[1.8] NullPointerException on Rendering


kandivia

Recommended Posts

Hello, I cannot seem to be able to render a simple item/block in forge 1.8-11.14.0.1299 using eclipse

I wrote a quick test mod to narrow down the problem.

 

The client crashes at the following method:

public static void registerRender(Item item){
	Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(Reference.MOD_ID + ":" + item.getUnlocalizedName().substring(5), "inventory"));	
}

with the corresponding crash details:

http://pastebin.com/0XSA7642

 

I have both a model file in "src\main\resources\assets\testmod\models\item"  called "test_item.json"

and a texture in "src\main\resources\assets\testmod\textures\items" called "test_item.png"

public static final String SERVER_PROXY_CLASS = "com.kandivia.testmod.proxy.CommonProxy";

}

 

Rendering is in the init method and should run well after Item registers in the preInit method

1. Renderers should be in load(). (you are good here).

2. Are you sure you know how .substring(index) works? You are taking String from 5 index to end. (That will cause bad texture naming).

 

I am sorry, I don't see anything. My code looks very similar. ;c

P.S: Be on the safe side - check for null in registerRender(Item item)

 

1.7.10 is no longer supported by forge, you are on your own.

item.getUnlocalizedName().substring(5) equates to "testitem" as doubled checked with a simple print statement

 

So it should be the same as:

new ModelResourceLocation("testmod:testitem", "inventory");

 

Running the game is just fine without running the render code. Trying to check for null atm.

This would not be directly related with your issue, but you should import and access Minecraft only in client proxy or client-only class.

I. Stellarium for Minecraft: Configurable Universe for Minecraft! (WIP)

II. Stellar Sky, Better Star Rendering&Sky Utility mod, had separated from Stellarium.

Narrowed the problem down futher today. Seems like i can't reference testitem after preInit?

 

Will Crash:

public static void registerRender(Item item){
String name = item.getUnlocalizedName().substring(5);
}

 

No Crash:

public static void registerRender(Item item){
String name = "testmod:testitem";
}

 

Will Crash:

public static void registerRender(Item item){
ModelResourceLocation loc = new ModelResourceLocation("testmod:testitem", "inventory");
Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, loc); // Crash on this line	
}

    • Hello. I've been having a problem when launching minecraft forge. It just doesn't open the game, and leaves me with this "(exit code 1)" error. Both regular and optifine versions of minecraft launch just fine, tried both with 1.18.2 and 1.20.1. I can assure that my drivers are updated so that can't be it, and i've tried using Java 17, 18 and 21 to no avail. Even with no mods installed, the thing won't launch. I'll leave the log here, although it's in spanish: https://jmp.sh/s/FPqGBSi30fzKJDt2M1gc My specs are this: Ryzen 3 4100 || Radeon R9 280x || 16gb ram || Windows 10 I'd appreciate any help, thank you in advance.
    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
