How do you set bullet angle of motion to imagepoint

I have seen in the suggestions for angle of motion that you can set a bullets angle of motion to a image point but i run into problems whit expressions. What expression should i use in order for it to work?

I'm not sure what you mean..

An image point doesn't have an angle it's just a point..

If you mean setting the origin of a sprite to another position so it rotates around that point, it's as simple as changing the position of the origin in the image editor..

This is what i mean. Understand any better?

Sorry, I still don't understand what you are trying to do..

an angle is meassured in degrees (between 0 and 360) and you want to use the x-coordinate of an imagepoint for that?

Could it be you are trying to set an angle towards an imagepoint or from an imagepoint to somewhere else?

If I understand correctly...

angle(x1, y1, x2, y2) Calculate angle between two points

System expressions
