Question

Im creating a game in Flash and I have a class that have some text fields that I need to populate in this case a highScore. I get this error.

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Meaning that the object doesn´t exist , for some reason.

if (highscore.data.hard != null){ 
    highscore_txt.text= String( highscore.data.hard);. 
}

The highscore_txt I have created it , on the design view , meaning timeline.

I have other textfield, that I acess like the score and dont have any problem, this is problable because is acessed and I try to write to the textfield in the constructer of the class. I have done some tests and if I populate the field after all the constructer stuff is done , it works, like when I click some place and call that function using a eventlister.

what can I do , so that only after the class is completed initialized I insert the data in the textfield, is there any event that is listening for the class endes to create itself??

Answer 1

Just put an event Listener in your constructor that listens to the ADDED_TO_STAGE-event 🙂

addEventListener(Event.ADDED_TO_STAGE, yourFunctionToPopulate);

private function yourFunctionToPopulate(e:Event):void
{}
