NullReferenceException and classes
Okay, I thought I understood all this, but now suddenly I'm at a loss. This NullReferenceException error (Object Reference not set to an instance of an object) gives me little information about what I'm doing wrong.
Basically, I have a class called "trigger", set up as just a bunch of variables like so:
class trigger {
var name:String = "Idle";
}
Then in another script, I attempt to make an array of these triggers, like so:
public var myCode:trigger[];
public function makeTrigger(howMany:Number){
myCode = new trigger[howMany];
Debug.Log("thisTrigger: "+myCode[0].name);
}
It's that Debug.Log line that pops the error. Obviously, anything more I try to do with my trigger class doesn't work. If I debug the length of myCode, I get the right number, but somehow the class is empty. I don't understand.
Any help would be just awesome. Thanks in advance, Jeremy
You've created an array of trigger references, but you still haven't created the triggers themselves. You need something like ...
public var myCode:trigger[];
public function makeTrigger(howMany:Number){
myCode = new trigger[howMany];
for (var i = 0; i < howMany; ++i){
trigger[i] = new trigger();
}
Debug.Log("thisTrigger: "+myCode[0].name);
}
(Apologies if my C# is showing, but you get the idea ...)
Ahhhh... thank you. I thought the myCode=new trigger[how$$anonymous$$any] did that automatically. Well, thank you so much. You just saved me hours of frustration.
