NullPointerException: Scoreboard

Hello bukkit, I am having a strange problem. When ever I use; Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard(); It always throws a NullPointerException on startup, and when I reload the server it works fine. I don't know what is wrong on the startup, maybe there is something that should go in the onEnable() method?

Thanks!

 

Taken from the Javadocs

 

lycano ahhh. That explains it. Any idea how to fix if possible?

 

ShadowLAX don't call it before onEnable

 

@mbaxterI do have it called after my onEnable(),

Code:java

public void onEnable() {
getLogger().info("has been enabled!");
Bukkit.getServer().getPluginManager().registerEvents(new Listener(this), this);
}
 
public void onDisable() {
getLogger().info("has been disabled!");
}
 
Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard();
 
//rest of my code

This should work, right?

 

ShadowLAX xD *caugh* visually spoken it is defined after onEnable() but technically its initialized when the class (Your Plugin) gets loaded by the class loader as you defined it as class variable.

So "board" is initalized before onEnable() is even called.

change your code to:

private Scoreboard board;

public void onEnable() {
this.board = Bukkit.getScoreboardManager().getNewScoreboard();
}

and it should work.

Note board is visually placed before onEnable doesnt matter here could also be placed after it (just coding style) what matters is that you do not initalize the Object board before onEnable() which is called by the Bukkit PluginLoader.
