行为树中需要的参数可以来自游戏中的各个模块如果仅需从多个模块获取少量参数那么可以直接在代码中调用其他模块的单例继而层层调用获取数据。
如果获取的参数量很大从架构上看我们需要通过加一个中间者去管理各个模块的参数获取调用行为树从中间者获取数据即可。
换一种说法就是要有共享数据的地方通常会采用黑板模式。
综合来说存在以下情况
多个不同的动作节点或条件节点需要获取或设置来自不同模块的属性多个不同的动作节点或条件节点会获取或设置相同模块的同一属性不同动作节点之间有通信A动作节点生成的临时数据是B动作节点所需的数据不同动作节点存在大量重复计算例如距离计算多个动作节点会共用临时存在的多个数据
针对这些情况我们可以通过键值对的形式实现黑板模式
需要注意的是这些黑板不属于节点考虑到不同行为树也会共享数据因此也不一定属于黑板。需要有一个黑板的管理者来做数据管理。
黑板模式的数据管理本质还是通过键值对的方式为处理不同的情况我们需要对每种情况提供不同的Key。这和MVC中的数据管理并无本质区别。
和节点参数配置不同的是这里是要程序做控制的而且不确定性更大无法做明确的规定。
在这种情况下我们需要对每个数据做单独得ID定义每个数据有各自的获取设置方法通过ID映射。
根据行为树ID节点ID数据ID方法ID可以实现不同的数据获取程序只需实现方法ID即可。
在黑板中我们需要根据这些参数生成唯一的Key这里自然而然的就会需要对参数做封装用泛型用对象池。
同样的我们需要有这些参数对应的结果考虑数据类型差异结果有效性等自然也需要做封装。
【动作节点的实现位置】
在整个游戏中与角色相关的模块如下
角色动画基于状态机提供动作切换提供最基础的接口角色运动包括基础移动走、跑等地形移动蹲下、跳跃、攀爬等寻路。会调用角色动画提供的接口角色交互 与物体的交互拾取、推开、握住、抓住、攀绕、踢开等等。会调用角色动画或角色运动提供的接口前者为主与角色的交互主要是打击、少量握手、拥抱等。会调用角色动画或角色运动提供的接口前者为主角色技能技能、Buff、伤害计算、效果表现。会调用角色动画或角色运动或角色交互提供的接口前者为主角色属性记录角色的各类状态角色行为这里就是角色AI会调用角色动画或角色运动或角色交互或角色技能或角色属性提供的接口
因此在实现动作节点时属于其他模块的直接调用其他模块的接口或在其他模块内实现属于角色行为的在动作节点内实现。
例如就技能而言对角色技能来说不同角色的技能各有差异要做不同的实现但对角色AI而言只有普攻、技能、技能、大招等
