hydroflame Posted July 19, 2013 Share Posted July 19, 2013 technicly this is caused by the fact that the server calls thsi method, code please ? use code tag too Quote how to debug 101:http://www.minecraftforge.net/wiki/Debug_101 -hydroflame, author of the forge revolution- Link to comment Share on other sites More sharing options...
kung foo man Posted July 19, 2013 Author Share Posted July 19, 2013 Hey, I'm just using this example: http://www.minecraftforge.net/wiki/Custom_2D_Inventory_Item_Renderer Also it's not running on server, since I'm connecting to my server by IP and it is still crashing. Maybe it's helpful, a full error stack trace with the function commented out. Then Java can't find other methods or instances: ---- Minecraft Crash Report ---- // Hey, that tickles! Hehehe!

hydroflame Posted July 19, 2013 Share Posted July 19, 2013 ok 1 use code tag 2 try running this code inside renderItem if(FMLCommonHandler.instance().getEffectiveSide().isServer()){ try{ throw new Exception("learning to coding is important"); }catch(Exception e){ e.printStackTrace(); } } this would output a ton of lines, paste them in a spoiler please Quote how to debug 101:http://www.minecraftforge.net/wiki/Debug_101 -hydroflame, author of the forge revolution- Link to comment Share on other sites More sharing options...
kung foo man Posted July 19, 2013 Author Share Posted July 19, 2013 The code is not running on server. System.out.println("running on server: " + FMLCommonHandler.instance().getEffectiveSide().isServer()); if(FMLCommonHandler.instance().getEffectiveSide().isServer()){ try{ throw new Exception("learning to coding is important"); }catch(Exception e){ e.printStackTrace(); } } Client> 2013-07-19 21:35:43 [iNFO] [sTDOUT] running on server: false Quote Link to comment Share on other sites More sharing options...
hydroflame Posted July 19, 2013 Share Posted July 19, 2013 well i doubt this will change anything, but try Minecraft mc = FMLClientHandler.instance().getClient(); Quote how to debug 101:http://www.minecraftforge.net/wiki/Debug_101 -hydroflame, author of the forge revolution- Link to comment Share on other sites More sharing options...
kung foo man Posted July 19, 2013 Author Share Posted July 19, 2013 Thanks for the try, but unfortunately that instance of Minecraft is "empty" also: java.lang.NoSuchFieldError: fontRenderer at tutorial.generic.DamagedItemRenderer.renderItem(DamagedItemRenderer.java:61) at net.minecraftforge.client.ForgeHooksClient.renderInventoryItem(ForgeHooksClient.java:171) at net.minecraft.client.renderer.entity.RenderItem.func_82406_b(RenderItem.java:465) at net.minecraft.client.gui.inventory.GuiContainer.func_74192_a(GuiContainer.java:421) at net.minecraft.client.gui.inventory.GuiContainer.func_73863_a(GuiContainer.java:132) at net.minecraft.client.renderer.InventoryEffectRenderer.func_73863_a(SourceFile:31) at net.minecraft.client.gui.inventory.GuiInventory.func_73863_a(SourceFile:49) at net.minecraft.client.renderer.EntityRenderer.func_78480_b(EntityRenderer.java:1036) at net.minecraft.client.Minecraft.func_71411_J(Minecraft.java:934) at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:826) at net.minecraft.client.main.Main.main(SourceFile:101) 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 net.minecraft.launchwrapper.Launch.launch(Launch.java:57) at net.minecraft.launchwrapper.Launch.main(Launch.java:18) Quote Link to comment Share on other sites More sharing options...
hydroflame Posted July 19, 2013 Share Posted July 19, 2013 no an "empty" minecraft would have a null pointer exception on fontRenderer whiel you get a noSuchFieldException, tottally different are you using minecraft 1.6.x ? if yes they might have changed the location or name of Minecraft.fontRenderer wait that would mean it would fail at compilation time ... not at runtime .... if thats not it im afraid i have no idea :\ Quote how to debug 101:http://www.minecraftforge.net/wiki/Debug_101 -hydroflame, author of the forge revolution- Link to comment Share on other sites More sharing options...
kung foo man Posted July 19, 2013 Author Share Posted July 19, 2013 Yea, it's 1.6.2. The strange thing is, that I can't access anything at all besides the GL11-methods. Not working: Tessellator tessellator = Tessellator.instance; itemStack.getItemDamage() Minecraft.getMinecraft().fontRenderer itemStack.getIconIndex() Quote Link to comment Share on other sites More sharing options...
hydroflame Posted July 19, 2013 Share Posted July 19, 2013 hmmm, if you're using eclipse, try cleaning your project (Project -> clean... ) if that still doesnt work, try re installing mcp/forge again and restarting if THAT doesnt work its probably forge bug so use 1.6.1 or even 1.5.2 while this is being fixed, also, if you get to this step, report the bug to the bug board Quote how to debug 101:http://www.minecraftforge.net/wiki/Debug_101 -hydroflame, author of the forge revolution- Link to comment Share on other sites More sharing options...
kung foo man Posted July 19, 2013 Author Share Posted July 19, 2013 Hm, nobody knows if he can run the wiki-example in 1.6.2? Quote Link to comment Share on other sites More sharing options...
