I am starting to experiment with modding for 1.9.4, and I figured out how to register items, but I'm having more trouble with blocks. The game crashes when the method, 'RegisterRenders' from my block init class is called by my client proxy class. I can't figure out what I'm doing wrong, so can someone please help me? Thanks in advance.

Tell me if you need any more details.

I tried changing my registerRender method to this, but I'm pretty sure I'm still doing something wrong

public static void registerRender (Block block, String resloc) {
Item item = ItemBlock.getItemFromBlock(block);

ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation(Reference.MOD_ID + ":" + resloc, "inventory"));
}

 

You mentioned registering an ItemBlock, and I noticed that both Item and ItemBlock had the method getItemFromBlock, so I tried using ItemBlock instead of Item. It clearly didn't work.

Okay, I managed to not make it crash by changing my registerRender method to this:

public static void registerRender (Block block, String name) {
ItemModelMesher mesher = Minecraft.getMinecraft().getRenderItem().getItemModelMesher();

mesher.register(Item.getItemFromBlock(block), 0, new ModelResourceLocation(Reference.MOD_ID + ":" + name, "inventory"));
}

However, when I run the game the block doesn't appear as if it wasn't registered.

I'm having trouble understanding exactly what I need to do... Please forgive me.

I got it working. My problem was that I wasn't setting the registry name for the block. Thanks for the help.
