Dear Fellow Minecraft Modders,

i am currently trying to register an Screen Object in the FmlClientSetup event.

To do this many tutorial use the DefferdWorkQueue.runLater Method, but in my current minecraft forge version [1.15.2- 31.1.0] this class is deprecated and doesn't work.

So my question is what do is use instead to achieve the same goal.

The documentation recomends to use the IThreadListener but i cant find out how to use it over even where the Interface or class should be located.

 

When i launch the mod using the DefferdWorkQueue following error Message appears:

encounterd an errror processing defferd work

java.lang.NullPointerException: Registry Object not present

 

Source:

@SubscribeEvent
   public static void clientSetupEvent (final FMLClientSetupEvent event){
       
       DeferredWorkQueue.runLater(()->ScreenManager.registerFactory(ModContainerTypes.SOLAR_PANEL.get(),SolarPanelScreen::new));


   }

 

if you need more information in a happy to provide more.

Thank you for your quick reply. 

i included my log files because i don't understand what my mistake is.

 

my code is as follows:

 

public class ModContainerTypes {
    public static final DeferredRegister<ContainerType<?>> CONTAINER_TYPES = new DeferredRegister<>(ForgeRegistries.CONTAINERS, NovusTechnica.MODID);

    public static final RegistryObject<ContainerType<SolarPanelContainer>> SOLAR_PANEL = CONTAINER_TYPES.register("solar_panel",() -> (IForgeContainerType.create(SolarPanelContainer::new)));
}

 

 

public class SolarPanelScreen extends ContainerScreen<SolarPanelContainer> {

    private static final ResourceLocation BACKGROUND_TEXTURE = new ResourceLocation(NovusTechnica.MODID,"/textures/gui/solar_panle_container.png");

    public SolarPanelScreen(SolarPanelContainer screenContainer, PlayerInventory inv, ITextComponent titleIn) {
        super(screenContainer, inv, titleIn);
    }

    @Override
    protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) {
        RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F);
        getMinecraft().getTextureManager().bindTexture(BACKGROUND_TEXTURE);
        int startX = this.guiLeft;
        int startY = this.guiTop;

        this.blit(startX,startY, 0,0,this.xSize,this.ySize);

        final SolarPanelTileEntity tileEntity = container.tileEntity;
      final SettableEnergyStorage settableStorage = tileEntity.energy;

      final int energyStored = settableStorage.getEnergyStored();

      if (energyStored > 0) { // Draw energy bar
         //this.blit();
            // ToDo set blit
      }
    }

    @Override
    public void render(int mouseX, int mouseY, float partickelTicks) {
        this.renderBackground();
        super.render(mouseX, mouseY, partickelTicks);
        this.renderHoveredToolTip(mouseX,mouseY);

        // TODO zahlen werte anpassen
        int relMouseX = mouseX - this.guiLeft;
      int relMouseY = mouseY - this.guiTop;
      boolean energyBarHovered = relMouseX > 151 && relMouseX < 166 && relMouseY > 10 && relMouseY < 76;
      if (energyBarHovered) {
         String tooltip = new TranslationTextComponent(
               "gui." + NovusTechnica.MODID + ".energy",
               this.container.tileEntity.energy.getEnergyStored()
         ).getFormattedText();
         this.renderTooltip(tooltip, mouseX, mouseY);
      }


    }
}

 

I have absolutly no idea whats wrong so i really need your help Thank you very much for your support !!!!

latest.log

thanks mate now it works.

But how did you realize that i didn't register the defferdRegister, because i could figure it out form the log.

May be you could give me some insight so i can figure it out my self the next time.

and Thanks again for your time and great advise.
