AnimatorOverrideController

描述

用于控制动画器重写控制器的接口。

动画器重写控制器的用途是重写某个控制器的动画剪辑，从而为给定化身定制动画。 在运行时基于相同的 AnimatorController 交换 Animator.runtimeAnimatorController 和 AnimatorOverrideController 不会重置状态机的当前状态。

可以通过以下三种方法使用动画器重写控制器。\ **1.在 Editor 中创建动画器重写控制器。**\ **2.在运行时每帧更改一个动画剪辑（基本用例）。**\ 在这种情况下，可以使用索引器运算符 AnimatorOverrideController.this[string]，但要小心，因为每次调用都会触发动画器剪辑绑定的重新分配。

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.在运行时每帧更改诸多动画剪辑（高级用例）。**\ AnimatorOverrideController.ApplyOverrides 方法非常适合这种情况，因为它能够将动画器剪辑绑定重新分配的数量减少到每次调用只有一个。

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);
        }
    }
}
