[Solved] Java 8 Method Reference Operator NullPointerException

[TheXFactor117]

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)

That's what I figured - I was looking around on stackoverflow and they made it sound like it's just a bug within Eclipse.

 

Anyways, sorry to bother y'all with a non-Forge related question.

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?

Here it is.

I just don't get why it's throwing errors - I guess it has to be an issue with Eclipse, though I just updated to the most recent version.

[TheXFactor117]

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()

?

[TheXFactor117]

Would the fact that RenderLiving, for example, being an abstract class be the cause for it throwing this error?

[TheXFactor117]

Here's the render class. It's using 1.10, though error is same for both 1.9.4/1.10.

 

I actually should probably not use RenderTippedArrow, though changing this up still results in the same error.

[TheXFactor117]

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.

Everything's working now. Thanks for all the help.

 

For anyone interested in the render class / registry, there they are.
