[Scenario]

Could you make a loop through all object models and then run this on a 50-100ms interval? Something like this, maybe?

pawn Code:

for(new model = 0; model < sizeof(objectModelArray); model++)
{
    defer removeBuildingsOnInterval(playerid, model);
}
    
timer removeBuildingsOnInterval[100](playerid, model) return RemoveBuildingForPlayer(playerid, model, 0.0, 0.0, 0.0, 9999.9999);
