If defining ‘ball’ on the timeline and not in code - be sure to have it on stage and available before any code actually is executed. For instance - have a frame after the frame where ball is defined that you write the code on, invoking it… also - be sure your ‘ball’ object remains on frame when the code executes.

Error #1010 usually means that something is undefined at runtime.

In this case, this.ball is probably undefined when the code runs. Please check that the object on the stage has the instance name "ball", not just the library symbol name.

Also, this code looks like HTML5 Canvas / CreateJS code, but the error message looks like an ActionScript 3.0 error.
Are you using HTML5 Canvas or ActionScript 3.0?
If your document is an ActionScript 3.0 FLA, this.ball.on("pressmove", ...) will not work. You need to use addEventListener with MouseEvent instead.
