@andrybak Ah, yes, forgot to mention them, like I usually forget to add them in jam games 😅 Will do, thanks!

@lisyarus@mastodon.gamedev.place avatar lisyarus , to random

Sooo initially the idea was that stone paths and similar floorings make movement faster. Now I've noticed that moving on them is actually slower.

The thing is, I haven't even started implementing this mechanic yet... 🤣

@artificialmind Ohhh wow good catch, I missed that somehow. It worked fine before, guess I broke it at some point. Will investigate, thanks!

Haha I know that feel. I had projects with codenames villages and villages2, and somewhere there's also villages_old xD

> eventually realized that this approach was not suitable for a game: it was too slow, and gave me too little control over the output

I'm starting to feel like this is a common problem with all realistic-simulation-based approaces. E.g. my weather simulation suffers from the same exact problems.

I also probably need to put up a page with some info about my game, while the Steam page isn't up yep. Gonna steal that idea :)

Btw I don't think I've shown my game's terrain LODs earlier, so here they are!

lisyarus OP ,
@lisyarus@mastodon.gamedev.place avatar

@thomastc That's a missing feature in water rendering - a parent chunk overlapping a child chunk. In reality it should only render the quadrants that correspond to children that haven't been loaded yet, working on that right now!

@lisyarus@mastodon.gamedev.place avatar lisyarus , to random

Finished refactoring water rendering to use the same chunk-based LOD system as the terrain, with frustum culling and async loading and stuff. No more missing chunks & holes & flickering, everything works smoothly! 🥰

> carrying a dependency like OpenGL or even Vulkan on a modern Linux system is impossible to do statically

It is possible if you just manually load the libraries at runtime 😈 But yes, in any case it's a dependency on libGL and libX11, even if not on the ELF level

lisyarus ,
@lisyarus@mastodon.gamedev.place avatar

@nelson @c9a @demofox Why cross-libc though? You will end up depending on libc anyway on your program unless you specifically say otherwise, which people usually don't do when targeting regular desktop systems. And yes, I'm just dlopen-ing the libs and dlsym-ing the required functions with a known and documented interface

lisyarus ,
@lisyarus@mastodon.gamedev.place avatar

@nelson @c9a @demofox Well, to get to glxGetProcAddress you still have a ton of X11 window and gl context initialization, which requires a lot of dlsym-ing as well

lisyarus ,
@lisyarus@mastodon.gamedev.place avatar

@nelson @c9a @demofox Honestly it's just the easiest not-stupidly-slow way of getting some pixels on screen that I know of! You still need the X11 window initialization stuff, and then the actual GL code is like 5-10 lines.

My dynamic water system is currently somewhat independent of the large-scale water created at world generation, which leads to some fun stuff like creating a layer of water...underneath existing water 😅

Also decided I'm tired of doing C++ uni lectures based on some older slides & notes by the previous lecturer so I grabbed my shit and made my own slides and I'm happy with how they turned out (but that's just for the first lecture, now I'm forced to re-do the remaining 15 as well)

Implemented the infinite* water plane - the world map now looks cohesive instead of floating in space 🥰 I'll probably want to add something more interesting on the water-horizon boundary (like some clouds, idk), but this will do for now.

@dfxluna I draw a giant square around my map (with a hole where the map itself goes), then apply my usual water shader but with some noise at a distance to make it look more interesting, that's it!

Re-implemented shoreline & distant forest outlines by making them output unique tags to the stencil buffer and then doing a fullscreen outline pass based on that, which now looks much closer to how all the other outlines look 🥰

lisyarus OP ,
@lisyarus@mastodon.gamedev.place avatar

The shader is stupidly simple: count how many of the neighbouring 8 pixels have a different tag compared to current pixel, then the outline strength is smoothstep(0, 4, count), that's it

RE: https://mastodon.gamedev.place/@lisyarus/116047741002986610

I want to redo outlines so that they all use the same mechanism (rn forest outline is baked into mesh, water outline is faked in shader). I can't output some tags to a second render target due to dual-source blending, but I still CAN use stencil for that! Gonna experiment later.

@lisyarus@mastodon.gamedev.place avatar lisyarus , to random

Btw I made the water color (the scattering coefficients, to be precise) depth-dependent, so now shallow seas are more cyan and deep seas are dark-blue. Much better than a flat color!

lisyarus OP ,
@lisyarus@mastodon.gamedev.place avatar

@thomastc Given that Earth does that quite often, I think the trick is already in Public Domain 😆

lisyarus OP ,
@lisyarus@mastodon.gamedev.place avatar

@nick Tbh from this distance it's mostly just a flat color! I'm calling it scattering because I'm multiplying incoming sky light with the coefficient, which is kinda what scattering does.

My model for water shading mostly affects close-up and underwater views. It's a very ad-hoc mix of Fresnel reflection of sky and sun (sun uses blinn-phong), sky light scattering in water volume, and absorption in water volume. I'm not doing any raymarching for perf reasons.

@lisyarus@mastodon.gamedev.place avatar lisyarus , to random

I feel like once I populate the underwater regions with stones and seaweeds and fish, this could become a really sick screensaver

Adding the fake random wave bumps to the large-scale water. It looks gorgeous but also flickers A LOT, guess I'll have to tune it down based on camera angle

Every now and then I start my game to test something and suddenly the perf is 2x worse and I start investigating my profiling data and renderdoc captures and after about 15 minutes I realize there's a second instance of the game running 😂

First tests with large-scale water (just rendering, no simulation ofc). Pretty much everything's terrible, a lot of work ahead 😅

lisyarus OP ,
@lisyarus@mastodon.gamedev.place avatar

@hypolite Well, the flickering is expected (parent chunk not rendered because you're too close but the child chunk not loaded yet), I had this with terrain as well

Gaps between chunks are probably some uninitialised memory (which makes half of the water heights equal to zero), just need to find where it is!
