Hi, this is a bit old now but depending on your version you could use Kaupenjoe's tutorials. He shows custom bows in versions 1.21 and 1.18. Here is the link to his channel.

I develop a mod called "Every Ore and More" but when I ran DataGen, it didn't work. Same thing with runClient. I am using Forge 1.20.1-47.3.11 in IntelliJ IDEA. The source code is available here: Github. It uses the following API: ErrorLib Here are the error logs: Error.txt on GitHub Does anyone know how I can fix this?

I tried implementation name, but gradle is telling be I should be using implementation fg.deobf(), but how would I do that? Edit: I fixed it.

I am trying to use a Mod I developed as an API, but I have no idea how. I do not intend to have it download from the internet or anything like other really popular APIs, just use a Jar file. The only tutorials I have been able to find have been really old, from 2014 or earlier. Does anyone know how to do this?

While you do not need this plugin, you can use it. I personally use it for Minecraft Plugin Development, but honestly I don't use it at all for Modding.

I have been practicing modding minecraft, and I needed to make a pine forest biome, but my game crashes whenever I try to either load into, or generate, a world. I have no idea why. I will upload my crash report and pine_forest.json files. I do have some java knowledge, but I am still fairly out of my depth here. Here is the tutorial I used: Forge Modding Tutorial - Minecraft 1.20.1: CUSTOM BIOMES | #43

@Tsuk1 You could use this tutorial that uses GeckoLib 4: https://www.youtube.com/watch?v=3zqxU7vjHmQ It is designed for 1.19.4 but it works for 1.20.1, I have tested. All you would need to do is only make it for a helmet. I'm not sure how you would do the general item model.

One of the mods I had installed was not working, so I just deleted it. The modpack I am making did not need it, we were just throwing together crazy and cool mods

I have fixed it now.

Hello, I am trying to make a forge 1.20.1 modpack, but when I load it, I get the following Minecraft Error: at cpw.mods.securejarhandler/cpw.mods.cl.ModuleClassLoader.loadFromModule(ModuleClassLoader.java:229) at cpw.mods.securejarhandler/cpw.mods.cl.ModuleClassLoader.findClass(ModuleClassLoader.java:219) at cpw.mods.securejarhandler/cpw.mods.cl.ModuleClassLoader.loadClass(ModuleClassLoader.java:135) at java.base/java.lang.ClassLoader.loadClass(Unknown Source) at java.base/java.lang.Class.getDeclaredFields0(Native Method) at java.base/java.lang.Class.privateGetDeclaredFields(Unknown Source) at java.base/java.lang.Class.getDeclaredFields(Unknown Source) at TRANSFORMER/net.optifine/net.optifine.reflect.FieldLocatorTypes.<init>(FieldLocatorTypes.java:25) at TRANSFORMER/net.optifine/net.optifine.reflect.Reflector.<clinit>(Reflector.java:541) at TRANSFORMER/[email protected]/net.minecraft.CrashReport.m_127526_(CrashReport.java:175) at TRANSFORMER/[email protected]/net.minecraft.CrashReport.m_127529_(CrashReport.java:345) at TRANSFORMER/[email protected]/net.minecraft.client.main.Main.main(Main.java:149) ... 15 more Caused by: org.spongepowered.asm.mixin.throwables.MixinApplyError: Mixin [lostfeatures.mixins.json:ClientLevelMixin] from phase [DEFAULT] in config [lostfeatures.mixins.json] FAILED during APPLY at MC-BOOTSTRAP/org.spongepowered.mixin/org.spongepowered.asm.mixin.transformer.MixinProcessor.handleMixinError(MixinProcessor.java:636) at MC-BOOTSTRAP/org.spongepowered.mixin/org.spongepowered.asm.mixin.transformer.MixinProcessor.handleMixinApplyError(MixinProcessor.java:588) at MC-BOOTSTRAP/org.spongepowered.mixin/org.spongepowered.asm.mixin.transformer.MixinProcessor.applyMixins(MixinProcessor.java:379) ... 36 more Caused by: org.spongepowered.asm.mixin.injection.throwables.InvalidInjectionException: Critical injection failure: @ModifyExpressionValue annotation on modifyCanSpawn could not find any targets matching 'm_263888_' in net.minecraft.client.multiplayer.ClientLevel.
