I also wonder what happened to our AS3 “teacher”. I really enjoyed his/her teaching. I hope he/she will return one day and continue the teaching. I would like to learn how you handle sprite collisions, scoring, removing objects when hit by other objects, scrolling of backgrounds, taking/porting the game to IOS and Android etc, etc.

A tip for those of you that follows the tutorial to the teeth but got no response when clicking the “enemy” object, remember to look in your toolbar at the top of your development tool for the dropdown saying “Release”. It should be next to the blue triangle. That dropdown value should be “Debug”. You will only see the “trace” messages displaying in your “Output” window when that setting is “Debug” just before you “Build” or “Test/Run” your project.

When you sometimes download the project files and overwrites your project with his/her project files you will find that setting is set to “Release” and you need to set it back to “Debug”.

Happy Flashing.

help??

package
{
import enemies.Enemy;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;

public class Main extends Sprite
{
public var enemy:Enemy;
public var player:Player;

public function Main():void
{
addEventListener(Event.ENTER_FRAME, handleEnterFrame);
addEventListener(MouseEvent.CLICK, handleClick);

player = new Player();
addChild(player)

enemy = new Enemy();
addChild(enemy)
enemy.x = 500;
enemy.y = 400;

for (var i:int = 0; i < 5; i++)
{
var tmpEnemy:Enemy = new Enemy();
tmpEnemy.x = Math.random() * 800;
tmpEnemy.y = Math.random() * 600;
addChild(tmpEnemy);
}

}

private function handleEnterFrame(e:Event):void
{
player.x += 1;
player.x = mouseX;
player.y = mouseY;
}

private function handleClick(e:MouseEvent):void
{
trace("clicked in main");
var targetEnemy:Enemy = e.target as Enemy;

if (targetEnemy)
{
targetEnemy.y += 20;
}

}

}

}

Hope this helps!!!

addEventListener(MouseEvent.CLICK, handleClick);

In your Main() section. That is what tells the Main() function to pay attention to mouse clicks and call handleClick() whenever it notices one.

Thanks again for the tutorials -lol definitely doesn’t hold your hand but definitely very informative, ta!

I didn’t really understand the piece on e:target, I think you wanted me to make another eventlistener of some kind but I couldn’t find target in any of the drop down options when I used Event or MouseEvent. Maybe it requires a different event to be used to access it?

Also, I’m not sure why we made a player class, it just seems to be there to act as another trace statement.

Either way, I’m sure I’ll figure it out the e:target thing on my own, thanks for providing the initial steps into programming for me.

I am having issues with Error: Access of undefined property e.

private function handleClick(e:MouseEvent):void {
trace(“clicked in main”);
}

and the loop:

for (var i:int = 0; i < 5; i++) {
var tmpEnemy:Enemy = new Enemy();
tmpEnemy.x = Math.random() * 800;
tmpEnemy.y = Math.random() * 600;
addChild(tmpEnemy);
}

Thanks for the tutorial! I am having a little trouble with adding another listener in the main class. I get an error Duplicate function definition. Could you post the final code?

What could be the problem?

Thanks 😮

I spent two hours trying to work out an apparently nonsensical “Access of undefined property x in package player” error message. I finally randomly guessed the problem: I had saved the Player class in a folder called “Player”, instead of in the root folder. All the code referred to the Player folder correctly, but the word must be reserved for something else in Actionscript, because when I renamed the folder it worked perfectly.

Ok, now that I’ve proved my credentials as a total n00b, I’ll give you a little feedback on what it’s like for a novice to read these tutorials. The information is great, it’s broken down well step-by-step, and it’s explained clearly for the most part, but towards the middle you stop explaining where to put things: a lot of passages say “now add this code” without any hint as to where to write it. I muddled through mostly by trial and error.

But I got there in the end! It feels like a victory, but it’s daunting to think how much there is still to learn. 😡

Thanks for taking the time to write out this very helpful tutorial. You’ve earned good internet karma!
