Nether Star Projectile Not Working

Hi, I am trying to make a ninja kit and what could be better than to be able to shoot nether stars? Well, I tried to use the same code that I used to shoot ice blocks for an ice kit I made but it doesn't work. It gives me an Event Exception on line 36 of the following code.

Code:java

@EventHandler
public void onInteract(PlayerInteractEvent e) {
final Player p = e.getPlayer();
Vector vec = p.getLocation().getDirection();
if ((e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) && p.getItemInHand() != null) {
if (p.getItemInHand().getType() == Material.NETHER_STAR) {
FallingBlock fb = p.getWorld().spawnFallingBlock(p.getEyeLocation(), Material.NETHER_STAR, (byte) 0x0);//line 36 
fb.setVelocity(vec.multiply(5.0D));
}

yes, the brackets are wrong, there is other code after this that works fine and I didn't want to take up space by pasting the other code. Anyone have a solution to this? Maybe you can't make Nether stars falling blocks because it isn't even a block?

 

Well, you know what would be useful is the Event Exception and an indicator of which line is 36.

 

LOL my first time posting I did have that but then I edited my code and forgot to put that info back inXD My bad line 36 is line 7 on the code posted above. I will edit thisXD

 

A nether star isn't a block, so it can't be spawned as a falling block.

(At least as far as I've tested...)

 

hmm I will experiment with dropping the item instead of making it a falling block. turqmelon

Alright, I came up with the following code that works pretty well.

Code:java

Vector vec = p.getLocation().getDirection();
 
Item drops = p.getWorld().dropItem(p.getLocation(), p.getItemInHand());
drops.setVelocity(vec.multiply(30.0D).normalize());

Now, there are 2 problems with this. If the player is holding more than one nether star, let's say 10 of them, then the player will shoot 10 nether stars (bad idea...). Also, I would like them to be removed when they hit the ground. How would I check when the nether star hits the ground? Thanks

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Use a repeating task tick- check if drops.isOnGround() (Might be something else) and if so, remove the item.

 

lol there was an isOnGround() method? woopsXD. I beleive that will solve my problem but I will have to test it tomorrow since I'm on my phone. Do you have a way to make it only shoot one nether star instead of however many you have in your hand? I just did /i netherstar and found out I was shooting stacks of netherstarsXD. I do not want that happening.

 

Do you mean like a cooldown?

 

no not a cooldown. I know how to make cooldowns. When I went to my server to test the plugin, I did /i netherstar and when I right clicked, I started shooting STACKS of netherstars. I want it to shoot only one nether star regardless of how many you have in your hand. Would you like me to post a video?

Because you drop the whole dang thing in the code. (p.getItemInHand() returns an ItemStack thus if the player has 64 nether stars... It would return the ItemStack with the Material.NETHER_ STAR and a quantity of 64)

 

so should I just create my own Item Stack with only 1 nether star and make the player drop that instead?

Yes...
