SilentAssassin8

I have no errors in eclipse but when I run the game, I keep getting this error: cpw.mods.fml.common.LoaderException: java.lang.NullPointerException at cpw.mods.fml.common.registry.GameRegistry.registerBlock(GameRegistry.java:246) at cpw.mods.fml.common.registry.GameRegistry.registerBlock(GameRegistry.java:220) at cpw.mods.fml.common.registry.GameRegistry.registerBlock(GameRegistry.java:196) at Falconry.common.Falconry.Init(Falconry.java:51) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at cpw.mods.fml.common.FMLModContainer.handleModStateEvent(FMLModContainer.java:485) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.propogateStateMessage(LoadController.java:140) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.distributeStateMessage(LoadController.java:83) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:657) at cpw.mods.fml.client.FMLClientHandler.finishMinecraftLoading(FMLClientHandler.java:207) at net.minecraft.client.Minecraft.startGame(Minecraft.java:456) at net.minecraft.client.MinecraftAppletImpl.startGame(MinecraftAppletImpl.java:44) at net.minecraft.client.Minecraft.run(Minecraft.java:744) at java.lang.Thread.run(Thread.java:680) Caused by: java.lang.NullPointerException at cpw.mods.fml.common.registry.GameRegistry.registerBlock(GameRegistry.java:239) ... 34 more --- END ERROR REPORT 9e0706f4 ---------- Here is my main mod file: package Falconry.common;

Any help would be greatly appreciated.

I did see that one but it did not say 1.4.6 or current next to it so I was just wondering if it is still relevant.

I have an item and I want to use it to only open a gui. I will not store any items in it or use it for anything else. I'm not to familiar with Gui's so any advice on where to start with this one would be greatly appreciated.

I have the exact same problem. I tried replacing the jars like you said, but it still returned the same error when I reobfuscated.
