Unity3D一个简单的动画混合Demo_unity简单的动画系统demo github

          先说说Unity3D关于动画方便的东西，Animation Mixing （动画混合），什么是动画混合呢？举个简单的例子吧，一个模型现在又3种动作，分别是idle、walk、shoot，在Unity3D中一个Layer只能播放二种动画，shoot动作只影响左肩膀的骨骼，而不会影响腿部的动作，所有这里就可以把shoot和walk进行Mixing。

function Start ()
{

//增加一个动画剪辑片段

//
 animation.AddClip(animation["shoot"].clip, "shootUpperBody");
 animation["shootUpperBody"].AddMixingTransform(transform.Find("mover/gun")); //@parm 路径
 animation["shootUpperBody"].AddMixingTransform(transform.Find("mover/roothandle/spine1"));
//设置动画模式 
 animation.wrapMode = WrapMode.Loop;

 animation["jump"].wrapMode = WrapMode.Clamp;
 animation["shoot"].wrapMode = WrapMode.Clamp;
 animation["shootUpperBody"].wrapMode = WrapMode.Clamp;
 
 // Put idle and run in a lower layer. They will only animate if our action animations are not playing
 animation["idle"].layer = -1;
 animation["run"].layer = -1;
 
 animation.Stop();
}

function Update () {
 if (Mathf.Abs(Input.GetAxis("Vertical")) > 0.1)
 {
  animation.CrossFade("run");
  animation["run"].speed = Mathf.Sign(Input.GetAxis("Vertical"));
 }
 else
  animation.CrossFade("idle");

 if (Input.GetButtonDown ("Jump"))
 {
  animation.CrossFade("jump", 0.3);
 }
  if (Input.GetButtonDown ("Fire1"))
 {
  if (animation["run"].weight > 0.5)
   animation.CrossFadeQueued("shootUpperBody", 0.3, QueueMode.PlayNow);
  else
   animation.CrossFadeQueued("shoot", 0.3, QueueMode.PlayNow);
 }
