Created Issue:
Attribute generic.movementSpeed doesn't work when using /summon
I have been trying to make an EnderDragon entity that will stay still. At first, I tried to use a ghast as an analog. I put in a command to summon a ghast that has the attribute generic.movementSpeed with a base value of 0. The ghast was able to move.
After trying to get the command right and testing with a bat, I figured that generic.movementSpeed doesn't apply to flying mobs, so, I decided to make an Ender Dragon riding a chicken that has that same attribute with the same base value.
I first tried to make a chicken with that attribute. I failed. I looked up a video on YouTube (http://www.youtube.com/watch?v=NekyPChWtNU), and tried to use the commands that the author posted in the description of the video to make the chicken. I still failed. I then used the command from the video. It didn't work.
I have done further testing. I spawned a skeleton with the command from the video, and one with /summon Skeleton. Their speeds were identical.To replicate this bug for yourself, during the day, build a small ceiling two blocks above the ground. Then, five blocks away from that ceiling, do:
/summon Skeleton ~ ~2 ~ {Attributes:[
{Name:generic.movementSpeed,Base:0.001}]}
Then, do:
/summon Skeleton
Compare the speeds of the two skeletons. They should be identical. Seeing as the default movement speed for living entities is .7, then the second skeleton should be 70 times faster than the first one.

(Moving this comment to MC-40949)
generic.movement.speed also still not working.
@ Mods: Is there another bugpost regarding the attributes like generic.movementSpeed, or is this here with the title about effects the host for basically both issues?
If so, could the title be maybe altered so it's clear that it also applies to those attributes, not only potion effects?
I'm glad I found this bugpost regardless 😸
I tested this command in 15w51b, without success (Bat is still moving normally fast):
summon Bat ~ ~ ~ {Tags:[LLPartShow,PartBat],Attributes:[{Name:generic.movementSpeed,Base:0.05}],Invulnerable:1,Silent:1,ActiveEffects:[{Id:14,Amplifier:0,Duration:630720000,ShowParticles:0b}]}-
Edit: I tested Marcono1234's workaround, and it seems to work on Cows, but apparently not on Bats }=/
Kind regards, Meri
@Meri Diana The movementSpeed attribute works for most mobs; it's the flying/swimming ones that are unaffected by any speed modifiers (MC-40949 covers that). For this report, the "ActiveEffects" tag applying speed or slowness does nothing for any mob, with generic.movementSpeed being the more precise work-around.
isn't this a duplicate of MC-40949, instead of relates to?
Why is this being postponed? This is a huge bug. It allows players to walk at normal speed while jumping for the entire duration of slowness effect.
Torabi, common-sense physics dictates that forward moment should be preserved while jumping, but this bug allows momentum to be gained while in the air. Either you don't understand simple physics, or haven't looked at the bug. It's as much a bug as MC-40949
Mojang, how is this in the game for so long? Players shouldn't be able to negate slowness just by starting to jump.

Can reproduce in 1.16.201. Also reported on Java as MC-40949, which targets flying mobs in general.
Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.8 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.
Hmmm... Compare to
MC-33110andMC-44849.This ticket is incomplete without the requested information, no response has been received within a reasonable time and we are assuming the issue has been resolved. If you are still experiencing this issue, we can reopen it at your request.
Very old ticket issue, but can confirm that ender dragons, ghasts, and bats do not obey the generic.movementSpeed attribute for MC version 15w40b using commands per below (replacing Ghast for the other two entitiy names)
summon Ghast ~ ~ ~ {Attributes:[{Name:"generic.movementSpeed",Base:0.001}]}Variants for the base value (0.1, etc) have been tried as well with no success or notice in movement speed differences.
Edit: Apparently I dont understand site formatting mechanics even with the use of the help.
That's intended, movementSpeed is about walking, bats, ghasts, withers, squid and enderdragons don't walk, they fly/swim
flying or swimming is still a movement, which is what the attribute name implies it should modify - movement speeds, it isn't titled walkingSpeed, so I do not see this as intended.
Reopened and gave the ticket to Anthoni Wiese. Please update the list of affected versions, title and description to accurately reflect the issue as it in current versions.
True, same for speed/slowness potion effect then as well (which I saw get resolved by that reason if I remember correctly)
Confirmed for 15w51b/latest 1.9 Snapshot.
generic.movementSpeed still not working.
I tested this command in 15w51b, without success (Bat is still moving normally fast):
summon Bat ~ ~ ~ {Tags:[LLPartShow,PartBat],Attributes:[{Name:generic.movementSpeed,Base:0.05}],Invulnerable:1,Silent:1,ActiveEffects:[{Id:14,Amplifier:0,Duration:630720000,ShowParticles:0b}]}Kind regards, Meri
I can confirm it still not working in 15w51b, added it to the affected versions list. I am still keeping tabs on this particular report.
A slight change to the bat's hard-coded movement speed multiplier (class EntityBat, method updateAITasks) seemed to work pretty well. Original section via MCP:
Modified:
While upon instantiation its default would be set to the original multiplier (method applyEntityAttributes):
this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.10000000149011612D);For ghasts, I did the same (class EntityGhast, method onUpdateMoveHelper). Original:
Modified:
Attribute instantiation (method applyEntityAttributes):
this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.1D);Both seemed to work fine with no obvious issues. Able to change their movementSpeed attribute and see the changes take place (such as a value of 0.0 preventing movement), and the /effect command can successfully modify their movementSpeed.
Can confirm this issue still exists in 16w03a and 16w04a snapshots. Updated the versions list for this, and fixed an issue in the description saying to compare the skeletons instead of ghasts.
Confirmed for pre-2.
Posting to confirm for ghasts and bats in 1.11.2. Neither movementSpeed or speed/slowness effect/potions will alter their movement speeds:
/summon bat ~ ~1 ~ {Attributes:[{Name:generic.movementSpeed,Base:0.001}]} /summon bat ~ ~1 ~ {ActiveEffects:[{Id:2,Amplifier:5,Duration:19980,ShowParticles:0b}]} /summon ghast ~ ~1 ~ {Attributes:[{Name:generic.movementSpeed,Base:0.001}]} /summon ghast ~ ~1 ~ {ActiveEffects:[{Id:2,Amplifier:5,Duration:19980,ShowParticles:0b}]}Oddly, it seems to work for blazes, but only when they're "walking" (touching the ground)
Confirmed for 17w13a (and 1.12-pre3).
Confirmed for 1.12-pre7 (already added)
Anthoni Wiese, you don't have to comment when you add affected version(s) yourself
I may not need to SunCat but not everyone looks at the activity logs, or sees the full version list and may repeat whats already been added.

Avoma's comment regarding allays is only partially true: allays, bees, withers, and parrots have a flying_speed attribute that controls their flying speed. Expected is that ghasts, bats, phantoms, ender dragons, blazes
and players (creative/spectator) also have that attribute, as they can all fly. Either that, or the attributes should be merged, which makes speed/slowness also affect the mobs with the attribute already.
Can confirm in 1.21.4.
