示例.txt

function onUse(event) {
    var sf = "creeper_spawn_egg{EntityTag:{id:\"minecraft:iron_golem\"}}"; // 材质+铁傀儡
    var player = event.getPlayer();
    var inv = player.getInventory();
    var itemInMainHand = inv.getItemInMainHand();

    if (itemInMainHand != null && itemInMainHand.getAmount() > 0) {
        var amount = itemInMainHand.getAmount();
        itemInMainHand.setAmount(0);
        runOpCommand(player, "give " + player.getName() + " " + sf + " " + amount);
    }
}

上面的是右键不会消耗

function onUse(event) {
    var mob = "creeper_spawn_egg{EntityTag:{id:\"minecraft:iron_golem\"}}"; // 材质+铁傀儡
    var player = event.getPlayer();
    var inv = player.getInventory();
    var itemInMainHand = inv.getItemInMainHand();

    if (itemInMainHand != null && itemInMainHand.getAmount() > 0) {
        var amount = itemInMainHand.getAmount();
        itemInMainHand.setAmount(itemInMainHand.getAmount() - 1);
        runOpCommand(player, "give " + player.getName() + " " + mob + " " + amount);
    }
}

指令中id后的/"代表转义，因为外面还有一层双引号，双引号内的所有双引号都得用/"
