[MCPE-13758] Block hitboxes are generally too big

Summary:
Various blocks have hitboxes which are too large, which means that they can prohibit access to other blocks.

Steps to Reproduce:

Punch a single hole in the ground
Place a chest in the hole
Place a standing sign or a fence gate over the chest
Try and open the chest

Observed Results:
The chest cannot be accessed because the hitbox for the sign and/or the fence gate it that of a full sized block.

Expected Results:
You hitboxes should be smaller for certain blocks, listed below.

Screenshots/Videos attached: Yes (please see attached test world too)

Notes:
These blocks have hitboxes which are too large, and have been compared to the Java version:
Updated for 1.5.0.1 beta:

Piston Arm

These blocks have now had their hitboxes fixed:

Standing Sign
Anvil
Fence Gate
Brewing stand (top part only)
Single Glass Pane
Single Iron Bar
Fully grown crops (eg Carrots)

Please see attached test world for working examples of these

nb. The following blocks also have hitboxes which I consider too large, but may be working as intended as they have the same hitboxes as the latest Java version: Hopper, string, cauldron, bed, cobweb.

Here's another example: This chest cannot be opened, as the gate's hitbox gets in the way.

0.14.3 Case in point: This Chest cannot be opened because the sign's hitbox is too large.

Relates to MCPE-1813

Updated affected versions. Another example of hitboxes being too large, in this case, string: (MCPE-17457)

Checked all the items in the list again in 1.0.0

SuperGeniusZeb 2016-12-30T22:53:06Z

Revised the title to reflect the fact this report is referring to block hitboxes specifically, not other hitboxes, like entity hitboxes for example. ~~Also edited the description to reflect the fact that this bug has been fixed for fences due to the fix for MCPE-1813 back in 0.17.0.2.~~ EDIT: Turns out that only the collision box for fences has been fixed... not the hitbox.

This bug is a little too vague so it's making it hard for our teams to repro and fix. Can you please explain more about which hitboxes are too large & how it affects the game? Some of these may be by design so as much detail you can give, the better. Thanks so much! 🙂

@@unknown:
I've updated the ticket description which should hopefully make it easier to reproduce the issue, and I've emphasised the blocks that break parity with the Java version.
Also, please find attached a copy of the test world which should help to see the problem in a working situation.

Added image comparing the new glass pane shape hitbox, compared to the Java edition:
(Same principle applies to iron bars)

More hitboxes have been fixed in 1.2 beta build 4. I've Updated the description with the remaining hitboxes that are still too large.

These are:

Yes, please make hitboxes for windows 10 users a lot smaller however dont make hitboxes for the pe players too small as it is an issue of handibility and control

bemoty 2017-09-02T01:19:04Z

Iron bars and glass panes fixed in 1.2.0.25.

Capopanzone 2017-09-02T13:13:28Z

Confirmed for 1.2.0.25:

Chest/trapped chest/ender chest hitbox is too big - it wasn't updated when they added 3D chests
Cactus and soul sand hitboxes are too low
Sugar canes hitbox is too big
Grass path and farmland hitboxes are too high

Caleb Martin 2017-09-06T04:29:08Z

Confirmed in 1.2.0.25 for several crops that still have hitboxes that are too big – Carrots, Beetroot, Potato, Wheat, and Sugarcane.

On the other hand, Nether Wart hitboxes are too small – they have the newly planted size hitbox even at fully grown.

Update: Still in 1.2.0.31

[Mojang] Mega_Spud (Jay) 2017-09-18T06:12:27Z

Please make a new ticket for any new hitbox related bugs, so they can be tracked and fixed more easily.

Is this the reason that AFK fishing farm is not working? D:

Caleb Martin 2017-10-19T02:25:31Z

All the crop hitboxes that I noticed before seem to have been fixed in 1.2.3.6.

[Mojang] Mega_Spud (Jay) 2018-05-14T11:37:36Z

Updated the description with the latest details.

Henry Markle 2018-07-07T03:11:05Z

The chest's hitbox is still too big.

Jonny Tarr 2019-06-17T13:41:47Z

Hopper hitbox is so annoying. You can see past its funnel, but you can’t click anything behind it. I’d put this near the top of the list of small changes that would reduce frustration by a huge amount.

Jonny Tarr 2019-06-17T13:50:00Z

Note: At some point the hopper hitbox was changed / fixed for Java edition. See: MC-6435. Be great to see the same fix applied to Bedrock edition.

WildtheGamer1 2019-06-19T03:32:59Z

Can confirm that hitboxes for grass paths, soul sand, and hoppers are still too big in 1.12.0.12

[Mojang] Mega_Spud (Jay) 2019-06-19T10:34:08Z

To make this easier to track, please create a new ticket for each hitbox that is not working as designed, where this adversely affects gameplay (for instance hoppers having a large hitbox means that chests underneath cannot be accessed).

Jonny Tarr 2019-10-27T19:14:25Z

For reference, a ticket for the hopper hit box issue now exists at: https://bugs.mojang.com/browse/MCPE-47541
