Build a parkour course

1. The checkpoint function

When a player stands on a checkpoint, set their spawn point to where they are, confirm it with an action-bar message and a chime, and tag them so we know they've started. spawnpoint @s with no coordinates uses the player's current position.

# functions/park/checkpoint.mcfunction
spawnpoint @s
title @s actionbar Checkpoint reached!
playsound random.orb @s
tag @s add checkpoint

2. The finish line

A separate block type ends the course — a big title, a victory sound, and clear the tag so they can run it again.

# functions/park/finish.mcfunction
title @s title Course complete!
playsound random.levelup @s
tag @s remove checkpoint

3. Wire the blocks

A tick.json checks every player each tick: emerald under their feet fires a checkpoint, diamond fires the finish. Place emerald blocks at each safe landing and a diamond block at the end.

# functions/tick.mcfunction (via tick.json)
execute as @a at @s if block ~ ~-1 ~ emerald_block run function park/checkpoint
execute as @a at @s if block ~ ~-1 ~ diamond_block run function park/finish

Re-setting spawn every tick while standing on the same block is harmless — but the sound and title will repeat. See "Make it yours" below to fire each checkpoint only once.

Make it yours

• · Give each checkpoint its own number by using a different block (gold = 2, iron = 3) and its own tag.
• · Silence the repeat: only chime when the player doesn't already have a at_cp tag, and clear that tag when they step off.
• · Add a fall-death catch: if a player drops below a Y level, /tp them back to their spawn.
• · Track a timer with a scoreboard objective for a speedrun leaderboard.

See it in Minecraft

Step onto a checkpoint pad and it fires — your spawn moves here and the screen confirms it, so a fall just sends you back to the last checkpoint.

The floating course in the shot is a handful of blocks — run this once to place a jump run with an emerald checkpoint at the top:

# functions/park/build.mcfunction
setblock ~ ~ ~2 quartz_block
setblock ~1 ~1 ~4 lime_concrete
setblock ~ ~2 ~6 quartz_block
setblock ~1 ~3 ~8 lime_concrete
setblock ~ ~4 ~10 quartz_block
setblock ~ ~5 ~12 emerald_block
