ActionScript 3.0 :: Creating A Vertical Scrolling Space Shooter Game For Deployment On Mobile Platforms Using AIR?
Oct 22, 2011
I am in the process of creating a vertical scrolling space shooter game for deployment on mobile platforms using AIR.I've used some excellent tutorials online, video tutorials on Lynda and several books, including Game Programming University.Something they all seem to gloss over are the various screens that will be used.
For instance, my game right now will use a splash screen, a main menu screen, a credits screen,a settings screen, a difficulties screen, an instruction screen, an end game screen and save/load screen...and a play game screen, where the actual game will be played.I've created the screens as seperate frames in the main timeline with stop commands in between and code on each page (I know... bad!... but easy).So basically,they can navigate through the menus using buttons (mouseclicks, which will work with touchs as well) and when they are How do I pass data between them? I was thinking of storing it in shared object.

I'm a bit of a newbie to this so I decided to follow this URL...The problem is that the dragons don't stop so I tried adding a time limit like this:[code]Frame 6 is my game over screen and the removeMovieClip works for the knight and the arrows but not for the dragons. They still carry on.

I'm trying to work through the Vertical Shooter Game within the tutorials section of this site:[URL]I noticed an code error of if spriteX -= steps; (which should have been += steps)However there are further errors within the tutorial as on page 3 where the man should be able to move and shoot his arrows, mine just shoots his arrows and has stopped moving. I'm using CS5 ActionScript3 to do this tutorial.
//---- variables ----
var steps:Number = 5;
var spriteX:Number = 265;
var spriteY:Number = 265;

What is a good framework to build a multiplayer game in Actionscript? I want to create a multiplayer 2D shooter like Asteroids on the Blackberry Playbook; my main concern is latency - a shooter wouldn't be fun if the bullets are super-jerky and unexpectedly hit people. I'm guessing that a UDP-based framework would be the best.

I've been trying to work on this simple vertical plane shooter. I got as far as creating everything and am now on the step to check if my bullet hits an enemy plane or an enemy bullet hits my plane. Because the enemy planes are created dynamically, I am trying to counter that with assigning then names when created so that the bullet knows what to look for. My approach for this might be somewhat wrong though. As for the enemy bullet hitting my plane, I just tell it to look for the instance of the plane already on the stage. Both result in the same error of undefined(the object can't be found).
Here is the code for both bullet collisions and the code for creating enemies.
ActionScript Code:
public function enemyHit(e:Event):void {
//declare i
var i:int;
//check if the bullet hit any enemy object
for(i = 1; i <= MovieClip(root).amount; i++) {
if(this.hitTestObject(enemy + i)) {
trace("enemy hit");
[Code] .....
The bullets have their own class files and the spawn enemy code is located within the fla file.

I'm trying to make a space shooter type game, and I followed a tutorial on flashkit, and I have all that done, but. How do you do powerups? And how can you make the level end? And how can you make a boss? How do you make a powerbar instead of just "Lives" going down when you get hit. I am also doing a FPS type game related to star fox.

As you may have seen from my previous posts, I am creating a side-scrolling action game in Flash/Actionscript 3.0. Right now I am trying to get enemy objects to face the player's direction. Here is what I mean (dartD1 is an instance of the enemy character object. If its scaleX is 1, it's facing right; if its scaleX is -1, it's facing left):

I have a simple shooting game set up. 25 monsters appear on the screen, one after another, until no monsters are left. If you hit one before it disappears, the score increases. If you don't, the score stays the same.
In the actions frame, I placed an empty dynamic text box named score, and set it equal to 0 (declared in the main actions frame). But, seeing as though the monster actions are coded into the library item itself, do I have to declare score, and the score increase there instead?

I've only played around with a dressup and dating sim - and coding using actionscript (and coding in general, only done a little bit of VB and Python before). I've been following a nice arcade side-scroller tutorial on this site which has three parts, if you want to view and go over them to help. It was designed for Flash 5 and I'm using Flash 8 Pro.[code]Anyway, as I was going through and coding/drawing the whole thing I came across a lot of problems and glitches (and a lot of times when the game coding would crash and I'd have to abort it and remake the entire coding again). I sort of stumbled around blindly, deleting and editing code to get things to work, and I'm up to the point where I'm almost finished with the thing. It's still glitchy though.I was wondering if any Flash coders could help me out?I'm going to be creating a Flash game for my programming class and I would prefer if it wasn't screwy (if I need to remake it with less cutesy graphics). xD;; If you could download the .Fla file and fix the coding problems I have.
Playable SWF game on my deviantart account.FLA downloadable file (@ Mediafire; no viruses, trojans, blahblah attached)The enemies tend to randomly explode before the missile has even hit them.The original enemy movie clip doesn't even want to explode.The score counter won't tick for each kill.The boundary box (?) of the player/enemy seems to be too big. You die before you should - in certain positions the enemy gets close and I guess the boundary boxes hit, which initiates the hitTest. It seems premature though, I'm wondering if I can reduce the boundary box, or have it so the enemy and player collide on the actual graphic, and not the movie clip box? I have no idea if this makes sense, I hope it does.There seems to be a bunch of other small glitches too.

I'm very new to flash,and have been digging through google and this site for information on how to piece together an AS2 shooter game.Its going well enough, but I'm having slowdown issues the longer the games runs, and I was hoping someone here could point me in the right direction.To paste an enemy movie clip on the screen, i'm using this:
Code:
var spawn =_root.attachMovie("monster1","monster1"+_root.getNextHighestDepth(),_root.getNextHighestDepth())[code]........
I need them stored in an array so that the player's shots can test weather or not they've hit any monster on the bullet's enter frame function, then call that monster's movie clip's take damage function. I'm using a for loop to do this:
Code:
for(var i in _root.player.foes){
if (this.hitTest(_root.player.foes[i])){
_root.player.foes[i].takedamage();}
}
I think the problem with the slowdown is that each time I place an enemy on the screen the array gets bigger and bigger. The slowdown only happens while the player is shooting, and I suspect the ever longer for loop with the hit testing is causing it.
I'm already removing the monster's movie clips as they get killed or exit the screen, I guess what I need is a way to reduce the size of the array at the same time, or at least tell the for loop not to do a hit test unless the monster is still alive.

I'm making a top-down shooter game. I have keyboard input that moves the ship around and fires a laser.everything works perfect except that when the ship moves diagonal up left, or diagonal down right, the laser can't fire at the same time. It will work in any other direction, including the other diagonals. Just not those two

is this a common problem among movement in games? or do I just need to fix something?

Im attempting to make an overhead shooter game. Ive got the basic movement down already, and rotation towards mouse. For when he shoots, ive set it to duplicate a bullet movie clip, but i only understand how to set it towards one graphical direction(ex: x +, y -)
The code i know ive gotta fix is
onClipEvent (enterFrame) {
this._x += laserMoveSpeed;
if (this._x>1000) {
this.removeMovieClip();
}
}
The little x + part has to be fixed, but i have no idea what to substitute in order to make it shoot from the front.

'm testing functions to make myself a First Player Shooter game and now I have problem with the fire delay. I want a limit of let's say 1 shot per second. I thought that maybe restricting the clickings counted, so it doesn't register the mouse clicks too close to eachother. Or put some kind of interval at the functions delaying the sound and event function, but that seems too hard.
The game so far:[URL]As u see one get multiple sounds when clicking a lot and it's possible to get several points by clicking the ball a lot.Also, when the ball goes behind the tree it's not supposed to be able to shoot. The Flash File: [URL]It's not the exact same, some junk code trying to make the delay...

I'm trying to make a game that's a top down shooter kind of like Asteroids, but there are no asteroids, just enemy ships. Anyway, I'm trying to make a radar for it. The area for the ships to shoot eachother in is 2400 pixels length and height. The stage is 650 x 500 pixels. The radar works fine for when I'm traveling up and down, but the enemy ships on the radar move in the opposite direction as the enemy ships on the screen when I move left to right. When I move left the enemy ships on the radar also go right, instead of left.[code]this code is called from a move objects function which is an ENTER_FRAME event if that helps any.

Viewing it in either Gecko, Webkit or Presto, an unintentional vertical space occurs after the object, before the second div [URL]. Removing whitespace from between tags, or explicitly setting margin and padding does not help.

Is there a way to control the vertical space between two HTML paragraphs, in an AS3 TextField?
I understand and have successfully applied CSS styles via AS3 and have also utilized the TextFormat class.
I am still unable to control the vertical space between a closing and an opening <p> tag: txt.htmlText = "<p>First paragraph here.</p><p>Second paragraph here.</p>"; The example above renders with the correct font and letter-spacing, but the space between paragraphs is either two-times too tall if txt.condenseWhite = false or it is too condensed if txt.condenseWhite = true.
Since only margin-left and margin-right are available CSS attributes in AS3, and not margin-top or margin-bottom, I am at a loss.

I am using mx:Tree (in Flex 4), and assigned a customised MXTreeItemRenderer for every items. As the TreeItemRenderer contains a list with tileLayout, which means the height of every row is variable. So I have to set the tree's "variableRowHeight to true. When I was testing the tree, everything went well. But when I was using the vertical scroller, I met some problems:
The scroll bar did not move to the position I want. When I was scrolling the content, the scroll bar sometimes scrolled to a unwanted position (e.g. the head of the tree). When there are more rows, the problem is more obvious.When I was scrolling the tree, the images were flicking all the time.
