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.

Will you tell me the problem of my code?

Obtain the ItemRenderer instance when your IRenderFactory is called.

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);
    }
  });
}

You need to do it when you are asked for the renderer.

If you don't mind, will you tell me what to do?

 

I can't understand what you are saying, sorry...

Get the instance of 

Minecraft.getInstance().getItemRenderer();

inside IRenderFactory#createRenderFor, and use the returned item renderer in 

new RenderSprite<EntityProactiv>

as the item renderer parameter.

Some tips:

Spoiler

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

4. 

Quote

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

6.

Quote

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

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