Adjusted speed does not affect sprint-jumping/falling/floating with levitation/floating with NoGravity

When the player's speed is adjusted, the affects are not applied when sprint-jumping. Players under the affects of slowness potions, for instance, can still sprint-jump at nearly normal speeds. They are only slowed during the brief moments that they touch the ground.

Similarly, players in creative mode do not have their flying speed affected by speed potions. It seems Minecraft does not apply these affects to player motion when the player is airborne in general.

Steps to Reproduce

  • Give yourself the slowness effect:

    /effect give @s minecraft:slowness 100 5 true
  • Start running and take note of the speed at which you're traveling.

  • Start running and jumping and notice how you are now traveling much faster.

Observed Behavior

Adjusted movement speed isn't considered when mid-air.

Expected Behavior

Adjusted movement speed would be considered even when mid-air.

Bumpity? I'm not sure why this was overlooked when the effects were introduced, but it'd be very nice to have it fixed. At least a response if no fix is planned.

Or perhaps allow me to join Mojang so I can help you guys fix it myself? šŸ˜‰

Stop bumping.

I thought this was intended. If you look at Sethbling's Video on this it explains that the faster you are the slower your sprint jump goes (well it depends on which speed you set the potion to). Although he uses MCEdit to help make custom potions, I think this may explain some things. Hopefuly I don't look like an idiot and read the explanation wrong but I hope this helps <:)http://www.youtube.com/watch?v=SCsoexRngNs

Will there at least be a response to this?

@HubbiGamingTV dude, if it'd be OP, then everything is OP. Like, with this bug one can just sprintjump away of the effect. Right now, slowness effect is completely useless because of this bug.

That's why it is a bug that should be fixed asap. I still dont understand why it hasn't yet been fixed. It's anchient, there is a mob that uses it, there is no incentive in using the slowness effect as a debuff and it even is supposed to be the """downside""""of a powerful potion effect

Can confirm in 23w05a

Can confirm in 1.20.4, also applies to the `minecraft:generic.movement_speed` attribute in addition to potion effects
