Minecraft Version

1.20.1

The Issue

Main errors in crash report and log.

The crash report points to three key issues that cause mods to fail to load:

1. Epic Fight (epicfight)

• Error: java.lang.NoSuchMethodError: 'net.minecraft.resources.ResourceLocation net.minecraft.resources.ResourceLocation.fromNamespaceAndPath(java.lang.String, java.lang.String)'
• Error location: yesman.epicfight.gameasset.EpicFightSounds.registerSound(EpicFightSounds.java:44)
• Description: The Epic Fight mod is attempting to use the ResourceLocation.fromNamespaceAndPath method, which is not present in the current version of Minecraft or Forge. This indicates that the mod version is incompatible with the version of Minecraft (1.20.1) or Forge (47.4.4) you are using. The fromNamespaceAndPath method was introduced in later versions of Minecraft (e.g. 1.20.2+), suggesting that the current version of the Epic Fight mod (11/20/10) may be for a newer version of the game or Forge.

2. Just Enough Items (jei)

• Error: java.lang.NoSuchMethodError: 'net.minecraft.resources.ResourceLocation net.minecraft.resources.ResourceLocation.fromNamespaceAndPath(java.lang.String, java.lang.String)'
• Error Location: yesman.epicfight.compat.JEIEpicFightPlugin.getPluginUid(JEIEpicFightPlugin.java:15)
• Description: There is an issue with Epic Fight integration with JEI. JEI mod (version 15.20.0.112) tries to load a plugin related to Epic Fight, but the loading fails due to the same problem with the ResourceLocation.fromNamespaceAndPath method. This confirms that the root of the problem is in Epic Fight.

3. Weapons of Miracles (wom)

• Error: java.lang.NoClassDefFoundError: yesman/epicfight/api/forgeevent/AnimationRegistryEvent
• Error location: reascer.wom.main.WeaponsOfMinecraft.<init>(WeaponsOfMinecraft.java:53)
• Description: Weapons of Miracles mod depends on Epic Fight and cannot load because the AnimationRegistryEvent class from Epic Fight is not available. This happens because Epic Fight itself failed to load due to the above error. Therefore, the crash of Weapons of Miracles is a consequence of the problem with Epic Fight.

The issue appeared when I installed these three mods:

• Epic Fight
• Simply Swords
• Weapons of Miracles - epic fight

Steps to Reproduce

Assemble the same mod-pack. I can offer to put my mod-pack on Google Drive and give you a link so that you don't have to search and download all the mods singly. You will only have to add Forge version 47.4.4.

My version Epic Fight is 20.11.10. I tried earlier versions, up to 20.11.5 - the result is the same.

[Yesssssman]

Forge has those newer version resource location getters in 1.20.1-47.4.4, they have backported them to ease the porting to 1.21.1.

You may have some corrupted forge version cached by Optifine but I have no clue since I can't access Optifine's code. So I just recommend using Oculus instead which is completely dependent on Forge API.

Beside that, Wom hasn't ported to latest Epic Fight. You have to check the dependent version of Epic Fight (latest wom uses 20.9.7)

Thank you. Indeed, this version worked. So far I just haven't figured out why some of the animations don't work. That is, none of the weapons have animations. Instead of new movements, the character just hits as before. However, the animation of the character itself has changed - stance, running, sneaking. We'll figure it out.
