帮忙看一下代码(mod制作)

我要做一个模组。该模组实现了类似于原神的拾取方式，代码总是有问题，请帮忙看下：
ClientEvents.java

package com.example.InteractReborn;
import net.minecraft.client.Minecraft;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.world.InteractionHand;
import net.minecraft.world.entity.item.ItemEntity;
import net.minecraftforge.client.event.InputEvent;
import net.minecraftforge.event.TickEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import org.lwjgl.glfw.GLFW;
import java.util.ArrayList;
import java.util.List;
@Mod.EventBusSubscriber(modid = Main.MODID, value = Mod.EventBusSubscriber.Bus.FORGE)
public class ClientEvents {
public static List<ItemEntity> nearbyItems = new ArrayList<>();
public static int selectedIndex = 0;
public static final ResourceLocation SELECTED_BG = new ResourceLocation(Main.MODID, "textures/gui/true.png");
public static final ResourceLocation UNSELECTED_BG = new ResourceLocation(Main.MODID, "textures/gui/false.png");
@SubscribeEvent
public static void onClientTick(TickEvent.ClientTickEvent event) {
if (event.phase == TickEvent.Phase.END) {
Minecraft mc = Minecraft.getInstance();
if (mc.level != null && mc.player != null && Config.modEnabled) {
nearbyItems = mc.level.getEntitiesOfClass(ItemEntity.class,
mc.player.getBoundingBox().inflate((float) Config.pickupRange));
} else if (!nearbyItems.isEmpty()) {
nearbyItems.clear();
selectedIndex = 0;
}
}
}
@SubscribeEvent
public static void onMouseScroll(InputEvent.MouseScrollingEvent event) {
if (Config.modEnabled && !nearbyItems.isEmpty()) {
double delta = event.getDeltaY();
int direction = delta > 0 ? -1 : 1;
selectedIndex = (selectedIndex + direction + nearbyItems.size()) % nearbyItems.size();
event.setCanceled(true);
}
}
@SubscribeEvent
public static void onKeyPress(InputEvent.Key event) {
if (event.getKey() == GLFW.GLFW_KEY_F && event.getAction() == GLFW.GLFW_PRESS) {
Minecraft mc = Minecraft.getInstance();
if (Config.modEnabled && mc.gameMode != null && !nearbyItems.isEmpty()) {
ItemEntity selected = nearbyItems.get(selectedIndex);
if (selected.isAlive()) {
mc.gameMode.interact(mc.player, selected, InteractionHand.MAIN_HAND);
}
}
}
}
}
