[Threshold]

For the first one, there should be some codes under OnPlayerCommandText if I am thinking properly, and they should have something like this:

pawn Код:

dcmd(command, 7, cmdtext);

So for example, you would add in:

pawn Код:

dcmd(heal, 4, cmdtext);

EDIT: Oh and I know you are able to get the colors for the medic and taxi driver, but I'm not certain about the SWAT yet.

Medic:
Change text to "~p~Medic"

Taxi Driver:
Change text to "~g~Taxi Driver"
