篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了U3D多点触控框架实例（下）相关的知识，希望对你有一定的参考价值。
1.概述
上次我们一口气讲到下层组件讲多点触控的消息根据具体的需求，在每个时刻将其抽象画成单一指令。
接下来我们要聊聊，上层组件中如何将单一的指令应用在角色上，让角色在移动，普通攻击和释放技能中间做出正确的行为。
上次我们也说过了，上层组件是个优先级队列，队列中分别有对移动，普通攻击，技能释放的判定检测组件，按照 技能> 普攻 > 移动的优先级，对下层组件传递过来的消息依次，逐个进行处理。
按照这种设计思路，我们首先还是应该有一个接口，统一组建的操作，然后在响应事件的时候对组件for循环处理
2.队列组件接口
public enum TouchEventType
{
down,
press,
up,
moveEnd,
}
public class ManualControllerCom
{
protected Units self;//绑定的角色
bool pause = true;
protected Units lastTarget;//选定的地方目标
public virtual void OnInit()
{
}
public virtual void OnStart()
{
}
public virtual void OnExit()
{
}
public virtual void OnStop()
{
}
public virtual void OnDown(TriggerParamTouch param)//响应按下事件
{
}
public virtual void OnPress(TriggerParamTouch param)//响应长按
{
}
public virtual void OnUp(TriggerParamTouch param)//响应弹起
{
}
public virtual void OnMoveEnd(TriggerParamTouch param)//响应移动结束，这个消息是别人加的，暂时忽略，
{
}
public virtual void OnSkill(ITriggerDoActionParam param)//点击UI按下
{
}
public virtual void OnNavigateEnd()//寻路结束，也就是寻路到目标位置了
{
}
protected float GetSkillRange(Skill skill)//获取技能攻击范围（其他人添加，不应该放在基类中）
{
if (skill.IsAttack)
{
return self.GetAttackRange(null);
}
else
{
return skill.distance;
}
}
protected Units GetSkillTarget(Skill skill, Units enemyTarget)//获取技能目标<span style="font-family: Arial, Helvetica, sans-serif;">（其他人添加，不应该放在基类中）</span>
{
if (skill.needTarget)
{
if (enemyTarget == null)
{
if (skill.data.targetCamp == SkillTargetCamp.Self)
{
return self;
}
else if (skill.data.targetCamp == SkillTargetCamp.Partener)
{
return self;
}
else if (skill.data.targetCamp == SkillTargetCamp.AllWhitOutPartener)
{
return self;
}
}
else
{
if (skill.data.targetCamp == SkillTargetCamp.Self)
{
return self;
}
else if (skill.data.targetCamp == SkillTargetCamp.Partener)
{
if (enemyTarget.teamType == self.teamType)
{
return enemyTarget;
}
else
{
return self;
}
}
else if (skill.data.targetCamp == SkillTargetCamp.AllWhitOutPartener)
{
if (enemyTarget.teamType == self.teamType)
return self;
else
return enemyTarget;
}
}
return enemyTarget;
}
return null;
}
}该接口响应触控事件，以及技能释放事件
3.上层组件
上层组件主要是集合所有上层操作组件（释放技能，普攻，移动）。

}4.组件实现
a.技能组件
每个组件不仅处理事件，而且会保存角色移动，释放技能，普通攻击的状态。以释放技能为例，其实也有很多状态，可以考虑用状态机，不过有点复杂。技能显示范围指示，技能释放过程中，技能释放结束，技能释放结束的结果，是成功，失败，还是打断，这些状态下，都可能收到对应的消息，那么要对其进行处理。如果不处理，那么信号量就是闲置，接下来普攻组件和移动组件会处理。如果处理了，后面的组件优先级较低，就不会再处理了。由于这个功能完成之后没有及时做笔记，被其他人改的面目全非，所以现在仅仅保留一个影子，可以看到一个大概。
