 } }
-</code> +</yarncode> 
- +接下来，我们将制作静态和动态酸变体的静态实例，以及一个酸桶。在您的 ''ModInitializer'' 中： 
-Next, we'll make static instances of still and flowing acid variants, and an acid bucket. In your **ModInitializer**: +<yarncode java [enable_line_numbers="true"]> 
- +public static class_3609 STILL_ACID; 
-<code java> +public static class_3609 FLOWING_ACID; 
- +public static class_1792 ACID_BUCKET; 
-     +  
-    public static Acid stillAcid; +@Override 
-    public static Acid flowingAcid; +public void onInitialize() { 
-     + STILL_ACID = class_2378.method_10230(class_7923.field_41173, new class_2960("tutorial", "acid"), new AcidFluid.Still()); 
-    public static BucketItem acidBucket; + FLOWING_ACID = class_2378.method_10230(class_7923.field_41173, new class_2960("tutorial", "flowing_acid"), new AcidFluid.Flowing()); 
- + ACID_BUCKET = class_2378.method_10230(class_7923.field_41178, new class_2960("tutorial", "acid_bucket"),  
-    @Override +        new class_1755(STILL_ACID, new class_1792.class_1793().method_7896(class_1802.field_8550).method_7889(1))); 
-    public void onInitialize() +  
-    { + // ... 
-     +} 
-        stillAcid = Registry.register(Registry.FLUID, new Identifier(MODID,"acid_still"), new Acid.Still()); +  
-        flowingAcid = Registry.register(Registry.FLUID, new Identifier(MODID,"acid_flowing"), new Acid.Flowing()); +// ... 
-         +</yarncode>
-        acidBucket = new BucketItem(stillAcid, new Item.Settings().maxCount(1)); +
-        Registry.register(Registry.ITEM, new Identifier(MODID,"acid_bucket"), acidBucket); +
-    }     +
-</code>+
  
-To make the custom fluid behave like water or lava, you must add it to a corresponding fluid tag: make a file "data/minecraft/tags/fluids/water.json" and write identifiers of your fluids in there: +为了使自定义流体表现得像水或熔岩，您必须将其添加到相应的流体标签中：对于水，制作 ''data/minecraft/tags/fluids/water.json'' 文件，并在其中写入流体 id： 
-<code json>+<code json [enable_line_numbers="true"]>
 { {
-  "replace": false, + "replace": false, 
-  "values": [ + "values": 
-    "modid:acid_still", + [ 
-    "modid:acid_flowing" + "tutorial:acid", 
-  ]+ "tutorial:flowing_acid" 
 + ]
 } }
 </code> </code>
  
-==== Making a fluid block ==== 
-Next we need to create a block which will represent acid in the world. **net.minecraft.block.FluidBlock** is the class we need to use, but for "mojang" reasons its constructor is protected. The solution is well-known - make a subclass of it and change the visibility of the constructor: 
  
-<code java> +==== 制作一个流体方块 ==== 
-public class BaseFluidBlock extends FluidBlock +接下来，我们需要在世界中创建表示酸的方块。''<yarn net.minecraft.class_2404>'' 是我们需要使用的类，但由于其构造器受保护，我们不能直接构造它。一种解决方法是制作子类或者匿名子类。这里我们展示后一种方式。在您的 ''ModInitializer'' 中： 
-{ +<yarncode java [enable_line_numbers="true"]> 
-    public BaseFluidBlock(BaseFluid fluid, Settings settings) +public static class_2248 ACID;
-    { +
-        super(fluid, settings); +
-    } +
-} +
-</code>+
  
-Now make a static block instance:+@Override 
 +public void onInitialize() { 
 + ACID = class_2378.method_10230(class_7923.field_41175, new class_2960("tutorial", "acid"), new class_2404(STILL_ACID, FabricBlockSettings.method_9630(class_2246.field_10382)){}); 
 +  
 + // ... 
 +}  
 +</yarncode>
  
-<code java> +既然我们有了这些静态对象，我们回到 ''AcidFluid'' 并补全被重写的方法： 
-    ... +<yarncode java [enable_line_numbers="true"]> 
-     +public abstract class AcidFluid extends TutorialFluid { 
-    public static FluidBlock acid;+ @Override 
 + public class_3611 method_15751() { 
 + return TutorialMod.STILL_ACID; 
 + } 
 +  
 + @Override 
 + public class_3611 method_15750() { 
 + return TutorialMod.FLOWING_ACID; 
 + } 
 +  
 + @Override 
 + public class_1792 method_15774() { 
 + return TutorialMod.ACID_BUCKET; 
 + } 
 +  
 + @Override 
 + protected class_2680 method_15790(class_3610 fluidState) { 
 + // method_15741 将流体状态的 LEVEL_1_8 转换为流体方块使用的 LEVEL_15 
 + return TutorialMod.ACID.method_9564().method_11657(class_2741.field_12538, method_15741(fluidState)); 
 + }
  
-    @Override + public static class Flowing extends AcidFluid { 
-    public void onInitialize() + @Override 
-    { + protected void method_15775(class_2689.class_2690<class_3611, class_3610> builder) { 
-     + super.method_15775(builder); 
-        ... + builder.method_11667(field_15900); 
-         + }
-        acid = new BaseFluidBlock(stillAcid, FabricBlockSettings.of(Material.WATER).dropsNothing().build()); +
-        Registry.register(Registry.BLOCK, new Identifier(MODID, "acid_block"), acid); +
-    }     +
-</code>+
  
-Now when we have these static objects, we go back to **Acid** class and complete the overridden methods:+ @Override 
 + public int method_15779(class_3610 fluidState) { 
 + return fluidState.method_11654(field_15900); 
 + }
  
-<code java> + @Override 
-public abstract class Acid extends BasicFluid + public boolean method_15793(class_3610 fluidState) { 
-{ + return false; 
-    @Override + } 
-    public Item getBucketItem() + }
-    { +
-        return Mod.acidBucket; +
-    } +
-     +
-    @Override +
-    protected BlockState toBlockState(FluidState fluidState) +
-    { +
-        //don't ask me what **method_15741** does... +
-        return Mod.acid.getDefaultState().with(FluidBlock.LEVEL, method_15741(fluidState)); +
-    }+
  
-    @Override + public static class Still extends AcidFluid { 
-    public Fluid getFlowing() + @Override 
-    { + public int method_15779(class_3610 fluidState) { 
-        return Mod.flowingAcid; + return 8; 
-    }+ }
  
-    @Override + @Override 
-    public Fluid getStill() + public boolean method_15793(class_3610 fluidState) { 
-    { + return true; 
-        return Mod.stillAcid; + } 
-    }+ } 
 +}   
 +</yarncode> 
 +===== 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]]）。
  
-    @Override +<yarncode java [enable_line_numbers="true"]> 
-    public boolean matchesType(Fluid fluid_1) +@Environment(EnvType.CLIENT)

-    } +
-     +
-    ... +
-     +
-}     +
-</code>+
  
-Now we can assert that the Acid class is complete.+ @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"),

 + ));
  
-===== Rendering setup =====+ BlockRenderLayerMap.INSTANCE.putFluids(class_1921.method_23583(), TutorialMod.STILL_ACID, TutorialMod.FLOWING_ACID);
  
-Time to do client-side things. In your **ClientModInitializer** you need to specify locations of sprites for your fluids and define their rendering. I will reuse water textures and just change the color applied to them.+ //if you want to use custom textures they needs to be registered.
