import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;为何报错？

报错可能是因为缺少相关的依赖或者该类的引入方式不正确。请确认以下几点：

1. 确保已正确导入 `net.minecraftforge.fml.common.event.FMLPreInitializationEvent` 类。可以使用 IDE 的自动导入功能或手动导入该类。

2. 确保项目中已经添加了正确的依赖。对于 Forge Mod 开发，需要添加 Forge 的相关依赖。可以查看项目的 `build.gradle` 或 `pom.xml` 文件，确认是否已添加了正确的依赖。

3. 如果以上操作都正确，但仍然报错，可能是由于版本不兼容导致的。请确认所使用的 Forge 版本与其他相关库的版本是否匹配。

如果问题仍然存在，请提供更详细的错误信息，以便更好地帮助解决问题。

这段代码中的 `getRegistry()` 报错很可能是由于 `RegistryEvent` 类型不正确或者在 `RegistryEvent.Register<Item>` 中没有正确地指定泛型参数。请将 `RegistryEvent.Register` 修改为 `Register<Item>`，并将 `public static void registerItems(RegistryEvent.Register<Item> event)` 方法中的参数类型也修改为 `Register<Item>`。另外，你可以尝试将 `registerItem()` 方法的访问级别改为 public，以避免访问限制问题。如果还存在问题，请提供更详细的错误信息和代码上下文，这样我才能更好地帮助你。

这段代码中存在一个错误：方法 `mc.draw()` 不存在。

应该使用 `Gui.drawRect()` 方法来绘制矩形。

正确的代码应该是：

package com.HudShow.hud.gui;

import com.HudShow.hud.HudShow;
import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.Gui;

@Mod.EventBusSubscriber(modid = HudShow.MODID)
public class HealthHud extends Gui {

    private final Minecraft mc;

    public HealthHud() {
        mc = Minecraft.getMinecraft();
    }

    public void render() {
        float health = mc.player.getHealth();
        float maxHealth = mc.player.getMaxHealth();
        int width = (int) ((health / maxHealth) * 120);
        Gui.drawRect(1, 1, 1 + width, 21, 0xFFFF0000);

        String healthShow = String.valueOf(mc.player.getHealth());
        int StringWidth = (width - mc.fontRenderer.getStringWidth(healthShow)) / 2;
        mc.fontRenderer.drawString("§l" + healthShow, StringWidth + 1, 6, 120, true);
    }

    public void render2(RenderGameOverlayEvent event) {
        int posX = (event.getResolution().getScaledWidth()) / 2;
        int posY = (event.getResolution().getScaledHeight()) / 2;
        GlStateManager.tryBlendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO);
        Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("hud:textures/gui/frame_health.png"));
        drawModalRectWithCustomSizedTexture(posX - 207, posY - 112, 0, 0, 91, 45, 182, 91);
    }
