Unity3D一個簡單的動畫混合Demo

          先說說Unity3D關於動畫方便的東西，Animation Mixing （動畫混合），什麼是動畫混合呢？舉個簡單的例子吧，一個模型現在又3種動作，分別是idle、walk、shoot，在Unity3D中一個Layer只能播放二種動畫，shoot動作隻影響左肩膀的骨骼，而不會影響腿部的動作，所有這裡就可以把shoot和walk進行Mixing。

 

function Start ()
{

//增加一個動畫剪輯片段

//
 animation.AddClip(animation["shoot"].clip, "shootUpperBody");
 animation["shootUpperBody"].AddMixingTransform(transform.Find("mover/gun"));
//@parm 路徑
 animation["shootUpperBody"].AddMixingTransform(transform.Find("mover/roothandle/spine1"));
//設定動畫模式 
 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);
 }
