Edit:

Going to stick with the normal way i code then.

 

your API is silly enough as is, im not changing my whole style for it.

add System.out.println(client.myPlayer());System.out.println(client.getPosition());System.out.println(client.getPosition().getZ());

show output

But yh u can always try script.client.getPlane()

add System.out.println(client.myPlayer());System.out.println(client.getPosition());System.out.println(client.getPosition().getZ());

show output

But yh u can always try script.client.getPlane()

i'll try that

 

EDIT: nope error still

its a null pointer exception so check to see if your player isnt null null checking it plane

You should be using an ArrayList here (while programming to the interface as well):

List<ScriptTask> tasks = new ArrayList<ScriptTask>();

LinkedList orders elements sequentially, so their good when you need to add/remove things. ArrayList on the other hand has faster read access. It's not a big deal here but it's just something I noticed

 

As for your actual question, most likely client is returning null because you don't have an instance of it. Actually, on second look that is 100% the issue because you're extending Script in your class which is giving you another instance of script besides the one that was actually initialized. You need to pass the Script instance from your main class to the separate classes you use.

dont let onGround extend script, make a constructor for the onGround and like swizz said initialize it. Use this as an example.
