Gets a unit's collision size maybe?
Information:
Standalone
Table version
Information:
- ITERATIONS : This determines how many iterations it should use (it uses a binary search, 10 is fine, actually, 5 is fine as well, I don't think you need this to be ultra precise, but if you want, go ahead and have 30 iterations.
- Flavors: It comes in three flavors, I figured some people may not like the idea of doing the iterations so much freaking times when collision size is constant per unit type,
so using gamecache to memorize the values is possible, so one of the alternative versions uses CSSafeCache, while the other one uses Table. Please take note that I am not that sure gamecache is faster than the little 10 iterations this function does.
