我已經為 Minecraft Mods 編程了 3 週並有一個問題。我想要，可變距離是你穿上多少盔甲。這是我的代碼：
package com.E2Z1.pickaxemod.item.custom;
import net.minecraft.world.entity.Entity;
import net.minecraft.world.entity.EquipmentSlot;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.item.ArmorItem;
import net.minecraft.world.item.ArmorMaterial;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.Level;
import com.E2Z1.pickaxemod.item.ModArmorMaterial;
public class ModArmorItem extends ArmorItem {
public ModArmorItem(ArmorMaterial material, EquipmentSlot slot, Properties settings) {
super(material, slot, settings);
}
@Override
public void inventoryTick(ItemStack stack, Level world, Entity entity, int slot,
boolean selected) {
if(!world.isClientSide()) {
if(entity instanceof Player) {
Player player = (Player)entity;
GlobalVar.distance = howmanyarmor(ModArmorMaterial.PICKAXE_ARMOR, player);
}
}
super.inventoryTick(stack, world, entity, slot, selected);
}
private int howmanyarmor(ArmorMaterial material, Player player) {
ArmorItem boots = ((ArmorItem)player.getInventory().getArmor(0).getItem());
ArmorItem leggings = ((ArmorItem)player.getInventory().getArmor(1).getItem());
ArmorItem breastplate = ((ArmorItem)player.getInventory().getArmor(2).getItem());
ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem());
ItemStack boots2 = player.getInventory().getArmor(0);
ItemStack leggings2 = player.getInventory().getArmor(1);
ItemStack breastplate2 = player.getInventory().getArmor(2);
ItemStack helmet2 = player.getInventory().getArmor(3);
int numberofarmor = 0;
if (!helmet2.isEmpty()) {
if (helmet.getMaterial() == material){
numberofarmor =+ 1;
}}
if (!breastplate2.isEmpty()) {
if (breastplate.getMaterial() == material){
numberofarmor =+ 1;
}}
if (!leggings2.isEmpty()) {
if (leggings.getMaterial() == material){
numberofarmor =+ 1;
}}
if (!boots2.isEmpty()) {
if (boots.getMaterial() == material){
numberofarmor =+ 1;
}}
return numberofarmor;
}
}
當我開始世界時，會出現此錯誤：
Caused by: java.lang.ClassCastException: class net.minecraft.world.item.AirItem cannot be cast to class net.minecraft.world.item.ArmorItem (net.minecraft.world.item.AirItem and net.minecraft.world.item.ArmorItem are in module [email protected] of loader 'TRANSFORMER' @2c8662ac)
Forge 版本：37.0.104 Minecraft 版本：1.17.1
（抱歉英語不好）
我希望你能幫忙
我並不是真的喜歡getArmorMinecraft 模組，但是看起來你正在使用-Getters 玩家角色的盔甲碎片進行檢索。如果玩家在插槽中沒有穿任何盔甲，我想，你不會收到一個實例，ArmorItem而是收到一個AirItem（基本上是一個空插槽）。
因此，您可能需要實際檢查收到的實例類型。以同樣的方式，您檢查public void inventoryTickifentity是 type 的實例Player。
結果實現可能如下所示：
private int howmanyarmor(ArmorMaterial material, Player player) {
int numberofarmor = 0;
Item bootsItem = player.getInventory().getArmor(0).getItem();
if (bootsItem instanceof ArmorItem) {
ArmorItem boots = (ArmorItem)bootsItem;
ItemStack boots2 = player.getInventory().getArmor(0);
if (!boots2.isEmpty()) {
if (boots.getMaterial() == material){
numberofarmor =+ 1;
}}
}
// [... re-do for remaining slots ...]
return numberofarmor;
}
