A_CustomPunch cannot set flags in Zandronum without crashing

Execution could not continue.

2 errors while parsing DECORATE scripts

 

The script error in question:

 

Normal:
    KNFS G 1 A_CustomPunch(2, CPF_NOTURN)
    Goto FireEnd
Berserked:
    KNFS G 1 A_CustomPunch(20, CPF_NOTURN)

 

The PK3 was originally designed for GZDoom, thought it was good idea to port to Zandronum for multiplayer compatibility, turns out Zandronum's system is vastly different from GZDoom's.

 

I still want my knife to not jerk sideways when stabbing someone, so please provide a workaround.

Found out the solution. THIS is the acceptable script lol.

A_CustomPunch(2, "false", "CPF_NOTURN")
