This is the wiki page for the console command:
The alias command allows the creation of custom console commands that run any combination of commands.
To use the command, open the console and type:
alias double "sv_soccar_gamespeed 2"
This create a new command with the name "double". When calling double via console or keybind, the mod will run "sv_soccar_gamespeed 2".
You can combine multiple commands by separating them with semicolons:
alias double "sv_soccar_boostmodifier 2; sv_freeplay_maxspeed 4600"
Setting a new alias with an already existing name will overwrite the old function of the alias.
Any change of the BakkesMod configuration made through the console is temporary and will be lost when you close Rocket League unless you open and close the GUI once or call the command
