所以基本上我一直在互联网上搜索一种在持有物品时添加药水效果的方法。我发现了很多结果，但似乎没有一个真正有效。我的主要问题是，当我达到添加药水效果时，它会抛出错误，因为我试图使用非静态来访问摘要。我尝试了几次@Overide，但似乎从来没有起作用。我仍然需要在 forge 中注册，因为这就是它的更新方式，但是当我使用 @SubscribeEvent
时添加 PlayerEntity 不起作用package blitz.weapon.weaponmod;

这基本上是我整个模组的代码，有人能给我任何指示吗？ （这是我的第一篇文章，如有错误请见谅）
如果您想在您的 Item-Class 中使用该方法，那么这将对您有所帮助： （当然你可以在这里使用 @OnlyIn(Dist.DEDICATED_SERVER) 或在方法 if(!worldIn.isRemote()) {...})
@Override
public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
if (entityIn instanceof PlayerEntity) {
PlayerEntity player = (PlayerEntity) entityIn;
if (player.getHeldItem(Hand.MAIN_HAND).getItem() == ModItemRegistry.TESTITEM) {
player.addPotionEffect(new EffectInstance(Effects.INVISIBILITY, 1000));
}
}
}
但是如果你想在另一个类中使用该方法，那么可以使用：
@SubscribeEvent
public void onPlayerTick(TickEvent.PlayerTickEvent event) {
if (event.side.isServer() && event.phase == TickEvent.Phase.START) {
ItemStack stack = Objects.requireNonNull(event.player.getHeldItem(Hand.MAIN_HAND));
if (stack.getItem() == ModItemRegistry.TestItem) {
event.player.addPotionEffect(new EffectInstance(Effects.INVISIBILITY, 1000));
}
}
}
