首先确定一下《我的世界》版本是1.7.2，其他版本不保证生效，然后输入/give @p minecraft:diamond_sword 1 0 {AttributeModifiers:[{Operation:0,UUIDLeast:1,UUIDMost:1,Amount:9000000000.0,AttributeName:generic.attackDamage,Name:Attack},，完整代码如下所示。

你版本是1.7.2就可以输入
/give @p minecraft:diamond_sword 1 0
{AttributeModifiers:[{Operation:0,UUIDLeast:1,UUIDMost:1,Amount:9000000000.0,AttributeName:generic.attackDamage,Name:Attack},
{Operation:0,UUIDLeast:2,UUIDMost:2,Amount:9000000000.0,AttributeName:generic.knockbackResistance,Name:Knockback},
{Operation:0,UUIDLeast:3,UUIDMost:3,Amount:0.0,AttributeName:generic.followRange,Name:Follow},
{Operation:0,UUIDLeast:4,UUIDMost:4,Amount:1000.0,AttributeName:generic.maxHealth,Name:Health},
{Operation:0,UUIDLeast:5,UUIDMost:5,Amount:2.0,AttributeName:generic.movementSpeed,Name:Speed}]}
出来的是钻石剑，属性有：1.生物跟随距离：5000.0(就是生物在五千格子内可发现你)2.最大生命：9000000(拿着它就会生效)3.击退抗性：9000000000(酱紫就不会被击退)4.攻击伤害：9000000000(秒杀一切BOSS)
