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

I think this is very clearly a bug. When you jump you expect forward motion to carry through. It's natural. Jumping in Minecraft at the moment is far from natural, and it has a very detrimental effect on gameplay (especially when potions and boosts are being used).

This is clearly a bug as far as I'm concerned. Instead of having this get insta-nixed by the OPINIONS of the moderators, how about you leave this open so that MOJANG can look at it.

Agree. Why was this labeled invalid?

A player cannot move AT ALL when walking, so why should he be allowed to sprint? if walkspeed = 0 just cancel sprint.

TrazLander - See the comment above from [Mod] Anon Ymus for why it is considered invalid.

How is this not a bug.

You can't surely tell me that its 100% intended for players to sprint jump normally when a splash potion of slowness is thrown on them?

Reopened

I have a feeling this is intentional. As of Minecraft Wiki (http://minecraft.gamepedia.com/Status_effect#List_of_effects ):
Speed: Increases walking speed by 20%
It also makes sense. The potion is supposed to 'make your legs go faster', and in real life, you can't swing your legs while airborne to move forward.

Simple, common-sense physics dictates that forward momentum should be preserved when you jump. If you're moving quickly on the ground, you should not lose speed when you jump forward in excess of the loss due to air resistance.

When people jump while standing still, they shouldn't have the speed modifier.
When people jump while sprint jumping, it doesn't make sense to give them the same speed multiplier as if they were standing still.
Sprint jumping is specifically intended to do long jumps, and ignoring the speed potion is weird.

Why is this being postponed? This is a huge bug. It allows players to walk at normal speed while jumping for the entire duration of slowness effect.

Torabi, common-sense physics dictates that forward moment should be preserved while jumping, but this bug allows momentum to be gained while in the air. Either you don't understand simple physics, or haven't looked at the bug. It's as much a bug as MC-40949

Mojang, how is this in the game for so long? Players shouldn't be able to negate slowness just by starting to jump.

"Postponed" means that it won't be fixed soon, but nobody has claimed it wasn't a bug (since 2016 at least). Postponing can have various reasons, for example if something is hard to fix. I don't know enough about how player movement is handled in the code to tell you how hard or easy this would be to fix.

@unknown, my comment was in response to the claims that this wasn't a bug. As for why it's been postponed, the reason is much the same as why it's been in the game for so long. The player movement code is ancient and ugly. Most of the bugs related to it would be difficult to fix, and there's a considerable risk that attempting to do so would introduce new bugs. It would be safer, cleaner, and easier to overhaul that section of code completely than to make changes to it, and thus most bugs related to it will probably be postponed until they can fit it into their development schedule.

The previous workaround for this when using commands to administratively stop a player from moving was to give them a jump boost of greater than 128 (effectively a negative jump boost, due to signed/unsigned byte value conversions).
This workaround no longer works as of 1.14.2-pre2, making this issue a much bigger one again than it has been.
I'd be happy if there was at least a working workaround.

In 1.14.2-pre2 you don't even need to be sprinting. With a slowness effect of 127 and normal jumping you can progress at almost normal walking pace.

Since this was reopened, it affects 1.14, 1.14.1, 1.14.2, 1.14.3, and 1.14.4.

Confirmed for 20w13b

In 1.16.1

In 1.16.3

This also happens with the new freezing effect in 20w46a.

I'd like to request the ownership of this report as the reporter has been inactive since March 2014.

Can confirm in 20w48a.

Can confirm in 20w51a. Requesting Ownership.

Can confirm in 21w03a.

Can confirm in 21w05a.

Can confirm in 21w05b.

Can confirm in 21w06a.

Can confirm in 21w07a. Video attached.

Can confirm in 21w11a.

Can confirm in 21w15a. Here are some steps to reproduce this issue:

Steps to Reproduce:

• Effect yourself with slowness.

/effect give @s minecraft:slowness 100 5 true

• Start running and notice the speed at which you are traveling at.

• Start running and jumping.
  → ❌  Notice how you are now traveling much faster.

Can confirm in 21w17a.

Can confirm in 1.17.

Can confirm in 1.17.1.

I am able to confirm this behavior in 21w39a. Here are some extra details regarding this issue.

The Bug:

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

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.

Can confirm in 1.18.1.

Can confirm in 1.18.2.

Can confirm in 1.19.

speed only effects ground movement to stop it from being overpowerd

Can confirm in 1.19.1. @unknown, the "Mojang Priority" assigned to this ticket states otherwise and that the current behavior is a valid bug.

Can confirm in 1.19.2.

@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
