AnimatorOverrideController

描述

控制动画覆盖控制器的接口。

动画覆盖控制器用于覆盖来自控制器的动画片段，以针对给定化身专门化动画。在运行时，用基于相同AnimatorController的AnimatorOverrideController替换Animator.runtimeAnimatorController不会重置状态机的当前状态。

有三种方法可以使用动画覆盖控制器。
1. 在编辑器中创建动画覆盖控制器。
2. 在运行时每帧更改一个动画片段（基本用例）。
在这种情况下，可以使用索引运算符AnimatorOverrideController.this[string]，但请注意，每次调用都会触发动画师片段绑定的重新分配。

using UnityEngine;

public class SwapWeapon : MonoBehaviour
{
    public AnimationClip[] weaponAnimationClip;

    protected Animator animator;
    protected AnimatorOverrideController animatorOverrideController;

    protected int weaponIndex;

    public void Start()
    {
        animator = GetComponent<Animator>();
        weaponIndex = 0;

        animatorOverrideController = new AnimatorOverrideController(animator.runtimeAnimatorController);
        animator.runtimeAnimatorController = animatorOverrideController;
    }

    public void Update()
    {
        if (Input.GetButtonDown("NextWeapon"))
        {
            weaponIndex = (weaponIndex + 1) % weaponAnimationClip.Length;
            animatorOverrideController["shot"] = weaponAnimationClip[weaponIndex];
        }
    }
}

3. 在运行时每帧更改多个动画片段（高级用例）。
对于这种情况，AnimatorOverrideController.ApplyOverrides 方法非常适合，因为它将动画师片段绑定重新分配的次数减少到每次调用一次。

using UnityEngine;
using System.Collections.Generic;

public class AnimationClipOverrides : List<KeyValuePair<AnimationClip, AnimationClip>>
{
    public AnimationClipOverrides(int capacity) : base(capacity) {}

    public AnimationClip this[string name]
    {
        get { return this.Find(x => x.Key.name.Equals(name)).Value; }
        set
        {
            int index = this.FindIndex(x => x.Key.name.Equals(name));
            if (index != -1)
                this[index] = new KeyValuePair<AnimationClip, AnimationClip>(this[index].Key, value);
        }
    }
}

public class Weapon
{
    public AnimationClip singleAttack;
    public AnimationClip comboAttack;
    public AnimationClip dashAttack;
    public AnimationClip smashAttack;
}

public class SwapWeapon : MonoBehaviour
{
    public Weapon[] weapons;

    protected Animator animator;
    protected AnimatorOverrideController animatorOverrideController;

    protected int weaponIndex;

    protected AnimationClipOverrides clipOverrides;
    public void Start()
    {
        animator = GetComponent<Animator>();
        weaponIndex = 0;

        animatorOverrideController = new AnimatorOverrideController(animator.runtimeAnimatorController);
        animator.runtimeAnimatorController = animatorOverrideController;

        clipOverrides = new AnimationClipOverrides(animatorOverrideController.overridesCount);
        animatorOverrideController.GetOverrides(clipOverrides);
    }

    public void Update()
    {
        if (Input.GetButtonDown("NextWeapon"))
        {
            weaponIndex = (weaponIndex + 1) % weapons.Length;
            clipOverrides["SingleAttack"] = weapons[weaponIndex].singleAttack;
            clipOverrides["ComboAttack"] = weapons[weaponIndex].comboAttack;
            clipOverrides["DashAttack"] = weapons[weaponIndex].dashAttack;
            clipOverrides["SmashAttack"] = weapons[weaponIndex].smashAttack;
            animatorOverrideController.ApplyOverrides(clipOverrides);
        }
    }
}
