As a warden, I was just wondering how to do these few things:
1. Place/remove multiple markers and change their colors
2. Draw that rainbow line to lead t's
3. Give people "ST" by aiming at them with your crosshair
To place a marker you right click then press 1-4 on your keyboard to select a color.
To draw a line you first have to type !paint to select a color (you only have to do this once unless you want to change the color oh the line) then you just hold your use key to paint
To give st while aiming at them you type out !st AIM. Most people who play warden have a bind for the command and that is what lets them do it so fast.
