Godot-particles-collision (2D)
what is it particle collision shader for Godot
variants:
v1 simple SDF collision(no loops), SDF created from Polygons2D once(on start), collision by normals generated form SDF. Video youtube link. Only for "static map".
v2 bad normals to edges youtube link. Support collision to dynamic maps/objects.(no need sdf)
v3 will be for Godot4 only, using Vulkan and compute, I do not want make another "bad" physics base on GLES2/3 limitations.
