Animation Parameter

【Animation Parameter】

　　Animation Parameters are variables that are defined within the animation system but can also be accessed and assigned values from scripts.

　　Animation Parameters 是Animator Controller中的用户自定义变量，script可以获取和设置其值，其值也可以作为transition转换的条件。配置界面如下：

　　有四种类型的Parameter可选：

　　Parameter可以作为transition的判定条件：

　　script访问parameter的示例如下：

 1 using UnityEngine;
 2 using System.Collections;

 4 
 5 public class AvatarCtrl : MonoBehaviour {
 6 
 7     protected Animator animator;
 8 
 9     public float DirectionDampTime = .25f;
10 
11     void Start () 
12     {
13         animator = GetComponent<Animator>();
14     }
15 
16     void Update () 
17     {
18         if(animator)
19         {
20             //get the current state
21             AnimatorStateInfo stateInfo = animator.GetCurrentAnimatorStateInfo(0);
22 
23             //if we're in "Run" mode, respond to input for jump, and set the Jump parameter accordingly. 
24             if(stateInfo.nameHash == Animator.StringToHash("Base Layer.RunBT"))
25             {
26                 if(Input.GetButton("Fire1")) 
27                     animator.SetBool("Jump", true );
28             }
29             else
30             {
31                 animator.SetBool("Jump", false);                
32             }
33 
34             float h = Input.GetAxis("Horizontal");
35             float v = Input.GetAxis("Vertical");
36 
37             //set event parameters based on user input
38             animator.SetFloat("Speed", h*h+v*v);
39             animator.SetFloat("Direction", h, DirectionDampTime, Time.deltaTime);
40         }        
41     }             
42 }

　　综上所述，Animation Parameter是一个script可写，transition可读的控制变量。
