How would you even do this per vertex? There no vertices here per se, because it’s just pixel tilemaps.

://Will this work correctly with multiple light sources?

Yes, I’m gonna work on that today. I think there will be 2-4 light sources max. From experience I can tell nobody sees the difference beyond that.

Most lights in the game will be either on the wall or on the ceiling. Or natural sunlight. So that’s 3 kinds of lights and z-axis.

GFACE: yes

anyway, the fact that you’re doing this per-pixel rather then through vertex maps is impressive. i suggest that you consider vertex shading as an alternative in certain situations, to save CPU.

also, incredible job with the self-shadowing. that’s the way it should be done, the other way (the quick and dirty and ugly as shit way) is far far inferior.

don’t go overboard with it though. in other words, don’t forget to assign lights different z-axes. lamps aren’t always totally flush to the wall, nor is sunlight always exposing the relief of building surfaces.

looking forward to where this is going. keep up the great work.
