Switch statement with World#getBlockState() to compare blocks not working (Constant Expression Required)

[MSpace-Dev]

Hey everyone,

 

So I am trying to make a switch statement to compare the block that I am looking at, to the blocks within my mod. Yet, when I try make my first case, I get Constant Expression Required error. I'm not sure how to fix this. All my blocks in my mod are declared as final variables.

Here are the two things I've tried so far:

 

switch (worldIn.getBlockState(pos).getBlock()) {
            case ModBlocks.my_mod_block :
                Utils.getLogger().info("mod block right clicked");
                break;
        }

switch (true) {
            case (worldIn.getBlockState(pos).getBlock() == ModBlocks.my_mod_block) :
                Utils.getLogger().info("mod block right clicked");
                break;
        }

ModBlocks.class

public class ModBlocks {
    public static final Block my_mod_block = new MyModBlock("my_mod_block", Material.WOOD);

    public static final Block[] BLOCKS = {
            my_mod_block
    };
}

 

Thanks!

switch statements only work on primitive types, Strings, enums & the wrapper objects for primitive types(These are special cased). Since Block does not fall into any of those categories, you can't switch on a field/method return of type Block. 

 

What are you actually trying to do here? Blocks have a method that is called when they are right-clicked.

Compare a bunch of blocks to the one I'm looking at.

Why? It looks like you're trying to add a right-click action to your block. That is not the way to do it.

Thanks, diesieben for the actual answer, exactly what I am looking for!

 

Leviathan, I want to see what block I am looking at with the item I am holding from my mod... Not trying to add right click action... (This item is a tool) I'm not that stupid.
