onProjectileHitEvent problem

So, I have been making this plugin that would act like the smoke grenades in the game Cops N' Crims on Hypixel. All it does is when an egg hits a block it will save the blocks into an array of blocks and spawn in a bunch of flowers on top of each other. I'm fairly certain there is no problem with the flower placement, but the issue is when the onProjectileHitEvent is fired it gives me an error. Here's my code for the event

Code:

    static Block[] block;
   
    @EventHandler
    public void onProjectileHit(ProjectileHitEvent event) {
        if(event.getEntity().getType() == EntityType.EGG) {
            Egg egg = (Egg) event.getEntity();
            ItemStack grenade = (ItemStack) egg;
            ItemMeta grenadeMeta = grenade.getItemMeta();
            if(grenadeMeta.getDisplayName().equals("Smoke Grenade")) {
                    block[0] = (Block) egg.getLocation().getBlock();
                    block[1] = block[0].getLocation().add(0,1,0).getBlock();
                    block[2] = block[0].getLocation().add(0,2,0).getBlock();
                    block[3] = block[0].getLocation().add(0,3,0).getBlock();
                    block[4] = block[0].getLocation().add(1,0,0).getBlock();
                    block[5] = block[0].getLocation().add(2,0,0).getBlock();
                    block[6] = block[0].getLocation().add(3,0,0).getBlock();
                    block[7] = block[0].getLocation().add(0,0,1).getBlock();
                    block[8] = block[0].getLocation().add(0,0,2).getBlock();
                    block[9] = block[0].getLocation().add(0,0,3).getBlock();
                    block[1].setType(Material.YELLOW_FLOWER);
                    block[2].setType(Material.YELLOW_FLOWER);
                    block[3].setType(Material.YELLOW_FLOWER);
                    block[4].setType(Material.YELLOW_FLOWER);
                    block[5].setType(Material.YELLOW_FLOWER);
                    block[6].setType(Material.YELLOW_FLOWER);
                    block[7].setType(Material.YELLOW_FLOWER);
                    block[8].setType(Material.YELLOW_FLOWER);
                    block[9].setType(Material.YELLOW_FLOWER);
                    Main.main.startTimer();
            }
        }
    }

And here's the error in console:

Code:

[18:35:35 ERROR]: Could not pass event ProjectileHitEvent to Grenade v1.0
org.bukkit.event.EventException

Any help would be awesome! Thanks so much!!

 

@AcePilot10 Please put the latest.log (found in the logs folder) in a pastebin.

@AcePilot10 First of all, read this. Secondly, you're casting to Egg on this line

You have to check that the Entity is actually an Egg before you cast!

 

MY EYES!

Code:

for(int i = 0; i < 9; i++)
{
    block[i].setType(Material.YELLOW_FLOWER);
}

 

@ColonelHedgehog I hate you xD but thanks that helps alot.

@nverdier i will test that you

Thanks so much for the responses guys! I love youuuu!!!!!!!!!!!!

I threw in an if statement and that doesn't seem to be the problem :/
