Thanks for your comment. Try this article. It puts all the theory and a bit more, into practice: Android 2d rotation and heading demo. It is for Android in Java but shouldn’t be too hard to translate to your chosen platform.

Good luck!

Another good article. From this post I was able to code a triangle spaceship and make it rotate when I press either the left or right keyboard buttons.

Had a quick question. If I wanted the ship to move around like an asteroids game. How to get the ship to propel forward or backwards based off the angle, also, how do I figure out the angle that it is pointing. If you don’t have an article already about this, would be a good one!

Thanks!
