How do I check for a tile in a tilemap: and check around it for other tiles?

I'm not sure if I'm following correctly. Can you elaborate on what specifically you are trying to create?

Also, for deleting the extra sprites you could go through all of them and see which ones is the biggest. Or by the order they were created. Or you delete the previous ones as you go before adding a larger one.

BaconSwagg what im creating is a building system like dungeon keeper. press tile to build a room. simples.

but. i need to know how big a room is. like in dungeon keeper. if a training room is 3x3 it has a rotating spike thing. increasing room efficiency.

same for hatchery. 3x3, it can spawn chickens.

same for graveyard. 3x3 has a grave that can store dead bodies in.

library bookshelf, increasing efficiency.

i tried deleting sprites: on created, is overlapping sprite, choose instance of sprite where sprite width< sprite width : destroy sprite... does nothing...

the aim is just to have 1 sprite covering over all the tiles (THAT ARE CONNECTED)

and.. somehow performs this on another tile with same y and >X... as im ending the loop it wont get there.. setting the search to start from the click i guess.

i also ideally want to use a tilemap, not a sprite, so i can tell exactly how many tiles are in the room. but, ill work on that later. with some words of wisdom from rojohound.

slowly working on it.

sorry its a complicated mess.. i dont get it.. numbs my brain.. hoping someone will see what my aim is
