 Description   

So when you have several hoppers next to each other in a sorter... Items tempt to go flying... Because if the item doesnt fit in there it jumps ump and maybe skips it good place. So this makes sorting machines only work at 95% can you guys fix that?

Resolving to MC-1720.

I have a lavablade-and-player-attack mob grinder with a hopper collecting the loot, and it keeps making the experience orbs bounce up into the lava. I think at least 2/3 of the experience is getting lost this way.

Made one

It also furnaces things for you

If you want a stable item sorter, It's way easier now. You don't have to use water, just use hoppers instead of water. Just search for it on youtube/google

Appears worse in 13w09c than before. My sorter is missing huge amounts of items now, compared to the previous snapshots.

This is a regression for items getting stuck inside transparent blocks, when items are inside those, they fly out, and when items are on top, they bounce, even if nothing occupies the way for the item to fall into the hopper, you can occasionally see the item bouncing away from the hopper before disappearing.

Comment by Jesper the End [ 23/Jan/13 ]

Annoying indeed, but it probably works as intended. One weird thing I have noticed though, is that xp also bounces when it is on a hopper.

Comment by Corgano Wade [ 21/Jan/13 ]

It's annoying as hell! please PLEASE fix

Comment by Dragnoz [ 17/Jan/13 ]

I do agree with you though and I did add my vote...

Comment by Thimo Franken [ 17/Jan/13 ]

That's nonsense... It makes every thing really unreliable. So it shouldn't be intented behaviour.

Comment by Dragnoz [ 17/Jan/13 ]

I think thats why its called a "Hopper"

Comment by Thimo Franken [ 12/Jan/13 ]

Thanks Tails

Comment by Tails [ 11/Jan/13 ]

Confirmed in 13w02b.

Comment by Thimo Franken [ 09/Jan/13 ]

Yeah but i finally got a proper way of tiling the sorters as i shown in my video... but because of this behaviour it aint possible to get that working 100 percent

Comment by Ultimate Omicron [ 08/Jan/13 ]

For now you can use detours and space between the hoppers. Are you using water to transport the items?

Comment by Thimo Franken [ 08/Jan/13 ]

Yeah well this behaviour makes it impossible to have a 100% reliable tileable item sorting machine D: So mojang please improve our abilities and remove that hitbox thing

Comment by Ultimate Omicron [ 08/Jan/13 ]

That happens because the hopper has a composite hitbox. The item tries to fall on the carved middle, but can't occupy that space due to the new item ejection code so it jumps. Similar behavior can be seen with the lower step of a stair block.

Comment by Thimo Franken [ 08/Jan/13 ]

What do you mean?

Comment by C.J. Wijtmans [ 08/Jan/13 ]

at which time mark can i find it?

Comment by Thimo Franken [ 08/Jan/13 ]

Watch my video on automatic tileable sorting machine:
http://www.youtube.com/watch?v=itzlwHLtCbc
Its a great machine... But if a hopper has like cobble in it and dirt tries to go in. It checks in like 1 tick and if it ain't fitting in there it litterally JUMPS up and keeps the velocity it was going in. Wich may screw it up becus the next hopper maybe have the right item in where it fits in. But then it jumps over it because of that. Hope you understand

Comment by C.J. Wijtmans [ 08/Jan/13 ]

Havent noticed this behavior are you sure its not jumping on a stair or half slab? Which is a different bug.
