Entity Activate/Deactivate?

[Bonehead]

Here's my entire script.

void OnStart()
{
SetEntityPlayerInteractCallback("key_tower_1", "ActivateMonster", true);
AddEntityCollideCallback("Player", "script_slam", "func_slam", true, 1);
SetEntityCallbackFunc("chemical_container_full_1", "OnPickup");
}


void OnEnter()
{

}

void OnLeave()
{
}

void ActivateMonster(string &in item)
{
SetEntityActive("servant_brute_1", true);
AddEnemyPatrolNode("servant_brute_1", "PathNodeArea_13", 0, "");
AddEnemyPatrolNode("servant_brute_1", "PathNodeArea_15", 0, "");
AddEnemyPatrolNode("servant_brute_1", "PathNodeArea_4", 0, "");
AddEnemyPatrolNode("servant_brute_1", "PathNodeArea_10", 0, "");
}

void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("door_2", true, true);
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
GiveSanityDamage(5.0f, true);
}

void OnPickup(string &in asEntity, string &in type)
{
SetEntityActive("armour_nice_complete_8", true);
SetEntityActive("armour_nice_complete_7", true);
SetEntityActive("armour_nice_complete_6", false);
SetEntityActive("armour_nice_complete_5", false);
}
