Solved Editing Player Stats

I'm trying to edit basic player attributes, like attack_speed, hunger bar (total, don't know if this is possible), health bar total. I've gotten to the point of

Code:

            HumanEntity p = (HumanEntity) player;
            MetadataValue mdv = p.getMetadata("");

but I'm unsure what types of MetaDataValues are their. This also returns a list, not a singular value, I understand this but it really doesn't matter because I don't know how to get anything . If any knows or can direct me to a list of them that would be great, also if I'm doing this completely wrong please tell me (I'll research the right way and if I don't come to a conclusion I'll let you know)

Well, the method getMetadata has nothing to do with the attributes you're talking about. Metadata is a way for plugins to store information on players. To modify an attribute, simply do this:

Code:java

player.getAttribute(Attribute.GENERIC_ATTACK_SPEED).setBaseValue(1024)

Here's a list of all possible attributes:

Thanks, I already found the answer from some friends anyways (Was just going to mark this as solved) XD
