## Functions

### IsCollectibleInItemPool()

`boolean IsCollectibleInItemPool(`[`CollectibleType`](https://wofsauge.github.io/IsaacDocs/rep/enums/CollectibleType.html)`collectibleType,`[`ItemPoolType`](https://wofsauge.github.io/IsaacDocs/rep/enums/ItemPoolType.html) `itemPoolType)`

Helper function to see if the given collectible is still present in the given item pool. If the collectible is non-offensive, any Tainted Losts will be temporarily changed to Isaac and then changed back. (This is because Tainted Lost is not able to retrieve non-offensive collectibles from item pools). Under the hood, this function works by using the ItemPool.AddRoomBlacklist method to blacklist every collectible except for the one provided.
