java - 我的世界 java 中的 maxStackSize 程序不起作用可能是 onRightClick 不起作用的原因

Question

我目前正在沙盒 java 游戏 minecraft 中开发一个 mod，我制作了一个右键单击将玩家推向空中的项目。不幸的是，这不起作用，当我尝试在游戏中激活该能力时，没有任何反应。该程序的代码如下：

package net.minecraft.src;
public class PhageWings extends Item{

public PhageWings(int par1){ 
super(par1);
this.maxStackSize = 1;
this.setCreativeTab(CreativeTabs.tabTransport);
}

public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer){
    entityplayer.motionY += 1; //fling player up in the air 

return itemstack;
}
}

我正在研究一个类似的项目，它给了我相同的结果，代码也如下：package net.minecraft.src;

public class PhageWand extends Item {
public PhageWand(int par1) { 
super(par1);
this.maxStackSize = 1;
this.setCreativeTab(CreativeTabs.tabTransport);
}
public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
    if (par3EntityPlayer.capabilities.isCreativeMode)
    {
        return par1ItemStack;
    }
    else if (par3EntityPlayer.ridingEntity != null)
    {
        return par1ItemStack;
    }
    else
    {
        --par1ItemStack.stackSize;
        par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!par2World.isRemote)
        {
            par2World.spawnEntityInWorld(new EntityEnderPearl(par2World, par3EntityPlayer));
        }

        return par1ItemStack;
    }
}
}
