Unity（三十九）：非运行状态下脚本播放动画、Animator Override Controller、RuntimeAnimatorController

非运行状态下脚本播放动画

• 脚本

  using UnityEngine;
  
  namespace Example_01.Scripts
  {
        
        
  	[RequireComponent(typeof(Animator))]
  	public class PlayAnim : MonoBehaviour
  	{
        
        
  	}
  }
  

  // Editor
  using System.Linq;
  using Example_01.Scripts;
  using UnityEditor;
  using UnityEditor.Animations;
  using UnityEngine;
  
  namespace Example_01.Editor
  {
        
        
  	[CustomEditor(typeof(PlayAnim))]
  	public class PlayAnimEditor : UnityEditor.Editor
  	{
        
        
  		private AnimationClip[] _animationClips;
  		private PlayAnim _script;
  
  		private void OnEnable()
  		{
        
        
  			_script = target as PlayAnim;
  			Animator animator = _script!.gameObject.GetComponent<Animator>();
  			
  			// 控制动画器的 AnimatorController 的运行时表示
  			AnimatorController animatorController = (AnimatorController)animator.runtimeAnimatorController;
  			// 获取动画列表
  			_animationClips = animatorController.animationClips;
  		}
  		
  		// 当前选择的动画下标
  		private int _selectedIndex;
  		
  		// 当前滚动的位置值
  		private float _sliderValue;
  
  		public override void OnInspectorGUI()
  		{
        
        
  			base.OnInspectorGUI();
  
  			// 启动代码块以检查GUI更改
  			EditorGUI.BeginChangeCheck();
  
  			// 获取动画名称列表
  			string[] displayedOptions = _animationClips.Select(clip => clip.name).ToArray();
  			_selectedIndex = EditorGUILayout.Popup("动画", _selectedIndex, displayedOptions);
  
  			// 滑动条
  			_sliderValue = EditorGUILayout.Slider("进度", _sliderValue, 0.0f, 1.0f);
  
  			// 如果发生更改，结束代码块并更新标签
  			if (EditorGUI.EndChangeCheck())
  			{
        
        
  				// 当前使用的动画
  				AnimationClip animationClip = _animationClips[_selectedIndex];
  				// 将总时间均匀分布在滚动条上
  				float time = animationClip.length * _sliderValue;
  				// 在给定时间针对任何动画属性对动画进行采样
  				animationClip.SampleAnimation(_script.gameObject, time);
  			}
  		}
  	}
  }
  

Animator Override Controller

可复用动画控制器，为不同的模型附上相同的动画效果使用

RuntimeAnimatorController

读取/删除 动画控制器

• 脚本

  using UnityEngine;
  
  namespace Example_01.Scripts
  {
        
        
  	public class SetAnim : MonoBehaviour
  	{
        
        
  		public Animator animator;
  		
  		private void OnGUI()
  		{
        
        
  			if (GUILayout.Button("读取控制器"))
  			{
        
        
  				RuntimeAnimatorController controller = Resources.Load<RuntimeAnimatorController>("Animator Controller");
  				animator.runtimeAnimatorController = controller;
  			}
  
  			if (GUILayout.Button("删除控制器"))
  			{
        
        
  				animator.runtimeAnimatorController = null;
  			}
  		}
  	}
  }
