AnimatorOverrideController

Descripción

Interface to control Animator Override Controller.

Animator Override Controller is used to override Animation Clips from a controller to specialize animations for a given Avatar. Swapping Animator.runtimeAnimatorController with an AnimatorOverrideController based on the same AnimatorController at runtime doesn't reset state machine's current state.

There are three ways to use the Animator Override Controller.
1. Create an Animator Override Controller in the Editor.
2. Change one Animation Clip per frame at runtime (Basic use case).
In this case the indexer operator AnimatorOverrideController.this[string] could be used, but be careful as each call will trigger a reallocation of the animator's clip bindings.

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. Changing many Animation Clips per frame at runtime (Advanced use case).
The AnimatorOverrideController.ApplyOverrides method is well suited for this case as it reduce the number of animator's clips bindings reallocation to only one per call.

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);
        }
    }
}
