[1.6.4] Storing and Later Using Mob NBT Data in an Item

I'm a noob at working with NBT data.

 

The Premise: Players can create a Mob Net. It can store up to one mob at a time, then can be used to respawn the mob, with the NBT data it had before it was "picked up".

 

The Problem: I have practically no idea how to effectively use NBT data. I only know the extreme basics. Could someone help me?

if (user.hasKnowledgeOfJava) {

    if (user.question.hasCode) {

        return interpetHelpfulResponse(user.getQuestion());

    } else {

        return "Could you post your code please?";

    }

} else {

    return "Learn some freaking Java!";

}

    NBTdata is just key->value data storage that is automatically saved to disc when the game is shut down (or the chunk is unloaded, etc.)

     

    NBTdata can hold any simple data type (int, double, float, string, etc.) including arrays (int array, etc.), as well as NBT tags and NBT tag lists (an array of NBT tags)

     

    I believe the key name is required to be a string, but other than that, you're free to go hogwild.

     

    For example, I have one mod that stores item functionality in NBT data, so that the mod can hold millions (probably several hundred million at this point) of items in a single item ID (actually, 21, due to armor slot/material combinations required to be paired at construction).

     

    Then I have another mod that stores image data as arrays of integers.

    Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

     

    Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

     

    DO NOT PM ME WITH PROBLEMS. No help will be given.

    Thanks for the examples.

    if (user.hasKnowledgeOfJava) {

        if (user.question.hasCode) {

            return interpetHelpfulResponse(user.getQuestion());

        } else {

            return "Could you post your code please?";

        }

    } else {

        return "Learn some freaking Java!";

    }
