Question
I need some advice. I’m trying to get these inner terrain tiles masked correctly. The ones with the darker blue shaded edge in the screenshot below, marked with bright blue squiqlys of mine.
I’ve tried a thousand different combinations and just cant quite get it right. What I have right now works perfectly (first screenshot) as just a normal layout as you can see. But any advice would be appreciated on how to mask out the inner tilers. Right now using Match Corners & Sides.
Hi!
If I am seeing this correctly, the marked tiles have the shadow of the surrounding walls on them and you want to apply them to your map automatically at the right spot.
If you want to want to use the auto-tiler you will need to add additional rules and info to the algorithm in order to make the right shadow tile appear next to each wall. How exactly to do that I cannot tell you.
Another way to achieve shadows would be to add additional info to each wall tile, say inside the occlusion layer and have some global light source cast shadows inside your map. Here is a tutorial on Youtube for how to achieve this in Godot for a 2D platformer.
