Notes
(0015552) Dusk (developer) 2016-09-01 13:15	The A_JumpIf codepointer is called immediately upon entering a state. So your second example is causing an infinite loop of state jumps within the same tic. Of course it's going to crash.

(0015555) Filystea (reporter) 2016-09-01 17:30	fixed with... XBodyMoving: PLAY W 1 PLAY W 0 A_JumpIf( abs(velx) != 0, "XBodyMoving" ) so it's not a bug. My mistake.
