Question

Okay, so first, I have searched for this everywhere but it seems like every answer is either overcomplicated or simply does not work, and I know for sure there should be a more simple way of achieving what I need.

So, until today, I have always coded from within the timeline. But now I realise why I should code in separate class files. However, I still want to include snippets of code in the timeline for simplicity’s sake.

So in my Ship class I have this line of code:

    public var speed:int = 2 + Math.ceil(Math.random() * 4)

And in my timeline I have the code:

import Ship;
trace(Ship.speed)

I can’t get the trace to display the speed. The class file executes perfectly on its own but when I try to access its speed variable (as above in the timeline), I get this:

Scene 1, Layer ‘Actions’, Frame 1, Line 2 1119: Access of possibly undefined property speed through a reference with static type Class.

So a simple question, and apologies for it, but can anyone give me a simple way to trace the speed from the Ship.as class file?

Thanks in advance!

Answer 1

You need to create a Ship instance, like this:

import Ship;
var ship:Ship = new Ship();
trace(ship.speed);

OR

You can declare speed as a static variable to access it without the need of an instance (but I think here it makes less sense):

public static var speed:int = 2;//or whatever
