[SCRIPT] Fatal Error on this script

[TheGreatCthulhu]

True. Also make sure to go to the line that caused the error and inspect the code yourself
The error comes from an "orphaned" method body (the stuff beteen { and } )
Bellow is your original code - the reason for the error is in red:

---

////////////////////////////
// Run when entering map
void OnStart()
{
AddUseItemCallback("", "BasementKey_1", "mansion_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("mansion_1", false, true);
PlaySoundAtEntity("", "unlock_door", "mansion_1", 0, false);
RemoveItem("BasementKey_1");
}
{
AddUseItemCallback("", "startkey", "cabinet_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("cabinet_1", false, true);
PlaySoundAtEntity("", "unlock_door", "cabinet_1", 0, false);
RemoveItem("startkey");
}

////////////////////////////
// Run when leaving map
void OnLeave()
{
}

---

You have to take the AddUseItemCallback(...) call out of there, and delete the invalid {} block.
