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.

 

 

 

 

public void onCreated(ItemStack stack, World world, EntityPlayer player) {

NBTTagCompound nbt = stack.getTagCompound();

}

 

 

 

could someone hook me up with some info?

A simple way to go would be something like:

if (!stack.hasTagCompound())
   stack.stackTagCompound = new NBTTagCompound();
if (!stack.stackTagCompound.hasKey("AttributeModifiers", Constants.NBT.TAG_LIST)
   stack.stackTagCompound.setTag("AttributeModifiers", new NBTTagList());

NBTTagList attributeModifiers = stack.stackTagCompound.getTagList("AttributeModifiers");
NBTTagCompound speedModifier = new NBTTagCompound();
speedModifier.setString("AttributeName", "generic.movementSpeed");
// ... Other things in the speed modifier NBT tag ...
attributeModifiers.appendTag(speedModifier);

There may be a better way, but this would work.

thanks! thats good enough
