Jump works in the same manner as RandomJump, executing an instant switch to another frame if a randomness test passes. The usage is as follows:

Jump(chance, state)

'chance' is the probability out of 255 that the current frame will be set to 'state'. Note that 'state' cannot refer to global name states (ie. EDF frame mnemonics); this codepointer is strictly for use with DECORATE states.

This codepointer was added in Eternity because RandomJump uses the misc1 and misc2 fields, incompatible with DECORATE. In addition, the A_Jump term is also used in ZDoom's original DECORATE implementation, making the porting of ZDoom DECORATE actors into Eternity quicker. Note that the order of arguments is reversed from RandomJump.
