解决Minecraft自定义盔甲与默认盔甲重复渲染的问题

我最近在开发Minecraft模组时遇到了一个头疼的问题：想要替换游戏默认的盔甲渲染效果，但默认的“大型”盔甲模型始终会显示出来，导致两种盔甲叠加渲染的情况。

最初的代码实现

我一开始写的盔甲类代码是这样的：

package com.bnhc.items; 
import com.bnhc.client.render.CArmour; 
import com.bnhc.main.Main; 
import cpw.mods.fml.relauncher.Side; 
import cpw.mods.fml.relauncher.SideOnly; 
import net.minecraft.client.model.ModelBiped; 
import net.minecraft.entity.Entity; 
import net.minecraft.entity.EntityLivingBase; 
import net.minecraft.entity.player.EntityPlayer; 
import net.minecraft.item.ItemArmor; 
import net.minecraft.item.ItemStack; 

public class CCloth extends ItemArmor { 
    public CCloth(ArmorMaterial material, int armorType, int armorIndex) { 
        super(material, armorType, armorIndex); 
    } 

    public String getArmorTexture(ItemStack itemstack, Entity entity, int slot, String layer) { 
        if(((itemstack.getItem() == MIte.ua_sports_layer_1) || (itemstack.getItem() == MIte.ua_sports_layer_1))){ 
            return "bnhc:textures/armour/uasports_layer_1.png"; 
        } 
        return null; 
    } 

    CArmour armorModel = new CArmour(0.0F); 

    @Override 
    @SideOnly(Side.CLIENT) 
    public ModelBiped getArmorModel(EntityLivingBase entityLiving, ItemStack itemStack, int armorSlot) { 
        if (itemStack != null) { 
            if (itemStack.getItem() instanceof CCloth) { 
                int type = ((ItemArmor)itemStack.getItem()).armorType; 
                if (type == 1) { 
                    armorModel = Main.proxy.getArmorModel(0); 
                } else { 
                    armorModel = Main.proxy.getArmorModel(1); 
                } 
            } 
            if (armorModel != null) { 
                armorModel.isSneak = entityLiving.isSneaking(); 
                armorModel.isRiding = entityLiving.isRiding(); 
                armorModel.isChild = entityLiving.isChild(); 
                armorModel.heldItemRight = entityLiving.getEquipmentInSlot(0) != null ? 1 :0; 
                if(entityLiving instanceof EntityPlayer) { 
                    armorModel.aimedBow =((EntityPlayer)entityLiving).getItemInUseDuration() > 2; 
                } 
                return armorModel; 
            } 
        } 
        return armorModel; 
    } 
}

对应的客户端代理代码：

@Override 
public CArmour getArmorModel(int id) { 
    return customArmour; 
}

问题排查与解决

后来我终于找到问题根源：使用ModelBiped时默认已经会触发渲染逻辑，再加上客户端代理的额外模型获取设置，直接导致了重复渲染。只需要移除客户端代理相关的内容，同时调整盔甲模型的部位显示逻辑，就能彻底解决这个问题。

修改后的修复版本代码

    public CCloth(ArmorMaterial armorMaterial, int renderindex, int armortype,String name) { 
        super(armorMaterial, renderindex, armortype); 
    } 

    public String getArmorTexture(ItemStack stack, Entity entity, int slot, String type) { 
        if(stack.getItem() == MIte.ua_sports_chest) { 
            return Ref.MODID+ ":textures/armour/uasports_layer_1.png"; 
        }else if(stack.getItem() == MIte.ua_sports_leggs){ 
            return Ref.MODID+ ":textures/armour/uasports_layer_2.png"; 
        }else { 
            return null; 
        } 
    } 

    ModelBiped armorModel = new ModelBiped(); 

    @Override

                armorModel.bipedRightLeg.showModel = armorSlot == 2; 
                armorModel.bipedLeftLeg.showModel = armorSlot == 2; 
                armorModel.bipedBody.showModel = armorSlot == 1; 
                armorModel.bipedRightArm.showModel = armorSlot == 1; 
                armorModel.bipedLeftArm.showModel = armorSlot == 1; 
                armorModel.bipedHead.showModel = armorSlot == 0; 
                armorModel.isSneak = entityLiving.isSneaking(); 
                armorModel.isRiding = entityLiving.isRiding(); 
                armorModel.isChild = entityLiving.isChild(); 
                armorModel.heldItemRight = entityLiving.getEquipmentInSlot(0) != null ? 1 :0; 
                if(entityLiving instanceof EntityPlayer){ 
                    armorModel.aimedBow =((EntityPlayer)entityLiving).getItemInUseDuration() > 2; 
                } 
                return armorModel; 
            } 
        } 
        return armorModel; 
    } 
}
