Summary0002991: [Edit] Fix GetCVar in A_JumpIf actions
DescriptionThis is a pretty handy ACS function.
It's a part of ZDoom 2.8 but not 2.7.1

Edit: Turns out this does (kind of) exist but crashes the game on startup.
There may also be other ACS functions that also are supposed to work in A_JumpIf but crash instead.
Additional InformationExample of usage
Actor CustomParticle {

            TNT1 A 0 A_JumpIf(GetCVar("vid_renderer") == 0,"Spawn0")
            TNT1 A 0 A_JumpIf(GetCVar("gl_particles_style") == 1,"Spawn1")
            TNT1 A 0 A_JumpIf(GetCVar("gl_particles_style") == 2,"Spawn2")

Ok, this function does exist in ACS, however using directly in A_JumpIf causes the game to crash on startup.

Yeah, this one's pretty cut and dry. No reason that what looks like a very useful, if not essential ACS function from ZDoom should be left out of Zandro.

This ticket is referring to the DECORATE version of GetCVar(), which was added in a much later version of (G)ZDoom than the one Zandronum 3.0 is based off of:https://zdoom.org/Changelog/ebe3f23/files [^]

There are several or more DECORATE expressions such as this one that look and behave like their ACS counterparts, but aren't currently in Zandronum right now.

It's up to the developers to decide whether it's possible to backport an out of order feature like this one right now. For now, since GetCVar() works in ACS, you could have DECORATE call an ACS script that returns the CVar's value.
