Comments on: AS3 Flash Games for Beginners: Using Frame Labels and Art Tweening

Just wanted to point out that you need to remove the enemies from the collision list once you hit them (and yes, I did check this time)

As it plays right now, it is possible to hit a foe infinite times because even while they are exploding you can still hit them and trigger the explosion sequence again and again endlessly.

first, thanks a lot for the tutos… they are really good!

im using flash cs5

when i try to create the motion tween of the explotion of the stinger flash sais that could not create the motion tween cuz the object has action script associate or other elements that dont accept the motion tween….

so i will do the explotion of the stinger frame to frame like i did the laser hit implosion…

I think, we can fix the error like said mike:

Meet and Sepiantum : I had the same error, then realized it must be saying Null because the hitbox goes away. I figured this out because I noticed that the error only happens after you shoot the ship as it’s being destroyed. To get rid of the error, you have to make sure teh hitbox keyframes extend to the end of the animation. However, this introduces the bug as said above where you can keep destroying the same ship over and over – it replays the destroyed animation. I haven’t read the last tutorial yet so I dunno how to fix it but I’m off to read it now!

Thanks for the tuts!

and to fix the bug we can create a new keyframe in frame 2 and reduce “hit” instance to 1 “pixel”…
It’s why i dont know much in programing.

Hi, I found a little bug… when BlueLaser hit a enemy multiple times, while destroying animation is running, then the animation run again and again like you hit many enemies

Great article, thanks
currently, i’m doing some studying experimenting with Flex/Flash, looking for ways of organizing a formidable designer/developer workflow…
One thing that caught my attention is “MovieClip::currentLabel”:
it seems that when you have multiple layers with “intersecting” frame labels in them, when the clip gets animated – the last framelabel caught during playback, will be the one set as the “MovieClip::currentLabel”.

In other words, it should be stressed that clauses such as:
if (currentLabel != “destroyed”)
may be used only in MovieClips that have only a single layer defining frame labels.

EvulNater,

Thanks for that heads up on how to solve the Error #2007. That was driving me nuts. It didn’t seem to be effecting anything, but it’s still a pain. Thanks

BugSlayer, SAMM_47, and mike, you all have probably moved onto other projects by now, but I figured an easy solution for the “shoot enemy again while they explode” problem. To the Stinger class, add “public var alive:Boolean = true;” with the other variables, and under the if statement of the takeHit() function, add “alive = false”. Then, over in the LaserBlue class, change the if statement in loop() to look like this “if (hitTestObject(Engine.enemyList[i].hit) && Engine.enemyList[i].alive)”.

Thanks so much for the tutorial. Its like taking an entire Flash class in one go!
I just have one question. I’m trying to make it so that the Stinger ships “yell” something when they die, which I made with a dynamic text field positioned behind the ship, with the instance name of “yells”. I imported flash.text.TextField, and created a private var lastwords:Array = new Array(); in my Stinger class, and set the first 0-4 positions with words or phrases set as strings, ie lastwords[0] = “Damn!”; in my constructor. I am working with this line, yells.text = lastwords[(Math.floor(Math.random() * 5)]. However, no matter where I put it, I get: TypeError: Error #1009: Cannot access a property or method of a null object reference. Any ideas?

would it be possible to show a version of this tutorial with you being able to die? maybe even give us hit points or lives.
