hey, I tryed to change "AttributeModifiers" on armor pieces and tools,
the equivalent to e.g.
"/give @p 301 1 0 {AttributeModifier:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:0.5,Operation:0,UUIDLeast:8000,UUIDMost:4000}]}".
(this would be seen on the item like "+x% speed").
but when the item is created, "on created" event, but i dont really know what im doing ..., and the posts ive found werent what i was looking for.
could someone hook me up with some info?
