Scratch

The formula would be this normally

    var __x = _xmouse - this._x ;
    var __y = _ymouse - this._y ;
    var angle = Math.atan2(__y, __x)
 

But this is not possible in scratch because of the lack of the atan2 function.

There is probably a way but I am not a math expert and am not sure how to replace the atan2.

If I were you I would just use the point to block.

No you can't use what I posted. Scratch doesn't have a atan2 function.

How do you make it so that you can point towards a certain coordinate?

Like this:

(only, you'll have to modify this a bit.  It is designed to point away from a sprite)

Where it says "X position of sprite2" use your X coordinate, etc.

atan2 considers quadrants whereas atan does not.

If that doesn't make sense then let me put it this way, with atan you can get angles 0 to 90 with atan2 you can get every angle which is what you need.

atan * 4 = atan2?

DON'T. BUMP. OLD. THREADS.

It's been happening too much lately.
