Hey all,

 

I am trying to run some example code for item hud rendering, but when its finally called by the game, it always crashes:

 

java.lang.NoSuchMethodError: net.minecraft.client.Minecraft.getMinecraft()Lnet/minecraft/client/Minecraft;

 

What am I doing wrong? Thanks for any help!

 

 

technicly this is caused by the fact that the server calls thsi method, code please ?

 

 

use code tag too 

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:

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

 

 

 

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();
    }
}

well i doubt this will change anything, but try

 

Minecraft mc = FMLClientHandler.instance().getClient();

Thanks for the try, but unfortunately that instance of Minecraft is "empty" also:

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 :\

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()

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

Hm, nobody knows if he can run the wiki-example in 1.6.2?
