Where can I find good documentation for UI tool kit .
Like right now I want to get a button to do somthing …

//JumpB is a UI button 
// Ky is anouther script i'm accessing with a public void of Jumpie 
	void Update()
	{
		
		if(JumpB.onTouchBegan== true) {
			Ky.Jumpie();
		}

I thought the developer stop supporting this product already. Although, I think you can still find the tutorial on Youtube, if my memory serves.

I figured out a way to do this , here for all who need it

JumpB is a button , and Ky.Jumpie is a script + the function i’m calling in said script .

void Update(){
JumpB.onTouchUpInside += ( sender ) => Ky.Jumpie();
}
