Short QuakeC movement exhibition on pd_ladders.bsp
The map shown in the video above is pd_ladders.bsp (a test map from progs_dump 3) by dumptruck_ds. Player movement, both acceleration and the slidemove, is all done through custom QuakeC running on the FTEQW engine. Movement techniques shown include ladders (obv.), mantling, stairstepping (airsteps), Q1 air accel, Q3 air accel (strafejumping), CPM air control, and so on.
I wish I could've chosen to obsess over something other than a Quake mod. Having said that the movement feels pretty good now. It's getting there.
