Portal Effects

Does anyone know how to give the 'nether portal' effect?

 

The best way would probably be to give the player the nausea potion effect.

Yes, that is a good idea, it came to mind. But how would you make the players screen to slightly glow purple, like it does when you enter a portal.

 

I have no idea... maybe try spawning a portal block where the player is and set it to air after a scheduler happens?

 

KeybordPiano459
Okay, I'll try that

 

What if the player is moving?

 

Woobie
I think I'll use PlayerMoveEvent. Whenever player moves it will create a new portal

 

It would look a bit weird to have portal blocks following you.

 

I dunno, I haven't thought this through at all Also, if you can think of anything better, go ahead

This is what I've got so far, it makes a trail of portals blocks follow you, but then they dissapear. so no landscape griefing.

PHP:

    @EventHandler
    public void CakePlace(PlayerMoveEvent e) {
        Location l = e.getPlayer().getLocation();
        World w = l.getWorld();
        final Block b = w.getBlockAt(l);
        b.setType(Material.PORTAL);
        int taskID = Bukkit.getServer().getScheduler().scheduleAsyncRepeatingTask((Plugin) this, new Runnable() {
 
            public void run() {
                b.setType(Material.AIR);
 
 
 
            }
        }, 40L, 0);
 
    }

Sadly, I keep getting this error every time I move:

Line 24 pls.
EDIT: You are using repeating task, change it to delayed task!
---------------

Not sure if this exists

Code:

player.getWorld().playEffect(player.getLocation(), Effect.PORTAL); 

 

Woobie
It doesn't exist Heres line 24

PHP:

        int taskID = Bukkit.getServer().getScheduler().scheduleAsyncRepeatingTask((Plugin) this, new Runnable() {

Nobody can solve anything by looking at one line of code, so wowlover6877 can you point out what line in the class that you showed us is line 24? A comment would be nice. Also, could you replace the CODE tags with SYNTAX=java please?

Sigh of course you wrote that as I was writing my post. Still go with the SYNTAX=java tags.

I'm pretty sure you need to get rid of int taskID =.

read my edit.

No, you use that to stop the task if you want. Its no harm, but useless.

Well still, try it. I've never done anything like that before.

I'm still getting same error. I changed the Schedules Task to this:

Code:java

 Bukkit.getServer().getScheduler().scheduleAsyncDelayedTask((Plugin) this, new Runnable() {
 
public void run() {
b.setType(Material.AIR);
 
 
 
}
}, 20L);

 

Change it from (Plugin)this to plugin, and at the top of your class (under public class <name>) make a constructor that says something like:

Code:java

<PluginName> plugin;
public <ClassName>(<PluginName> plugin) {
    this.plugin = plugin;
}

Without the < and >s

EDIT: It gets rid of the errors, but it doesn't work anymore. Theres no more portals spawning

Code:java

package Freedom;
 
import org.bukkit.*;
import org.bukkit.block.Block;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
 
public class VoidCommand implements Listener {
Freedom plugin;
 
public VoidCommand(Freedom plugin) {
this.plugin = plugin;
}
 
@EventHandler
public void PortalPlace(PlayerMoveEvent e) {
Location l = e.getPlayer().getLocation();
World w = l.getWorld();
final Block b = w.getBlockAt(l);
b.setType(Material.PORTAL);
Bukkit.getServer().getScheduler().scheduleAsyncDelayedTask(plugin, new Runnable() {
 
public void run() {
b.setType(Material.AIR);
 
 
 
}
}, 1L);
 
}
}

 

Should work fine. Have you tested it?

 

It gets rid of errors, but doesn't spawn anymore portals.

 

I feel like there may be a packet for this.

 

If this is a dumb question please forgive me: How do you use packets?

 

No clue. Haven't had cause to use them before myself. You can probably find some source code to look at somewhere.

 

Sorry, then I'm not sure. Someone else help out?

 

I am just looking for the same thing, to figure out how to play ender portal effect like in CommandBin is command /drunk. I found something about other packet, which plays the credits scene, here: http://forums.bukkit.org/threads/anyone-familiar-with-packets.89159/. You can use some packets this way, to apply them to players. Now I am just trying to play this effect:

Code:

player.getWorld().playEffect(player.getLocation(), Effect.ENDER_SIGNAL, 0);

I will let you know what does it do.

Ok, I can tell you, that these playEffect visual effects don't seem to do anything. But I found out how the /drunk command in CommandBin works:

Code:

player.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 1200, 1000));

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

 

portal effect is client side, sadly enough. And there are no packets to trigger it (not that I found so far)

 

Maybe you did it wrong?
A power of 1 should do

 

okey wait soon i am coming for this Ans.

 

No there's nothing wrong, the code I posted works.

 

perwin mmmh nice and spacey :3. Never knew this effect existed (I knew the PTE existed, but not that this was the result)
