I've made a point to mouse script using trigonometry but it only works if the mouse pointer is in the top lest part of the screen since both the X and Y positions are positive there.
Is it possible to make the arrow point to the mouse anywhere?

The problem here is that Scratch doesn't have an ATAN2 function block.
But, here is a hint to help you:

It keeps one sprite pointed away from another. But, if you're smart enough, you should be able to get the info you need out of the drawing.
