I dont know why but I couldn't stop having -Z be forward so in the end I had to flip the Z axis for any translation and I probably fucked something up somewhere but I couldn't figure it out and i ran out of patience 🙃
Ok I guess I was assuming XNA and DirectX used the same handedness but apparently XNA is right handed even though DirectX is left handed and I'd like to take this opportunity to ask *what the fuck*
So if I want +Z to be forward I have to flip the axis in the renderer? That's obnoxious. But better than -Z being forward in world space since that would confuse the shit out of players
ok one more before i head to bed just to show that it can do more interesting things than just large rectangles made up of smaller cubes
so @Farbs said something about beveling the edges in my block game and that got me thinking and looking at some old 2D terrain art i did
i'm thinking i may stray from minecraft's aesthetics a bit and use this as a sort of style guide
okay so this may seem a little unorthodox but bear with me here
what if
shell texturing in block game
Can't decide if using shell texturing is a great idea or a stupid idea
i feel like i could soften the terrain significantly through no more than normals along the edges of blocks so i made this mockup in photoshop and i think this could actually work?
corners would still look kinda pointy but ¯\_(ツ)_/¯
if i kind of artfully place the camera to cut out the cornflower blue void surrounding this tiny chunk of terrain on all sides its almost starting to look like a real game :D
trying to add a faux edge bevel through normals and actual lighting equations is proving extremely challenging and i'm starting to give serious thought to manually baking the lighting into the textures
after endless futzing about and tweaking i think i have something that may just be workable for this faux bevel effect i want
(note that there's a "bevel" between adjacent blocks cause i haven't made the effect dependent on the block's neighbors yet)
I dunno I'm just not feeling the actual lighting model. Its not like minecraft exactly has realistic lighting anyway: blocks are lit from two opposite sides!
But the problem with baked lighting is if you have non symmetrical blocks you have to make 4 versions of each face to get all the lighting. Not that that's super onerous
Also if I made something like a lectern that would be a lot of work to do manually for each orientation
On the other hand when I made isometric games I'd have to make two of everything to get the lighting right and I didn't mind that so much so maybe I'm overthinking it
ok i figured out a reasonable way to fudge the normals so i won't have to manually bake lighting. basically what i do is set the normals of the edges so that they point towards where the adjacent faces are pointing (90 degree bend) and then i lerp from the face's lighting factor to the neighbor's lighting factor
that gives me the result on the left. i tried just having regular, actual normals, but it creates artifacts like on the right (its accurate that it shades it like that but it looks bad)
i was worried the corners would look too sharp without modification but honestly the smooth gradient does a great job without blunting the corners
took all day but i've optimized the vertex format for blocks *and* implemented auto-bevelled terrain. shown without textures to make the bevelling clearer
doing a side by side with my style guide i think i'm getting there. i'll probably wanna do some fancier color grading on the lighting though, and i want outlines, but the soft rounded feel of the terrain is definitely there now even though its still all cubes
i've brought back the grass, which is actually an obj model
see i made an engine before and appropriated it for this project. it could load obj models (with normal maps) so at first the blocks in my world were actually loaded from obj models
that's why i had to redo a buncha stuff to add the bevelling, since i had to generate the faces myself
I should probably start linking up chunks before I do much else so I don't wind up having to deal with a ton of "this block's neighbor is in another chunk" situations later
had a silly idea for block outlines using the bevel system. i take the dot product of the vector from the camera to the world position with the normal to determine if the bevel normal is pointing away from the camera, then add an outline based on that. there's some outlines where they don't belong but i can get easily rid of those
... i don't hate it? 🤔
Richard Hendricks@eniko would be nice for those of us with low vision. 🤓
