Make an array of all locations of gambling machines, like I did with vending machines.
pawn Code:
forward IsPlayerNearVendingMachine(playerid);
stock IsPlayerNearVendingMachine(playerid)
{
new Float:machines[][3] =

for(new i = 0; i < sizeof(machines); i++) if(IsPlayerInRangeOfPoint(playerid,2.0,machines[i][0],machines[i][1],machines[i][2])) return 1;
return 0;
}
Then at OnPlayerKeyChange I have this, but I guess you should just flip a variable to 1 or 0.
