Question

I was trying to code the code below into a package that came from a tutorial, but it originally had it in the timeline

now it gives the error 1180: Call to a possibly undefined method Player.

here is a snippet from the concerning code (full code is below that)

private var player:Player;

    public function RamboCat() 
    {

    player = new Player();

So Player is not defined. Does this mean it’s missing a AS file or something
But i’m trying to tell flash to use a image (image is instanced ‘player’)

i added the above code (minus the public function that already existed) because i found
a source which explained i should add those: http://www.actionscript.org/forums/showthread.php3?t=268065

my experience with “package” and “import” things is a bit low. So hopefully you can help.

Answer 1

It cannot be a reference to an instance of player as: new Player(); creates a new instance of Player.

So Player needs to be a class. If you are using Adobe Flash Professional, you can right click the image in the library, click properties, actionscript tab, then export to actionscript (make sure the class is called Player). this will create the class for the image for you.

If you are not using Adobe flash professional, then let me know and I will help with the IDE you are using.

Edit: And looking back you will also need to import Keyboard Class if you have not done already.
