"LimitGlobalChatRadius" affects the whole chat. For example, when you say something, it will only send it to everyone who's within 40m radius of the person who spoke.

If you want to make a local chat, that is sent to players within 40m radius, use this:

// Will send a message to everyone who is within 40m radius of you, when using "-message".

I'm not sure if it will compile right away, but you get the idea.
