{
InteractConnectPropWithMoveObject("wheeltodoor1", "wheelrust", "GateOpenClose", true, false, 0);

AddEntityCollideCallback("Player", "Gategoeslocked", "CloseGate", true, 1);
SetEntityPlayerInteractCallback("wheelrustthree", "rustwheel", false);
AddEntityCollideCallback("Lever", "Mount" , "LeverMount", true, 1);
SetEntityConnectionStateChangeCallback("LeverComplete", "leverfunc");
}
void CloseGate(string &in asParent, string &in asChild, int asEntity)
{
SetMoveObjectStateExt("GateOpenClose", 0, 8, 16, 0, false);
