[1.20.2] RecipeSerializer Codec requirement

Posted October 28, 20231 yr

Hi,
I am just updating my mod from 1.20.1 to 1.20.2 and I saw a big change for the custom RecipeSerializers, they now require Codec<?> serialization instead of a simple fromJson() function.
Unfortunately, I am struggling with setting up the Codec for a few of the serialization features:

- Using the Forge "mod_loaded" condition (the file should not be loaded when a mod is missing)

- Loading an Ingredient field

Current Codec Code:

Spoiler

    public static final Codec<EnvironmentData> CODEC = RecordCodecBuilder.create((builder) -> builder
            .group(
                Ingredient.CODEC_NONEMPTY.fieldOf("input").forGetter(EnvironmentData::getInputItem),
                BlockState.CODEC.fieldOf("render").forGetter(EnvironmentData::getRenderState),
                Codec.FLOAT.fieldOf("growModifier").forGetter(EnvironmentData::getGrowModifier),
                Codec.list(Codec.STRING).fieldOf("categories").forGetter(EnvironmentData::getCategories)
            ).apply(builder, EnvironmentData::new));

For the first problem, previously the "mod_loaded" condition was automatically taken into account, but I suppose that now it changed and has to be taken care of in the codec?
For the second problem, I am trying to read the Ingredient with the CODEC_NONEMPTY from the Ingredient class, but I get the following error:

The "cagedmobs:environments/red_mushroom_block" JSON recipe:

Spoiler

{
	"type": "cagedmobs:environment_data",
	"conditions": [
		{
			"type": "forge:mod_loaded",
			"modid": "cagedmobs"
		}
	],
	"input": {
		"item": "minecraft:red_mushroom_block"
	},
	"render": "minecraft:red_mushroom_block",
	"growModifier": 1.0,
	"categories": ["mycelium"]
}

As seen here, the Ingredient input item is in the form of a nested JSON:

"input": {
		"item": "minecraft:red_mushroom_block"
}

The problem is not the 'input' field its' the 'render' field.
You expect there a BlockState but 'minecraft:red_mushroom_block' is a Block.

If you need no BlockState you can use ForgeRegistries.BLOCKS.getCodec() instead of BlockState.CODEC.
If you need explicit a BlockState take a look at the Codec which fields are required.

Thank you, and what about the "mod_loaded" condition with Codecs?

The recipe conditions are added by Forge, there should be a codec from Forge somewhere that you can use.

There is, but I am not good at the codecs, how do I use them as conditional functions?

Can you please explain in more detail what you mean by that?

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
