[SOLVED][1.7.10] Adding items to generated chests

[Flenix]

Hey guys!

 

I've got a slightly weird issue, so bear with me. I'll explain it as best I can.

 

Basically, from what I understand the "normal" method of adding items to worldgen chests is using ChestGenHooks and WeightedRandomChestContent. From my understanding, that adds the item you provide to a list, which is then checked against when a chest is generated into the world, and it decides whether or not to generate your particular item based on the rarity value you provide.

 

Now, in my mod, I'm wanting to add roughly ~150 items to these generated chests. There should be about a 1 in 20 chance that a chest will contain a single one of these items - but I only want it to contain one in that situation. On top of that, some of my items should be "Rarer" than others.

 

Ideally, I want the game to simply call a method saying "I'm generating a chest now, what item should I add?", and then I can run my own code to decide which lucky item gets spawned in this situation (using RNGs to select the item type and then the rarity, and picking an item at random from the relevant category). This is how I handle stuff for mob drops and it works great.

 

Is there any way for me to do that with dungeon chests by default? It's not 100% the end of the world if not as I'm adding my own custom chests alongside them - but it would just be nice to support the vanilla systems too

 

(The other reason behind this is that about 50 of the items require a number of NBT values attached to function properly - meaning I'd have to create all those values for each itemstack when registering it. I dread to think how long and messy the class would get if I were to do that...)

 

Any help appreciated

I recommend walking through the vanilla code that adds chests. See if there's a suitable Forge event called at the end that gives you "last licks" to modify the chest contents. If "lucky", find an empty inventory slot and add your one dynamically generated special item.

I had a quick look through the events list and there's nothing specifically about creating chests, and the generation events don't seem to have any reference to them either - but the InitMapGenEvent does contain vague information about what structures are being generated.

 

I'll have a proper look through the code tonight and see if that's do-able. Hopefully there will be some way to grab it via an event, that's a good idea - but if not does anyone else have any other ideas?

Look at WeightedRandomChestContent, you can extend it and override WeightedRandomChestContent#generateChestContent() to have more control over loot.

That's exactly what I needed, thanks!
