Forge doesn't work with magic launcher.

Posted April 27, 201312 yr

Today I downloaded the recommended forge build (universal) for minecraft 1.5.1. I tried to launch it with magic launcher without any other mods and a clean minecraft.jar (1.5.1). Minecraft didn't launch and I received this log:

*** MagicMinecraftLauncher 1.0.0 ***

java.lang.IncompatibleClassChangeError: Implementing class

at java.lang.ClassLoader.defineClass1(Native Method)

at magic.launcher.Launcher.main(Unknown Source)

It only happens with forge.

You've installed the wrong version of forge for the wrong version of minecraft, yes you say you're doing 1.5.1 vs 1.5.1 but your error log states otherwise.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

I'm 100% sure I have minecraft 1.5.1 because I force updated minecraft and in the main menu it says 1.5.1.

And for forge I have the "minecraftforge-universal-1.5.1-7.7.1.662.zip"

Then speak with the Magiclauncher people.. it would be an issue on there end. If you're absolutely sure its not your issue.

I'm fairly sure its your issue as many people use MagicLauncher with Forge just fine...

Either way it's not our issue. The install process is relay easy, just use our classes over the vanilla classes.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
