Eling

I have a problem about register custom item model from block.Everything is good in the eclipse, but when I run it, it always crashes. A part of the crash report: BlockLoader.java : package xxx.xxx.common.block; import net.minecraft.block.Block; import net.minecraft.client.renderer.block.model.ModelResourceLocation; import net.minecraft.item.Item; import net.minecraft.item.ItemBlock; import net.minecraftforge.client.model.ModelLoader; import net.minecraftforge.fml.common.registry.ForgeRegistries; import net.minecraftforge.fml.relauncher.Side; import net.minecraftforge.fml.relauncher.SideOnly; public class BlockLoader { public static Block blockXxxx = new BlockXxxx().setUnlocalizedName("xxxx"); public void init() { ForgeRegistries.BLOCKS.register(blockXxxx.setRegistryName("xxxx")); ForgeRegistries.ITEMS.register(new ItemBlock(blockXxxx).setRegistryName(blockXxxx.getRegistryName())); //←The Line 28 } @SideOnly(Side.CLIENT) public static void clientInit() { ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(blockXxxx), 0, new ModelResourceLocation(blockXxxx.getRegistryName(), "inventory")); } } Thanks.
