SoftDepend

create a conditional to see if the plugin is loaded?

Code (Text):

if(Bukkit.getServer().getPluginManager().getPlugin("VanishNoPacket") != null){

// do stuff

}else{

//other stuff

}

Reference.

 

Reflection instead of importing I guess...

Check and see if it VanishNoPacket is loaded, if it is, cast a method call to it, and then use it as reference.

If it is not, then don't use it .

 

1. Make sure you add VanishNoPacket to your softdepend section in the plugin.yml.
Example: softdepend: [OnePlugin, AnotherPlugin]
This will make sure soft-depended plugin will load before yours.

2. Use Bukkit.getPluginManager.getPlugin("VanishNoPlugin"), if it is null, means it is never loaded.

Well I can't write the whole thing for you.. sorry. But all the information you need to get this done has been given. If you do not understand reflection in Java, then I can help you out:

Here.

Two people have no told you the exact same answer, and you keep saying 'I don't get it'... then learn it .

 

Why so complicated?
Do this: Create a class (call it VNPHook or something else)
Put everything, which needs VNP, into this class and only call the methods in it, if VNP is found...

 

Yeah.. 3rd person to tell him this.

 

So, what I think the people above tried to explain (... but, well, didn't manage to) is that you shouldn't import anything from VanishNoPacket into your main class, but keep it to a separate class (with listeners etc.). If VanishNoPacket is loaded, then you register those listeners - That way you have no imports from VNP in your plugin, unless the plugin is loaded.

Main Class

Code (Java):

...
private VNPHook vnpHook;
@Override
public void onEnable() {
  if (Bukkit.getServer().getPluginManager().getPlugin("VanishNoPacket") != null)
    vnpHook = new VNPHook();
}
...
 

VNPHook

Code (Java):

various imports from vnp;
public class VNPHook() implements Listeners {
  public VNPHook() {
    vnpStuff goes in this class :D;
  }
}
 

 

That's no problem if you only use the vnp stuff if the plugin is available and all vnp stuff is ONLY in that class
