Please don't talk to me about this. The first couple of hours of this update were quite enjoyable, and then the rest was one of the most miserable times I've had modding. This has been a real slog, partly due to some large MC changes (item models are a great change, but a pain to adapt to), and partly due to mental health reasons — honestly, I've opened up my IDE so many times, and then just closed it because I've hated the thought of even working on this. I will publish this to my maven, so mod authors can depend on it, but I have no plans to publish a 1.21.4 version. 1.21.5 is right around the corner (again, with some cool, but no-doubt painful changes), and I need some time to focus on some breaking changes. This commit actually includes the 1.21.3 update — the git history got so messy here, so I just clobbered the whole thing. Sorry. == Rendering == - Remove TBO monitor renderer: There was a big overhaul to how shaders are defined and loaded in 1.21.2. It might have been possible to update the monitor shader code to this version, it doesn't see much use nowadays, so let's just delete it. This is a real shame — the TBO renderer was one of my favourite projects I've worked on. Unfortunately, it just doesn't seem worth the ongoing maintenance burden. It lives on in the standalone emulator :D. - Similarly, the VBO rendering code got a bit of an overhaul. We no longer use a custom VBO subclass, and instead just hack vanilla's to support changing the number of vertices rendered. This does mean we need to construct a MeshData, rather than a raw ByteBuffer. This isn't too hard, but not sure how it'll play with Iris. Given recent vanilla performance improvements, maybe we can remove our Unsafe code and use a normal BufferBuilder now. - Remove our custom emissive model code, now that vanilla supports it. We should add emissive textures to some other models at some point. - Remove mod-loader specific model code, and replace it with vanilla's ItemModel. This does constrain the design of turtle upgrade modellers quite a bit — we now only accept an untransformed BakedModel or a transformed ItemStack model. We may relax this in the future, unclear. This change does mean that updsidedown turtles are broken. RIP :(. - Entity rendering now separates reading state from the entity from actual rendering. This means we need to pass some extra state around for item frames. Easy on Forge, but requires a mixin on Fabric. == Recipes == There were several major changes to ingredients this update. The code here hasn't been very well tested right now — might be nice to add some game tests for this. - Ingredients can no longer be constructed directly from a tag key (it needs to be fetched from the current registries), so the recipe generation code needs a bit of a reshuffle. - DiskRecipe now accepts a custom list of ingredients, rather than being hard-coded (fixes #1755). Recipes can now return custom `RecipeDisplay`s used to show a recipe in the crafting book. We use this to replace the impostor recipes. I'm not entirely sure how well this'll play with other recipe mods. Here's hoping. - Similarly, our recipe mod integration has been updated to use RecipeDisplay. We had to do this as ingredients no longer accept arbitrary ItemStacks (only a specific item). == Misc == - Blocks/items now need to know their ID ahead of time (so they can compute their description). This requires some reshuffling to the registration code, but it's pretty minor. - updateShape and neighborChanged no longer take a direction (the Orientation is mostly null) and so invalidates all redstone and peripherals. - All the positions were lowered by one in game tests. It's a good change (they now match the positions in structures), but annoying to update for!
