1. Basic properties

 Scene View Commands

（1）SHIFT+CTRL：add a waypoint Add a track point
（2）SHIFT+ALT：remove a waypoint Remove a track point

INfo

（1）Path Length： Track length

Tween Options

（1）AutoPlay： Auto play
（2）AutoKill： Automatically destroy the animation after playing
（3）Duration： Animation duration
        SpeedBased：If selected ,the duration will count as units/degreex second; If selected , This time is taken as the unit time .

（4）Delay： Time delay
（5）Ease： This is an enumeration , It can be understood as the animation playback rate curve

（6）Loops： cycles , The number of animation cycles
-1： Express Cycle all the time
0： Means to play only once
When it's worth >1 when , The inspector panel appears LoopType, As the name suggests, it refers to the loop type ：
Restart： restart , Later animation cycle playback will restart from the starting point ;
Yoyo： Play back and forth
Incremental： To increase the , hinder path The mobile animation will be played based on the end of the previous cycle

（7）ID： Animation ID
（8）UpdateType： This enumeration has three values , Refers to the update type
Normal： Normal update ,Update()
Late： Update later ,LateUpdate()
Fixed： Fixed update ,FixedUpdate()

Path Tween Options

（1）Path Type： Track line type
Linear： Linear
Catmull Rom： curve
（2）Close Path： Closed curves , Connect the start point and the end point
（3）Lock Rotation： Lock rotation ,xyzw

Path Editor Options： Track editing parameters , No introduction

ResetPath： Reset track
Events：

（1）OnStart： At the beginning of the
（2）OnPlay： When the play
（3）OnUpdate： update
（4）OnStep： When completed in one step
（5）OnComplete： When finished
（6）OnCreated： When creating animation
The sequence of events is ：OnCreated->OnStart->OnPlay->OnUpdate（ Has been performed , Until completion ）, Execute when the animation is completed in one step OnStep, Execute after the whole animation OnComplete

WayPoints： Moving trajectory points

The one on the right Copy to clipboard, Copy coordinates to clipboard

The plus / minus button means to increase or decrease coordinate points

DOLocalPath

2.DoTween Pro Medium motion trajectory （DoTween Path） How to become relative motion

1. When declaring a type, you must declare the type DOTweenPath（ Do not use Tween）, because DORestart It can only be used for DOTweenPath and DOTweenAnimation.
2. Generally, the trajectory is fixed . however —— Here is a but , If you Restart after , It will be based on its current location , Regenerate path , This solves the problem we mentioned above
3. The trajectory is the world coordinate , stay unity Checked in the editor （relative） relative motion , Only valid in the editor ？

3. Code dynamically adds points

	public Vector3[] vector3s;
    public Transform[] targets;
    public Transform earth;
    private void Awake()
    {
        for (int i = 0; i < targets.Length; i++)
        {
            vector3s[i] = new Vector3(targets[i].position.x, targets[i].position.y, targets[i].position.z);
        }
    }
    private void Start()
    {
        earth.DOPath(vector3s, 50, PathType.Linear).SetEase(Ease.Linear).SetLoops(-1);
    }
