Displaying Heart Particles

Hey, I am trying to play heart particle effects to someone on command, I tried using the wolf heart effect but it didn't work, I'm not too good with Packets, but I might think that they're the only option, but I'm not that sure how to use them, all help is appreciated.

PHP:

    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        Player p = (Player) sender;
        if(commandLabel.equalsIgnoreCase("love")) {
            if(args.length == 0) {
               
                for(Player on : Bukkit.getServer().getOnlinePlayers())
                if(args[0].equals(on)) {
                    p.getServer().getPlayer(args[0]);
                    Player arg = p.getServer().getPlayer(args[0]);
                //code  

 

Use something like this or this.

 

Note: args.length starts at 1, not 0, so use args.length == 1, not 0

 

Also, do this for getting a player based on a String argument:

Code:java

Player target = Bukkit.getPlayer(args[0]);
 
if(target != null){
  //Display hearts
} else {
  //No player found
}

 

chasechocolate I added the class but I'm not quite sure how I would use it, I thought I could have done something like player.playEffect(ParticleEffect.HEART);

 

Samthelord1 which class? With the latter, you would use ParticleEffect.HEART.sendToPlayer(...).

 

chasechocolate with ParticleEffects.HEART.sendToPlayer(target); it says i need player, location, float, float, float, float, int

 

Samthelord1 assuming you are using eclipse, hit CTRL + space after "sendToPlayer". It will show you what you need to add as arguments.

 

chasechocolate using netbeans, but it says to use

ParticleEffects.HEART.sendToPlayer(target, null, offsetX, offsetY, offsetZ, speed, count);
which throws error on all besides target

EDIT: should this work? :

PHP:

Player target = Bukkit.getPlayer(args[0]);
                  if(target != null){
                      try {
                          ParticleEffects.HEART.sendToPlayer(target, target.getLocation(), 0, 1, 0, 5, 10);
                      } catch (Exception ex) {
                          Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
                      }

 

Samthelord1 it should as far as I can see. Try it out.

 

chasechocolate ok, I'm all prepped to love myself lol

chasechocolate not working, but when doing /love I get a error on line 33 which is

Player target = Bukkit.getPlayer(args[0]);

should i change it to
Player target = Bukkit.getServer.getPlayer(args[0]);

Samthelord1
Check args length much?

 

xTrollxDudex what?

 

Samthelord1 you need to check the length of the args before accessing an object at an index that couldn't exist:

Code:java

if(args.length == 1){
  //Do stuff
}

 

chasechocolate wouldn't I be checking if args length is 0?

chasechocolate i have

if(commandLabel.equalsIgnoreCase("love")) {
if(args.length == 0) {


Player target = Bukkit.getPlayer(args[0]);
if(target != null){
try {
ParticleEffects.HEART.sendToPlayer(target, target.getLocation(), 0, 1, 0, 5, 10);
} catch (Exception ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);

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

 

Samthelord1 change if(args.length == 0) to if(args.length == 1). Arrays start at 0, not 1.

 

chasechocolate I always thought args started at 0 o.0

chasechocolate this doesn't work, it says an internal error in chat nothing in console.

Samthelord1 args.length returns the size of the array (e.g. 1 object stored = 1, 2 objects stored = 2, etc.). However, if you want to access the first object stored in the array, you would use args[0] as the stored objects start at 0, but the size starts at 1. tl;dr change args[1] to args[0].

 

chasechocolate confused confused xD I think I might understand though.

chasechocolate its working however, it like plays the hearts on the players body and they go up in a line, any idea how I would change it?

Play with the x y z offsets and speed
