Would I Use getVelocity() For This Situation?

Hi. I am making a plugin like codename_Bs boulder toss ability in arena. I am having trouble figuring out how to make a block fly through the air. I was doing some research and was wondering Would i use

Code:java

BlockDispenceEvent.getVelocity()

Code:java

BlockDispenceEvent.setVelocity(Vector vel)

and

Code:java

BlockDispenceEvent(Block block, ItemStack dispensed, Vector velocity)

I think these are the things i need to launch a block in the air but not sure :/ Any ideas?

 

mkezar
Im pretty sure for blocks to fly through the air, it needs to either be sand or gravel. Recently thou mojang added the falling sand entities, which is most likely how these are being done. You would need to get the block that you want to fly, turn it into a sand entity and then launch it some how. You might be able to use the velocity after you create the entity.

 

Ill fetch a code for you,

 

mkezar You'd need to spawn a falling block, set its type to the block you want, and set its velocity. You'd also need to listen to some events involving falling blocks, like when they hit the ground, and other things.

 

Here yeah go:

Code:java

 
@EventHandler
public void onSpawnFallingBlock(PlayerInteractEvent event){
Player p = event.getPlayer();
 
if(event.getAction() == Action.RIGHT_CLICK_AIR){
if(event.getItem().getType() == Material.STICK){
Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
                FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.DIAMOND_BLOCK, (byte)0);
 
}
}
 
}
 

 

mrgreen33gamer so would i just paste this into my class? or do i need to import some stuff

mrgreen33gamer ok so i added these imports

Code:java

import org.bukkit.block.BlockFace;
import org.bukkit.entity.FallingBlock;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerInteractEvent;

ik there is more but they have more than 2 to choose from and i dont want to import the wrong thing

mkezar You cannot import the wrong class. If you import the wrong class you'll get an error for not fitting the right object-type. then just choose the other class to import.
I think you will do fine if you alsoways import org.bukkit.XYZ.. other classes are often from apache, google or java.. which you don't need in most of the cases.

 

mrgreen33gamer Ok lol heres my code. some stuff got deprecated and is not working it does not show up in the /plugins heres the code finished

Code:java

package me.mkezar.VariousProjects;
 
import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.FallingBlock;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
 
public class BoulderToss {
 
    @EventHandler
    public void onSpawnFallingBlock(PlayerInteractEvent event){
    Player p = event.getPlayer();
 
    if(event.getAction() == Action.RIGHT_CLICK_AIR){
    if(event.getItem().getType() == Material.STICK){
    Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
                    FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.DIAMOND_BLOCK, (byte)0);
 
    }
    }
 
    }
 
}
 

 

Here:

Code:java

package me.mkezar.VariousProjects;
 
import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.FallingBlock;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
 
public class BoulderToss implements Listener{
 
@EventHandler
public void onSpawnFallingBlock(PlayerInteractEvent event){
Player p = event.getPlayer();
 
if(event.getAction() == Action.RIGHT_CLICK_AIR){
if(event.getItem().getType() == Material.STICK){
Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.DIAMOND_BLOCK, (byte)0);
 
}
}
 
}
 
}

 

mrgreen33gamer what do i import for Listener? it gives me the red squiggely line underneath it. do i import

Code:java

import org.bukkit.event;

 

Just import the Listener, and make sure you put this in your onEnable in your Main Class:

Code:java

 
this.getServer().getPluginManager().registerEvents(new BoulderToss(this), this);
 
new BoulderToss(this);
 

And here is your class again:

Code:java

package me.mkezar.VariousProjects;
 
 import org.bukkit.Location;
 import org.bukkit.Material;
 import org.bukkit.block.BlockFace;
 import org.bukkit.entity.FallingBlock;
 import org.bukkit.entity.Player;
 import org.bukkit.event.EventHandler;
 import org.bukkit.event.block.Action;
 import org.bukkit.event.player.PlayerInteractEvent;
 
 public class BoulderToss implements Listener{
 
 YourMainClass main;
 public BoulderToss(YourMainClass instance){
 main = instance;
 }
 
 @EventHandler
 public void onSpawnFallingBlock(PlayerInteractEvent event){
 Player p = event.getPlayer();
 
 if(event.getAction() == Action.RIGHT_CLICK_AIR){
 if(event.getItem().getType() == Material.STICK){
 Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
 FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.DIAMOND_BLOCK, (byte)0);
 
 }
 }
 
 }
 
 }
 

 

I get this huge error when loading. It says it cant find the main class

mrgreen33gamer about the post above heres what my plugin

looks like View attachment 19269

This is BoulderToss.java

Code:java

package plugins.mkezar;
 
import org.bukkit.plugin.java.JavaPlugin;
 
 
public class BoulderToss extends JavaPlugin {
    @Override
    public void onEnable() {
        this.getServer().getPluginManager().registerEvents(new BoulderTossListener(), this);
    }
 
}
 

and this is BoulderTossListener

Code:java

package plugins.mkezar;
 
import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.FallingBlock;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
 
public class BoulderTossListener implements Listener {
 
    @EventHandler
    public void onSpawnFallingBlock(PlayerInteractEvent event) {
        Player p = event.getPlayer();
 
        if(event.getAction() == Action.RIGHT_CLICK_AIR) {
            if(event.getItem().getType() == Material.STICK) {
                Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
                FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.DIAMOND_BLOCK, (byte)0);
            }
        }
    }
}

PM me your whole code please. And you plugin.yml

 

mrgreen33gamer yes sir

mrgreen33gamer ok i pmed u

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

 

You need an onEnabled() method to register the events

 

Ok. I got this working!!! But. 1 thing. It drops the block on me. I want it so it gets my line of sight and instead of dropping, its a projectile. Any ideas? here is what i have for it making a block spawn above my head.

Code:java

Location loc = p.getLocation().getBlock().getRelative(BlockFace.UP,20).getLocation().add(0.5, 0, 0.5);
                FallingBlock entity = loc.getWorld().spawnFallingBlock(loc, Material.STONE, (byte)0);

so i want it to throw the block where im looking, not dropping in on my head.
Thank you!!!

 

mkezar
Get the yaw and pitch and send the block going in that direction.
