I have created an EntityData that I want to save when the world closes and load that save when the world opens. private static final EntityDataAccessor<Float> ENGINE_POWER = SynchedEntityData.defineId(AircraftVehicle.class, EntityDataSerializers.FLOAT); @Override protected void defineSynchedData(SynchedEntityData.Builder builder) { super.defineSynchedData(builder); builder.define(ENGINE_POWER, 0f); } @Override protected void addAdditionalSaveData(CompoundTag compoundTag) { super.addAdditionalSaveData(compoundTag); compoundTag.putFloat("EnginePower", entityData.get(ENGINE_POWER)); } @Override protected void readAdditionalSaveData(CompoundTag compoundTag) { super.readAdditionalSaveData(compoundTag); if (compoundTag.contains("EnginePower")) { entityData.set(ENGINE_POWER, compoundTag.getFloat("EnginePower")); } } The problem is that entityData.get(ENGINE_POWER) in addAdditionalSaveData method always return the default value

Nevermind, just tested again and it again with an empty modpack and it worked

Add the crash-report

Just tried to make one that's just forge without any mods and it still crashes. There are also no mods installed in my entire instances folder called "jukeboxfix".

Remove canary or servercore

Make a test with Forge only - without any mods Or use a pre-configured modpack as working base and add new mods one by one

so my friend is unable to play this and atleast 1 other modpack that load just fine for me, this specific modpack is a version of Cisco's Fantasy Medieval RPG [Ultimate]-V5bRe.zip the end bit is the version of the mod it is, and its not the newest cause we tried switching versions if that would fix the error code 1 issue, then found a reddit post that said how to get the logs for it but the rest of the fix i didnt know how it worked or it just didnt work. help would be appreciated, and idk what all i need to provide but heres the logs atleast; https://docs.google.com/document/d/1VyncuA_EMMIk9vhq59I5O2oEVKGxdUD6jxpw4NMZQdI/edit?usp=sharing

I can't try right now but i doubt it would be one mod since i tried the classic "separate the mods folder into multiple folder and test each one individually", but every test i did crashed immediately :/

Playing in minecraft with mods

You can check attack range attribute or modify reach via custom predicates.

Same issue without the mod jukeboxfix?

Forge is probably the most feature loaded mod loader currently. You can change just about anything with the game mechanics by using mixins. You can also add more items and feature than what the docs show you. It is good to start with a Modding tutorial series like this one by Kaupenjoe. Some good examples of what is possible with forge is clockwork, dynamic trees, and I guess create but its on fabric too.

I'm new to modding and trying to make a mod in 1.20.1. My mod currently just has a custom bow, but when I use my bow, it does not play the animation. I have the jsons and pngs in the right spots and I've compared my jsons with that of existing mods, everything seems to line up just fine. Anyone know what might be causing this? I've changed the item between a basic BowItem and a custom class extending from BowItem, even overriding the animation code, no dice. odysseus_bow.json: { "parent": "item/generated", "textures": { "layer0": "odyssey:item/odysseus_bow" }, "overrides": [ { "predicate": { "pulling": 1 }, "model": "odyssey:item/odysseus_bow_pulling_0" }, { "predicate": { "pulling": 1, "pull": 0.65 }, "model": "odyssey:item/odysseus_bow_pulling_1" }, { "predicate": { "pulling": 1, "pull": 0.9 }, "model": "odyssey:item/odysseus_bow_pulling_2" } ] } odysseus_bow_pulling_0.json: { "parent": "item/generated", "textures": { "layer0": "odyssey:item/odysseus_bow_pulling_0" }, "display": { "thirdperson_righthand": { "rotation": [ -80, 260, -40 ], "translation": [ -1, -2, 2.5 ], "scale": [ 1.2, 0.9, 1.2 ] }, "firstperson_righthand": { "rotation": [ 0, -90, 25 ], "translation": [ 1.13, 3.2, 1.13 ], "scale": [ 0.88, 0.68, 0.88 ] } } } (_1 and _2 are the same with the respective layer0)

Hello I've been having some issues with Multipart entities and that it is constantly taking damage. The video below shows the issues. Also the hit boxes that are moving constantly seem to be still, because you can still be seated on the hit box where it is suppose to be. Here is some modified code taken from EnderDragonPart. public class TheHeartPart extends PartEntity<TheHeart> { public final TheHeart parentMob; public final String name; private final EntityDimensions size; public TheHeartPart(TheHeart pParentMob, String pName, float pWidth, float pHeight) { super(pParentMob); this.size = EntityDimensions.scalable(pWidth, pHeight); this.refreshDimensions(); this.parentMob = pParentMob; this.name = pName; } @Override protected void defineSynchedData() { } @Override protected void readAdditionalSaveData(CompoundTag pCompound) { } @Override protected void addAdditionalSaveData(CompoundTag pCompound) { } @Override public boolean isPickable() { return true; } @Nullable public ItemStack getPickResult() { return this.parentMob.getPickResult(); } @Override public boolean hurt(DamageSource pSource, float pAmount) { return false; //return this.isInvulnerableTo(pSource) ? false : this.parentMob.hurt(pSource, pAmount); } @Override public boolean is(Entity pEntity) { return this == pEntity || this.parentMob == pEntity; } @Override public Packet<ClientGamePacketListener> getAddEntityPacket() { throw new UnsupportedOperationException(); } @Override public EntityDimensions getDimensions(Pose pPose) { return this.size; } @Override public boolean shouldBeSaved() {return false;} } Any help is greatly appreciated!

I've been trying to run some modpacks through Prism launcher which haven't been working and I narrowed it down due to some forge issues. The issues only happen with modpacks using forge 1.20.1 so I tried to reinstall 1.20.1, but I keep getting this error log:https://pastebin.com/4w9pGURJ

'm having a problem with modded Minecraft when using CurseForge to install modpacks. Every time I launch the game with Forge, I get a black screen, but I can still hear the main menu music and button sounds when I click around. The game doesn't crash—it just stays black, making it unplayable. I've tried: Reinstalling the modpack Updating my graphics drivers Allocating more RAM Vanilla Minecraft runs fine, and even Forge loads without errors, but as soon as I start a modpack through CurseForge, I get this black screen issue. Has anyone else experienced this or know a fix?
