，技能未释放的NPC听到的第一声音的声音强度大于技能已释放的NPC听到的第一声音的声音强度。或者，技能未释放的NPC能够听到第一玩家角色发出的第一声音，但技能已释放的NPC不能听到第一声音，也即，技能未释放的NPC的预设听觉半径大于技能已释放的NPC的预设听觉半径。
如图13中(c)所示，在将技能未释放的NPC的预设听觉半径设置为第一值r5、将技能已释放的NPC的预设听觉半径设置为第二值r6时，r5>r6。
通过上述方式，根据NPC的角色类型、NPC的当前状态及NPC的目标技能的释放状态，设置不同类型后处于不同状态下的NPC的预设听觉半径，提高了设置预设听觉半径的灵活性，提升了预设听觉半径的真实性。
作为一种可选的示例，根据上述NPC的预设听觉半径、第一声音强度阈值和第二声音强度阈值等参数，可以控制NPC执行与第一声音对应的第一行为操作、第二行为操作。除此之外，通过第一声音强度阈值和第二声音强度阈值，还可以控制NPC的行为操作进行切换，具体地，包括：
在控制NPC执行与第一声音对应的行为操作的过程中，获取第二声音的第二声音强度以及第二声音的第二传播距离，其中，第二声音是第二玩家角色在第二位置上产生的声音，第二声音强度是预设的与第二玩家角色在第二位置上的第二运动状态对应的声音强度，第二传播距离是根据第二声音强度确定的传播距离；
在NPC与第二玩家角色之间的第二目标距离小于第二传播距离、且小于NPC的预 设听觉半径的情况下，根据第二声音强度以及第二目标距离确定NPC听到的第二声音的声音强度；
在NPC听到的第二声音的声音强度大于或等于第一声音强度阈值、且大于NPC听到的第一声音的声音强度的情况下，控制NPC停止执行与第一声音对应的行为操作，并控制NPC执行与第二声音对应的行为操作。
其中，第二声音强度与第二传播距离的获取方式与第一声音强度以及第一传播距离类似，可以参考上文中的描述。
如图14中(a)所示，假设NPC正在执行与第一玩家角色P1发出的一声音对应的行为操作，例如，靠近第一玩家角色P1。位于第二位置S2上的第二玩家角色P2发出第二声音，根据第二玩家角色P2在第二位置S2上的第二运动状态对应的声音强度，获取P2在S2上的第二运动状态对应的第二声音强度V2。具体过程可以参考上述实施例中对第一玩家角色在第一位置上的第一运动状态对应的第一声音强度部分的描述，此处不再赘述。
其中，第二玩家角色P2在第二位置S2上的第二运动状态包括但不限于如图4所示的潜行、冲刺、行走和飞行等。
在NPC与第二玩家角色之间的第二目标距离小于第二传播距离、且小于NPC的预设听觉半径的情况下，确定NPC能够听到第二玩家角色发出的第二声音，此时，根据第二声音强度V2以及第二目标距离，确定NPC听到的第二声音的声音强度。
如果NPC听到的第二声音的声音强度大于或等于第一声音强度阈值、且大于NPC听到的第一声音的声音强度，也就意味着，NPC已经察觉到了第二声音，并且NPC听到的第二声音干扰到了NPC预先听到的第一声音。那么NPC将停止靠近第一玩家角色P1，并执行与第二声音对应的行为操作，例如，如图14中(b)所示的远离第二玩家角色P1。
可见，在NPC听到第一玩家角色和第二玩家角色发出的第一声音和第二声音的情况下，分别计算第一声音和第二声音的声音强度，在确定NPC听到的第二声音的声音强度大于NPC听到的第一声音的声音强度的情况下，切换NPC执行的行为操作，提高了NPC所执行的行为操作灵活性，丰富了游戏的玩法，提升了用户体验感。
为了更加清晰地理解上述非玩家角色的控制方法，下面结合如图15所示的整体流程图对其进行进一步描述，具体地，包括：
S1502，计算环境噪声的声音强度；
例如，通过如图9～图12所示的示意图，将目标游戏场景预先划分成一组网格，并根据一组网格中的每个网格中的虚拟地形的类型确定每个网格对应的环境噪声的声音强度，确定每个网格的环境噪声的声音强度可以参考上述实施例部分的描述，此处不再赘述。
S1504，模拟玩家角色发出的第一声音的声音强度；
假设玩家角色在游戏场景中的第一位置上产生第一声音，那么根据玩家角色在第一位置上的运动状态，即可模拟出玩家角色的第一声音的声音强度。
其中，第一声音的声音强度与第一位置所处的虚拟地形的类型和/或玩家角色的运动状态之间的关系，可以但不限于通过查询预先创建的关系映射表来确定。
S1506，通过第一声音的传播距离和NPC的预设听觉半径，筛选出NPC；
作为一种可选的示例，通过图5所示的第一声音的传播距离d和NPC的预设听觉半 径来筛选NPC，具体实现过程如下：
如图5所示，假设第一玩家角色发出的第一声音的传播距离(又可以被理解为第一声音的第一传播距离)为d，第一玩家角色与NPC1之间的目标距离为d1，由于d1>d，NPC1距离第一玩家角色较远，NPC1无法听到第一声音；而第一玩家角色与NPC2之间的目标距离为d2，由于d2<d，且d2<r，确定NPC2可以听到第一声音，其中，r为NPC2的预设听觉半径，r决定了NPC2的听力范围。
另外，对于NPC1和NPC2是否能够听到第一声音，还可以通过下述实现过程来确定：在第一玩家角色发出第一声音时，首先会根据第一声音的传播距离d，确定处于传播距离d范围内的NPC，如图5所示，包括NPC1和NPC2；然后根据第一声音的声源是否位于NPC的预设听觉半径内，可以确定出仅有NPC2能够听到第一声音。对于NPC1来说，虽然处于第一声音的传播距离d的范围内，但第一声音的声源位于NPC1的预设听觉半径之外，所以NPC1无法听到第一声音。
通过上述方式筛选出的NPC与第一玩家角色之间的目标距离小于第一声音的传播距离、且小于NPC的预设听觉半径。
进一步地，通过采用上述方式对NPC进行筛选，仅需要对满足要求的部分NPC执行后续的计算，其中，后续的计算包括但不限于NPC收到的第一声音的剩余声音强度的计算、NPC实际听到的第一声音的声音强度的计算等。
例如，假设虚拟场景中NPC的总数量为100个，按照上述筛选方法，确定只有2个NPC满足要求，那么，只需要计算2个NPC收到的第一声音的剩余声音强度和实际听到的第一声音的声音强度，实现了减少计算量、提高NPC执行行为操作的效率的技术效果。
S1508，计算第一声音传播至第一位置时，NPC收到的第一声音的剩余声音强度；
为了确保声源模拟的真实性，需要充分考虑当声音在介质中传播时，声音的强度会随着距离的增加而不断衰减，并且声音的衰减情况与衰减公式和距离、介质特征等因素相关。例如，如图8中(a)所示，从声源处发出的第一声音的声音强度会随着传播距离的增大逐渐衰减至0。
其中，在本申请实施例中，可以但不限于按照线性衰减公式来模拟声音衰减的具体过程，例如，y＝a/x，其中，y为NPC接收到的第一声音的剩余声音强度，x为第一玩家角色与NPC之间的第一目标距离，a为第一玩家角色在第一位置发出的第一声音的第一声音强度。
S1510，查询环境噪声的声音强度；
首先对整个游戏场景进行网格化划分为一组网格，并预先为一组网格中的每个网格设置对应的环境噪声的声音强度，最后根据每个网格中的虚拟地形的类型确定NPC得到的声音强度。
做为一种可选的示例，可以直接将NPC所在位置上的环境噪声的声音强度直接确定为预先设置的目标网格对应的环境噪声的声音强度，或者根据查询到的目标网格对应的初始噪声和周围网格产生的初始噪声传播至目标网格后的剩余声音强度，确定目标网格对应的环境噪声的声音强度，具体过程可以参考上述实施例部分的描述。
S1512，计算NPC实际听到的第一声音的声音强度；
示例性地，在第一声音传播到NPC所在位置时的剩余声音强度大于环境噪声的声音强度的情况下，将NPC听到的所述第一声音的声音强度确定为等于剩余声音强度与环境 噪声的声音强度之间的差值；或者
在剩余声音强度小于或等于环境噪声的声音强度的情况下，将NPC听到的第一声音的声音强度确定为等于环境噪声的声音强度或者为0。
S1514，比较NPC听到的第一声音的声音强度与听觉察觉阈值、听觉发现阈值之间的关系，并执行响应的行为操作，如步骤S1516；
例如，在NPC听到的第一声音的声音强度大于或等于听觉察觉阈值(第一声音强度阈值)的情况下，执行上述实施例中的第一行为操作，例如，寻找玩家。
在NPC听到的第一声音的声音强度大于或等于听觉发现阈值(第二声音强度阈值)的情况下，控制所述NPC执行第二行为操作，例如，会话或与玩家互动。
S1516，控制NPC执行与第一声音对应的行为操作。
通过本申请提供的上述实施例，在根据非玩家角色NPC与第一玩家角色之间的第一目标距离以及NPC的预设听觉半径，确定NPC能够听到第一玩家角色发出的第一声音的情况下，通过比较NPC听到的第一声音的声音强度与第一声音强度阈值，控制NPC执行与第一声音对应的行为操作。换言之，通过比较NPC听到的第一声音的声音强度和第一声音强度阈值，使得NPC能够准确地执行相应的行为操作，避免了无法准确地控制NPC执行行为操作的技术问题，实现了提高控制NPC执行行为操作的准确性的技术效果。
