Actionscript 3 :: Making Platform Game Method To Stop Running?

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).

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.

Flash :: Data Structure For Side Scrolling Game?

Mar 27, 2011

I was just wondering what the best data structure would be to use to represent data objects in a side scrolling game, basically the stuff the user can't see isn't on the stage so I would generally create a custom class to define its properties (x,y,weight,type, derp, etc) and then push that into an array and as the user moves forward I project the info from the array while checking if their x position is.

The problem that can occur is that the user can move left and right so whats the best way to keep track of the indexes?

ActionScript 3.0 :: Error #1009 In My Platform Game?

Jul 22, 2010

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

ActionScript 3 :: Platform Game - EFrame Continues To Run

Mar 13, 2012

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.

ActionScript 2.0 :: Create 2d Platform Shooting Game?

Feb 13, 2011

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 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.

ActionScript 3.0 :: Platform Game 0 Can't Get Enemies To Face Hero

Nov 24, 2010

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;}

ActionScript 2.0 :: Platform Game - Turning Off Variable In MovieClip

Feb 14, 2011

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);

ActionScript 3.0 :: Platform Game - Disable Jump When Falling?

Nov 17, 2008

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.

Java :: Platform For Web-based Multi-player Game?

Sep 28, 2010

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.
