 Description   

The bug

Sometimes, when you walk over the corner of a pool of lava, it will deal a heart of damage to you.

How to reproduce:

  1. Lay out a ring of blocks with a 2x2 lava hole in the middle
  2. Stand exactly in the middle on the outer edge of one side of the ring
  3. Angle your camera to exactly the middle of the inner edge of the ring on either side left or right
  4. Move in a straight line forwards while in survival mode (notice you will not "fall" down, but still take damage)

For a more exact setup, use a command block with the following command:

tp @p ~-1.5 ~0.5 ~0.5 -153.3 36.0

I am also unable to reproduce this in 20w06a (just tested 1.15.2 to be certain). Will mark as fixed.

Comment by [Helper] Jack McKalling [ 05/Feb/20 ]

Cannot reproduce in 20w06a. Probably fixed

Affects 1.13-pre6

Comment by Fabian Röling [ 21/Aug/16 ]

Command for reproduction: teleport @p ~-.5 ~.5 ~.3 45 in a command block, one block further to negative X and positive Z lava, all four blocks around the lava is a solid block.

To reproduce, you must sprint over the corner of the lava at the right angle; you will not fall in but take half a heart of damage.

Comment by Fabian Röling [ 29/Jun/16 ]

I think the reason why this happens is the same as why you can sprint over a gap of one block length: If you are behind the top half of a block, you go up on it (like on slabs or from slab to block). This also happens while falling. If you sprint over a one block wide gap, you don't fall enough to be under that 0,5 blocks mark, so you go up again. The same probably happens here: You can go down enough to be in the lava, but high enough to go up again. The real bug is that you don't get the usual 300+2x ticks of fire (in this case 300 or 302) afterwards.

Comment by Anon Ymus [ 24/Jun/16 ]

I think only related because simply walking over lava shouldn't damage you.

Comment by Kumasasa [ 23/Jun/16 ]

Isn't this duplicating MC-1133 ?

Comment by null (Inactive) [ 23/Jun/16 ]

Cannot reproduce in 1.10.2. However, you can get burnt when there is soul sand in the corner

Comment by [Mod] CubeTheThird [ 02/Feb/16 ]

Was able to reproduce it in 16w04a

Comment by [Mod] Michael Wobst [ 02/Feb/16 ]

Tried to reproduce it once again with 16w04a this time, and wasn't able to reproduce it this time, too.
Can someone else confirm this being fixed?

Comment by [Mod] Michael Wobst [ 31/Oct/15 ]

I tried really hard to reproduce it, but wasnt able to. Probably should be closing this issue considering its last update time.

Comment by Hartspoon [ 03/Mar/14 ]

Still a concern in 14w08a.

Comment by [Mod] CubeTheThird [ 26/Sep/13 ]

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Comment by Rafael Ristovski [ 25/Apr/13 ]

I think this was a feature added when the particles coming off of lava and the plopping sound were added.

Comment by Tails [ 26/Dec/12 ]

Confirmed in 1.4.6 and reproducible with any kind of block. As seen in the screenshot standing at this angle and walking forward will damage you without falling into lava.

Comment by Anon Ymus [ 24/Nov/12 ]

Is there soulsand at the corner?
