Confirmed. Sprinting is broken.

Can confirm it as well. Sprinting is definately broken.

The same problem occurs with speed potions

Donald Arno 2013-05-23T16:37:57Z

Sprint-jumping on the other hand works.

Created a simple test rig to show the problem; A line of repeaters set to maximum delay triggered by a tripwire at the start, with another bank of repeaters set to latch the first line when the finishing tripwire is triggered. Dirt block shows where the light stopped when sprinting or walking, birch block shows where the line stopped when sprint-jumping the whole length. Will test again after loading 13w19a for comparison.

Comparison picture after testing in 13w19a. Far block is walking (same position as the dirt block from other picture), near block is sprint-jumping (Close to same position as birch block in other picture), middle block is regular sprinting.

Further testing with Speed II effect active showed same results as walking and normal sprinting in 13w21a.

I can confirm this in survival/adventure mode as well.

Confirmed. very annoying specially in my parkour map ruins it all.

This also applies to the Slowness effect.

I can confirm that you speed up while in mid-air if you jump while running.

Mike Kolbe 2013-05-24T00:07:33Z

Besides sprinting, swiftness potions do not seem to work either

Jonathen Stacy 2013-05-24T04:22:38Z

Speed is not working for beacons in survival unless jumping while sprinting.

Kaden Warner 2013-05-24T12:48:13Z

Confirmed

Tomas Watchorn 2013-05-25T07:00:17Z

I can confirm that slowness effects do not slow you down and instead keep you at walking speed

Ed Kelly 2013-05-27T20:31:25Z

I think that this has to do with the new "Attribute System" that the snapshot post on mojang.com mentions.

My server spit out this message when I tried to sprint the first time on 21a:

2013-05-26 16:55:45 [WARNING] Ignoring unknown attribute 'Speed'

And... I just realized that this issue is resolved already. :/
