Posted August 8, 20169 yr Hi all, I am currently working on a mod that adds rpg-like skills to Minecraft using a Capability attached to EntityPlayer. Right now, the system works just fine on an Integrated Server, but upon attempting to launch it on a Dedicated Server, the line registering the capability encounters a NoClassDefFoundError: https://github.com/archery2000/Mod/blob/master/Crashlog Here is the part of my code that is probably related to the crash: https://github.com/archery2000/Mod/blob/master/skills/core/SkillCapability.java https://github.com/archery2000/Mod/blob/master/core/Main.java https://github.com/archery2000/Mod/blob/master/core/CommonProxy.java https://github.com/archery2000/Mod/blob/master/core/ServerProxy.java https://github.com/archery2000/Mod/blob/master/core/ClientProxy.java Would be so grateful if someone could point me in the right direction. Thanks! Edit: Thanks to Abastro, I figured out the source of the problem. By only injecting it in Common Proxy and referring to it from all my other files, the error is prevented.
August 8, 20169 yr replace if (FMLCommonHandler.instance().getEffectiveSide().isClient() w/ if (event.getSide() == Side.CLIENT)
August 9, 20169 yr By the way, why is this in the Common proxy? https://github.com/archery2000/Mod/blob/master/core/CommonProxy.java#L48 Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
August 9, 20169 yr Author replace if (FMLCommonHandler.instance().getEffectiveSide().isClient() w/ if (event.getSide() == Side.CLIENT) It didn't work, here's the second crashlog(which looks about the same): https://github.com/archery2000/Mod/blob/master/Crashlog2 May I know the rationale behind the change? Also, if it is important, I use several packets to update the skill information between client and server, where I update the capability information in the packet handler under the appropriate thread. By the way, why is this in the Common proxy? https://github.com/archery2000/Mod/blob/master/core/CommonProxy.java#L48 That's from an FX handler that was updated from 1.8. In it, all the FX used by my mod is managed. It was added into Common by accident and has been removed. Thanks!
August 9, 20169 yr Your crash is caused by using EntityPlayerSP somewhere in your code. VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect. Forge and vanilla BlockState generator.
August 9, 20169 yr Author Your crash is caused by using EntityPlayerSP somewhere in your code. Yes, that I know, but the issue is that I have no idea how to remedy it. There are only two places where EntityPlayerSP is used. The first is in my packet handlers which are intended to sync capability data from server to client(the player on client side is gotten using Minecraft.getMinecraft().thePlayer. I suppose it is not wrong to attach the capability to this instance of the player? Or is there another 'player entity' that I am supposed to attach it to? The second is in GUIs because I render the skill bar on the HUD. In this case, the player is again obtained using Minecraft.getMinecraft().thePlayer, because it is client sided only. Regardless, I don't really understand why the error comes up in initialisation.
August 9, 20169 yr Check all part where the casting capability is injected. Client-only code shouldn't be referenced on the same class with the injection. I. Stellarium for Minecraft: Configurable Universe for Minecraft! (WIP) II. Stellar Sky, Better Star Rendering&Sky Utility mod, had separated from Stellarium.
August 9, 20169 yr Author Thanks for the help! I had no idea that simply injecting would cause this issue. Why is it so even if the code is never run on the server side?
August 9, 20169 yr Because the class is loaded . Merely by being called into existence, the JVM needs to load up every class that it then references before ANY method can be run. Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.
