[1.10]NullpointerException when rendering custom Entity model

Recommended Posts

So I've made a custom entity extending Entitythrowable which works just fine. I've added a custom model to it. 

 

Code in my ClientProxy: 

 

    @Override
    public void preInit(FMLPreInitializationEvent e) {
		ItemRenderRegister.registerItemRenderer();
        RenderingRegistry.registerEntityRenderingHandler(EntityThrow.class, ThrowTinyFactory.INSTANCE);
        super.preInit(e);
    }

 

Code in my ThrowTinyFactory:

public class ThrowTinyFactory implements IRenderFactory<EntityThrow>{

    public static final ThrowTinyFactory INSTANCE = new ThrowTinyFactory();

    @Override
    public Render<? super EntityThrow> createRenderFor(RenderManager manager) {
        return new EntityRenderThrowTiny();
    }
}

 

Code in EntityRenderThrowTiny

public class EntityRenderThrowTiny extends Render {

    private ModelBase customModel;

    public EntityRenderThrowTiny(){
        super(Minecraft.getMinecraft().getRenderManager());
        customModel = new ThrowItemModel();
    }

    private final ResourceLocation EntityThrowTiny = new ResourceLocation( Main.MODID + ":" + "textures/modeltex/throwitem.png");

    @Override
    protected ResourceLocation getEntityTexture(Entity entity) {
        return getThrowTexture((EntityThrow)entity);
    }

    private ResourceLocation getThrowTexture(EntityThrow entity) {
        return EntityThrowTiny;
    }

    @Override
    public void doRender(Entity entity, double x, double y, double z, float entityYaw, float partialTicks){
        bindTexture(getEntityTexture(entity));
        GL11.glPushMatrix();
        GL11.glTranslated(x, y, z);
        customModel.render(entity, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0675F);
        GL11.glPopMatrix();

    }
}

 

 

The reason I've put super(Minecraft.getMinecraft.getRenderManager) in my Render is because I've made that class before I realized that I'd need a IRenderFactory. I realize this might be a mistake, but I'll elaborate on that later.

 

For now the error this gives me is:

The game just stops rendering and crashes the second I spawn the entity. which means there's some kind of nullpointerexception going on.  Now the relative path of my texture is: 

assets/rpvp/textures/modeltex/throwitem.png

which means that my ResourceLocation should be fully working, even if it crashes on the BindTexture.

 

Something is obviously wrong.

 

 

Now when I remove the Minecraft.getMinecraft.getRenderManager and instead allow the IRenderFactory to pass on the manager like so: 

 @Override
    public Render<? super Entity> createRenderFor(RenderManager manager) {
        return new EntityRenderThrowTiny(manager);
    public EntityRenderThrowTiny(RenderManager manager){
        super(manager);
        customModel = new ThrowItemModel();
    }

 

the code actually does work properly, as in the model is actually loaded. When I add a Println to my Model file it will actually show, meaning that the model is somehow getting loaded by passing on the RenderManager provided by the interface.

 

However, when I do that my texture doesn't show up at all. I've already tried to switch around my resourcelocation just to make sure, but no matter how I've tried to access it it just didn't want to work properly.

        modelRenderer.rotateAngleX = x;
        modelRenderer.rotateAngleY = y;
        modelRenderer.rotateAngleZ = z;
    }
}

 

 

 

Summary:

When using the RenderManager that IRenderFactory provides the model will load but it'll be invisible. When I try to pass on Minecraft.getMinecraft.getRenderManager() to my custom render class it just gives me a nullpointerexception.

I bind my texture in the doRender in my EntityRenderThrowTiny class as such.

    @Override
    public void doRender(Entity entity, double x, double y, double z, float entityYaw, float partialTicks){
        bindTexture(getEntityTexture(entity));
        GL11.glPushMatrix();
        GL11.glTranslated(x, y, z);
        customModel.render(entity, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0675F);
        GL11.glPopMatrix();

    }

 

unless bindTexture is not what I'm supposed to be using? Should I somehow bind my texture in the Renderfactory? I guess I could open up the Render class and have a look how that'd work.

Edit: For some reason the alpha channels on all of my boxes were set to 0.0F. I was trying to use Qubble which for some reason sets it like this by default. I guess I'll switch to a different helper for making models. Unless someone has some recommendations for what to use. I guess I could also try to manually change models, but that'd take a lot longer.

 

Marking as solved.
