Actions On Button Press

This script shows how you can execute functions and change dvars for a player when that player presses a certain button while showing him instructions on his screen using the key defined in his game.

• The first button lets the player toggle the camera_thirdPerson dvar (used to play in third person while keeping the crosshair on and is also better/more configurable than cg_thirdPerson in my opinion) Note that camera_thirdPerson is a special case and needs to be changed with SetDynamicDvar() but in most cases like with cg_thirdPerson you'd use SetDvar() instead.

• The second button lets the player suicide using the Suicide() function.

If you use +melee and the player's melee key is set to V it'll show V on his screen, if he uses another key it'll show his key.
If you want to use another button simply change level.third_person_button and/or level.suicide_button values and it will update the button pressed to start the function and the text displayed on the player's screen.
