ActionScript 3 :: Flash Game Inventory - Design Pattern
Aug 23, 2011
I'm still studying OOP designs, so what's the best way to achieve an inventory for a simple flash game? It seems that more than one design pattern could deliver some kind of an inventory but I would lose the flexibility if I try to adapt it somehow without a good knowledge about the subject. For money to buy what is available in an inventory I thought of Singleton. If there's enough cash earned while playing the game, then one can buy new skills. Maybe decorator pattern could list many thumbnails as buttons, and clicking on it applies new features and skills to the character.

I'm looking to get some good books on design patterns and I'm wondering what particular pattern you'd recommend for a Realtime Strategy Game (like Starcraft), MVC?. I'd like to make a basic RTS in Flash at some point and I want to start studying the best pattern for this.

I haven't found the best process is integrating SWFAddress. I've used it on just about every project since it came out, but I rarely have something reusable, and integrating SWFAddress is one of the more time/thought intensive tasks in the dev of a project.

I'm just beginning to wrap my head around design patterns. I'm in the process of rebuilding a slideshow using MVC and it's coming along nicely. I'm considering using a design pattern for the whole site and am wondering if there are certain patterns that people usually apply to sites.

I have an application that takes the user through a set of steps, configuring a product, say about 10+ screens. With options to go back, skip to a certain point etc. I need to fade between these steps, and also have language switches available at any point.
I was thinking of using an MVC style pattern, having a master view that accepts a 'next view' and fades it in, removing the old.
It feels bloated to have 10+ separate view classes, using similar components for this task, so was wondering what other approaches there are that I should look into? or one that is suited for this kind of application

I am not able to understand, why a static class cannot replace a Singleton design pattern .
Cannot a static class, can be used to ensure, the class is never/once only, instantiated. Because that is the facility "static" key words provide , however it doesnot allow instantiation, but that is much similar to the limitation of instantiation once only.

There are many times that I've needed to execute some code after a number of events have fired, and I've come up with counters and such but I feel there must be a better way.For example, say five files need to be loaded, after which a UI component will become active.If I set up a counter that increments each time a file is requested, then decrements each time one has loaded, I run the risk that the first two or three files may somehow get completely loaded before my code gets around to requesting the fourth and fifth, which would mean that my counter would be at zero when I still have two files to load, thus allowing the UI component to be prematurely activated.
There are some cases where you could know the number that need to be loaded before the requests go out, but it's possible that the first file contains the paths (and therefore the number of) files.And this file-loading scenario is only an example of the pattern I'm trying to explain.)

Would like to know what is the best way of designing and building a basic AS2 flash dress-up game for girls and boys.
Are there any templates one can get going with?
The flash should be able to save a snapshot at any given moment and email the snapshot to 5 or less friends.

ame_Manager.as= this manages the creation of balloons, players and collisionsBalloon.as= This is the balloon classPlayer.as=This is the player classThe Game Manager class will pass stage to the balloon and player classes and create them. I add these two in the Game Manager class.In the balloon class i add all the balloons in an balloon array.Now when i run the code i am unable to check for collisions as nothing happens when the player and balloon collides. and i get a child must be a caller of the display object when i ry to remove the balloons after they have crossed the stage.I have been trying to make it work for a long time a the game is very very simple.in the Object Oriented way of designing this simple game as i think that is where my error might be.I will post the code for these belowGame Manager.as
Code:
public class GameManager extends MovieClip{

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]............

This may seem like a noobish question (and it is) but I have created some AS code to help assist in a project of mine in a level design class to create a mock interface for a game. It works fine on the first screen but once you hit any button and go to the next and then try to go back, the code breaks and I am not sure why. Ive tried multiple things to get it to work but nothing seems to help. The code I am using is
ActionScript Code:
storybtn.addEventListener(MouseEvent.CLICK, start1);
function start1(MouseEvent){
gotoAndPlay(2);

I want to create a 2D real time multiplayer game in the browser in Action Script that can do the following:
Client: Player logs into Account via Flash Client. Player hits 'Versus Mode' Button. A lobby with a list of online servers come up. Player joins game. Heres where the problem comes in, I want the servers to be community hosted. i.e. the player downloads and runs a server app on their own desktop for other players to join. Players then go to the website and access the browser based client to find a list of active servers.
This would be a commercial product (players buy an account to log in through the client) and each player hosted server must handle 20 live players. As the servers are not centralized and scalability is handled by the community typical solutions like SmartFoxServer licences will not work.

i'm trying to search a string for a particular pattern, and replace it with elements from within the pattern... for example..here's the given string...if you want to learn how to use regexp, {url===http://somesite.com, text===click here}.
the pattern...
{url===http://somesite.com, text===replacement text}
and the intended result...
if you want to learn how to use regexp, click here.
of course, i'll extract the url and do something else with it... i'm just wondering what the regexp is for that pattern, and how i can extract things from the results returned.

I'm making a sort of interactive graphic novel and was wondering how would I implement some sort of inventory system. Btw, I'm using Actionscript 2.0
----INVENTORY SYSTEM 001----
You see, I would like the ending screen to show a summary of what the player has done in the game.And certain points in the game would add certain 'items' into the inventory which will in turn affect what is displayed in the summary screen.The 'items' here being words or phrases.eg:
Quote:
You _______ with the _______ and proceeded to _______. But you _______.
For example, if the player chooses Path A, summary screen will show: eg:
Quote: You stabbed the unicorn with the shark fin and proceeded to shag your mistress. But you ate a pecan pie.But if the player chooses Path B, the summary screen will instead show eg:
Quote: You stabbed the tree with the shark fin and proceeded to shag the corned beef. But you smashed a watermelon and caused a civil war.
----INVENTORY SYSTEM 002----
I think with a few modifications, this inventory system could also be used to affect the outcome of the movie depending on what item the player currently owns? Please enlighten me if this system is feasible.
The player is given a choice to pick up a spoon or a fork in the beginning of the game.The player is later faced with a soup crisis. If the player has previously picked up a spoon, the soup can be consumed. Otherwise, the soup is left well alone.

So you start off with all of the items in the inventory. You do not have to collect them.I have 8 MovieClips on the stage each with a different instance name. I made a class called Rebound and linked all the inventory MoivieClips to the Rebound class as the base class. they each have their own unique class.What I'm trying to do is select one of them. when you release the mouse off the movie clip (MOUSE_UP)it goes to frame 2 of its movieclip and making a variable I made up called isSelected = true.but when you click another item in the inventory I want it to deselect the item you clicked first so it goes back to frame 1 and isSelected = false. The problem I'm having is that it selects the first item when you click it. But when I click another the first stays on frame 1 and isSelected stays true. So if I click all 8 in a row they all become selected.[code]I thought this. called on every movieclip of the Rebound class?So instead of this. if there is something that can choose all of the movieclips that belong to the Rebound class I think I could use that instead. If there is such thing.

I know this might sound odd, but if I wanted to create an app using Flash for my iPad, but just for me,not for distribution, do I still have to have an Apple Developer license?
I just want to create an in-house app for pricing and inventory. It's a unique business, so selling it isn't even an issue, but I don't want to have to spend another $99 just to try it out and see if this would be something we'd use long-term.So, can I make an iPad app just for myself without anything extra?

I'm trying to implement an inventory functionality into my program, i.e. equipping and taking items off a player character. I have created a superclass named 'Item' which I would like another two classes to inherit from. Those would be 'Weapon' and 'Armor' classes. The superclass 'Item' contains at this moment a list of variables that can describe any item, e.g. name, slot, armor, damage, durability. No methods have yet been added. My question is: if my superclass holds all the properties of an item, how exactly would those properties be inhertied by the other two classes? Is it even a good idea? My initial thought was to create a motherclass to hold all the variables and later methods, you could name it a 'variable pool', wherefrom each one could be used by other classes, but it makes me wonder if's going to be of any use. If you don't mind, would you create for me two short code snippets to show me how a superclass can cooperate with its subclasses?
