[1.8]A little bit confused with Rendering on 1.8


Cerandior

Recommended Posts

For about some time now i have started a 1.8 mod project. I have started it mostly like a test project to learn more about the way Forge 1.8 works but depending on the way it turns out this project may be published. So today i found some time and started working. I am getting a little bit confused over the rendering. I saw a simple tutorial and then tried to recreate the thing my own way. After i finished it seemed that i had done the most part of simple rendering for items and block using .json however everytime i start the game it just crashes on PreInit phase if i am not mistaken. Maybe i am derping and this is an obvious error, but this is the first time for me working on 1.8 so excuse the non-efficient coding(if there is any).

 

Here is the crash-report:

Do you get the exact same error? What may help would be to put a new line between each function call (so

    Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(Asolin.MODID + ":" + item.getUnlocalizedName().substring(5), "inventory"));

would become:

    Minecraft.getMinecraft()

    .getRenderItem()

    .getItemModelMesher()

    .register(item, 0, new ModelResourceLocation(Asolin.MODID + ":" + item.

    getUnlocalizedName().

    substring(5), "inventory"));

So you can see which function call is throwing an error, rather than just "somewhere in the entire line".

Your

Init

and

postInit

methods are both handling

FMLPreInitializationEvent

instead of handling

FMLInitializationEvent

and

FMLPostInitializationEvent

.

 

The

RenderItem

instance is created between preInit and init, so it's still

null

when you try to register your item models in the preInit phase.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

All things for rendering (e.g.meshing and renderers) are client-only. The server doesn't do display.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

Sorry, I saw the word "renderer" in the main class and commented. My own style is to call proxy.init (or preInit) and not have any mention of client-only features until inside my client proxy. In my own code, calls like ItemRenderer.registerItemRender() and proxy.registerRenderInfo() would be red flags.

 

Incidentally, your ItemRenderer class has "import net.minecraft.client.Minecraft". Isn't that a client-only class (hence "client" in its path)?

That is not incidentally imported.

Minecraft.getMinecraft uses it. And minecraft.getMinecraft it's client only

I'm glad you found the error.
