Hello, i need to increase player speed by 2. I tried using entity attributes but it's didn't anything.

Code, which i tried to use:

player.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.5D);

You can't JUST do that.

 

Base Attribute is a generic value for entity. When you assign it to entity all entities (in this case players) will have this attribute.

If you want to edit whole base for all player instances you can do that, some method with "register" word or something, i don't remeber (idk if it will work because they are being registered in constructor).

 

What you need to use is AttributeModifier, there are 3 operation there, you can make entity go faster, similar to potion effect (that's what potions use).

And this will work per-player.

Also note, that I think the base value is only used once, during entity construction.
