Hi All,

I was in need of a little math help that I can't seem to find the answer to, any links to documentation would be greatly appreciated.

Heres my situation, I have no idea where I am in this maze, but I need to move around and find my way back to the start. I was thinking of implementing a waypoint list of places i've been offset from my start at 0,0. This is a 2D cartesian plane.

I've been given 2 properties, my translation speed from 0-1 and my rotation speed from -1 to 1. -1 is very left and +1 is very right. These are speed and not angles so thats where my problem lies. If I'm given 0 as a translation speed and 0.2 I will continually turn to my right at a slow speed.

How do I figure out the offsets given these 2 variables? I can store it every time I take a 'step'.

I just need to figure out the offsets in x and y terms given the translations and rotation speeds. And the rotation to get to those points.

Any help is appreciated.
