"Throw" TNT?

I am trying to make the player throw (launch in the direction he is facing) primed tnt. It doesn't have to go on forever, but pretty far. I'm guessing it has to do with velocity? So far this is the direction i'm going with my event:

Code:

@EventHandler
    public void onPlayerInteract(PlayerInteractEvent event2){
    Player p = event2.getPlayer();
    if(event2.getPlayer().getItemInHand().getType() == Material.TNT);
        // insert code here
    }
}

Thanks for the help.

 

remove TNT, spawn TNTPrimed and tntentity.setVelocity(Vector)

 

Could you help me out with vectors, i have never really experimented with them before.

 

To get the direction the player is looking at (afaik) player.getLocation().getDirection(). I go as far as that, as I do not fully get minecrafts physics myself

 

Easier and better way would be to cancel tnt placement, then drop tnt block entity with world.dropItem, set the velocity, once it hits something, get the entity location and spawn primed tnt.

Pseudo alot? o_o

EDIT: Maybe just check if player right clicks with tnt in his/her hand, and do rest of the stuff, instead of cancelling tnt placement... it would just fail.

 

Ok so i have a bit of the code down... i just need help with the simplest part. I need to reference the tnt.

Code:

TNTPrimed tnt = (TNTPrimed) // what to put here?
          tnt.setVelocity(p.getLocation().getDirection().normalize().multiply(2));

This may help, just alter it to not fire kittens

 

Oh wait, i figured it out. Unfortunately, it fires tnt every time i right click... anything. When i tried putting "else" in the code it said to delete the token :X

Code:

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event2){
    Player p = event2.getPlayer();
    if(event2.getPlayer().getItemInHand().getType() == Material.TNT);
        p.getInventory().removeItem(new ItemStack(Material.TNT, 1));
        TNTPrimed tnt = (TNTPrimed) p.getWorld().spawn(p.getLocation(), TNTPrimed.class);
        tnt.setVelocity(p.getLocation().getDirection().normalize().multiply(2));
        }
        else { //says delete token
            p.sendMessage(ChatColor.RED + "You need to be holding TNT");
          }
    }
}

 

world.spawnEntity(EntityType)?

 

I fixed it, but now a new problem appears (yippie!). Whenever i right or left click, it performs the event twice.. so it throws two tnt and takes 2 tnt. Also, if you don't have tnt then it sends you two messages saying You need to be holding TNT. :/

P.S and i only want it on left clicks, not right clicks...

 

Im on my phone now, so I cant show code, but before you check item in hand, do

Code:

if(event2.getAction().equals(Action.RIGHT_CLICK_AIR)){ 

Also when you check item in hand, it end with ;
Replace it with {

That's better, can i make it left click though?

Anybody know why the event is performed twice?

Yep, got that

 

Just change RIGHT to LEFT to make it shoot when left clicked (DUHH!)
Show me your code, it shouldnt be launching twice.

 

Awesome! On to the next thing, a cooldown! Can anybody help with this? I am trying to prohibit the player from rapidly left clicking.

 

ArrayLists and scedulers. wiki.bukkit.org/Scheduler_Programming

Code:java

ArrayList<String> cooling = new ArrayList<String>();
// When letting them cool down
final String name = event.getPlayer().getName();
cooling.add(name);
Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable()
{
    public void run()
    {
        cooling.remove(name);
    }
}, cooldown_in_seconds*20L);

 

Well, you ended your if statement with a semicolon, so that won't work.

 

I also ended me and woobie's conversation by saying " Yep, got that"

 

I have the perfect code for this:

HERE YOU GO:

Code:JAVA

if(event.getAction() == Action.RIGHT_CLICK_AIR){
if (player.getItemInHand().getType() == Material.TNT) {
//Frag Grenades
final Item grenade = event.getPlayer().getWorld().dropItem(player.getEyeLocation(), new ItemStack(Material.TNT));
grenade.setVelocity(event.getPlayer().getEyeLocation().getDirection());
player.getInventory().removeItem(grenade.getItemStack());
Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
@Override
public void run() {
grenade.getWorld().createExplosion(grenade.getLocation(), 4.0F, false);
}
grenade.remove();
}
}, 60L);
event.setCancelled(true);
}
}
 
//So the explosion doesn't break blocks but still damages the player:
 
@EventHandler
public void onGrenadeExplode(EntityExplodeEvent event){
Entity entity = event.getEntity();
if (entity == null) {
event.blockList().clear();
}
}

WAIT FOR IT.................

 

The codes perfect, except for one thing. The remove statement on line 12 requires an "identifier" and i have not idea what it's talking about

 

it just removes the entity so players can pick it up again.

 

I know, but it has that notorious red squiggly line beneath it giving me an error. Also, the tnt does not explode D: I must say it throws alot better and smoother.

 

what error?
Also are you using the scheduler right? is this in you main class or separate?

 

It would be better to set to it to air rather than cancel the placement.

 

The error says " Syntax error on token "remove", Identifier expected after this token "
Separate class. Not sure how i would put it in the Main.

 

Then in the scheduler change "plugin" to "this"

Also did you ad the "();" to the end of "remove"?

 

AHH more errors :X For the first thing, i changed it to "this" and then another error appeared on the scheduleSyncDelayedTask. And for the second thing, yes there is a () after the remove.

Heres the error i am getting in the console.

After seeing this, I was intrigued so I decided to test this bit of code out. I used the code below but I did not get any results, no errors, no effects.

Any ideas on a fix?

Code:JAVA

@EventHandler
public void TntShoot(PlayerInteractEvent e){
Player p = e.getPlayer();
if(!p.isOp()) {
if(e.getAction().equals(Action.RIGHT_CLICK_AIR)) {
if(e.getPlayer().getItemInHand().getType() == Material.STICK) {
TNTPrimed tnt = (TNTPrimed) p.getWorld().spawn(p.getLocation(), TNTPrimed.class);
tnt.setVelocity(p.getLocation().getDirection().normalize().multiply(2));
}
else {
p.sendMessage(ChatColor.RED + "Error: stick not held");
}
}
}
}

 

Could you post you code or if you don't want it public, pm me?

 

Sure thing (btw it's basically your code )

Code:

import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.Plugin;
 
public class PlayerInteract implements Listener {
    public static Main plugin;
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event){
    Player p = event.getPlayer();
    if(event.getAction() == Action.LEFT_CLICK_AIR){ //<--- changed to left click
        if (p.getItemInHand().getType() == Material.TNT) {
        final Item grenade = event.getPlayer().getWorld().dropItem(p.getEyeLocation(), new ItemStack(Material.TNT));
        grenade.setVelocity(event.getPlayer().getEyeLocation().getDirection());
        p.getInventory().removeItem(grenade.getItemStack());
        Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() { // "this" doesn't seem to work
   
            @Override
            public void run() {
                grenade.getWorld().createExplosion(grenade.getLocation(), 4.0F, false);
                }
            grenade.remove(); //<---- error on remove
            }, 60L);
        event.setCancelled(true);
        }
    }
}
        @EventHandler
        public void onGrenadeExplode(EntityExplodeEvent event){
        Entity entity = event.getEntity();
        if (entity == null) {
        event.blockList().clear();
        }
    }
}

edit: Wait did you mean the whole .jar?
