I've annotated the code block for understanding, so check it out
In 1.20.4
Can confirm in 1.21.1
The new way to trigger this bug seems different from the previous methods. Please check this ticket:
MC-276926By the way, as what I mentioned in that ticket, this bug may be related to an old bug which hasn't been fixed for several years. I think the old bug has been reported, but I can't find it in Mojira, please help find it.
Can confirm in 1.21.2 pre 2
@BugTracker I think that ticket doesn't fully describe the bug. If there isn't any ticket fully describes, I will modify this ticket and add some details.
Can confirm in 24w44a
I tested again and found MC-28289 can describe this issue.
I originally thought that the bug on the server that caused the item error was also due to this. But vanilla didn't seem to have the problem with that server
Can we close the old ticket and reopen this one? Because the old one didn't mention that the impact of the bug on the behaviours more than combat. The community consensus of that ticket is also just about combat.
In addition, the melee attack charging does not reset in time
Thanks
Although the ticket was marked as a "community consensus", I still need to explain more about the impact of the bug on the game
Why should this bug be fixed?:
This ticket can be closed because MC-28289 can describe how the problem can be caused again
I tested and checked out the src, finally found out the solution.
The attributes of living entites only refresh when entities' mob effects change or by tick.
So we can refresh players' attributes when they change their selected item.
Can confirm in 24w45a
Can confirm in 25w04a
I tested with this command:
/give @s minecraft:diamond_sword[minecraft:blocks_attacks={block_delay_seconds:0.0,disable_cooldown_scale:0.0,damage_reductions:[
{base:0.0,factor:0.5}],block_sound:"minecraft:entity.zombie.attack_iron_door"}]
It works fine. Are you mistaken?
