Question

I Make a simple platformer with Tiles. Now i had the idea that some decoration Tiles, should change random Z Layer. So that the Player walks sometimes Infront and sometimes behind the Grass Tiles.

I know you can grab tiles in the level, but can you select 1 Tile and randomes Z index (for example between 1-5) every time the Tile gets placed.

I hope you can at least understand what i mean haha

But i have no clue on how to make this.
Is this ever possible without tracking down every single Tile.

I think you either have to set one specific tile-type to a fixed z layer (with the paint tool), which has the downside of it always being the same tile, unless you duplicate them. Or you have to use several tilemap layers

That information is stored in the TileSet so you’ll need to create alternative tiles to have different rendering settings.

Another option is doing it at runtime using the TileMapLayer._tile_data_runtime_update() method and modifying the TileData.z_index property. Read the documentation to know how to use this method.
