Question

The autotile of tilemap is not respecting the diagonals

I have posted this bug a year ago ( Problem in diagonal TileSet on autotile )

Is this the expeted behavior? Is there something I’m doing wrong?

Hi, this isn’t a bug. Some of the terrain bits you’re drawing are just not in the Match Corners and Sides terrain match mode. There’s only 47 different terrain combinations for that mode (instead of the hundreds of possible combinations for a 3x3 grid). I recommend reading the docs page on how to use autotiling.

Basically, here’s all 47 tiles you can use with Match Corners and Sides.

There are no combinations where a corner bit is on, but a side bit adjacent to the corner bit is off, which is why there’s only 47 of them in the first place.

Thanks for the answer.

I’m reading the docs and I could not find where it says that this 47 combinations covers every possible combination. And could not find where it says that the configurations where the terrain bit is set to -1 should not exist.

Moreover, on the experiment, it puts the diagonal tile there sometimes. It’s not consistent.

Thanks for sending the manual, I’ll definitely read it to see if I’m missing something.

The 47 combinations does not cover every combination, yes. Godot doesn’t have a built-in terrain match mode for that. I don’t know why it puts the tile there sometimes.
