IndexOutOfRangeException in TileMap grid

I’ve got an IndexOutOfRangeException by painting some tiles:

[Edit] Error:   An error occurred: IndexOutOfRangeException: Index was outside the bounds of the array.

Got it! The bug wasn’t actually related to the repro steps, but occured when click-dragging the fill tool across a tilemap border, i.e. starting an operation on a valid tile and holding the mouse button while moving the cursor so it would hover a tile out of range.

Fixed, binary package update on its way. Should be available in about 10 minutes.

I think an message-dialoge would be nice. Its going to pop up when you didn’t save your work and ask you, if you want to apply your changes.

I checked on this again, and the message dialog actually does pop up - but only when you attempt to close the Tileset editor or deselect the Tileset. As long as you keep it open and don’t select a different Resource, you won’t get the dialog.

Experimented with showing it when tabbing the editor away in addition to closing it, but that turned out to be too annoying to make it the regular behavior. Tabbing away an active editor is something that does happen in regular workflows a lot - without necessarily meaning that the previous operation needs to be applied.

End result: I’m going to leave the dialog behavior as is for now.

I could reproduce this bug by doing this:

1. Import spritesheet into the project view
2. create a spritesheet from the imported pixmap -> set tile size (16x16)
3. open tile editor -> set tile size (16x16) for the tileset (main texture)
4. “setup tilemap layers” -> single layer
5. selected a empty tile from the tile palette and filled the whole map with this empty tile (color bucket)

I just realized that I forgot to hit that “Apply”-Button in the Tileset-Editor… So thats seems to be bring on the bug.

I can’t reproduce the bug here using the steps and regardless of whether or not I hit Apply. Are you reproducing the bug in a new, empty project? Can you go into more detail what exactly you’re doing, i.e. “what buttons you’re pressing in which order”? Also, can you upload the .png file of the tileset you’re using?
