cps指令，每秒刷新

execute @a~~~ titleraw @s actionbar {"rawtext":[{"text":"cps： "},{"score":{"name":"@s","objective":"a"}},{"text":" block/s: "},{"score":{"name":"@s","objective":"c"}}]} 显示，重复执行开启

replaceitem entity @a[m=!c,tag=c] slot.hotbar 7 keep iron_sword 1 999 {"minecraft:item_lock":{"mode":"lock_in_slot"}}重复，不锁物品栏里怕人乱拿出来玩。 scoreboard players add @a[tag=c] e 1连锁有条件

scoreboard players operation @a[tag=c] a = @a[tag=c] e重复20的等待 scoreboard players set @a[tag=c] e 0连锁有条件

replaceitem entity @a[m=!c,tag=c] slot.hotbar 6 keep wool 1 0 {"minecraft:item_lock":{"mode":"lock_in_slot"},"minecraft:can_place_on":{"blocks":["minecraft:stonebrick","minecraft:wool"]}}重复，后面加的NBT标签可以去掉，我开的是冒险所以加上去了 scoreboard players add @a[tag=c] d 1有条件连锁

scoreboard players operation @a[tag=c] c = @a[tag=c] d重复20的延时 scoreboard players set @a[tag=c] d 0连锁有条件

tag用啥都行，每个人别重复就行了，这里举例用的是tag=x
