Forge crashing in development mode.

Hi,

I just set up a forge workspace. Every time I try to run it, this happens:

How exactly did you set up forge? I'm guessing you didn't install it correctly.

I cd'd to the forge folder and typed python install.py. The workspace already had the assets, versions and mcl in it

Wait a minute. YOU'RE USING 6.4.45.953? For 1.6.4, 9.11.1.964 is the build you should be using! 6.4.45.953 is outdated as hell, I can make out cause for the latest 1.6.4 version 9 is the first number, while you have 6 as the first number.

I downloaded the latest forge source for 1.6.4 and set it up but it's still crashing! It's the same errors!

Any ideas?

The python system has been abandoned. Gradle is the new way forge works. Download version 964, not 965. Look up wuppy29's tutorials on how to set up gradle.

[SOLVED] Guys, please help me get through this horrible NoClassDefFound exception.

Well, needing help for this didn't last nearly as long as I expected, lol. I figured out the solution, and it's a real face palmer. Basically, the function Type.getInternalName(Class<?> clazz) does NOT work for classes that are obfuscated. This means that it won't work for basically every minecraft class. So running it with the argument EntityTrackerEntry.class won't work, but running it with CustomHandler.class will work! Annoying, but a still bit interesting. So I just replaced my call for Type.getInternalName(EntityTrackerEntry.class) with just "os", as that is the name of the actual class for EntityTrackerEntry at runtime. Hope this solution helps somebody. In the meantime, I'm going to mark this thread as solved.

Can you send the code pertaining to your custom mod effect? I don't see anything wrong with how you "assemble" the food properties, btw.

For anyone who is running into this issue in the future: The fix for me was updating Intellij. I was using the 2022 version, which apparently had some issues with Java 21 (particularly around enums, which Direction is one).

How do you add a mob to spawn around a existing vanilla structure?

Hey dawg!

I think I might be able to help you out with your issue here. I say might because I don't know about 1.16.x or any later version, but I know how to do this kind of thing for 1.12.2 forge. Basically, in the pre-init or init (I don't really remember which one) you just gotta'

Okay, ykw, I just downloaded the 1.14.4 1.20.1 minecraft mdk. I think I actually can help you here. So, the 1.12.2 method actually doesn't work with 1.20.1 minecraft or later. Probably not too far before either. I see two options here for ya':

First, it's important to note that the game stores its spawn data for structures in, well, the Structures class. Here, the game initializes an instance of each Structure class and registers them with the BootstrapContext using its bootstrap function. Each instance of a Structure class is registered with a StructureSettings class as an argument. One of the arguments, the one that you're probably going to be particularly interested in here, would be the spawnOverrides argument. For this argument, the game uses a Map between MOB_CATEGORIES and StructureSpawnOverride. StructureSpawnOverride is essentially the juice of it here. It contains almost everything you would need to control how your custom mob spawns in Pillager Outposts. Now, if you want to change how the Structure class for the pillager outposts is registered with the BootstrapContext in the bootstrap function, you're going to want to change where the function's caller gets the function and replace it with your own custom version of this function. How might you do this? This is where it gets a little tricky. The bootstrap function for the structures class is referenced in VanillaRegistries.BUILDER. However, unfortunately, this field is private and final, so you can't directly change it with reflections, but you can still access it with reflections. Now the VanillaRegistries.BUILDER field is of the type RegistrySetBuilder, which uses a private final field "entires", which is set as a List<RegistrySetBuilder.RegistryStub<?>> type. So here, you could use reflections to access this list field and remove the entry for the structures bootstrap. Then you might be able to create your own structures class and add change the bootstrap function to reflect the changes you wish. Then finally, simply re-add the Structure entry that you made to the list, and you should be completely done! Keep in mind, I haven't actually tested this, so I'm not sure if it would actually work, and even if it did work it's really unorthodox, so I would recommend trying this next idea.

When the game is deciding whether or not to spawn an entity, if the entity is registered with the SpawnPlacements class, is uses the function you specify in the entity class to determine whether or not the entity can spawn in a certain spot. For example, the guardian cannot spawn on a block that is exposed to light from underwater because of this function. So what you could do is make a checkSelfSpawnRules function for your mob and register it with the SpawnPlacements function. Then, you could have your checkSelfSpawnRules function take into account if the block it's trying to spawn on is near a Pillager Outpost. Finally, you can get the coordinates to the chunk of your block and iterate through the ServerLevels in your MinecraftServer class and get their chunk sources and test if the chunk source has the chunk of your block position. If it does, you can then get the StructureManager from the ServerLevel. In there should be some very helpful functions for you to use. Although this is a bit more orthodox, it might be a bit laggy.

It's really up to you which of these options you choose. If you need some additional clarification then please let me know, I would be happy to help you out! Also let me know if any of these options hit your goals for what your looking for here or not. If not then just let me know; I could probably find another method you could try.
