Emh, i dont remember how ProxDetector works and i don't understand what is your problem. You mean that when a player is inside an interior he can read the whole chat (of all players) and not the local chat and you wanna disable this?

Then...

pawn Код:

if(GetPlayerInterior(playerid)==INTERIOR_ID)
{
//your proxdetector stuff
}

Otherwise, explain better.
