ZDoom

Glad I could help. c:

Thank you very much, that worked perfectly. It might be lazy, but it prevents me from unintentionally cheating. Much appreciated.

Perhaps try "+set sv_jump 1"?

Does anyone happen to know what I can type into the "extra command line arguments" section of ZDL to automatically disable jumping? For some reason, GZDoom doesn't permanently save the setting when you change it in the gameplay options menu, and it's kind of frustrating to have to keep setting it each time I close and reopen GZDoom.
