LeanTween Class

Defined in: LeanTween.cs:203

LeanTween is an efficient tweening engine for Unity3d

Index of All Methods | Optional Paramaters that can be passed

Optional Parameters are passed at the end of every method

Example:
LeanTween.moveX( gameObject, 1f, 1f).setEase( LeanTweenType.easeInQuad ).setDelay(1f);

You can pass the optional parameters in any order, and chain on as many as you wish!

You can also modify this tween later, just save the unique id of the tween.

Example:

int id = LeanTween.moveX(gameObject, 1f, 1f).id;
LTDescr d = LeanTween.descr( id );

if(d!=null){ // if the tween has already finished it will return null
   // change some parameters
   d.setOnComplete( onCompleteFunc ).setEase( LeanTweenType.easeInOutBack );
}

)

Defined in LeanTween.cs:1153
