Solved NoSuchMethod Error :S

Hey forum,
uhm I've been having some trouble getting the shooter of an arrow. I tried using EntityDamageByEntityEvent and ProjectileHitEvent, but I get a similar error each time.

Here is my code:

Code:java

 
@EventHandler
public void ArrowHit(ProjectileHitEvent e) {
if(e.getEntity().getShooter() instanceof Player) {
Player p = (Player) e.getEntity();
Player k = (Player) e.getEntity().getShooter();
if(p instanceof Player) {
if(arrowkill.contains(p.getName())) {
k.getInventory().addItem(new ItemStack(Material.ARROW));
k.sendMessage(ChatColor.GOLD + "[OITC] " + ChatColor.RED + "You killed " + p.getName() + ", good job!");
 
}
return;
}
}
 

And here is my stacktrace

Code:

Line 212 is

Code:java

if(e.getEntity().getShooter() instanceof Player) {

Anyone able to help a bit?

 

can you give the following information:
The craftbukkit version the server is running?
and
The version of craftbukkit you using to compile plugin?

 

ferrybig
Server is using some version of craftbukkit 1.7.2
And I'm using bukkit-1.7.2-R0.3-20140202.193209-23 to compile the plugin.

 

what exact version of bukkit are you using to compile the plugin and running the server, what build number?

 

I don't remember.
Edit:
"CraftBukkit version git-Bukkit-1.7.2-R0.2-3-g530fcb7-b2982jnks (MC: 1.7.2) (Implementing API version 1.7.2-R0.3-SNAPSHOT"

ferrybig
I'm using bukkit for compiling it in eclipse. Should I try using craftbukkit instead?

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

 

can you try to update them both to the latest beta version,
So your server will be craftbukkit http://dl.bukkit.org/downloads/craftbukkit/view/02535_1.7.2-R0.3/
and you will be compiling with http://dl.bukkit.org/downloads/bukkit/view/02534_1.7.2-R0.3/

 

phildachil
Do you have any other plugins on your server with the same package-class names?

 

First of all on line #5, event.getEntity() in ProjectileHitEvent returns a Projectile object. You shouldn't cast that to a Player.

Line #7 will always run because you just cast the projectile into a player.

 

alex123099
No I'm testing it on a server with just this plugin
Jombi
So because ProjectileHitEvent is not specific to another entity getting hit, should I use EntityDamageByEntityEvent?

 

phildachil Yes

Code:java

 
  public void onEntityDamage(EntityDamageByEntityEvent event){
    if(event.getDamager() instanceof Arrow){
      Arrow arrow = (Arrow) event.getDamager();
      if(arrow.getShooter() instanceof Player){
        Player shooter = (Player) arrow.getShooter();
 
      }
    }
  }

 

Jombi
Tried this code:

Code:java

 
@EventHandler
public void ArrowHit(EntityDamageByEntityEvent e) {
    Player p = (Player) e.getEntity();
    Arrow a = (Arrow) e.getDamager();
    Player k = (Player) a.getShooter();
    if((p instanceof Player) && k instanceof Player) {
        if(arrowkill.contains(p.getName())) {
            k.getInventory().addItem(new ItemStack(Material.ARROW));
            k.sendMessage(ChatColor.GOLD + "[OITC] " + ChatColor.RED + "You killed " +                    p.getName() + ", good job!");
        }
    }
}
 

Code:

at me.phildachil.oitc.OITC.ArrowHit(OITC.java:214) ~[?:?]

Still won't work.

 

phildachil
Check if e.getEntity() instance of Player and if e.getDamager() instance of Arrow

 

phildachil

I ninja'd my last post as you replied. Try that and let us know if it works. Also, it would be helpful if you pasted the full stacktrace when there is a problem.

 

It still doesn't work >_>

Nope didn't work.

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

 

.getShooter() on Arrow is deprecated in Bukkit. Instead, compile with CraftBukkit rather than just normal bukkit and try this:

Code:java

Player k = (Player) ((CraftArrow) a).getShooter();

 

Errm, you just need to update Craftbukkit on the server that you are testing on.

ProjectileSource is a recent API addition.

CraftArrow can't be resolved to a type

Woah, that worked. Thanks!
