Going to bump this one time (I could not find forum rules on bumping, but I dont intend to do it anymore here anyways). Some (new) things: - Still could not find a way to do it without reflection. Forge will probably have to step in there (Idk Im too afraid to ask or ping anyone). But I totally forgot about the reflection helper, so you should probably change the reflection fix to use the following (this already does the setAccessible(true) call, so just get the method using this): blockStatesInjector = ObfuscationReflectionHelper.findMethod(PointOfInterestType.class, "func_221052_a", PointOfInterestType.class); - There is a more modern way to register stuff which you probably wanna use. I have not known about it (like most others) so I will just put that here for the sake of progress:

In honor of this thread, Im going to quickly summarise what I have gathered about creating villagers professions in 1.14.4 (forge 28.1.109) as there is not really that much information about that available right now. If anyone sees me doing something wrong or saying bs, just let me know and I will fix it. Specifically the reflection fix I mention below. EDIT: Make sure you check the first couple replies as well. Source for all of this can be found specifically in this commit: https://github.com/CAS-ual-TY/GunCus/commit/817848784868f4e8362d4270be6f8fc19863dc42 Tho I have done a few extra things which are unrelated so dont wonder. PointOfInterestType If you check out the vanilla class, you could come to the conclusion, that these are generally types of points of interest for villagers. You have the blocks in there that give the villagers their professions (eg. the Armorer type has a Blast Furnace passed to the constructor), you have a Bed type for sleeping, Unemployed type, Meeting type, etc. (But most importantly you have all the professions). You make your POITypes in the forge registry event for that (Register<PointOfInterestType>) (dont forget to set the registry name). Constructor is: String name, Set<BlockState> blockStates, int maxFreeTickets, SoundEvent workSound, int something. Name seems to just be the lower case name (eg. "fletcher", "leatherworker" etc.), the blockStates are just all block states of the interest block. There is a helper method for this (unfortunately its private, so youll have to figure something out for yourself) which I will post below. Next you have what it seems to be the amount of villagers that can use this at once. All vanilla professions have this at 1. Next you have the work sound. I just use vanilla sounds here, so youll have to check yourself if your sound event public static final instances are populated already at this point. And finally you have another integer which I have no idea about. All vanilla professions have this at 1 too. VillagerProfession Now we create the villager profession. This is the type of profession a villager can have (eg. Flether, Weapon Smith etc.). We use the forge registry event for this again (Register<VillagerProfession>) (again, dont forget to set registry name). Constructor: String nameIn, PointOfInterestType pointOfInterestIn, ImmutableSet<Item> noIdea, ImmutableSet<Block> noIdeaAgain. The name is the lowercase name again (eg. "fisherman", "mason" etc.). This is needed for the texture and translation (see below). Next you pass the PointOfInterestType for this profession (read above that this is). Since P comes before V, these are already registered and object holders are populated, so you can just pass your static fields here. The 2 sets that come now I havent really looked into because all vanilla professions just pass an empty set here (ImmutableSet.of()). Profession Texture Location assets\MOD_ID\textures\entity\villager\profession\PROFESSION_NAME.png You just have to put the texture in the appropriate location. Rendering is done automatically. If you want to play around with the model a bit (eg. change the hat), check out the vanilla villagers. You can do that by adding extra PROFESSION_NAME.png.mcmeta files to the same location. Just check out vanilla for examples: assets\minecraft\textures\entity\villager\profession Profession Trading GUI Title Translation entity.minecraft.villager.MOD_ID.PROFESSION_NAME This is the key for your .lang file. Translate this to set the title of the trading GUI. At first I was confused, because there is 2 mod ids in there (mine and minecraft). But it makes sense because the villager is part of minecraft, but the professions part of *MOD_ID*. So ye. Adding Trades to Professions Forge has 2 events for that: VillagerTradesEvent, WandererTradesEvent. You can add trades to any profession here. 1st one allows to add trades to every profession and their levels (1-5, novice to master or smth). 2nd one allows to add generic or rare trades to the wanderer. I highly suggest checking out the vanilla trades to have an idea what (or how much) to set here for all the params: https://minecraft.gamepedia.com/Trading#Armorer - To do the first: Call event.getTrades().get(level).add(some_ITrade_instance_or_lamda_action). To do this for the profession you want, check if event.getType() == ModVillagerProfessions.YOUR_PROFESSION (this event gets called once for every profession). - To do the second: Just check out the event class. Pretty simple. Easy getters easy life I have made a helper class for this to allow easy trade creation. I will post it below. Example usage of this helper class (adds a trade to level 1; You can buy 2-4 (picked randomly per villager, but steady) acacia fences for 12 emeralds): event.getTrades().get(1).add(new RandomTradeBuilder(8, 10, 0.05F).setEmeraldPrice(12).setForSale(Items.ACACIA_FENCE, 2, 4).build()); Final Reflection Fix Im just going to quote what I have written on forge discord. See below for fix (in helper section, call for every POIType in your init): ------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------ Helper Stuff (use this as you please) Get all Block States static Set<BlockState> getAllStates(Block block) { return ImmutableSet.copyOf(block.getStateContainer().getValidStates()); } Easy/Random Trades Builder package here import java.util.Random; import java.util.function.Function; import net.minecraft.entity.merchant.villager.VillagerTrades.ITrade; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.Items; import net.minecraft.item.MerchantOffer; public class RandomTradeBuilder { protected Function<Random, ItemStack> price; protected Function<Random, ItemStack> price2; protected Function<Random, ItemStack> forSale; protected final int maxTrades; protected final int xp; protected final float priceMult; public RandomTradeBuilder(int maxTrades, int xp, float priceMult) { this.price = null; this.price2 = (random) -> ItemStack.EMPTY; this.forSale = null; this.maxTrades = maxTrades; this.xp = xp; this.priceMult = priceMult; } public RandomTradeBuilder setPrice(Function<Random, ItemStack> price) { this.price = price; return this; } public RandomTradeBuilder setPrice(Item item, int min, int max) { return this.setPrice(RandomTradeBuilder.createFunction(item, min, max)); } public RandomTradeBuilder setPrice2(Function<Random, ItemStack> price2) { this.price2 = price2; return this; } public RandomTradeBuilder setPrice2(Item item, int min, int max) { return this.setPrice2(RandomTradeBuilder.createFunction(item, min, max)); } public RandomTradeBuilder setForSale(Function<Random, ItemStack> forSale) { this.forSale = forSale; return this; } public RandomTradeBuilder setForSale(Item item, int min, int max) { return this.setForSale(RandomTradeBuilder.createFunction(item, min, max)); } public RandomTradeBuilder setEmeraldPrice(int emeralds) { return this.setPrice((random) -> new ItemStack(Items.EMERALD, emeralds)); } public RandomTradeBuilder setEmeraldPriceFor(int emeralds, Item item, int amt) { this.setEmeraldPrice(emeralds); return this.setForSale((random) -> new ItemStack(item, amt)); } public RandomTradeBuilder setEmeraldPriceFor(int emeralds, Item item) { return this.setEmeraldPriceFor(emeralds, item, 1); } public RandomTradeBuilder setEmeraldPrice(int min, int max) { return this.setPrice(Items.EMERALD, min, max); } public RandomTradeBuilder setEmeraldPriceFor(int min, int max, Item item, int amt) { this.setEmeraldPrice(min, max); return this.setForSale((random) -> new ItemStack(item, amt)); } public RandomTradeBuilder setEmeraldPriceFor(int min, int max, Item item) { return this.setEmeraldPriceFor(min, max, item, 1); } public boolean canBuild() { return this.price != null && this.forSale != null; } public ITrade build() { return (entity, random) -> !this.canBuild() ? null : new MerchantOffer(this.price.apply(random), this.price2.apply(random), this.forSale.apply(random), this.maxTrades, this.xp, this.priceMult); } public static Function<Random, ItemStack> createFunction(Item item, int min, int max) { return (random) -> new ItemStack(item, random.nextInt(max) + min); } } Reflection Fix private static Method blockStatesInjector; static { try { blockStatesInjector = PointOfInterestType.class.getDeclaredMethod("func_221052_a", PointOfInterestType.class); blockStatesInjector.setAccessible(true); } catch (NoSuchMethodException | SecurityException e) { e.printStackTrace(); } } public static void fixPOITypeBlockStates(PointOfInterestType poiType) { try { blockStatesInjector.invoke(null, poiType); } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException e) { e.printStackTrace(); } }

Just subscribe to the general Event class once and do all your handling and cancelling from there, eg. by having an array list of event classes you want to cancel. Something like ArrayList<Class> list ... void event(Event event) { for(Class c : list) if(c.equals(event.getClass())) event.setCanceled(true); }

Lets try a bump (please?)

Hello, Basically I have a folder which contains multiple sub-folders which are 1.14 mdks. The head folder is also the eclipse workspace and the sub-folders are eclipse projects each. In sub-folder 1 I am creating an API mod I intend to use for another mod, created in sub-folder 2. The API is open source, but it is on github (no maven). Now, what is the best way to now setup the mod workspace (folder 2) which needs the API (folder 1)? Can I just build a source jar of the api (folder 1) and then simply put it into a dependency folder for the mod (folder 2)? If yes, how? I tried lots of googling already, but I havent really found a solution where you have everything locally already. The topics I found pretty much all involved APIs from someone else, published online.

Not even that. The code you quoted does not even run the for bracket once.

Post your full Main.class and MOD.class so we can see the different lines. This is your error btw (shouldnt be hard to fix with java knowledge): Caused by: java.lang.NullPointerException at Gess.mod.Main.<init>(Main.java:38)

Yes blame the "lack of documentation". Totally not your java "knowledge". You also totally did not try to implement code that has such an obvious syntax error that someone with actual java knowledge would immediately see and be able to fix. Everything you need to do has been explained in this thread (and also the thread you linked where you stole the code from). Making this mod probably takes about 5 minutes.

The main mistakes here are lack of java knowledge. - In your topic you create a new instance of something, but nothing is being done with it, nothing gets called because of instantiation. - In your last example your syntax does not work at all (as pointed out already). These are things that have nothing to do with forge documentation. Surely there are things you have to know beforehand, but these are all listed here (itemstacks are point 12): Again, if you show me how you implemented my previous suggestion(s) I can help you with it.

Unless you show us how you did it there is no way we can help you.

The annotation basically tells forge "ey there is an event here". Then forge checks which parameter that method has and sends the corresponding event. Just as a simple explanation. So you subscribe to the tick event and in there you create a new instance of invChk every single tick. And in there you dont even call the method. The annotation doesnt work in invChk since there are no method params. Solution: add the client tick event parameter to the method in invChk instead (remove the entire thing in your mod class) and then pass an instance of said class to MinecraftForge.EVENT_BUS.register

Read the thread I linked. It tells you how to do it. Or options on how to do it.

These are your options listed in there. I have given my own implementation which in the current state you can find here: https://github.com/CAS-ual-TY/Visibilis/blob/c03f6972e3dc2845dbbdcc271ba1eee5b64a2bfc/src/main/java/de/cas_ual_ty/visibilis/util/RenderUtility.java#L410 (scissor methods, feel free to use these yourself) The only thing is that you have to account for mouse position. There is no hacky way around that, you have to do old fashion calculations.
