This week on Five Block Fridays, we're creating a charged jump feature using just 5 command blocks.

If you want to add different levels of charging, just copy blocks 4 and 5, changing the crouch timer value and level of jump boost or pitch of the tone.

If you want the jump boost to persist as long as the player stays crouched, replace 'crouch_timer=20' in command 5 with 'crouch_timer=20..'.

Here's the commands used in this video:

Command 1 - Scoreboard Setup:
scoreboard objectives add crouch_timer minecraft.custom:minecraft.sneak_time

Command 2 - Score Reset:
execute as @p at @s anchored eyes positioned ^ ^ ^ unless entity @s[distance=1.0..1.5,nbt={OnGround:1b}] run scoreboard players set @s crouch_timer 0

Command 3 - Effect Clearing:
effect clear @a[scores={crouch_timer=0..19},nbt={ActiveEffects:[{Id:8,ShowParticles:0b}]},nbt=!{ActiveEffects:[{Id:8,ShowParticles:1b}]}] minecraft:jump_boost

Command 4 - Jump Charged Tone:
execute as @a[scores={crouch_timer=20},nbt=!{Inventory:[{Slot:101b}]}] at @s run playsound minecraft:block.note_block.bass player @s ~ ~ ~ 1 1 1

Command 5 - Adding Effect:
effect give @a[scores={crouch_timer=20},nbt=!{Inventory:[{Slot:101b}]}] minecraft:jump_boost 1 1 true
