getBlock returns wrong type

[Tieso2001]

I'm making a mod where if I right click with an empty hand on sand, it gives me a item. I use the onPlayerInteract(PlayerInteractEvent.RightClickBlock event) to do this, but when I try to get the block which is right clicked it returns the wrong type.

 

Block block = event.getWorld().getBlockState(event.getPos()).getBlock();

 

It says incompatible types:

required: jdk.nashorn.internal.ir.Block

found: net.minecraft.block.Block

 

The whole class:

@SubscribeEvent
    public static void onPlayerInteract(PlayerInteractEvent.RightClickBlock event) {
        ItemStack hand = event.getItemStack();
        Block block = event.getWorld().getBlockState(event.getPos()).getBlock();
        if (hand.isEmpty() && event.getEntityPlayer().isSneaking()) {
            if (ImmutableSet.of(Blocks.SAND).contains(block)) {
                if (event.getWorld().isRemote) {
                    event.getEntityPlayer().swingArm(event.getHand());
                } else {
                    if (Math.random() < 0.8)
                        event.getEntityPlayer().dropItem(new ItemStack(Items.STICK), false);
                }
                event.setCanceled(true);
                event.setCancellationResult(EnumActionResult.SUCCESS);
            }
        }
    }

 

How do I solve this problem?

 

This is in 1.12.2 btw.

Which Block did you import?

just do if(block==Blocks.SAND)

[Tieso2001]

What do you mean by which Block I imported?

[Tieso2001]

Okay I will use if(block == Blocks.SAND) but I still have the error that the types are incompatible

Which Block class did you import?

Which class called “Block” (from one of the external libraries) did you import into the class that you are writing? If it’s not “net.minecraft.block” that’s your problem.

[Tieso2001]

Thanks! I accidentally imported the jdk.nashorn class instead of the minecaft one.

You need to know basic Java before you make a mod. Even spending 1-2 hours reading or watching a good tutorial helps immeasurably. Sorry to be blunt with you, but this is an absolute pre-requisite.

On the upside you now know one of the causes of this error, and know how to fix it.

Usually googling an error you got should get you an decent explanation. This problem deals with such basic Java that no one appears to have asked this question on google (the error is pretty self explanatory to someone with basic Java knowledge), so this advice doesn’t apply in this specific case, but it is good advice in general!

Happy Modding!

Thanks for the advice, I know basic java and I have made mods before, but this was something that I just didn't realise and thought that it was some other mistakes than importing the wrong class. Also I tried googling but that didn't really got me anywhere so I decided to see if someone could help me here. Anyways thanks for your help.

If you don't recognize a thing, you probably did something wrong. In this case, figure out why "jdk.nashorn" is being referenced.
