Layer Offset may not be working correctly

What you did

Tried to offset a tile layer to make tiles appear 3D using z_layers, add_layer, and layer_offset.

What you expected to happen

Two things:

1. Originally I thought that each subsequent tile layer after the first would be offset by the amount specified in layer_offset, but then I thought ...
2. Wouldn't the layer_offset just offset all layers as it is only a single value on the Tilemap, therefore the whole map would be offset and not individual layers? - is there a way to offset a single layer? Like on the add_layer function?

What actually happened

Nothing was offset.

Additional information

This was tested on an alteration of your Hex Tile Odd Rows example.

The only alterations being that I changed the hex to a 3d one and used just a single chunk.

As well as the below code.

I'm sorry if I'm getting something obviously wrong here, I've tried reading the doc comments on the function calls but I couldn't find any examples in the repo that used layer_offset.

Thanks for any help you might have, you've created an excellent extensible plugin here.

Yeah, once 0.5 hit, lots of stuff was rushed out to get the release in on time. I hadn't made any examples to test all the new features yet. Thanks for filing this.

No problem - just an update that's a little more easier to follow than my custom code above.

I edited the random_dungeon example just to include the call to layer_offset.

Which also doesn't offset any layers.

Thanks for the reply and the great work

I've tried to do some debugging on where the z_offset is used in creating the vertices.

The calculation looks like its working fine, the number of indices is also correct.

Tests done on the hex_tile_odd_rows example.

But it will still only display 1 depth of tiles, not the second offset tiles.

I think this might mean that the issue relates to the chunk_dimensions depth rather than the layer_offset?

[wollyroche]

Did some more testing.

I thought I might have found it as I wasn't adding the z index to the Tile points, which I tried doing.

I was sure this would fix it but it still isn't displaying, but I am getting a warning about a tile being out of bounds - even with enough layers added.

Hmm, thanks for this. I'm quite a bit behind on my game project and it is a requirement for it. I hope to have it resolved shortly.
