var C0FPacketConfirmTransaction = Java.type("net.minecraft.network.play.client.C0FPacketConfirmTransaction")
module.on("packet",function(event){
        if(event.getPacket() instanceof C0FPacketConfirmTransaction){
            var packetConfirmTransaction = event.getPacket()
            //your codes
        }
})

@chn-beimian 可以尝试编译成class再反翻译成java

As丶One

var RotationUtils = Java.type('net.ccbluex.liquidbounce.utils.RotationUtils');
var Rotation = Java.type('net.ccbluex.liquidbounce.utils.Rotation');
RotationUtils.setTargetRotation(new Rotation(mc.thePlayer.rotationYaw + 180, 86));

格挡伤害计算代码
if (!damageSrc.isUnblockable() && this.isBlocking() && damageAmount > 0.0F) {
damageAmount = (1.0F + damageAmount) * 0.5F;
}

mc可以在一个伤害周期内造成多段伤害，每造成一段伤害就会减少一次护甲耐久度

如果玩家在一个伤害周期内造成两段伤害为b和c，a=b+c
那么格挡后的伤害 (1 + b) * 0.5 + (1 + c) * 0.5 > (a + 1) * 0.5
格挡时空手暴击伤害为 1.25
格挡时空手无暴击+空手暴击伤害为1.75
