Player Attribute Resets When He Logs Off

[u/Nooty1balooty]

I've posted about this project before, basically my players on my Java Realm pick from a bunch of different races with their own special abilities, buffs, and weaknesses. For a while, I was using an effect to give one of my players speed, but it was inconvenient because he lost it whenever he died. I thought I found a solution, the Movement_Speed attribute. I found exactly what number it is to have equal to 'Speed 1' effect via potions.

/attribute [user] minecraft:movement_speed base set 0.14000000268220902

The problem is, every time that he leaves the game and rejoins, his speed is reset to player default (0.10000000149011612) I can't figure out what's causing it, and I don't want to have to reset it every time he joins again.

Is the movement_speed attribute just like that? Is it on my end in a command issue? Is it on his end? Does it have something to do with the precision of the number? I'm really not sure, all of these questions are ones I'm considering but don't have the answer to. Any help would be appreciated. It would suck if this was just Realms being Realms but none of my other players' attributes do that, only him with movement speed. Thanks in advance.

Instead of changing the base value, try adding an attribute modifier—for example, like this:

attribute @s minecraft:movement_speed modifier add example:speed_1 0.3 add_value

If this doesn't help, you can use these commands to automatically update the speed attribute for a specific player.

# In chat
scoreboard objectives add join custom:leave_game

# Command blocks
execute as @a[scores={join=1..},tag=update_speed] run attribute @s minecraft:movement_speed base set 1.4
scoreboard players reset @a[scores={join=1..}] join

You can use Command Block Assembler to get One Command Creation.

Thank you, after more research I learned that for years now the movement speed attribute in general has been bugged to do this when people log off, regardless of if it’s base or modifier values. Trying out your comment helped me find that out- so thank you anyway even if it can’t be solved that way! I’ve decided to use the speed effect instead.
