[SCRIPT] How to make monster open door?

[The chaser]

It's just that you use a wrong function. Try this:

void BruteOpenDoor_4(string &in asParent, string &in asChild, int alState)
{
AddPropForce("Door", 0, 0, 0, "world"); ////The zeroes are values, experiment with them.
////OR
SetSwingDoorClosed("Door", false, true);
}

SetMoveObjectState is for movable objects (shelfs or secret doors)
