Sharing is caring: draw triggers area in game.

[Mr H. 400]

Hey guys thought I'd share it with you, it might come in handy when debugging your missions.
 

/*
Function name:MRH_fnc_drawTrigger
Authors: Mr & Mrs H.(she did the maths)
Description: draw triggers in game when the player goes near them, trigger is drawn in red, in green if it's been activated. Statements and other infos are displayed. Useful for debugging missions.
Return value:
Public: Yes
Parameters: None
Example(s):
[] spawn MRH_fnc_drawTrigger;

Good work!

Except perhaps some zero division in case of...  non-area trigger.

[HazJ 1288]

@Mr H.

Are you telling us porkies (lies)?

Did Mrs H do the coding and you did the math?

[pierremgi 4743]

A good idea anyway. keep it up  @Mr H.

[Mr H. 400]

@pierremgiYes I thought about the divisor by zero issue for non area triggers but forgot to fix it, it should be fairly easy.

Great tool!

You could use params to define multiple variables in one line.
