[Solved] Picking by UID, not knowing which sprite it is

I'm looking to pick a sprite just by UID, not by selecting the sprite first.

Synopsis: I have a platformer which has objects in a room. As I pick up an object, I destroy it and keep track of the UID in an array. These objects differ. Eg: SpriteCoin, SpriteDiamond, SpriteDoor

When I go to another room(layout) I am reading the array and trying to remove the entries with the UID since they were picked up before.

Eg: Picked 3 items in the room. Item stored in Array(room#,Object.UID) as 1

Come back to room.

Loop through XY array

If array(Current Room#, array.YCur) = 1

UIDofSpriteToDestroy = array.Ycur

Destroy Sprite UIDofSpriteToDestroy

In searching the forums/FAQ/tutorials I see several example of picking by UID, but my understanding is that you know what sprite it is.

Can anybody provide insight?

Thanks.

You can do all of this with the Persist behaviour, it will remember what you picked up when you go between rooms : https://www.scirra.com/manual/161/persist

In terms of your actual logic, you can't pick the sprite plugin, only the objecttype.UID so spritecoin.UID, spritediamond.UID. What you could do is put all collectable items into a Family and use Family.IID.

OMG — you are a STAR! I hadn't come across persist, but that it exactly what it needs (per the manual write up too)

Thank you, that is brilliant.
