Chat to variable

[Guest]

Hi all

Is there a way to get basically a \param but for if a user chats, not just if they enter a command?

For example:

Chatting "hi" sets a variable to "hi" OR runs a common event which has "hi" as a \param

I have attempted to make it so you can only chat with "/chat [xyz]", removed the chat messages in server strings and make the event say what you said (this way you can use command params to get this), but the speech bubble above your head still displays

If possible, is there a way to do something like this without using source modifications?

If this is not possible, can someone give me some pointers on where I should start with editing source code?

Thanks
