[1.19] Attack speed not adding up.

[Lucie]

I'm trying to create a mob effect similar to the Haste effect. I copied the code from the Haste effect and changed the UUID. Code below is a snippet from the effect.

.addAttributeModifier(Attributes.ATTACK_SPEED, UUID.randomUUID().toString(), 0.1F, AttributeModifier.Operation.MULTIPLY_TOTAL)

Testing the effect in Minecraft grants lesser attack speed than Haste even though it uses the exact same value (0.1). How do i fix it?

There is no Dig Speed Attribute, im not sure why vanilla adds an Attack Speed AttributeModifier to the Haste Effect.
If you want to have an Effect which work similar to the Haste Effect you need to modify the block break speed in PlayerEvent.BreakSpeed based on the amplifier of your Effect.

Looking at Player#getDigSpeed i see now how haste actually works, I'll do something similar in PlayerEvent#BreakSpeed. Thank you!
