Well, that's an easy one.
The reason why the sabers have much better hit detection vs in JK2 is because the saber collisions were based solely on the saber entity's bbox. Basically, you were swinging around a huge ass box on a stick when it came to saber collisions.
Anyway, I'll keep working on the issue but I seriously don't see a way to improve the collision detection without some increase in CPU useage.
However, on the plus side, the methods I've tried so far result in no preceivable CPU lag and my improved ghoul2 trace code should in theory use less CPU than the original system.
Oh yeah, and it's all open source as part of OJP (
