This happens on bedrock even Sometimes its just the sound delayed other times it could be 10 seconds or more of random fall damage. Painful when moving down a mountain and the fall damage happens all at once  over multiple 4 blocks drops

I can confirm that this does NOT happen with a Vanilla server that I just freshly set up. Interestingly, it did work many times on a server I play on that used to be on Bukkit 1.16.5 and still works now that it is on Fabric 1.17.1.

Comment by [Mod] Avoma [ 04/Oct/21 ]

In regards to the above comment, I've done some further investigating regarding this issue and it appears that this problem doesn't exist in multiplayer server worlds, but does exist in multiplayer LAN and singleplayer worlds. I'm not exactly sure why this is the case, but I've provided some attachments that demonstrate this behavior.

Comment by Guerau Garrigós [ 05/Dec/19 ]

Maybe it's that when you log out of a game the information of the fall is not saved and/or used when you log back in. So then the game registers it as a fall from that fall level.

If you can see that, that's enough for one version. Many people have seen it before in other versions and there's not a big chance that it was fixed accidentally.

Comment by Block twenty-eight [ 09/Jun/16 ]

Ok, did that, thanks for mentioning.
Just something regarding the description of the bug: "This basically makes fall traps useless on PvP servers." is now actually useless since this ticket now is about a singleplayer bug.

And: Can confirm this bug for 1.10.

Comment by [Mod] Michael Wobst [ 09/Jun/16 ]

null: Block twenty-eight already explained it very well how to reproduce.

Block twenty-eight: you can remove that "EDIT: Irrelevant as I misunderstood the ticket. I'm sorry for that." from your latest post, as you totally understood the issue, and explained very well on how to reproduce it.

Comment by null (Inactive) [ 08/Jun/16 ]

Still cannot reproduce in 1.10:

  • Integrated singleplayer server
  • Resistance IV (4), Protection IV (4) Feather Falling IV (4) Diamond Boots
  • Falling from 250 blocks: 3 HP left (1.5 hearts)
  • Falling from 250 blocks, and relogging after falling ~150 blocks: 3 HP left (1.5 hearts)

miwob Could you please provide a list of steps to reproduce?

Comment by [Mod] Ezekiel (ezfe) [ 08/Jun/16 ]

This issue is only currently present in single player, and as such I have reopened the ticket and edited it accordingly

Comment by [Mod] Michael Wobst [ 08/Jun/16 ]

No, it's not about multiplayer. Also it's still an issue in 1.10. So why exactly has this ticket been marked as fixed?
Maybe the description should be reworked a bit since it's mainly an issue for map makers who intend to integrate fall traps into their singleplayer maps

Comment by Kumasasa [ 06/May/16 ]

Block28: This ticket is about multiplayer, see the description.

Comment by Block twenty-eight [ 06/May/16 ]

At least I can still confirm it in Singpleplayer, however I didn't test it in Multiplayer. (Version 1.9.3 Pre-Release)
Steps to reproduce:
1. Build some sort of high tower.
2. Fly/Climb on top of that tower. Then go into Survival Mode.
3. Jump down once to test if you would die when you hit the ground.
4. If you die, jump down again from top of the tower and log out right before you hit the ground.
5. Log back into the world.
6. See how you don't take any fall damage.

Comment by Kumasasa [ 06/May/16 ]

miwob, when you still can confirm this issue, please provide steps to reproduce.

Comment by null (Inactive) [ 05/May/16 ]

Cannot reproduce on 1.9.3-pre3...

  • Non-integrated MP server
  • PvP enabled in server.properties
  • Resistance IV, Feather Falling VI
  • Fall from 350 blocks, half a heart left
  • Fall from 350 blocks, logout after falling ~150 blocks, still half a heart left

Can anyone confirm?

Comment by [Mod] Michael Wobst [ 16/Mar/16 ]

No, it's not fixed at all in 1.9.1-pre3

Comment by Kumasasa [ 16/Mar/16 ]

Can anyone confirm the fix in 1.9.1-pre3 ?

Comment by James (inactive) [ 15/Mar/16 ]

Appears to be fixed in 1.9.1-pre3.

Testing results:

  • Resistance IV
  • Feather Falling IV, Protection IV diamond boots
  • Falling 250m: 3hp left
  • Falling 200m: 6hp left
  • Falling 250m, relogging at 200m (after falling 50m): 3hp left
Comment by Marcono1234 [ 28/Feb/16 ]

Block28 In 1.8.9 VillagerGolems are not aggressive after reopening the world as well

Comment by Block twenty-eight [ 26/Feb/16 ]

I can still confirm this bug for the 1.9 Pre-Release 4. Maybe this is also the reason why Villager Golems aren't aggressive anymore after relogging (at least in Singleplayer).

Comment by [Mod] Michael Wobst [ 18/Feb/16 ]

Excellent work as always, Marcono1234. :thumbs up:

Comment by Marcono1234 [ 18/Feb/16 ]

Please link to this comment in the description of the report.

The following is based on decompiled version of Minecraft 1.8 using MCP. All method and class names are the names used in the decompiled version.

The way fall damage is handled while the respawn resistance is active is kind of strange. There are two requirements that have to be met to apply fall damage after the player logged in:

  • The server must not be an integrated server
  • PvP must be enabled

This seems not intended to me. To fix this the public boolean attackEntityFrom(DamageSource source, float amount) method of the net.minecraft.entity.player.EntityPlayerMP class needs to be modified.

/**
 * Called when the entity is attacked.
 */
public boolean attackEntityFrom(DamageSource source, float amount)
{
    if (this.func_180431_b(source))
    {
        return false;
    }
    else
    {
        // Changed this
        //boolean var3 = this.mcServer.isDedicatedServer() && this.func_175400_cq() && "fall".equals(source.damageType);
        //if (!var3 && this.respawnInvulnerabilityTicks > 0 && source != DamageSource.outOfWorld)
        if (source != DamageSource.fall && source != DamageSource.outOfWorld && this.respawnInvulnerabilityTicks > 0)
        {
            return false;
        }
        else
        {
            //...
        }
    }
}
Comment by [Mod] Michael Wobst [ 18/Feb/16 ]

Well, it works as expected in SMP, so there's inconsistency between SSP and SMP. Also as mentioned, if this was intended behavior, you could completely remove fall-damage from the game since you can cheat around with ease. i.e. fall-damage gets rendered completely meaningless.

Comment by Marcono1234 [ 17/Feb/16 ]

That is very likely caused by the resistance against all damage after logging in, see my comment

Comment by [Mod] Michael Wobst [ 17/Feb/16 ]

What test setup? It's explained very well in the description. Log out/exit just before you hit the ground. Log back in and you won't get any fall damage.

Comment by Marcono1234 [ 17/Feb/16 ]

miwob please describe your test setup

Comment by [Mod] redstonehelper [ 24/Dec/15 ]

People who have recently reproduced this: Please describe your test setup.

Comment by Marcono1234 [ 23/Dec/15 ]

Sorry for the confusion and please remove the note

Comment by Marcono1234 [ 23/Dec/15 ]

Cannot confirm for 15w51b
The fact that the player takes no damage is because he is always resistent against any kind of damage for the first seconds after entering a world.

To see that the fall damage is correct you can do this:

  1. Give yourself resistance
    /effect @p resistance 10000 3 true
    
  2. Place a block at the height where you would survive the fall
    /setblock ~ ~103 ~ stone
    
  3. Switch to Survival mode
  4. Teleport yourself up
    /tp ~2 ~115 ~
    
  5. Once you passed the stone block leave the world
  6. Open the world again
    You should die from the fall damage, this means the damage was not calculated from where you logged out / in

This seems to not only affect FallDistance but also Motion. This can be seen when having a command block clock that teleports the player constantly upwards (for example /tp @p ~ ~1 ~), because of MC-79938 the player appears to "bounce", however when reopening the world the player is at a higher position than before.

Confirmed for 1.8.9 and 15w51b.

Still in 1.8.1

Comment by [Mod] Michael Wobst [ 29/Jul/14 ]

NOTE: this issue only appears in singleplayer. When playing in multiplayer, everything works as expected.

Comment by Jochem Kuijpers [ 06/Jul/14 ]

Still exists in 1.7.10 single player.

In multiplayer, a player will fall to his death but in single player he will land without falldamage.

Comment by Brian van den Berg [ 29/Apr/14 ]

I think the current code rewrites are going to seperate certain kinds of damage and not into 1 category. It's just an guess, but that would make it possible to make invulnerability not count on fall damage.

Comment by Nicholas Chard [ 19/Dec/13 ]

I think that the 3 seconds of invulnerability needs to be kept, except for fall damage. Or have a very large invisible health shield upon login, which would only be ignored by fall damage.

@ezekielelin
bljat already has put them up, he just hasn't taken off the fix version, probably because it was confirmed in multiplayer in 1.4.3 (but I haven't tested it yet, it could still be a bug in multiplayer)

Comment by Tails [ 25/Jun/13 ]

Reopened as this is still an issue in 1.6 Singeplayer.

Comment by Pizzacheese4 [ 25/Jun/13 ]

I think a good fix would be to give you invulnerability only if you are on the ground, but if you were in the air, you dont get it. Just an idea, dont get mad if it is a bad one.

also, this bug applies to singleplayer in 1.5.2, too

Comment by WolfieMario [ 17/Mar/13 ]

Does this mean you no longer get invulnerability upon login? Because the 2-5 seconds it takes to load a server texture would become brutal. I hope this fix only applies to fall damage.

Comment by [Mojang] Grum (Erik Broes) [ 25/Oct/12 ]

No, the data is stored and loaded correctly, the only reason you do not get damage is because you get 3 seconds of invulnerability when you login. I spend a good 45 minutes with a debugger jumping of a pole seeing what happened

Comment by [Mod] Michael Wobst [ 25/Oct/12 ]

Yes, that is the point. Falldamage gets re-calculated after logging out/logging in. So if you logg out if you're three or four blocks above the ground, you won't get any fall damage at all when logging back in! Not sure if Grum misunderstood this issue.
This applies to single- as well as multiplayer, btw.

Comment by SinZ [ 25/Oct/12 ]

Grum, the bug is that fall-damage gets re-calculated when you login.

Comment by [Mojang] Grum (Erik Broes) [ 24/Oct/12 ]

Falldamage can occur on a remote server with pvp turned on.
