I am new to unity3d. I have already used cocos2d-x,libgdx like game engines.Is Unity provide action to run on ui elements like scaleup,scaledown,fadein,fadeout,moveby,moveto etc.Please help if anyone know about it.
It sounds to me like you're looking for a tweening library such as DOTween. Of course such a library doesn't do anything you couldn't do yourself. But it's already written, and maintained by somebody else, which is often a big benefit.
