Multiple tilemaps - positiontotile only works on one tilemap

I've got a map with a lot of different tilemaps setup in a 16*16 grid and whenever I try to remove tiles the player collides with it only affects the tilemaps that have X=Y

Here's the basic idea:

Player "On collision w/ Tilemap" > Erase tile at (Tilemap.tiletopositionX(Player.X),Tilemap.tiletopositionY(Player.Y))

Am I missing some way of referencing which tilemap instance the player is currently over using the sprite XY positions?

Are these different tilemap objects, or different instances?

newt It's different instances of the same tilemap object

You must pick them first using variable comparisons, or pick "nth", or some other unique identifier.

You can then reference other tile maps that were not picked using the instance index, Tilemap(0).tiletopositionX(Player.X)

newt Thanks! You've pointed me in the right direction.
