What do CVAR do?

[Leather Realms]

I don't really get how this code works exactly. I was messing around Doom Shinobi and Third Person.wad and I realized that these mods use CVAR for Chase Camera. I think this is how they made it default camera mode instead of toggling it from First Person to Chase Camera.

CVAR just stands for "Console Variable." It's a way to store (and set) the engine settings. Usually, there will be a menu provided to change these, but sometimes, there isn't and you have to set them via the console.

It's unlikely the WADs you mention "use" CVARs "for" the chance camera. Rather, the variable is used to set that option.

What do you mean it is unlikely for them to use CVARs for the chase camera?

I mean that chase-cam behavior is either defined in-engine, or scripted using ZScript or something like that (if the WAD includes some non-standard camera behavior).

 

The CVAR is (most likely) just used to toggle the effect on/of, and maybe adjust some options, but most runtime variables should not be exposed to the end-user.

 

 

To give an example with a different concept: player speed, ammo count, and monster health are are variables, but they're not console variables. Autorun on/of is a CVAR, and it has an effect on player speed, but it doesn't control it.

How come I can't toggle on/off Chase Camera when I played Doom Shinobi?
I don't get it.

set cvar

dmflags2 2097152

if that doesn't work, idk what will - I don't use GZDoom

I don't get it then, why are you telling me this code if you don't use GZDoom?

I think Horizon is just pretty much saying that they can't guarantee it'll work. Or perhaps it is something much more nefarious.

Doom Shinobi has its own chase camera implementation that doesn't read GZDoom's built-in "chase" toggle, probably because GZDoom's chase camera is pretty bare-bones and doesn't let you do things like have the camera face a different direction than the player. Though it still uses chase_dist as the setting for how far away the camera should be.

OHHH so, they made their own chase camera and they made it default. The GZDoom engine read the script and made it in the way Doom Shinobi wanted too. If that's not what you are saying then, I'm still confused. What are we talking about?
