I want my event to be canceled when the player is in the end dimension, how?

@SubscribeEvent
    public void onPlayerInteract(PlayerInteractEvent.RightClickBlock evt) {
        // only handle right clicks on blocks
        // TODO: port for 1.9
//        if (evt.action != PlayerInteractEvent.Action.RIGHT_CLICK_BLOCK) {
//            return;
 
        BlockPos pos = evt.getPos();
        World world = evt.getWorld();
        IBlockState state = world.getBlockState(pos);
        Block block = world.getBlockState(pos).getBlock();
        
        // don't interact with vanilla egg blocks if configured
        if (RealmOfTheDragons.instance.getConfig().isDisableBlockOverride() && block == Blocks.DRAGON_EGG) {
            return;
        }
        
        // ignore non-egg blocks
        if (block != Blocks.DRAGON_EGG && block != BlockDragonBreedEgg.DRAGON_BREED_EGG) {
            return;
        }
        
        // deny action
        evt.setResult(Event.Result.DENY);
        
        // clear dragon egg block to avoid teleportation
        boolean setair = world.setBlockToAir(pos);
        
        // create dragon egg entity on server // put else
        if (!world.isRemote) { // this was inverted, i.e. evt.world.isRemote, but it should surely be this way
            EntityTameableDragon dragon = new EntityTameableDragon(world);
            dragon.setPosition(pos.getX() + 0.5, pos.getY() + 0.5, pos.getZ() + 0.5);
            dragon.getReproductionHelper().setBreeder(evt.getEntityPlayer());
            dragon.getLifeStageHelper().setLifeStage(EnumDragonLifeStage.EGG);  
            boolean spawn = world.spawnEntity(dragon);
            
            // set breed type (custom dragon egg only, otherwise use default breed)
            if (block == BlockDragonBreedEgg.DRAGON_BREED_EGG) {
                EnumDragonBreed breed = state.getValue(BlockDragonBreedEgg.BREED);
                dragon.getBreedHelper().setBreedType(breed);
            }
              spawn = true;     
        }
        
        if (world.provider.getDimensionType().equals(DimensionType.THE_END)) {
        	evt.setCanceled(true);
        }
    }
}

        if (world.provider.getDimensionType().equals(DimensionType.THE_END)) {
            evt.setCanceled(true);
        }

how do I arrange this exactly?

What specifically are you trying to cancel? If it's the entire thing in there wouldn't you just surround the entire thing with that if?

And wouldn't using:

 

 if (world.provider instanceof WorldProviderEnd) {
            evt.setCanceled(true);
        } 

 

Work a lot better?

SOLVED! Just gotta put the source code so I can help kids who would check this

public class DragonEggBlockHandler {

    @SubscribeEvent
    public void onPlayerInteract(PlayerInteractEvent.RightClickBlock evt) {
 
        BlockPos pos = evt.getPos();
        World world = evt.getWorld();
        IBlockState state = world.getBlockState(pos);
        Block block = world.getBlockState(pos).getBlock();
        
        if (world.provider.getDimensionType().getId() != 1) {
    	
        
        // don't interact with vanilla egg blocks if configured
        if (RealmOfTheDragons.instance.getConfig().isDisableBlockOverride() && block == Blocks.DRAGON_EGG) {
            return;
        }
        
        // ignore non-egg blocks
        if (block != Blocks.DRAGON_EGG && block != BlockDragonBreedEgg.DRAGON_BREED_EGG) {
            return;
        }
        
        // deny action
        evt.setResult(Event.Result.DENY);
        
        // clear dragon egg block to avoid teleportation
        world.setBlockToAir(pos);
        
        // create dragon egg entity on server // put else
        if (!world.isRemote) { // this was inverted, i.e. evt.world.isRemote, but it should surely be this way
            EntityTameableDragon dragon = new EntityTameableDragon(world);
            dragon.setPosition(pos.getX() + 0.5, pos.getY() + 0.5, pos.getZ() + 0.5);
            dragon.getReproductionHelper().setBreeder(evt.getEntityPlayer());
            dragon.getLifeStageHelper().setLifeStage(EnumDragonLifeStage.EGG); 
            
            // set breed type (custom dragon egg only, otherwise use default breed)
            if (block == BlockDragonBreedEgg.DRAGON_BREED_EGG) {
                EnumDragonBreed breed = state.getValue(BlockDragonBreedEgg.BREED);
                dragon.getBreedHelper().setBreedType(breed);
                
                } world.spawnEntity(dragon);       
            }
        }       
    }
}
