Hello everyone! I found a very simple solution to this problem that has bothered me too. In the class "ItemRender.java" in method "updateEquippedItem()" is an assignment to a variable named flag flag = this.equippedItemSlot == entityclientplayermp.inventory.currentItem && itemstack == this.itemToRender; To solve this problem, just replace that line with this boolean flag; if(itemstack == null) { flag = this.equippedItemSlot == entityclientplayermp.inventory.currentItem && itemstack == this.itemToRender; } else { flag = this.equippedItemSlot == entityclientplayermp.inventory.currentItem && itemstack.itemID == this.itemToRender.itemID; } It worked, I'm using version 1.5.2.

Hi all, I have created a mod with a 3D model that I created in Techne. Then I added this 3D model to my mod, with this code: MinecraftForgeClient.registerItemRenderer(Gun.itemID, new ItemRenderP90()); This code works when I launch the client, but when I launch the server, I get this error: cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraft/client/multiplayer/WorldClient at cpw.mods.fml.common.LoadController.transition(LoadController.java:147) at cpw.mods.fml.common.Loader.loadMods(Loader.java:515) at cpw.mods.fml.server.FMLServerHandler.beginServerLoading(FMLServerHandler.java:85) at cpw.mods.fml.common.FMLCommonHandler.onServerStart(FMLCommonHandler.java:347) at net.minecraft.server.dedicated.DedicatedServer.startServer(DedicatedServer.java:69) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:431) at net.minecraft.server.ThreadMinecraftServer.run(ThreadMinecraftServer.java:16) Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/multiplayer/WorldClient at net.minecraftforge.client.MinecraftForgeClient.getStencilBits(MinecraftForgeClient.java:64) at net.minecraftforge.client.MinecraftForgeClient.<clinit>(MinecraftForgeClient.java:68) at mods.Gunscraft.mod_Gunscraft.preinit(mod_Gunscraft.java:181) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at cpw.mods.fml.common.FMLModContainer.handleModStateEvent(FMLModContainer.java:494) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:74) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:314) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:296) at com.google.common.eventbus.EventBus.post(EventBus.java:267) at cpw.mods.fml.common.LoadController.sendEventToModContainer(LoadController.java:192) at cpw.mods.fml.common.LoadController.propogateStateMessage(LoadController.java:172) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:74) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:314) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:296) at com.google.common.eventbus.EventBus.post(EventBus.java:267) at cpw.mods.fml.common.LoadController.distributeStateMessage(LoadController.java:103) at cpw.mods.fml.common.Loader.loadMods(Loader.java:514) ... 5 more Caused by: java.lang.ClassNotFoundException: net.minecraft.client.multiplayer.WorldClient at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:238) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 35 more Caused by: java.lang.RuntimeException: Attempted to load class net/minecraft/client/multiplayer/WorldClient for invalid side SERVER at cpw.mods.fml.common.asm.transformers.SideTransformer.transform(SideTransformer.java:50) at cpw.mods.fml.relauncher.RelaunchClassLoader.runTransformers(RelaunchClassLoader.java:352) at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:225) ... 37 more If I delete "MinecraftForgeClient.registerItemRender" code, the server works.

Ok.

Hello, I want to create a mod with some automatic guns with ammo, I created a 3D model for the mod, but now I don't know how I can do the code for the ammo/gun. Thanks!

No, I have the source.

And in Minecraft?

How I add a new parameter (as username, password, version, assetIndex, assetsDir...) in the client?

I need it because I have a custom client with a server and if that login system doesn't exist, all the player can enter in the server with any account.

The real problem is: I have a custom launcher modified by me with a custom login database made by me. The launcher start a custom client that is made for enter in a server. The launcher is open source and if a player modify the source and toggle the password option can enter in any account. So I thinked: this launcher create a txt file with the password and when the player enters the server the client take the password and execute the "/login pass". I do this because so much people don't know how tu use "/register pass pass" and "/login pass" commands. There are other solutions? :\

If I use "Minecraft.getMinecraft().thePlayer.sendChatMessage()" in multiplayer, I get this crash: ---- Minecraft Crash Report ---- // Daisy, daisy...

I don't host the server. The server is in a remote host, and the host don't have a .minecraft folder. A minecraft server don't have a .minecraft folder.

I need to execute the command with the content of the txt file.

I need to take the contents of a txt file in .minecraft folder and use it in Java. The event must be client-side.

I'm new in Java and in Minecraft modding. This is good? "PlayerEvent pe = new PlayerEvent(player);"
