Tilemap - Bounds (bug?)

Unity Engine
1

Hi, I’m trying to know the current size of a tile map and for that I’ve experimented with “localBounds” and “cellBounds” but their behaviour is a bit weird.

Here’s a video of what’s happening: Dropbox - File Deleted - Simplify your life

The white border is a gizmo drawing the bounds rectangle (“cellBounds” in this case).

Basically it seems that once the bounds grow they never shrink back even if no tile is present.

Any hints?

[EDIT]
I just noticed there’s a “CompressBounds” method that does what I need - removes the empty bounds space. It’s just a bit weird this has to be done manually, but I guess that will have to do.
In the meantime, if someone knows a better way to do this please let me know!

The bounds of the Tilemap represents the largest previously painted area. CompressBounds will compress the bounds to the extents of actual filled Tiles, and is a rather expensive operation so it is not called automatically. CompressBounds can be called from the menu dropdown of the Tilemap inspector (using the gear dropdown button).
