You're getting a NullPointerException at line 27 of AKSkiller.java

 

If you showed the chunk of code surrounding that line, I could help further. My guess is you're trying to use an API method within the constructor of the class that extends Script.

 

Don't use the constructor. Instead, use the onStart method to write code you want to execute when the script starts. Calling things like myPlayer() in the constructor of your script class would result in a NPE, and seeing how you're getting one in the constructor, I'm guessing that's the reason.

Yeah, initializing in the field is similar to initializing in the constructor.

Assign the values in onStart, not the field.

Okay thanks ! I'll update once I do that!

I'm pretty certain that getWidgets().get(x, y); will actually return a NullPointerException if the widget is not open (citation needed)

Fix:

if (getWidgets().isVisible(x, y)) {
    RS2Widget widget = getWidgets().get(x, y);
}

It will not throw an NPE if the widget is not present. It will simply return null

Right, my apologies.
