Need help!!! Script...

[flamez3]

Use this:

void OnEnter()
{
void AddUseItemCallback("", "cellkey_1", "celldoor_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("celldoor_1", false, true);
PlaySoundAtEntity("", "unlock_door", "celldoor_1", 0, false);
RemoveItem("cellkey_1");
}

////////////////////////////
// Run when Leaving map
void onleave
{
}

The mistakes were that you used a captiel T in true, you didn't put the other quotation mark on UsedKeyOnDoor in void onEnter. Some other mistakes you made in the rest of the script were missing quotations from RemoveItem("cellkey_1");, you also didn't name your function right.. If that doesn't work post it again.
