简单的Forge事件使用，版本1.20.1。

ForgeEvents.onEvent("net.minecraftforge.event.entity.living.LivingHurtEvent", event =>{
    const {
        entity, // target
        source // damage source
    } = event;
    if (source.actual == null) return
    if (!source?.actual.isPlayer()) return
    /**
     * @type {Internal.Player}
     */
    const player = source.actual;
    const EXTRA_DAMAGE = 10;
    if (player.health <= player.maxHealth * 0.5) {
        event.setAmount(event.getAmount() + EXTRA_DAMAGE);
    }
})

这里是用特殊武器时替换伤害类型的代码 很奇怪的是 我在写这个代码的时候填入damage的传参 出现的问题很奇怪 伤害只能偶尔被替换成正确的类型 而且伤害会变成原伤害的一半 填入damage*2 的传参 伤害被正确替换了 就很神秘（）

let $DamageType = Java.loadClass('net.minecraft.world.damagesource.DamageTypes')
ForgeEvents.onEvent("net.minecraftforge.event.entity.living.LivingHurtEvent",event=>{
    const {source,entity} = event;
    const actual = source.actual;
    if(actual == null) return;
    if(source.getType() != "player") return;
    let player = event.source.player;
    let damage = event.amount;
    if(player && player.mainHandItem.id == 'juitar:shadow_katana')
        {
            let powerAttack = player.mainHandItem.nbt.getByte("powerAttack");
            if(powerAttack == 1)
            {
            entity.attack(entity.level.damageSources().source($DamageType.MAGIC,player),damage*2);
            event.canceled = true;
            player.heal(4);
            player.mainHandItem.nbt.putInt("powerAttack",0) ;
            }
        }
        else if(player && event.source.player.mainHandItem.id == 'juitar:radiation_glaive')
