## Console variables
|
||
|
|
|
||
|
|
Console variables (or CVars) are present in all quake-based games.
|
||
|
|
|
||
|
|
By default, it is settings, created by engine, server or client libraries.
|
||
|
|
|
||
|
|
But you can use `set` command to define variables even if they are not created by the engine.
|
||
|
|
|
||
|
|
For example, you can set cvar before it is registered in code.
|
||
|
|
|
||
|
|
`set defaultmap crossfire`
|
||
|
|
|
||
|
|
This works even in server.cfg before server cvars initialization and the engine will reuse its value on cvar creation
|
||
|
|
|
||
|
|
## Aliases
|
||
|
|
|
||
|
|
An alias allows to define new commands.
|
||
|
|
|
||
|
|
`alias wnext "invnext;wait;wait;+attack;wait;-attack"`
|
||
|
|
|
||
|
|
You can hook any command by adding an alias to it and unaliasing it, when you want to use original command.
|
||
|
|
|
||
|
|
```
|
||
|
|
alias invnext1 "unalias invnext;wnext;alias invnext invnext1"
|
||
|
|
alias invnext invnext1
|
||
|
|
```
|
||
|
|
|
||
|
|
## Scripting extensions
|
||
|
|
|
||
|
|
This is an extensions of Xash3D FWGS(merged to original Xash3D since build 3887), that can be enabled by cmd_scripting cvar.
|
||
|
|
|
||
|
|
Enabling scripting: `cmd_scripting 1`
|
||
|
|
|
||
|
|
This is an archive cvar and it will be saved.
|
||
|
|
|
||
|
|
### CVar substitution
|
||
|
|
|
||
|
|
You can substitute cvar value to any command by adding \$ symbol:
|
||
|
|
|
||
|
|
`echo $sv_cheats`
|
||
|
|
|
||
|
|
### Condition checking
|
||
|
|
|
||
|
|
Allows checking cvar values.
|
||
|
|
|
||
|
|
```
|
||
|
|
if <value1> <operator> <value2>
|
||
|
|
:<action1>
|
||
|
|
:if <value3>
|
||
|
|
::<action2>
|
||
|
|
:<action3>
|
||
|
|
else
|
||
|
|
:<action4>
|
||
|
|
```
|
||
|
|
|
||
|
|
* Values are any string or numeric values (for example, substituted cvars).
|
||
|
|
* Operator is = (or ==), \!=, \<, \>, \<=, \>=. == is same to =.
|
||
|
|
* If single value specified, condition is true when value is non-zero
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```
|
||
|
|
if $sv_cheats == 1
|
||
|
|
:echo Cheats enabled, adding cheat menu
|
||
|
|
:exec cheatmenu.cfg
|
||
|
|
else
|
||
|
|
:echo Please enable cheats to use this!
|
||
|
|
```
