Problem understanding touch position

Hi i am having problem understanding that how to rotate the object to position if touch is held, can anyone plz tell me ?

Actually I cant understand in this action

TouchX(0,"",0);TouchY(0,"",0)

What does that (0,’’’’,0) mean?

Hi,
They’re the parameters of the touch.

Its not so far from the answer above
The first “0” is the touch identifier
The double quote ("") is the layer by default you get the double quote which is the base layer.
And the last “0” in the bracket is the camera number.

Thanks a lot for your help.
Thanks guys
