While moving, Steve 'sticks' and can't keep going.

Only happens to me when I walk into a non-solid block, like an anvil or a fence.

Can you please press F3 + C while in-game to force a crash and attach the resulting crash report here ?

Possibly you run into the invisible block issue ?
Can you leave and reenter the game when this issue happenes next ? If there's a block where no block was prior leaving, then it's the invisible block phenomenon.

I was going to report a similar issue that I can reproduce easily. The player gets stuck in corners of chests when walking towards the sides of chests at an angle. Most of the time the player gets stuck and this jerky movement occurs. I didn't know that it occurs when colliding with other objects too.

It's occurred when moving down hallways or even exploring outdoors, where I have not placed any blocks. I'm exploring now to try to reproduce it for that crash report thing, but I think I've gone out and come in again to still be stuck, so it doesn't seem like the invisible block thing. Once I backed up, placed a block where I'd been getting stuck, dug it out, and could walk through the spot without trouble, but that spot was a consistent problem, where other times it hasn't been.

I can confirm this issue. I have a hallway that has slabs on the ground and sometimes if I hit them just right (usually the corner) I get stuck on it and my few vibrates like it's trying to move there and cannot.

Nothing like trying to find a problem to make it not happen. I've finally gotten it happening again, but F3+C doesn't seem to do anything. I'm running vanilla, survival mode, on a PC, I've changed some of the controls but F3 isn't one you can change. Why do I always get the problems that make techies say, "That shouldn't happen!"

same here F3+C does NOTHING AT ALL! annoying because i have this bug LOTS and would like to help - STUPID F3+C!

This time, I was tunneling down a stairway into the deeps. Turned around to climb up again, and I can't jump. Moving forward made me jiggle forward and back instead of the not moving forward and maybe sliding sideways that I should do when walking forward with a block in front of me. I turned and went back, then came past the spot again with no problem. It doesn't stick anymore. There are no blocks I've placed here, just natural stone.

Forgot to say that you have to press F3 + C for at least 10 seconds.
Sorry.

Manually crashed at a spot where glitch happened. This was outdoors, next to a grass block. Well away from anything I'd built. After crashing I went back in and was still stuck there. No new blocks, so no invisible block. The jiggling is somewhat like what you used to get if you tried jumping with something right overhead.

It happenes with me on all blocks, solid or not.

Affects 1.4.7

Happens still in 1.5

Still in 1.5.1

I can confirm with a door slamming in your face. Do those of you who have this bug see it when just walking around solid blocks?

Yeah, walking outside on grass, walking in a tunnel carved into stone, all kinds of places.

I've had it happen when jumping into a fence or into tight quarters (like in a mine).

Still happens in 1.6.2

Still in 1.7.2

Is this still a concern in the latest Minecraft version 14w04b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Yes, this still affects 14w08a (tested with a boat when pushing it on the ground while moving.)

Also exists in 14w11b.

For me, this most often happens on block edges, not corners. Mostly on stone blocks while mining.

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Happened earlier this week in 1.8, wasn't in the test environment. I'll check this weekend. I'm on a new computer, too, which has helped some issues.

I think this ticket got superseded by MC-68080

This is not lag. Stuff is moving in its normal way, I just get snagged.

Is this still an issue in the current Minecraft Snapshot 15w47c or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

I've seen this happen in current versions (I'm not sure of specific ones, though). It's easiest to reproduce if you're instant-mining with Haste 2 and Efficiency 5 (or, Efficiency 3 in the nether).

I think there's a pretty easy way to fix that, and that is to resend the block the player is trying to move into (a Set Block packet) whenever a player tries to move through a solid block. That would fix the desync that is probably happening.

I believe this bug happens because the client thinks it broke a block, but the server ignored or rejected the block breaking. The client then thinks that the block is air, but the server thinks it's a solid block, so when the client tries to move through it the movement is rejected. You can see that this is a desync because trying to interact with that air block causes it to become a solid block (either by right-clicking it or by placing a block "in" it).

Actually duplicate of MC-5694
