1. Add animation
Select the object to be animated, under the Animation window
Notice: If the selected object does not have an Animation/Animator component, the Animator component will be added automatically.
2. Animation

Preview: Enable/disable scene preview mode.
Recording: Enable/disable keyframe recording mode.

Go to the previous keyframe.
Play animation clip.
Go to next keyframe.

2.2 The produced Animation animation
| Length | Length (animation duration) |
|---|---|
| Loop Time | cycle |
| Loop Pose | Loop action (make the head and tail connection smooth when looping) |
| Cycle Offset | Smoothness |
2.3 Adding and using events
public class AnimEvents : MonoBehaviour
{
private void Start()
{
// 创建一个事件
AnimationEvent evt = new AnimationEvent();
// 绑定触发事件后要执行的方法名
evt.functionName = "PrintEvent";
// 执行方法后要传入的参数
evt.intParameter = 12345;
// 设置事件关键帧的位置，当事件过了1.3秒后执行
evt.time = 0.5f;
// 设置目标动画剪辑
AnimationClip clip = this.GetComponent<Animator>().runtimeAnimatorController.animationClips[0];
// 绑定事件
clip.AddEvent(evt);
}
private void TestAniEvent(string param)
{
Debug.Log("事件触发，参数是：" + param);
}
private void PrintEvent(int param)
{
Debug.Log(param);
}
}
==Note:==The script and the object where the animator is located are in the same object
3. Animator
3.1 Production interface
3.2 Explanation of some parameters
- Solo and Mute
When an animation has multiple subsequent animations:
After the animation is played, the front (or top) state transition in the action list is given priority.
Solo: When a certain Transition is set to Solo, the mark is given priority. Solo's animation transfer
Mute: selected state transfer is disabled - ** Has Exit Time **
Whether there is an exit time. Simple understanding: turning on means waiting for the current animation to finish before proceeding to the next animation; turning off means interrupting the current animation immediately and playing the next animation.
3.3 Animation parameters
Code control:
public class AnimControl : MonoBehaviour
{
private Animator anim;
private void Start()
{
anim = this.GetComponent<Animator>();
}
private void Update()
{
if (Input.GetKeyDown(KeyCode.R))
{
anim.SetBool("BoolParams", true);
}
if (Input.GetKeyDown(KeyCode.S))
{
anim.SetBool("BoolParams", false);
}
}
}

5. Animation playback and pause control
1. Animotor
// 播放
animator.Play("ani_name");
// 暂停
animator.speed = 0;
// 继续播放
animator.speed = 1;
// 重置到起始帧
animator.Play("ani_name", 0, 0f);
2. Animation
// 播放
animition.Play("ani_name");
// 暂停
animition["ani_name"].speed = 0;
// 继续播放
animition["ani_name"].speed = 1;
// 重置到起始帧
public void ResetAni(Animation ani, string name)
{
AnimationState state = ani[name];
ani.Play(name);
state.time = 0;
ani.Sample();
state.enabled = false;
