[1.11.2] Loop through Json file

Recommended Posts

I am adding an entity with a trading ability to my mod. The trades are defined using Json and I would like some help trying to figure out how to deserialize the file. I have looked through the Minecraft source to see how they do it and have googled, but I still do not understand how to do it. All help is appreciated.

 

Here is an example of how the Json is structured:

{
    "name": "Example Trade List",
    "professions": [
        {
            "name": "blacksmith",
            "careers": [
                {
                    "name": "toolsmith",
                    "offers": [
                        {
                            "output": {"id": "minecraft:golden_pickaxe", "meta": 0, "count": {"min": 1, "max": 4},
                                "tag":
                                {
                                    "ench": [{"id": 34, "level": 3}, {"id": 70, "level": 1}],
                                    "display": {"name": "Golden Pickaxe", "color": "FFFF55", "lore": ["A Golden Pickaxe", "Forged with magic"]}
                                }
                            },
                            "inputA": {"id": "minecraft:gold_ingot", "meta": 0, "count": {"min": 3, "max": 3}},
                            "inputB": {"id": "minecraft:stick", "meta": 0, "count": {"min": 2, "max": 2}},
                            "level": 0,
                            "stock": {"min": 2, "max": 4}
                        }
                    ]
                }
            ]
        }
    ]
}

You shouldn't be manually parsing JSON files. You should be using a deserializer.

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.

I think I have all of the groundwork set up. Here are the classes:

Am I doing it correctly? Also, now how do I fill out the Deserializer classes?

You don't need to write the deserializer manually. If you match your class structure with your JSON structure, Gson can do it for you. Check out the Gson User Guide.

Are the classes set up correctly? And, how would I best go about writing the TradeOffer class?

They look alright.

The TradeOffer class has to contain the fields that are present in the offer section of your JSON. You will have to write a custom deserializer for ItemStack.

 

And again, read the user guide. It answers all your questions.

I have it working now. Do you have any suggestions on how I can improve it?
