The thing is even when my object hits a perfectly flat surface - it still shows a slight discrepancy - it shows every collision no matter where in fact.
Anyway, I cobbled this code together - it's a recursive call which takes an incoming position and velocity, and tries to work out all collisions. From looking at it it seems to work - catching small tight corners etc. It also doesn't make use of my manual calculations, but uses ReflectRay entirely. (I've left in the debug code which compares my mypos error though)
If you spot any errors in this - I'd be grateful to learn, thank you.
