Launch Fishing Bobber

How can I launch a fishing bobber from a player when they aren't holding a fishing rod (via a command, specifically)? I tried player.launchProjectile(Fish.class), however it is giving me errors in console saying "Projectile not supported." Anyone know how I can fix this?

 

Maybe try spawning it into the world and setting the velocity and the shooter?

 

Hmm.. I've briefly looked up fishing hooks and they like don't seem to exist.. Well, a workaround to this issue would be to spawn the entity in the world:

Code:

Entity hook = player.getWorld().spawnEntity(player.getEyeLocation(), EntityType.FISHING_HOOK);
hook.setVelocity(new Vector(player.getDirection()).multiply(2)); // Sets the velocity to where the player is looking and multiplies that by 2, because it may be too slow. You can fiddle around with that number to your liking.

 

The_Doctor_123 yes they do: http://jd.bukkit.org/rb/apidocs/org/bukkit/entity/Fish.html

They're called "Fish"?! That's kind of stupid.. they should be called Fishing Hooks..

 

chasechocolate The_Doctor_123 That won't work. Bukkit doesn't like it when fishing hooks are manually spawned.

Code:java

net.minecraft.server.v1_6_R2.World nmsWorld = ((CraftWorld) player.getWorld()).getHandle();
EntityFishingHook nmsHook = new EntityFishingHook(nmsWorld, ((CraftPlayer) player).getHandle());
 
nmsWorld.addEntity(nmsHook);

However, the bobber disappears after being launched. Perhaps someone knows how to fix this?

 

In the default fishing rod code, this line:

Code:java

 
  if (this.owner.dead || !this.owner.isAlive() || itemstack == null || itemstack.getItem() != Item.FISHING_ROD || this.e(this.owner) > 1024.0D) {
                    this.die();
                    this.owner.hookedFish = null;
                    return;
                }
 

prevents a fishing hook from existing when a player's item in hand is not a fishing rod...
however.... you can override the l_() method, just copy and paste the code from

https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityFishingHook.java

and remove

Code:java

 itemstack.getItem() != Item.FISHING_ROD 

from the if statement .

 

dillyg10 yeah, I figured it out a few hours ago, (I just created a custom class that extends EntityFishingHook), I'll post it when I get back on my computer.

xWatermelon dillyg10 here's how I did it:

Code:java

public class FishingLine extends EntityFishingHook {
    private Item item;
 
    public FishingLine(Player player, Item item){
        super(((CraftWorld) player.getWorld()).getHandle(), ((CraftPlayer) player).getHandle());
 
        this.item = item;
    }
 
    @Override
    public void l_(){
        if(item != null){
            ItemStack hand = this.owner.bx();
            boolean shouldRemove = false;
 
            if(this.owner.dead || !(this.owner.isAlive())){
                shouldRemove = true;
            }
 
            if(hand == null){
                shouldRemove = true;
            } else {
                if(hand.getItem() != item){
                    shouldRemove = true;
                }
            }
 
            if(this.e(this.owner) > 1024.0D){
                shouldRemove = true;
            }
 
            if(shouldRemove){
                super.die();
                super.owner.hookedFish = null;
            }
        }
    }
 
    public void spawn(Location loc){
        net.minecraft.server.v1_6_R2.World nmsWorld = ((CraftWorld) loc.getWorld()).getHandle();
 
        nmsWorld.addEntity(this);
        this.setPosition(loc.getX(), loc.getY(), loc.getZ());
    }
}

Entity hook = player.getWorld().spawnEntity(player.getEyeLocation(), EntityType.FISHING_HOOK);
hook.setVelocity(new Vector(player.getDirection()).multiply(2)); // Sets the velocity to where the player is looking and multiplies that by 2, because it may be too slow. You can fiddle around with that number to your liking.
Dosen't work because you cant just get a player's velocity. You have to get their location and then their velocity.
player.getLocation().getVelovity();

 

It gives me an error on this lines:

Code:Java

 
ItemStack hand = this.owner.bx();
if(hand.getItem() != item){

naorpeled Are you including Craftbukkit and I believe it's .by(), however that's going off my memory from earlier today.

 

Yes, I do include Craftbukkit and BukkitAPI.
Edit: I fixed it.
but now, how do I use it to launch a fishing hook?

 

How about trying this:
Player launches fishing rod
You get nearby entities (the bobber)
You set the velocity of the bobber
