[Solved] Java 8 Method Reference Operator NullPointerException

I'm trying to use this new operator: RenderingRegistry.registerEntityRenderingHandler(EntityMagic.class, RenderModProjectile::new); - yet Eclipse throws a NullPointerException at it for some reason, even though Eclipse is targeting Java 8. Anyone know why this is happening? The compiler settings in Eclipse are all set to 1.8, yet for whatever reason using RenderModProjectile::new doesn't seem to work.

There is no crash running Minecraft. Eclipse throws a NullPointerException trying to build the workspace.

 

Only thing I can find is this:

Internal compiler error: java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.ast.ReferenceExpression.isPotentiallyCompatibleWith(ReferenceExpression.java:

962)

Updating Eclipse just seems to throw a new error, saying The target type of this expression must be a functional interface. This doesn't make any sense because other people registering entities this way don't seem to get any issues. Is it still an issue with Eclipse even though it's updated? Or perhaps it's an issue with my Render class?

I'm still trying to figure out a way around this:

 

RenderingRegistry.registerEntityRenderingHandler(EntityProjectile.class, RenderProjectile::new);

 

This throws the following error: The target type of this expression must be a functional interface

 

I don't understand how this error is getting thrown when other people are using the same exact code and is working perfectly fine for them. I'm still assuming it's an issue with Eclipse somehow, but I don't understand why Eclipse would be throwing this error either, even after updating it. Not too sure if this is an issue with Forge or not, but hopefully I can at least get pointed into the right direction.

new RenderProjectile()

?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Yup, I ultimately just used this as a test because the super constructor only requires a RenderManger parameter. Ideally I would use something similar to RenderSnowball, which I'm currently testing out now. I feel like this should fix up the issue, and is just an error on Eclipse's part hopefully.

    • Ok yeah I think this might be where the problem starts. For starters, I think you can get rid of your RecipeType impl and make it a static constant instead. I'm not 100% sure this will fix it but it's posssible. RuneInscribingRecipe public class RuneInscribingRecipe implements Recipe<SimpleContainer> { public static final RecipeType<RuneInscribingRecipe> RECIPE_TYPE = new RecipeType<>(){}; // .... @Override public RecipeType<?> getType() { return RECIPE_TYPE; } // .... } RuneInscriberMenu private Optional<RecipeHolder<RuneInscribingRecipe>> getCurrentRecipe() { SimpleContainer inventory = new SimpleContainer(2); inventory.setItem(BASE_INPUT_SLOT, this.inventory.getStackInSlot(BASE_INPUT_SLOT)); inventory.setItem(TEMPLATE_INPUT_SLOT, this.inventory.getStackInSlot(TEMPLATE_INPUT_SLOT)); List<RecipeHolder<RuneInscribingRecipe>> list = this.blockEntity.getLevel().getRecipeManager().getRecipesFor(RuneInscribingRecipe.RECIPE_TYPE, inventory, this.blockEntity.getLevel()); if (list.isEmpty()) { return Optional.empty(); } return Optional.of(list.get(0)); }   Also, this here is a little suspicious where you're getting the `this.inventory.getStackInSlot` calls. I'd try and make sure those are what you expect they are with either a Debug line in IDE or print statement SimpleContainer inventory = new SimpleContainer(2); inventory.setItem(BASE_INPUT_SLOT, this.inventory.getStackInSlot(BASE_INPUT_SLOT)); System.out.printf("CHECKING BASE INPUT OF RECIPE: %s\n", this.inventory.getStackInSlot(BASE_INPUT_SLOT)); inventory.setItem(TEMPLATE_INPUT_SLOT, this.inventory.getStackInSlot(TEMPLATE_INPUT_SLOT)); System.out.printf("CHECKING TEMPLATE INPUT OF RECIPE: %s\n", this.inventory.getStackInSlot(TEMPLATE_INPUT_SLOT)); ^ See what the result of those print statements are, make sure they're right
    • Upon testing again after adding them, the game still doesn't crash however the resource packs are still unfortunately broken.
    • Hi! Can someone please point me to the correct FAQ or place? I'm not able do DuckDuckGo myself out of this one. As you can hopefully see, chunks are not rendered. I run a forge server, fresh install on a linux VM. Curseforge on the Win11 client with Embeddium, Oculus and Unbound shader. No mods. Forge 47.2.23 on server & client.  No errors, no crashes, no apparent CPU or RAM issues with the VM. This screenshot was captured while creative, but the same happens when flying in survival. Waiting (floating) for a few minutes sooner or (often) later, lets the missing chunks appear. Usually takes 5-10 minutes.  When on a local game, the chunks appear slowly, but they do appear without pause.   This must be something simple, obvious, but I can't find the correct "search words" to find my way out. "Chunks not loading / rendering" didn't help. Browsing several forums neither. 
    • This is the Forge forums. We only support Forge here. Read the FAQ
    • 1.The game doesn't crash, everything seems normal, but when i insert the designated items into the block entity, the result item does not show up. 2.Yes, I'm using a custom menu, here's the source code:
