certain areas blanked out for certain players...

I didn't know if this one should go in the JASS category or the trigger category, so I posted it here.

Anyway, my question. I want certain parts of the map blanked out for only certain players. Do I use that JASS command GetLocalPlayer ? or can I do this with triggers?

Any help appreciated.

Doesn't the visibility modifier actions already take the player as a parameter? If that's the case (which I'm pretty sure it is) you don't need any advanced triggering.
