On normal or hard difficulty the right or left head of the wither will only look at the player, but the player will be shot by the other side head of the wither. On easy mode one of the side heads of the wither will still look at the player, but no Wither skulls will be shot at the player.
This bug I reported contradicts the bug reported in MCPE-17446 whichh reported a bug that the Wither does not use all three heads when shooting because the bug I reported only applies to players in survival mode
In version 1.21.51.24, the bug in MCPE-32826 was fixed which stated that the Wither head was not looking at the targeted mob or player properly, but this did not fix the bug I reported. I tried playing the Beta version 1.21.51.24 and compared it to the release version 1.21.41.01 and the difference is that the Wither's side head in Beta 1.21.51.24 follows the main head's direction more and in 1.21.41.01, the side head looks more like it's looking at me although the way it looks is a bit weird. But in both versions one of the Wither's side heads still shoots at me
Wither Skull
Steps to Reproduce:
[Step 1]create a flat empty world with no mobs spawning. Don't forget to activate the education edition and also set the difficulty to easy because the wither's side head will not shoot at you on easy difficulty
[Step 2] after the world is created, then spawn some snow_golems
[Step 3] run these 2 commands
/effect @e[type=snow_golem] regeneration infinite 225
/effect @e[type=snow_golem] health_boost infinite 225
[Step 3] run this command so you can fly in survival mode
/ability @s mayfly true
(make sure education edition is active)
[Step 4] summon a wither
/Summon Wither
/give @s wither_spawn_egg 64
[Step 5] make sure the wither attacks the snow_golem
[Step 6] set the gamemode to survival
/gamemode s @p
[Step 7] Try to notice that the wither's side head right or left will look at you and the middle head and the other side head will look at snow_golem
[Step 8] from easy difficulty, increase to normal or hard, then the side head of the wither that looks at snow_golem will shoot at you, but not at you and the one looking at me is the other side head
/difficulty n
/difficulty h
Observed Results:
• On easy difficulty, one of the side heads of the wither will look at me, but not shoot at me
• One of the side heads of the wither will shoot Wither Skull at another mob, But the shot is thrown from the middle head
• On normal or hard difficulty, the Wither Skull that is shot at the player is shot from the side head that looks at the target mob wither
Expected Results:
• The Wither Skull is shot from the head that looks at the mob
• Wither's side head don't just target the player only
• Wither better if attacking more than one mob like in Minecraft java
Notes:
• It turns out that the Wither in Minecraft Bedrock can attack more than one mob like in Minecraft Java, but this bug causes the Wither's side head to only attack players in survival mode
• Try reproducing this bug in a multiplayer game with friends your play because I haven't tried to reproduce this bug in multiplayer game.
• The main wither head only looks forward and sometimes looks towards the target player or entity
• This bug can occur in the current version (1.21.41.01) and Beta version 1.21.50 and above. but this bug is more better visible in version 1.21.41 because in Beta version 1.21.50.22, the bug in issue MCPE-32826 has been fixed.
• If all players are in creative mode, the two side heads only look at their target mob according to the version of Minecraft I play. In version 1.21.50 it will follow the main head (due to the MCPE-32826 fix) and in version 1.21.41.01 the side head will be more free even though the wither only attacks one mob because there are no players in survival mode (due to the MCPE-32826 fix that has not been applied)
• Don't let the wither get damaged by you because it will cause this bug to fail to reproduce and other bugs to occur. (I reported this other bug in MCPE-187944)
