Directional Movement with trigonometry

Hey all, This is a relatively simple topic and I have found out how to create an object in OpenGL that moves depending on its current angle using some trig functions, the only problem is that I’m not exactly sure how it works, I know how to use Trigonometric functions for triangles, but I don’t understand how it translates the angle to the right amount of translating, etc. so if anyone can shed some light on this for me it would be greatly appreciated.

Thanks in Advance :slight_smile:
