Quake-style movement physics (+walljumps):
=osgjrE5wPR0
Includes the Q3 style of acceleration and friction which allows circle jumps, etc, continuous jumping which allows strafe jumping / bunny hopping, Q2 style additive jumps which allow ramp jumps, ledge jumps, etc, and QuakeWorld / CPMA style air control with some tweaks to make it a better fit (no air control while strafing, good air control while moving straight forward). Walljumping is very straight forward and also additive, so quick walljumps provide a huge boost.
