Math problem, rotation angle.

2 posts in this topic

Hiya, im working on a project of mine, im trying to get the current angle of my avatar inn a simple game.

But i only have these data available, X, Y cords.

So this is my idea, i store my current cords then move the avatar a litle then compere the new cords with the old, then calculate angle, anyone know if this is possible?

Yes. The question is now, how well do you know trigonometry?

The way I'd do this is to construct a small right triangle using the pair of points of the character position to form the hypotenuse. From there, you can fill in a right triangle. Use a little math to solve for certain sides, and arccos, arcsin, or arctan an angle out of it.
