I need some help. I've spent about the last 5 days slowly moving through Tony's vector tutorials, and I can't seem to get past projecting vectors. The whole goal of this is to prepare myself for my all-but-done JIG entry, and yet, maybe it's the way he explains it, but it seems like the concepts don't come across very well at all. The code just seems to be thrown at you, and in the examples, they don't clearly reflect the code displayed in each chapter. Does anyone know of any other vector tutorials that cover the basics of movement and bouncing?
