Can't get commands to work.

Hey guys I’m pretty new to Rust and currently running it on a mac (yeah I know). Friend told me to use the Grass.on false command to help with FPS. Only thing is whenever I type in the command nothing happens. Nothing happens for the rest of the commands too.

Try “grass.on FALSE” ensuring FALSE is in all caps. This should also work on other commands.

I pulled this from “The Macintosh RUST Thread” after searching around.
