How to make a Core mods

Posted May 17, 201312 yr

I was wondering, how would I go about making a core mod? From what I understand, core mods allow you to "edit" base classes without actually editing them. And if that is true, then I definitely need it for my mod.

And I believe this is done with ASM transformers? How would I use those?

I have also found that I really love making extremely long and extremely but sometimes not so descriptive variables. Sort of like what I just did there

I've never made one, but it looks like you just sort of... compile your replacement code and paste it into the .class file, or perhaps the memory image of the class file? Like with any bytecode, if you literally just write in instructions after an instruction in the bytecode, then those instructions you added will happen ater the one you inserted after, and before the one after that. (conditionals nonwithstanding)

Hmm... maybe....

What I really want to know is what a core mod does, and what are good uses for them

Hmm... I'm thinking that if I want to give the vanilla items custom abilities then I should use this...

So, what are good uses for core mods?

Well, my future coremod will inject a new method in the Item class, which gets called by injected code in the EntityPlayerSP class. Also it creates some public getters and setters for stuff. But it's more worth it if you actually want to inject or edit a code snippet / a (new) method / interface / etc.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

FTBQuests quests not showing in server

Most likely, this is no longer relevant for you, but I will still leave my answer, because I had the same problem, and I did not find a clear answer anywhere. To ensure your server players have the quests you created, all you need to do is transfer the necessary files to the server. Players don't need to install anything on their end, except for mod. You need to find .minecraft>config>ftbquests>quests. In quests should be folder and two files. So all you need to do is use existing ones or create folders config>ftbquests>quests, and copy the contents of the quests folder.

Medium-sized modpack crashing when loading new chunks occasionally. (crash report)

Maybe an issue with majruszlibrary or a mod requiring it

[1.20.1] Custom Effect Help

Currently stuck on making a custom effect for forge 1.20.1
Im trying to add a certain number of hearts to a player once they consume a potion/custom item, i tried doing it with the vanilla effects and it didn't work the way i wanted it to work, so now im trying to make a custom effect that adds this configurable amount of hearts

So far Ive been following KaupanJoes tutorial for both 1.21 and 1.20 and the effect doesn't seem to give any errors nor does its registration, however i cant seem to get it to work with applying it to the item itself

```package com.curseofaros.item; import com.curseofaros.effect.ModEffects; import net.minecraft.world.effect.MobEffectInstance; import net.minecraft.world.effect.MobEffects; import net.minecraft.world.food.FoodProperties; public class ModFoods { public static final FoodProperties FLASK_OF_LIFE = new FoodProperties.Builder()
.fast() .alwaysEat() .nutrition(0) .saturationMod(0)
.effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 2), 1.0f) .build();

public static final FoodProperties MEDIUM_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(ModEffects.MEDIUM_POTION_EFFECT.get())) .build();

public static final FoodProperties SMALL_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 3), 1.0f) .build(); }

(Sorry for the real shi formatting, don't really know how to do it smh, note im also fairly new to Java so i don't know a lot, please be patient and let me know if the error is simply a lack of understand of Java principles)

Add the crash-report without the mod better_randomsource_concurrency_crash
