ActionScript 3.0 :: Simple Space Ship Game - Motion Synchronization
Oct 12, 2010
I was trying to make a game with simple spaceships and a bullet that is supposed to hit them and delete them on screen. As all ships are deleted the level gets up by one, increasing number of ships to delete. I think the collision detection part of my program works fine, but their is some problem in their motion synchronization.
Code:
package {
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;
public class HitGame extends Sprite {
[Code] .....
the game is a little flash component found here:[URL].. i found that link here[URL].. I have been using/converting the examples they give in the second link but cant get my "missile" to behave correctly. I am using java and andEngine combo. Here is what I have right now:
[Code]...
this code just makes the object travel to the upper right hand corner of the screen and it doesnt move after that. so i am missing something
my end goal is to have an object that will chase the users touch coordinates. I know how to have the object follow such coordinates but I dont want it to follow the exact path, but rather the shortest path to the most updated coordinates. so more like an intercept course
im trying to create a basic spaceship flying game and the first problem ive got is controlling the ship.the controls i need are thrust and left-rotate and right-rotate. much like this,[URL]..at the start this tut mentions 'game control tutorials' does anyone know where these are? i think i would find these useful. the above tut doesnt go into scripting.
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 creating a game at the moment for my university course and it involves the player character jumping on top of boxs twice to break them as opposed to just once.What would be the most efficient/simple way of writing this in Actionscript 3.
I am making a space invader game as a uni project. Please seee attched file.I am getting an error:TypeError: Error #1009: Cannot access a property or method of a null object reference. at MethodInfo-19()It only happens sometimes when an invader is removed in the moveBullet method I think but basically the game behaves incorrectly and sometimes goes to the You Win frame even if the user has lost or just lost a life.
My project is almost complete except for this last little thing that's been bugging me. A tutorial I followed had you start the game by clicking a button but I would like to change that to pressing the spacebar starts the game. I tried:
I just can't figure out why a simple movieclip is not performing as expected.
Here's what happened:
In my MAIN SCREEN, I placed a a movieclip and named it "mainnav_mc" and on my ACTIONS layer, I placed a script on the frame that will eventually play the movie "mainnav_mc". This is the script: mainnav_mc.gotoAndPlay("show");The clip is suppose to fade-in but it seems that MOTION TWEEN is not working. I tried to create a test MC and still it's not working.
how to make a Space Invaders game (with a twist). I have previously made a game in Actionscript 1.0, which may be viewed at [URL] (press S to start the game after typing in your name).
I want to use this project as an exercise for learning AS 3.0, and I a cannot really see how I need to use separate AS files (Actionscript classes)
I am currently working on a new game and I need help on this part. It is probably simple to do but I am a noob. Basically I am making a window cleaning game and I have set it up so that the dirt slowly dissapears through the frames. What I need to know is how to I script it so that each time I press space it jumps to each frame.
e.g hit space jump to frame 2 press again jumps to next frame.I know How to set up the key press and know space is 32..
trying to color objects that are flying around in my space game.When I shoot and hit them - the affected enemies shall blink. The graphics are pre-rendered (i.e. there's an rotation array and function where the degrees and their appropriate rotation for the objects are stored / calculated for better performance).
So - my idea was to enhance that rotation function with a functionality for additional coloring; but the colored AND rotated objects shall be stored apart of the normal rotated objects. To accomplish this I made a nested array:in row one there are 360 rotated graphics of one object and in row two there are 360 graphics of a rotated and colored object.
Problem: Coloring works but they are not rotated (always at 0 degrees).
Code: public function createRotationWithColorBlitArrayFromBD(sourceBitmapData:BitmapData, inc:int, offset:int = 0):Array { trace("sourceBitmapData.width=" + sourceBitmapData.width);
I am making my first game and it's my first time using actionscript. I am making a sniper game themed with the L96A1 sniper rifle from COD: Black Ops and the map nuketown. I'm in cs5 with ac3 and on my stage I have two movie clips that I'm working with. I'm not really sure if they're supposed to be movie clips though. Anyways, one is the gun, and the other is the zoomed in scope overlay thingy.
For now, I'm trying get the zooming in to work. I haven't done anything else though except collect graphics for enemies, the landscape, the gun, and the scope. I want to make it so that you zoom in and out by holding and letting go of the space bar. Also,I want to make it so that when you are not zoomed in, the gun moves horizontally at the bottom of the screen (aligned vertically with the cursor). And when you are zoomed in, the scope crosshair is the cursor.So my idea was to set the gun as the cursor and make it only move horizontally at the bottom of the stage and then make an event listener that listens to when the spacebar is pressed and when it is, disables the gun as the cursor (and makes it transparent to get it off the screen) and makes the scope the cursor [was transparent, now opaque and unrestricted(vertical movement also)].
I got as far as making the gun move horizontally at the bottom with the cursor. I cant get the event listener working because I don't really know how to go about changing the opacity of each movie clip and how to switch cursors. So I am asking how do I change the opacity and switch the cursors when the spacebar is held and then reverse those changes when the spacebar is released? Here's my code on an "actions" layer [I haven't done any animations yet, so everything is on frame 1. Also, I used a couple preset code snippets since I have no previous experience with actionscript (I can understand most of it though)]:
Code: import flash.events.KeyboardEvent; // make gun cursor stage.addChild(gun);[code]..........
Here's a link to a zip archive with all the files used so far (I hope this google docs link works): link
I've been following a tutorial on [URL] but changing and removing various things to fit to the game I am (very, very slowly) trying to make. I am attempting to make an up-side-down Space Invaders like game, but with balloons instead of aliens.
So far (by following the tutorials and being lucky) I have managed to make the player's ship which moves by pressing the arrow keys and can shoot two (blue) lasers when the spacebar is pressed. The enemy balloons randomly appear below the bottom of the screen and shoot a laser upwards towards the player's ship when the player goes above (Y axis I think) any balloons.
The problem is that the balloons fire a massive stream of shots (red lasers), but I want to delay each next shot by a few seconds, but the time of the delay doesn't matter because I'll tweak it later.
I've been trying to make delays for the balloon lasers by copy/pasting bits of code from Ship.as in an attempt to make it work ...Maybe it's a good time to say I am a complete noob at AS3 apart from when it comes to messing up and having no idea what is going on
I've attached my current (broken) work and a working SWF of before trying to add delays to the balloons shots. If you want to see it working first hand then replace the Balloon.as in actionscript.game with the Balloon(working).as and change the filename to Balloon.as.
how to make a simple ball follow an oval motion path? Think of a molecule spinning (and looping) around a nucleus. This was five seconds work in previous versions where you could draw the motion guide then simply attach an object to it and say "orient to path" but I can't seem to find how to do it in CS4.
The problem is: when the game starts, "SPACE BAR" is working fine and changes the game from day to night. When the game ends and I press restart, the SPACE key is not working. On the third time it works, on the fourth not and it follows that way. Every second time that I play the game, the SPACE key doesn't work.
The game initializes the player and sends him as a parameter a stage object and the player listens for KEY_UP.When I press restart, the game runs the init() function again.Below there are the Game.as and Player.as classes.
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 sort of new to Flash, have been using it for ages but just to animate, i haven't done any programming or interactive stuff for years, so i feel new to it again!Creating a very simple platform.Movie clip of the character (instance name z_1)- runs button - when pressed makes z_1 invisible and loads another movieclip of him firing a weapon (z_fire). (also makes ground stop moving- basically game is a static running animation, over a moving ground, if that makes sense)This all works fine, i even figured how to make the score increase!After the firing animation is finished (there is a stop on the movieclip) i want the original running animation to be visible again and for the ground etc to play again. The firing animation is only 12 frames long so i imagine i need to tell the button to resume normal service on the stage after that time period![code]It's probably completely wrong but it works, i just need to know the extra code to make the original animations start back again after z_fire has played.
I'm looking to build a very simple (hopefully!) interactive game.
- A number of balls are situated at the bottom of the stage.
- There are several dropzones which the balls can be placed in.
-Once a dropzone is occupied with a ball, its not possible to populate that the dropzone with another ball until the present one has been removed. -Depending on which balls are present in the dropzones, the balls animate differently. the red ball is placed in a dropzone. There are currently no other dropzones populated with a ball.
I just want to create a simple timer for a car game which notes the lap time each time you cross the finish line. I then want to be able to use the "gotoAndPlay (frame number)" once either a certain amount of laps have been completed or when the timer hits a specified number.I have exhausted tutorials, none of which actually work - what im looking for is 'i think' actually quite simple but i am having great difficulty.... The car game tutorial with 4 parts which seems to pop up everywhere does not help as it is very complex and can only be used when the game is designed in the way that the guys has made it.
I am developing a Jeopardy-like game in Flash CS5. I am familiar with Flash CS5, but new to AS3. I don't know the language well, and to top it off my code hints don't work in Flash CS5. After researching this I've learned it is a bug that Adobe has yet to resolve. Anyway I am trying to program this game with very little knowledge about the language I am using. I've been watching tutorials and googling specific questions, but it comes down to the fact that I don't speak the language and don't have the resource (code hints) to make the language more available to me.What I am trying to do is simple:Imagine a Jeopardy game board.On the answer screen there is a button that takes you back to the gameboard. Here's the catch: the gameboard must remember which boxes have been chosen and not display those dollar values.
I understand how to program the buttons. I've been using gotoandstop for that. I am trying to figure out the best way to program this so the game remembers which boxes have already been chosen throughout the entire game.The specific question I have at the moment is how to reference an instance on another frame than the frame that has the code on it. For example: The gameboard is on frame 5. When the category A for $200 box (buttonA1) is clicked a Boolean var called 'chosen' is created and assigned the value of true. then the gotoandStop command moves the game to frame 10 which is where the question for category A for $200 lives. There is a button on frame 10 that takes you to the answer, which is on frame 11. And on frame 11, when you click on the button to take you back to the gameboard, I want it so that if chosen = true then buttonA1.visible = false. I get an error because buttonA1 doesn't exist on frame 11 - it lives on frame 5 and I have no idea how to reference it so that it will not be visible.
Make a simple Multiplayer game (Java server, AS3 client) and i was wondering, how would i get people to be able to select their clothing?
Im going to have the data stored in a database, but i want to know, how would i go about keeping a shirt/pants/shoes of each colour and merging them (For each character's combination) to create a new movieclip (username_figure for example)
I have tried to create a simple Hangman game, it works great, but I have two problems. Number one, the course I�m taking requires that there should be an if else statement in the actionscript programming (in an appropriate manner in connection with the user interaction) and I realy don�t know how to fix that. I�m tearing my hair. Number 2 Preferably I would like the program, alternating between several different words.
I want to create a really basic pac man style maze game, its actually for some marketing materials and it will be really used as means of navigation rather than as a game, I want pac mac to eat certain words and when that happens it will tell the user about that topic. What the best way for pac man to work his way around the maze would be? Would I be best using hit detection? Also what would be the best way to remove the pellets as he eats them? visibility or remove child?
I'm working on a project with an Arduino microcontroller connected to LED's and using flash to turn the LED's on and off via a serial proxy and a special ActionScript 3 library. The program loads an MP3 and I use the time position of the song to tell the program when and which LED's to control. My issue is that I am using if statements for the control and I know that is very inefficient.[code]The variable pos is the time of the song. Pin LOW is light off and pin HIGH is on. I repeat this every time I want the lights to change so there are over 100 if statements. There are 6 pins/LED's.I know you can do this with an array but have no idea how to get started.
I would like to draw a shape with LineTo (following a motion guide) and having this drawing synchronize to the duration of a sound : if the sound lasts 2 minuts, the drawing should take 2 minuts to be drawn.
