[Minecraft Java] How to make a Minigame Clock

Описание

--All commands available in description--
This is a small, but tough, command system that you can use to make an in-game clock for your minigames and adventure maps. This is my first time creating a tutorial and I'd like to do more, so let me know what I can improve!

A. SETUP COMMANDS
A1. /scoreboard objectives add TimerScore dummy
A2. /scoreboard objectives add TimerMinutes dummy
A3. /scoreboard objectives add TimerSeconds dummy
A4. /bossbar add 1 {"text":"0:0"}
A5. /bossbar set minecraft:1 players @a ***This has a small error in the video. Correct version here***
A6. /bossbar set minecraft:1 max 300

B. RESET FUNCTION
B0. /setblock ~1 ~ ~ air (Activator)
B1. /scoreboard players set #TimerEntity TimerScore 300
B2. /scoreboard players set #TimerEntity TimerMinutes 5
B3. /scoreboard players set #TimerEntity TimerSeconds 0
B4. /bossbar set minecraft:1 name ["",{"score":{"name":"#TimerEntity","objective":"TimerMinutes"}},{"text":":"},{"score":{"name":"#TimerEntity","objective":"TimerSeconds"}}]
B5. /execute store result bossbar minecraft:1 value run scoreboard players remove #TimerEntity TimerScore 0

C. TICK FUNCTION
C0. 4-4-2 Repeater Clock or Similar (Activator)
C1. /execute store result bossbar minecraft:1 value run scoreboard players remove #TimerEntity TimerScore 1
C2. /scoreboard players remove #TimerEntity TimerSeconds 1
C3. /execute if score #TimerEntity TimerSeconds matches ..-1 run scoreboard players remove #TimerEntity TimerMinutes 1
C4. /execute if score #TimerEntity TimerSeconds matches ..-1 run scoreboard players set #TimerEntity TimerSeconds 59
C5. /bossbar set minecraft:1 name ["",{"score":{"name":"#TimerEntity","objective":"TimerMinutes"}},{"text":":"},{"score":{"name":"#TimerEntity","objective":"TimerSeconds"}}]
C6. /execute if score #TimerEntity TimerScore matches ..-1 run setblock X Y Z minecraft:redstone_block ***You need to replace [X Y Z] with the coordinates of your 'repeater choke' so it stops the clock successfully.***
