Solved Get location of impact from arrow

I have been trying to make a plugin that makes a 'portal gun'
Not really like those fancy ones that create portals but it simply fires and arrow and teleports you to it when it hits something.

I have this (found off another thread, modified quite a bit though):

Code:java

@EventHandler
public void arrowEvent(ProjectileHitEvent event) {
    if(event.getEntity() instanceof Arrow) {
        Arrow arrow = (Arrow)event.getEntity();
        Entity shooter = arrow.getShooter();
 
        if(shooter instanceof Player) {
            Player player = (Player)shooter;
            if (player.getItemInHand().getItemMeta().getDisplayName().equals("§1Portal Gun")) {
                if(player.getInventory().getItemInHand().getType().equals(Material.BLAZE_ROD)){
                Location loc = arrow.getLocation();
                player.teleport(loc);
            }
        }
        }
    }
    }

All this does is teleport the player one block higher but X and Z stay the same.
And, for firing the arrow(This method I made works for all my guns in the plugin):

Code:java

player.launchProjectile(Arrow.class).setVelocity(player.getLocation().getDirection().multiply(50));

So, does anyone know how to fix this?
I'm thinking from the first codebox I might just be getting the location of the wrong class?
I don't know!
Please help, I appreciate it

 

Try using the code from this thread and see what you can do with it.

Thank you for the reply!

I am fiddling around with that a bit, here is what I got:

Code:java

@EventHandler
private void onArrowHitBlock(ArrowHitBlockEvent event) {
Arrow arrow = event.getArrow();
Block block = event.getBlock();
Location loc = block.getLocation();
Entity shooter = arrow.getShooter();
if(shooter instanceof Player) {
    Player player = (Player)shooter;
    if (player.getItemInHand().getItemMeta().getDisplayName().equals("§1Portal Gun")) {
        if(player.getInventory().getItemInHand().getType().equals(Material.BLAZE_ROD)){
            player.teleport(loc);
        }
    }
    }
}

Currently, that does nothing?
If anybody knows how to fix this, that would be great

 

Make sure the event is registered in your main class, and add some debug statements to ensure that all of the if statements pass.

EDIT: Rather than using the ArrowHitEvent, try using the method using reflection, but like the author said be sure to put it inside of a Bukkit runnable with no delay.

Code:

//Inside of ProjectileHitEvent
World world = arrow.getWorld();
 
            net.minecraft.server.EntityArrow entityArrow = ((CraftArrow)arrow).getHandle();
 
            Field fieldX = net.minecraft.server.EntityArrow.class.getDeclaredField("e");
            Field fieldY = net.minecraft.server.EntityArrow.class.getDeclaredField("f");
            Field fieldZ = net.minecraft.server.EntityArrow.class.getDeclaredField("g");
 
            fieldX.setAccessible(true);
            fieldY.setAccessible(true);
            fieldZ.setAccessible(true);
 
            int x = fieldX.getInt(entityArrow);
            int y = fieldY.getInt(entityArrow);
            int z = fieldZ.getInt(entityArrow);
 
            Block block = world.getBlockAt(x, y, z);

EDIT: I fixed this! (Solved)
Working code:

Code:java

@EventHandler
public void onHit(ProjectileHitEvent event) {
if (event.getEntity() instanceof Arrow) {
if (event.getEntity().getShooter() instanceof Player){
Entity entity = event.getEntity();
BlockIterator iterator = new BlockIterator(entity.getWorld(), entity.getLocation().toVector(), entity.getVelocity().normalize(), 0, 4);
Block hitBlock = null;
 
while(iterator.hasNext()) {
hitBlock = iterator.next();
if(hitBlock.getTypeId()!=0) {
break;
}
}
 
LivingEntity liv = event.getEntity().getShooter();
Player p = (Player)liv;
if (p.getItemInHand().getItemMeta().getDisplayName().equals("§1Portal Gun")||p.getItemInHand().getItemMeta().getDisplayName().equals("§1Portal Bow")){
if(p.getInventory().getItemInHand().getType().equals(Material.BLAZE_ROD)||p.getInventory().getItemInHand().getType().equals(Material.BOW)){
//Projectile proj = (Projectile) event.getEntity();
int tpX = (int) hitBlock.getLocation().getX();
int tpY = (int) hitBlock.getLocation().getY();
int tpZ = (int) hitBlock.getLocation().getZ();
int tpyaw = (int) p.getLocation().getYaw();
int tppitch = (int) p.getLocation().getPitch();
Location loc = new Location(p.getWorld(),tpX,tpY,tpZ,tpyaw,tppitch);
p.teleport(loc);
}
}
}
}
}

Sorry, I don't quite understand, //Inside of ProjectileHitEvent
How to I put stuff inside an event? (Sorry, i'm a noob when it comes to bukkit)

But, I did get this going:

Code:java

@EventHandler
public void onHit(ProjectileHitEvent event) {
if (event.getEntity() instanceof Arrow) {
if (event.getEntity().getShooter() instanceof Player);
LivingEntity liv = event.getEntity().getShooter();
Player p = (Player)liv;
if (p.getItemInHand().getItemMeta().getDisplayName().equals("§1Portal Gun")) {
if(p.getInventory().getItemInHand().getType().equals(Material.BLAZE_ROD)){
Projectile proj = (Projectile) event.getEntity();
int tpX = (int) proj.getLocation().getX();
int tpY = (int) proj.getLocation().getY();
int tpZ = (int) proj.getLocation().getZ();
int tpyaw = (int) p.getLocation().getYaw();
int tppitch = (int) p.getLocation().getPitch();
Location loc = new Location(p.getWorld(),tpX,tpY,tpZ,tpyaw,tppitch);
p.teleport(loc);
}
}
}
}

This, unfortunately does around the same thing.
It does however run when an arrow is shot, just pushes the player backwards a bit.

How do you get the location of the arrow? or block it hit?

Thanks!
