Custom Properties and Background Transparency

Hello, new to game dev here,
I was wondering if it would be possible to specify collision via setting a custom property like: “collision: true” and have the game engine calculate the collision opposed to having to make a separate layer for collision or is a collision layer mandatory?

Secondly is there a way to change the background when loading tilesets with transparency? Or at least a way to leave it the checkerboard background? Something like this

Keep up the great work on tiled!

Tiled provides multiple ways in which you could specify your collision. If you want to set a “collision: true” property on colliding tiles, you can do so by right-clicking on the tile in the tileset, choosing “Tile Properties…” and adding this “collision” custom property using the “+” button in the Properties view. See Custom Properties.

Not right now, though I will certainly add this for Tiled 1.0. There’s an issue about this on GitHub:

I see. Thank you very much bjorn! Keep up the great work.
