Splatter floats mid-air

[chrysn]

When bouncing near the edge of a tile, the splatter decal is also painted over the hole in the ground.

(Observed in the version published as 1.0.5 on f-droid, not sure how that's related to the tagged versions in the repository.)

Currently I'm using a plane with a texture, but I have some ideas to solve it, some of them require migrating to godot 3.1 (something I will do any way)

• Use proper decals, something like this: https://godotengine.org/asset-library/asset/241
• Use boolean operations to cut the mesh
• Use a fixed size texture over a mesh created using the platforms borders info.

I think it's something with low priority though.

not sure how that's related to the tagged versions in the repository.

I have also no idea. Gonna use the android version number from now on.

There is a very elegant and computationally simple solution, but it may not be doable on Godot (or any abstraction over OpenGL for that matter): Render the splatter after the lower (but before the upper) platform, render it a bit inside the platform to avoid Z fighting, and invert the Z buffer semantics for this render (so it only renders stuff normally occluded). Thus, you don't have to calculate boolean operations. (OpenCGAL uses this technique for great speedups in CAD).

Sure -- it's a detail that doesn't affect gameplay.
