Hello friends i want to know what is the utility of cortex command console and some commands (i didn't find on the internetXD)

if any1 know some post a reply lol

Alright.
1. The console lets you input some Lua commands.
2. You can find such commands in the helpful Lua subforum, specifically this topic.

3. What the hell is up with this "submit for money lololol" thing?

nothing it is just a joke XD

Why in god's name did you double post just to correct yourself?
The edit button is there for a purpose!

Also, check out this wiki page.

So is there a way to reload the client within the command menu? Something like /reloadui or the equivalent? It would make minor tweaks to mods just that much more efficient. I know the game doesn't take all that much time to load anyway, but it would be easier to simply wait for it to refresh the rte and index files within a scenario for the purposes of getting that actor's jet pack just right, or the bullet mass on that gun where you want it.

Not on every map, and perhaps not on any map, but I believe there is a slightly hacky way to do it through the gibbing editor. I believe you can reset Lua scripts through the console, but not sure, and Cortex script as I described above.

If you want to reload something, IncludeFile it in an actor's INI file. Then, reload the actor in the Actor Viewer and the object will reload, too.
To reload Lua scripts, use PresetMan:ReloadAllScripts() in the console. Not that this doesn't seem to work on objects that are copied (so, for instance, placed in a scene). It may work if you try reloading the related copy, though.

Is there a way to enter menu commands through the console? I am trying to run 320x240 resolution and that cuts off the menu, preventing me from starting a skirmish.
