[1.7.10] Client won't start (Crash log included)

Posted December 9, 20159 yr

So my friends and I made a modded pack on the Technic launcher. After updating a few mods, I found I could no longer launch the client. It would immediately go back to the launcher after trying to start.

Here's the crash log: http://pastebin.com/tKnaHFKY

Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file net/minecraft/client/gui/inventory/GuiContainer

One of your coremods is adding a duplicate method (probably

func_146977_a

drawSlot

) to the

GuiContainer

class using ASM. See if you can narrow down which mod (or combination of mods) is causing it and report it to the author(s). AE2 and ChickenBones' mods (CodeChickenLib, CodeChickenCore, NEI) seem to be the most likely causes based on the log.

Make sure you're using the latest available version of every mod before reporting the issue.

To narrow down the cause, you can perform a binary search:

[*]Disable half your mods

[*]If the problem persists, it's caused by an enabled mod; so disable half of the currently enabled mods

[*]If the problem goes away, it's caused by a disabled mod; so disable the currently enabled mods and enable the other half

[*]Repeat until you find the cause

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Thank you. It's Applied Energistics is causing the issue. I'll see what I can do about it.

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated

Bad pathfinding for big mobs (1.21.1)

I've struggled with this for way too long now, so I have decided to ask for some assistance here because there is almost no information about this online.

I made a hostile mob and I built it like this:
public static final Supplier<EntityType<Bunyip>> BUNYIP = ENTITY_TYPES.register("bunyip" , () -> EntityType.Builder. of(Bunyip::new, MobCategory.MONSTER).sized(3f, 2.5f).eyeHeight(1.75f).build("bunyip"));

However, I have discovered that a BoundingBox of 3 is too big for the vanilla pathfinding to work well. In fact, anything bigger than a block will not work well. This is especially noticeable when having it chase a player in a negative X and/or negative Z direction. The mob starts spinning, walking backwards, walking diagonally, etc.

I am using the Goal system:
protected void registerGoals() { super.registerGoals(); this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 1.25, true)); this.targetSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, true, true)); }

This does not seem to be a me issue as the ravager, one of the biggest vanilla mobs, also struggles with proper pathfinding. I am a bit familiar with how Minecraft's pathfinding works, but not enough to make a pathfinding system from scratch (or at least not in a reasonable amount of time). Is there any way to fix this with some tweaks or will I have to make a custom pathfinding system?
