[SORTA SOLVED][1.6.4] getting int with metadata from ItemStack

[saxon564]

Heres the code i need help with:

 

this.tasks.addTask(3, new ChickAITempt(this, 1.0D, new ItemStack(Item.dyePowder, 1, 3).itemID, false));

 

i need to pass new ItemStack(Item.dyePowder, 1, 3).itemID on to ChickAITempt with the metadata of 3. but i cant get it to send without changing the constructor of ChickAITempt, which will break it with all the other mobs. could someone show me what i need to do to send the metadata to the ChickAITempt class?

You probably can't, as the constructor deals with only an item ID (which, why you'd create an item stack only to get the item's ID out of it, when you could just skip the item stack, I have no idea).  If you take a peek inside AITempt, you'll either find out that it doesn't care OR you'll find the variable that holds the information and how to set it.

[saxon564]

the constructor asks for an int, i can change that if i wanted, but i would have to change several other classes to match it, as for it not caring, thats because it simply is just that, unless there is a way, it doesnt care, and any dye will do what im trying to do, but i only want the cocoa beans to be used.

 

heres the code for EntityAIChick:

Create (add, not replace) your own AI class that acceps an ItemStack?

[saxon564]

this IS my own, i had to do it customize a few things in it. i could probably change it around a bit more, though if i dont want to do that if i dont have to. thats why i came here and asked.

[Draco18s]

You know you can have multiple constructors...right?

[saxon564]

tried multiple constructors and it still didnt work, so i decided just to make another AI class to deal with meta blocks which now works.
