如题，直接给指令就可以了，可以显示在名字下面或者右边计分板

每秒时长+1，可自行修改

/scoreboard objectives add time dummy
/scoreboard objectives add temp dummy
/scoreboard objectives setdisplay sidebar time
或/scoreboard objectives setdisplay belowName time

循环：
/scoreboard players add Temp temp 1
/execute if score Temp temp matches 20 run scoreboard players add @a time 1
/execute if score Temp temp matches 20 run scoreboard players set Temp temp 0
