double jump(multiple jump)

Hi, everyone. This is CBC
Today, I made the double jump ability into minecraft's datapack.

Players just need to press the space and then hold it when falling to trigger the second jump
If the player doesn't use the space when falling, it will not trigger
Triggering the second jump won't affect the nearby blocks
Players with jump_boast will not affect it, otherwise the effect is better
If you want to make more than two jumps, you can use this command
Select the former target and the latter value
The latter value is the limitation of the number of jumps the former target can make
Use this command to adjust the max number of jumps when players join
Multiplay can also use it, but it may be a little noisy And there will be achievements
Of course, you can also use it with the movement datapack I made before.
It will be more fun
