There's a number of things wrong with that.
First of all, Slayer_MinigameHandlerSO::addMinigame(%this, %client, %configFile) does not even take a BLID.
Secondly, how will the server know which bricks, vehicles, etc. belong to which minigame? When a minigame resets, it will end up resetting things that other minigames are using.
There's a bunch more problems but I'm not going to go into detail. I appreciate your enthusiasm to help, but you should probably remove this.
