 在这里，我们将介绍自定义流体的创建。如果计划创建多个流体，建议创建一个抽象的基本流体类，在其中设置必要的默认值，这些默认值将在其子类中共享。我们还将使其像湖泊一样在世界中生成。 在这里，我们将介绍自定义流体的创建。如果计划创建多个流体，建议创建一个抽象的基本流体类，在其中设置必要的默认值，这些默认值将在其子类中共享。我们还将使其像湖泊一样在世界中生成。

 +===== 渲染设置 ===== 
 +为了让流体拥有纹理，或者与一个颜色绑定，你需要为其注册一个''FluidRenderHandler''。这里，我们重用水的纹理，并仅仅改变用于其上的颜色。为确保纹理渲染为半透明的，你可以使用 Fabric 的 ''BlockRenderLayerMap''（参见 [[blockappearance]]）。
  
-然后剩下要做的就是创建必要的Json文件和纹理，但是您现在应该知道该怎么做。+<yarncode java [enable_line_numbers="true"]> 
 +@Environment(EnvType.CLIENT) 
 +public class TutorialModClient implements ClientModInitializer {
  
-===== Generation in a world =====+ @Override 
 + public void onInitializeClient() { 
 + FluidRenderHandlerRegistry.INSTANCE.register(TutorialMod.STILL_ACID, TutorialMod.FLOWING_ACID, new SimpleFluidRenderHandler( 
 + new class_2960("minecraft:block/water_still"), 
 + new class_2960("minecraft:block/water_flow"), 
 + 0x4CC248 
 + ));
  
-要在世界上产生酸湖，可以使用在ModInitializer中创建的** net.minecraft.world.gen.feature.LakeFeature **： + BlockRenderLayerMap.INSTANCE.putFluids(class_1921.method_23583(), TutorialMod.STILL_ACID, TutorialMod.FLOWING_ACID);
-<code java> +
-         +
-        LakeFeature acidFeature = Registry.register(Registry.FEATURE, new Identifier(MODID,"acid_lake"), new LakeFeature(dynamic -> new LakeFeatureConfig(acid.getDefaultState())));+
  
 + //if you want to use custom textures they needs to be registered.
 + //In this example this is unnecessary because the vanilla water textures are already registered.
 + //To register your custom textures use this method.
 + //ClientSpriteRegistryCallback.event(PlayerScreenHandler.BLOCK_ATLAS_TEXTURE).register((atlasTexture, registry) -> {
 + //    registry.register(new Identifier("tutorial:block/custom_fluid_still"));
 + //    registry.register(new Identifier("tutorial:block/custom_fluid_flowing"));
 + //});
 +
 + // ...
 + }
 +}
 +</yarncode>
 +
 +如果你需要使用你自己的流体纹理，你可以参考原版资源包((''assets/minecraft/blockstates/water.json''\\ ''assets/minecraft/models/block/water.json''\\ ''assets/minecraft/textures/block/water_still.png''\\ ''assets/minecraft/textures/block/water_still.png.mcmeta''\\ ''assets/minecraft/textures/block/water_flow.png''\\ ''assets/minecraft/textures/block/water_flow.png.mcmeta''))作为一个模板。
 +
 +===== 在世界中生成 =====
 +为使得酸湖在世界中生成，你可以在你的''ModInitializer''中创建一个''net.minecraft.world.gen.feature.LakeFeature''，然后将其添加到你需要让它生成的生物群系中：
 +
 +<code java [enable_line_numbers="true"]>
 +// ...
 +
 +public static LakeFeature ACID_LAKE;
 +
 +// ...
 +
 +@Override
 +public void onInitialize()
 +{
 + // ...
 +
 + ACID_LAKE = Registry.register(Registry.FEATURE, new Identifier(MOD_ID, "acid_lake"), new LakeFeature(SingleStateFeatureConfig::deserialize));
 +
 + // 在沼泽中生成，类似于水湖，但是概率为40（数字越高，生成几率越低）
 + Biomes.SWAMP.addFeature(
 + GenerationStep.Feature.LOCAL_MODIFICATIONS,
 + ACID_LAKE.configure(new SingleStateFeatureConfig(ACID.getDefaultState()))
 + .createDecoratedFeature(Decorator.WATER_LAKE.configure(new ChanceDecoratorConfig(40)))
 + );
 +
 + // ...
 +}
 +
 +// ...
 </code> </code>
-然后将其放入所需的生物群系中以生成： 
-<code java> 
-        // I tell it to generate like water lakes, with a rarity of 40 (the higher is the number, the lesser is the generation chance): 
-        Biomes.FOREST.addFeature(GenerationStep.Feature.LOCAL_MODIFICATIONS, Biome.configureFeature(acidFeature, new LakeFeatureConfig(acid.getDefaultState()), Decorator.WATER_LAKE, new LakeDecoratorConfig(40))); 
-</code> 
-本教程到此结束。
