ActionScript 3.0 :: Tower Defense Type Game - Object Access?

Feb 14, 2012

I am hammering out a Tower Defense type game. I'm starting to design my custom unit mechanics. I've used numerous other tutorials for the framework here (largely one mans blog - credited in my AS3 file..) I want when a unit dies, that it runs a function - checks a field I've created within the unit called a 'tag' - and depending on that do other things. From within the kill() function I successfully call my infantryDeath() function, and I've verified within kill() it's recognizing the dead objects tag. I've verified the entry into infantryDeath() and that the tag is still the same.

Here's the problem:
function infantryDeath(creep){
//inGameMessage("infantryDeath() successfully called"); <-- works
//inGameMessage("Unit died with ID: " + creep.tag); <-- properly shows the ID of the "creep" it received
inGameMessage(this); <-- prints out _level0 (the id for the level itself)
if (creep.tag = c1) <-- the unit with this tag dies, and triggers this block successfully{
[Code] .....

I have no clue why the object I'm supposedly working with changes just by virtue of being within the "if" block. If I pass an object into a function shouldn't manipulating that object remain constant within that function?

Tower Defense Game Bullet Disappear

Mar 16, 2010

I found a tutorial on the internet and have begun toying with it. I figured out what all the segments did and how they worked and effected the game (mostly through trial and error...) once i figured out what EXACTLY i had i started making changes.

-What i want - once the bullet hits a monster OR goes out side of the range of the gun it disappears and another shot can be fired (which is done automatically via my script no user input needed)

-What i have - when the bullet goes off the page (x>550, x<0, Y>400, Y<0) it disappears and another shot can be fired... obviously this is problematic to game play...

Flash :: Tower Defense - Detecting If The Bullet Hits The Enemies

Apr 22, 2011

I am creating a tower defense game and I want to make a tower that shoots a bullet and every enemy that the bullet hits is damaged. The bullet can hurt multiple units. My problem is detecting if the bullet hits the enemies. Right now, I have the enemies in an array. With other towers, when an enemy is in range, the tower fires and when it hits its original target, it causes damage to that target.

For the tower I want to make, it will shoot the bullet the maximum range every time and I need it to damage every unit it hits on the way to that final destination.

ActionScript 3.0 :: Create A Tamagotchi Game Type Game?

Mar 28, 2012

im trying to create a tamagotchi game type game. For some reason i can not add any items to the stage.Currently i have imported 2 png images to the stage and coverted them to movie clips. One is called TamagotchiCharacter and the other is called Beer. I have also created a new 2 AS3.0 script class called TamagotchiGame and DraggableItem. The following is TamagotchiGame:

Code:
package {
import flash.display.MovieClip;
public class TamagotchiGame extends MovieClip {

I have assigned the above code as the BaseClass of the Beer symbol, this has allowed the beer to become draggable and droppable etc.when i run the program nothing happens, i just get a blank white screen.

ActionScript 3.0 :: Create An Inventory For An Adventure Game - Getting Error #1009: Cannot Access A Property Or Method Of A Null Object Reference?

Jan 17, 2010

Im trying to create an inventory for an adventure game (escape the room esque interface).Basically I have an array inventory system - you click on an object that is listed in the array,it moves the item off the main screen and into your inventory (bottom of the screen) and resizes it. Then you can use the object as an inventory object.This is fine on frame one (where all the items are at the moment).But when you move to another frame and then come back to frame one the items are back on the screen in their original position but now non clickable(aswell as being in your inventory working how they should). If i put the items in frame two and no items in frame one I get the following message and the items become unclickable:

Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Inventory/makeInventoryItems()
at InventoryOne

Im guessing the errors are because the items don't exist on all frames but the code does as it is in the games properties as the class type (class Inventory), but i have no idea how to get around it.

Inventory/makeInventoryItems() is the following AS code.

Code:

function makeInventoryItems(arrayOfItems:Array) {
for(var i:int=0;i<arrayOfItems.length;i++) {
arrayOfItems[i].addEventListener(MouseEvent.CLICK, getItem);[code]............

ActionScript 2.0 :: Type Error #1009 "Cannot Access A Property Or Method Of A Null Object Reference"

Feb 6, 2010

I'm using CS4 and AS3 I am getting no compile errors in my code, but in the output window, I keep receiving the following: TypeError: Error #1009: Cannot access a property or method of a null object reference. This prompt appears before I click on the button that is supposed to run the movie clip, so it appears that it is not the problem. I am working with buttons and movie clips; all of my objects are display objects or display containers, so I have no idea what the reference to a null object is. I have not created any custom classes for this, and don't think I would have to for such a simple project.

Stopwatch Type Timer For Game?

Jul 8, 2009

I've got game for kids where you click the right coloured circle.Its not really a game as I'm writing my dissertation on designing interfaces for kids. You didn't ned to know that. Basically, I've made a game where you click the right coloured circle to go to the next level, and what I need is a timer that starts when you click "play" and ends when the last circle is clicked. This is so they can see how long it has taken them.

I have uploaded the fla file here http:[url]....f you could take a look, it's not a big file.I have searched for a while and Ive managed to make counters but only ones that start when the movie loads and I don't know how to stop them.

Php :: Architecture For A Farmville/yoville/cafe World Type Game?

Jan 18, 2010

I'm thinking of building a game along the lines of Farmville - items, events, time management system etc. Options I am thinking of:

1) Flash UI frontend that uses AMFPHP to get all data for the view from a PHP powered backend.

2) Actionscript to power the whole game

My concern with Actionscript is scaling, my concern with PHP is having to build an update system that would need a lot of back and forth xmlhttprequests which might get complicated.

Flex :: Flash Computational Engine For A Connect-4 Type Game Be Too Slow?

Mar 20, 2010

I was just fooling around in my spare time and have made this cool interface and game-playing code for a Connect-4 type game, written in Flex and playable by 2 human players in Flash. It accurately detects wins, etc. I'm smart enough to know that I've done the easy part.Before I dig into an AI for game play, I wanted to ask if this is the kind of thing that can really be handled computationally by a Flash plugin. It seems to me that for every turn up until the end there are 8 possible moves, 8 responses to each move, etc. So wouldn't a perfect engine have to be able to potentially see 8^8 moves (over 16 million), and a fairly good engine see up to a million? I don't know game coding so this is new to me. What's a reasonable move horizon for such a game to be able to see?

Here is all of the code for the game, because I figure I might as well give you everything now, than later. I also wanted to give you all my variable names that would be used...

Code:

Actionscript 3 :: Graphic Object BitMapData Type The Same As BitmapData Type?

Dec 29, 2009

The title might be a little misleading. Look at my code and I will explain

public static function loadTile(tileDir:String = "empty"):void
{
if(tileDir != "empty")
{
tPoint = new Point(0,0);
tRect = new Rectangle(0,0,30,30);

[Code]...

I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.

So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

Actionscript 3 :: Bubble Pop Game / Defining ToString Method Through Reference With A Static Type Class

I have the actionscript code here for a bubble popping game. When the game starts, bubbles fall down from the top of the game to the bottom and score is kept for the most bubbles clicked or popped in 30 seconds.The size of the bubble is defined by the initialize method in the code, and uses ToString() to calculate the score. ToString gives me a 1061: Call to a possibly undefined method Random through a reference with static type uint. This error which I cannot figure out where it comes from.[code]
