Scripted Gas Masks

[CAS_Daniel]

Hi

I'm working on a multiplayer scenario where the squad has to don gas masks once a siren sounds or they'll gradually take damage. I'm using the gasmask identities from Shnapdrossel's Mercenary pack.

So far using my own limited knowledge, i've managed to give a "Don Gas Mask" action menu option to all players, that runs an individual .sqs for each player which sets their identity to "gasmask2". I reckon I can implement an animation (if I can find one suitable) and some sort of sound effect myself.
I've also tried delving into triggered resources to make some sort of overlay with limited success (managed to get binoculars to pop up!  ).

I'm after opinions on the best methods to do the following:

• Create a mask lens overlay to slightly limit peripheral vision, but still have access to the action menu.
• Cause gradual damage to players that haven't donned their respirator.

Thanks!
