Metadata for autolayer rules

[TheNeikos]

I'm using the autolayer feature to create 'grass decorations': , and I'd like to render them above the player. But since they share the same tileid as the actual 'solid' grass I cannot differentiate between them. I could see multiple ways this might be helped:

• A flag 'toFront/toBack' or so. This is not so ideal, as it presumes that the editor is only ever used for sidescrollers etc.. but that's not true IIUC
• Custom data that can be set project-wide similar to entites, where a autolayer 'group'/rule has to pick a value from it. In my case I'd make it an enum with 'Background/Solid/Foreground' depending on what I'd need it to do.
• Custom data per autolayer group/tile, every group/tile can have the same or different values.

I'd also be willing to help implement this if you accept pull-requests!

The current way to do that is to create a separate AutoLayer (a pure one, not an IntGrid) that uses the IntGrid where collisions are. This separate layer can hold any "front" object easily.

Then, in your game, just render the layer above player.

There is a demo of this in the Typical 2d platformer sample:

bg_textures uses collisions as source for its data.

Ah! That works like a charm! I guess that covers my use case then. I didn't know you could apply autolayers from other intlayers. Thanks!
