    So I want to make a plugin that uses the wither/enderman boss health bar but for players. I am using eclipse and the BarAPI file to do this. But when I try and run the plugin, it enables but nothing shows up in the game. I check the server bat window and it just gives a long error saying that the events won't pass through. Please help if you can. Thank you in advanced.
    Code:java
    1. package me.myname.healthbar;
    2.  
    3. import me.confuser.barapi.BarAPI;
    4.  
    5. import org.bukkit.entity.Damageable;
    6. import org.bukkit.entity.EntityType;
    7. import org.bukkit.entity.Player;
    8. import org.bukkit.event.EventHandler;
    9. import org.bukkit.event.Listener;
    10. import org.bukkit.event.player.PlayerJoinEvent;
    11. import org.bukkit.plugin.java.JavaPlugin;
    12.  
    13. public class HealthMain extends JavaPlugin implements Listener{
    14.  
    15.     public void onEnable() {
    16.         getServer().getPluginManager().registerEvents(this, this);
    17.     }
    18.  
    19.     @EventHandler
    20.     public void onPlayerJoinEvent(PlayerJoinEvent event) {
    21.         if(event.getPlayer().equals(EntityType.PLAYER)) { 
    22.             Player p = (Player) event.getPlayer();
    23.             Damageable player = p ;
    24.             BarAPI.setHealth(p, (float) (((player.getHealth() + 1) / player.getMaxHealth())) * 100);
    25.     }
    26.  
    27. }
    28. }

    You don't have BarAPI in your server's plugin directory hence the NoClassDefFoundError.

    Thank you. I'll fix that.

    Okay, so that removed the error. But the ender/wither boss bar aren't appearing in the game as the player health. Do you have any idea what's wrong with the code?

    Because you only set it every time the player joins. You'll have to make it change every time you lose a heart.

    Well I want the health bar to appear by default when players join the server, and the health bar acts as a health bar when they lose and gain health points/hearts.

    Yeah, but you only check it once, and that is when the player joins the server. You need to update the bar whenever the player loses/gains health.

    Okay, thank you. I'll see if that works.

    Nothing is working. Plugin is enabled, but no matter which event I use, nothing appears. This is really getting frustrating. I place the BarAPI jar in the plugins folder to remove one error and it still doesn't work. I change the events from playerLogin to EntityRegainHealthEvent, and it still doesn't work. So I have no clue what to do now.

    Use your same code in a EntityDamageEvent and a EntityRegainHealthEvent. You can keep the PlayerJoinEvent in there too

    Yeah, everyone got to start somewhere :)

    Forgot @Eventhandler over the DamageEvent, by the way.

    Also, of my own experience, using "==" is better than ".equals".

    Why don't you just make a method which sets the bar to the health the player has every tick?
    Code:java
    1. public void healthBar(Player p) {
    2. Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask("Your Mainclass", new Runnable() {
    3.   public void run() {
    4.     //set your bar
    5.   }
    6. }, 0L, 20L);
    7. }

    This might cause lag, i would not recommend doing this.

    Samstrongman
    As i said above, this might cause lag, but you would do it like this:

    Code:java
    1. public void healthBar(Player player) {
    2. Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask("Your Mainclass", new Runnable() {
    3. public void run() {
    4. BarAPI.setHealth(p, (float) (((player.getHealth() + 1) / player.getMaxHealth())) * 100);
    5. }
    6. }, 0L, 20L);
    7. }


    Edit:

    and then call the function method.

    Really man, I have a lot of tasks like this running EVERY tick on my localhost with only 4GB ram and it's not lagging! :)
    If every RepeatingTask would lag, why would they have been added then? :D

    I'm so lost... once this plugin gets solved and finished, I'm gonna be so happy.
    Anyways,
    scheduleSyncRepeatingTask is always underlined in red and when I change it to scheduleASyncRepeatingTask, it gets crossed out and suggests it to change back to scheduleSyncRepeatingTask...
    Plus, the player line in player.getHealth and etc are always underlined with no fix I can think of or see.

    So lost. I feel so bad having you guys constantly try and help me. It's cool if you guys want to stop.

    The thing is, doesn't BarAPI show the bar for all the players on the server? Or all the player nearby?
    I used it once and that was the issue with me.

    It depends how you have it setup. I want it so it shows up for all players but it'll have their health status on it individually.

    Okay I rewrote some parts of the code, but it still doesn't work. Does anyone see an error in the code I wrote? I would like to get this plugin functional as soon as possible.

    Just a tip, I would make sure the mob is an enderdragon and not a wither, as wither boss bar's are kind of weird having a short radius and all, whereas with an enderdragon the radius is pretty good, reaching a few hundred blocks. Also, an enderdragon's max health is 200.0, and a player has a max health of 20; so you'd just have to use the right events, take the player's health multiply by ten, and then set it to the boss bar.

    The BarAPI interface is a enderdragon bar. I'm trying to manipulate it to become a player's health bar but the bar won't show up no matter what I do.

    I could send you the class I use for a dragon bar if you'd like.

    Here it is:
    http://pastebin.com/jt6dw5Jb
    WARNING: The location parameter is the location of the enderdragon, I'd put it like at a negative y or something.

    Here is an example of how to use it:
    Code:java
    1. DragonBar.displayDragonBar(*Bar's Name*, *A player*, *A location*, *Health of the Dragon*);
