how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides.

I am creating a 2d platform shooting game. Currently I have my main character walking around left and right and the stage background also moves left and right.
The problem I am having is that if I go to far left the charater just walks 'off stage' and into nothingness but the stage still follows. How can I make it so if the character hits a certain point he just 'stops' and cant go left no more but can go right no problem. I have tried using hitTest with another movieclip but couldnt get it working.[code]...

I am going to develop a very simple game for android and for iphone/ipad I have the option to develop it in cocos2d or in adobe flash air (i am not a developer, but i have 2 developers who are offering me the service)I have a developer that states that cocos2d is better and other one that states that adobe flash air.I want it in cross platform.the cost offered by both developers is the same..i have heard that adobe air has the flaw that it is very slow, is this real? if you had the 2 options which will you use to develop your game and why?

I'm doing a kind of plataform map, and now I need to make health (3 hearts, like Mario). I tried to do it with hittest but the hearts goes like crazy. Guess I need to make something like invulnerable or I don't know. What I want to do is three hearts, and, if the human touches a spike he loses a hearth.

In my basic platform game I have a "hero" that can walk and jump on the "ground." There is also a door to the next scene, which is the next level.The first scene works fine, but "TypeError: Error #1006: value is not a function. at Charles3_fla::MainTimeline/frame1()" pops up once in the output. It works however, and I'm not worried about it. The second I go throught the door though, Scene 2 opens, but then starts flashing as "TypeError: Error #1009: Cannot access a property or method of a null object reference. at Charles3_fla::MainTimeline/onenter()" pops up A LOT in the output. I don't know how to fix it, and would like help. P.S. I am using Adobe CS5 with actionscript 3

I am making a platform game in flash. I have a goal class (the class which contains code for the goal sprite, where when you hit it, it continues to next part of game). Inside the goal constructor, 2 event listeners are added, they are as follows:
addEventListener(Event.ADDED, beginClass);
addEventListener(Event.ENTER_FRAME, eFrame);
The beginClass function is fine, and only runs once, but eFrame is what checks if the player has hit the goal, so it is constantly running. The problem is, once the player hits the goal, eFrame continues to run, while in a menu describing the next scene to the player. My eFrame function is below.
private function eFrame(event:Event):void{
if(hitTestObject(_root.mcMain)){
var lastScore:int = _root.mainScore;
_root.mainScore = lastScore;
while (_root.lvlHolder.numChildren > 0) {
[Code] .....
Frames 2, 3, 4, are frames with just text and a button that display a message to the player, and then the player hits continue. My problem is that eFrame is still trying to be run, but the class has not been instantiated, and the method is causing extreme amounts of lag once the player continues.

I am creating a platform game and am getting the following error:#1009: Cannot access a property or method of a null object referenceThis error happens when I remove all children from the stage on line 154 of the Robbery.as class. Im guessing that maybe it is still listening for event in the other classes but I'm unsure how to remove these from within the document class.

I have gotten to a point with my platform game where I am completely stuck. I have the player movement working fine but the only thing is, it doesn't fall off the blocks.
I have a Floor class which references the Character class and tells it to stop jumping when it is on a block through a hitTestObject. I have tried to research how other games have added functions but can't seem to find one which will work in mine.

I'm making a platform game. The hero can move around, but the enemies are stationary. My problem is that I want the enemies to face the hero. The first enemy behaves correctly, but the subsequent enemies only behave correctly if I kill all the preceding enemies. I have added the hero and the enemies as Objects and put the enemies into an array called enemies. Both the hero and enemy objects have a direction property and an mc property that refers to their movie clips. This for loop gets called every frame.
for(var i:int = 0; i < enemies.length; i++)
{//face hero
if(hero.mc.x < enemies[i].mc.x) enemies[i].direction = -1;
else if(hero.mc.x > enemies[i].mc.x) enemies[i].direction = 1;
enemies[i].mc.scaleX = enemies[i].direction;}

I am working on a platform game and I am having a problem with the script. I have a mc with my character in it named "mcMain", I placed all the script into it. Inside the movie clip I have 20 frames, the first 5 are standing, walking, jumping, crouching, and crawling. Frames 6-20 are an attacking animation. The problem is in frame 20 I want him to go back to frame one and turn off a variable (called "ram") in the movie clip.
The problem is with the variable ram (which is established in the onClipEvent(load) section of the script). I have it turn on when the character attacks and I want it to turn off after the animation is complete. The problem is it is not turning off. I have it targeted but it does nothing. I have tired both a direct and relevant target along with a _parent.ram = false;
Here is the script on the movie clip.
Actionscript Code:
//Establish VariablesonClipEvent (load) {
var speed:Number = 0;var walk:Number = 6;
var run:Number = 12;var grav:Number = 0;
var falling:Number = 0;
var jumped:Boolean = false;var jumpHeight:Number = 23;
[Code] .....
And here is the script inside the movie clip on frame 20
Actionscript Code:
_root.mcMain.ram = false;gotoAndStop(1);

I'm making a platform game in AS3. I've sorted the left,right and jumping movement of my character - apart from one jumpingproblem:When the up arrow key is down it sets the jump var to true.ENTER_FRAME function detects when jump = true and it decreases thecharacters y position by the var velocity while at the same timedecreasing velocity by 1.5px. So my character jumps up to a certainheight then comes down - There is a hit test to stop heump/fall. BUT when the character falls off a platform he can still jumpwhen the up arrow is pressed. I've been racking my brains but I canstop the character from jumping if its falling.

I'm developing a web-based fantasy football game. Most of the game is a straight-forward web application built on top of Linux/Apache/Php/MySQL.
I'm trying to figure out how to implement the draft application. The draft date and time will be scheduled in advance by each league's owner. Up to 32 users may be logged on for a given league's draft, and there is no limit to how many drafts may be happening concurrently. The users will take turns selecting players, and each user's turn will have a time limit. I'd like for all the users to be able to see whose turn it is, how much time that user has left to select a player, who they select, and which players are still available. If there are users in the league who are not logged in during the draft I'd like to be able to detect that and automatically assign players to them rather than waiting for the time to run out on their turn. Ideally I'd also like to have a chat window so the users could chat with one another during the draft.
My background is in desktop application development, so if necessary I could write server code in C#/.NET or Java. As far as I can see these are the options: PHP/AJAX - It seems like it would be possible to have all the state for the draft in the database and have the operations for the draft run in PHP triggered by requests from the clients? I guess in this case the draft doesn't start until at least one user logs in, and it seems like it would be a lot of polling requests to the server if I want everyone notified quickly when a user makes a selection.

I'm just starting out in actionscript 3.0, and I'm trying to create a basic platform game. Since I don't really have time to code it from A to Z, I'm using an 'engine' I found here. I've made a few modifications (mostly deleting stuff I don't need, such as the enemies and the coins). Now I'd like to create a crate that the player character can pick-up, throw, put down and jump on. I've created a new class (Cage.as) for it, based on the player class. When I run the game, the crate is displayed, but it just floats there. I can't figure how to make it interact with gravity (i.e. fall to the ground).

we just recently defended our graduation project which is a platform game like mario. one of the modifications suggested by our panelists is to make level 1 generate random places for enemies and coins after one of them said that mario was a stupid game because you already know where the enemies are, the powerups, etc. i said i'll give it a go and see what i can do. but recently i realized that i havent played any platform game that generates random places for the enemies, coins and other objects. it is only in rpg games like ragnarok that i have seen enemies spawning at random places.

We're looking for a good server to purchase to develop games with Flash/Android/iPhone clients with a .NET backend server (And even more importantly, that supports clustering and scaling in general).Now we've examined both ElectroServer and SmartFoxServer (both products look fine and suitable for our needs), however both can only be extended using Java.

I am a beginner to flash gaming. I am making a platform game, but can not reverse my character when he goes backwards. This is my code for left and right: if (Key.isDown(Key.RIGHT)) {_x += speed;} if (Key.isDown(Key.LEFT)) {_x -= speed;} How Can I reverse it so when it goes LEFT, the character turns all the way around?

I want to make an interactive image scroller. I am making a webshop and I want a flash to scroll through some of the latest products (3 or 4) that I put in myself and animate or whatever, maybe there's a better and easier way. I want this movie to have these products scrolling from right to left by auto with maybe an ease effect, but when you move your mouse pointer over the whole movie I want it to stop, and when it stops I want two arrows appear on the left and right side of the movie which will be clickable and you will be able to scroll through the products with them as well.
It doesn't need to have an external XML connection where you insert scrolling speed and so on. Of course it would be simplier, but without is fine too. I will try to explain in what terms I know of:
-Mouseout/rollout = 3 or 4 products scrolling one by one from the right and ease in to the middle, pause 4 seconds, then scroll out to the left with an ease. Looped.
-Mouseover/rollover = Movie stops and then you can use arrows on both each side and scroll by yourself. But I don't know if I want this only to be available when the product is in the center of the movie, or else it would be kind of weird if the movie stopped when one product was just about to go half-way out or in.
