Is there a method to get all the loot that could spawn in a dungeon? An ArrayList is ok but I'd prefer an array.

Possibly something like this, using reflect. Where ChestGenHooks.EnumType is passed through

private ItemStack[] getDungeonLoot(ChestGenHooks cgh) {
	try {
		Field field = cgh.getClass().getDeclaredField("contents");

		if (!Modifier.isPublic(field.getModifiers()) || !Modifier.isPublic(field.getDeclaringClass().getModifiers())) {
			field.setAccessible(true);

			ArrayList<WeightedRandomChestContent> list = (ArrayList<WeightedRandomChestContent>) field.get(cgh);
			ArrayList<ItemStack> isl = new ArrayList<ItemStack>();

			for (WeightedRandomChestContent wrcc: list) {
				isl.add(wrcc.theItemId);
			}

			return isl.toArray(new ItemStack[isl.size()]);
		}
	} catch (NoSuchFieldException e) {
		e.printStackTrace();
	} catch (SecurityException e) {
		e.printStackTrace();
	} catch (IllegalArgumentException e) {
		e.printStackTrace();
	} catch (IllegalAccessException e) {
		e.printStackTrace();
	}

	return null;
}

 

NOTE: I've never used reflect in Minecraft and I'm not sure if it'll work. Also, I'm not the best at using it. Just putting it up as a suggestion.

I've used reflection in MC before; it works. Just don't remember what though... I think it was actually an Enum as well

Reflection will work with this since it's a class that is added by Forge. Therefore, when the classes are reobfuscated, these classes' members are not changed. However, attempting to use reflection on Minecraft source will cause problems outside of MCP. Just want to make this clear for future reference.

I feel proud

Why use reflection here 

You have public methods in ChestGenHooks class !

Look at getItems(args)...

getItems(Random) will not work since it only generates a random selection of loot. He wants a list of ALL loot that could spawn there.

getItems(Random) will not work since it only generates a random selection of loot. He wants a list of ALL loot that could spawn there.

And that's exactly what he would get with getItems(Random).

It isn't a random selection of loot. It is a complete array of randomized loots. Read the code, don't just assume by the name or argument.

 

By the way, one can also use WorldGenDungeons.field_111189_a (though this list is incomplete, as the enchanted book item is added later to the chests list).
