How it works

A repeating, always active command block runs a command only for players standing on a chosen block, checked with if block ~ ~-1 ~.

1. Jump pad (slime block)

/execute as @a at @s if block ~ ~-1 ~ slime_block run effect give @s levitation 1 20 true

A higher amplifier launches players higher. On Bedrock write effect @s levitation 1 20 true.

2. Speed pad (gold block)

/execute as @a at @s if block ~ ~-1 ~ gold_block run effect give @s speed 3 5 true

3. Warp pad (emerald block)

/execute as @a at @s if block ~ ~-1 ~ emerald_block run tp @s 100 64 100

Do not put another emerald block at the destination, or players bounce back and forth.

4. Healing floor (diamond block)

/execute as @a at @s if block ~ ~-1 ~ diamond_block run effect give @s regeneration 1 4 true

See the heal command.

5. Limit to one area

/execute as @a at @s if block ~ ~-1 ~ slime_block if entity @s[x=0,y=60,z=0,dx=50,dy=20,dz=50] run effect give @s levitation 1 20 true

6. Stop fall damage

/execute as @a at @s if block ~ ~-1 ~ slime_block run effect give @s slow_falling 6 0 true

A high levitation launch hurts on landing. Add this line in a chain command block after the jump pad block for six seconds of slow falling. Water at the landing spot also works, or turn off the fall_damage game rule (fallDamage before Java 1.21.11; see the game rule list).

7. Jump boost pad

/execute as @a at @s if block ~ ~-1 ~ lime_wool run effect give @s jump_boost 2 4 true

Players are not launched; they jump higher only when they press jump. Good for parkour gaps. A bigger amplifier means a higher jump.

8. Play a sound once when stepping on

# Repeating command block
execute as @a[tag=!onpad] at @s if block ~ ~-1 ~ slime_block run playsound minecraft:entity.slime.jump master @s
# Chain 1
tag @a remove onpad
# Chain 2
execute as @a at @s if block ~ ~-1 ~ slime_block run tag @s add onpad

Without the tag, the sound repeats every tick. Players on the pad carry the tag, so only players who just stepped on hear it. See the playsound command.
