I've solved the problem! Thanks a lot for your help, diesieben07 and DavidM.

If you don't mind, will you tell me what to do? I can't understand what you are saying, sorry...

I modified my code, but it doesn't work... private void doClientStuff(final FMLClientSetupEvent event) { RenderingRegistry.registerEntityRenderingHandler(EntityProactiv.class, new IRenderFactory<EntityProactiv>() { ItemRenderer itemRenderer = Minecraft.getInstance().getItemRenderer(); @Override public Render<? super EntityProactiv> createRenderFor(RenderManager manager) { return new RenderSprite<EntityProactiv>(manager, ModItems.proactiv, itemRenderer); } }); } ---- Minecraft Crash Report ---- // Who set us up the TNT?

I'd like to create an entity like snowball, and tried to use RenderSprite class as a renderer of my entity. private void doClientStuff(final FMLClientSetupEvent event) { ItemRenderer itemRenderer = Minecraft.getInstance().getItemRenderer(); RenderingRegistry.registerEntityRenderingHandler(EntityProactiv.class, new IRenderFactory<EntityProactiv>() { @Override public Render<? super EntityProactiv> createRenderFor(RenderManager manager) { return new RenderSprite<EntityProactiv>(manager, ModItems.proactiv, itemRenderer); } }); } (EntityProactive is the entity I'm creating.) However, when I throw the entity in the game, the game crashes on account of NullPointerException. Here is a part of a crash report. ---- Minecraft Crash Report ---- // But it works on my machine.
