Actionscript :: Keep A Bouncing Ball Centered In Stage?
Mar 8, 2011I have a ball bouncing on a paddle. I want the "stage" to move vertically in order to always keep the ball centered.

View 2 RepliesWhen I bounce a ball off the walls of the stage using the following technique.[code]Not only is the ball jumpy and skippy. but after so often it begins to go either in a vertal motion y = 5; x = 0; or a horzontal motion x = 5, y = 0. And stays that way. Why is it that the first method works fine but the other method works terrible. Could it be because the Math.cos and Math.sin returns very large decimals.I really prefer to use the second method.
View 5 RepliesI have recently started Learning Actionscript 3.0 out of my own interest. I was trying on making a ball bounce off the edges of the stage using the Actionscript 3.0. But the code not working. The Ball happens to move on X and Y, till it hits the end of the stage, and then it just does not reverse its direction to give the effect of bounce, it gets stuck to the X axis and moves out of the stage. I tried to make changes, but failed.
Code:
function bounceBall(evt:Event):void {
var vx:Number=Math.random()*10+5;
var vy:Number=Math.random()*10+5;
var radius:Number=mcBall.height/2;
var top:Number=0;

I have added full screen code on my movie so that the user can extend the size of the movie. eg If the user expands the browser window to 1200 X 900, then my movie will become 1200 X 900 without the movie deforming.
Code:
Stage.scaleMode = "noScale";
Stage.align = "TL";

i wanna ask how do i make a ball bounce off something like a ball bouncing off a bumper in a pinball game? i've tried a lot of times but everytime the ball get stucked to the box and it doesn't move anymore...will be grateful if anyone noes the actionscript of it..
View 3 Repliesi have just came across the tutorial with physics/bouncing ball - so far i have encountered no problems in understanding it, but just a question:how do i stop the ball bouncing? do i have to equal it to a certain value or just drop in another if/else statement, because now the ball seems to bounce forever, since it gets every time multpilicated by a negative number.
View 2 Repliesim was wondering if anyone knows the script for a ball bouncing off a paddle. I want the ball to bounce off the paddle in different directions depending on:
1) which side of the paddle it hits
2) which direction it came from
Ive only got this so far : script for the paddle
onClipEvent(enterFrame)
{
if (this.hitTest(_parent.ball)) //if this movieclip hits the movieclip 'ball'
tellTarget(_root.ball) //tell the ball to:[code]....
I have created a flash AS3 file with two movieclips. One is a ball (ball_mc) and a wall (wall_mc). The ball bounces around off the outer walls of the stage, in horizontal lines.
The ball also changes direction if it bounces off the wall. However its not bouncing off the wall in the right direction?
Code:
var dx:Number=3; //the amount the ball will move horizontally each frame
var dy:Number=5; //the amount the ball will move vertically each frame
this.addEventListener(Event.ENTER_FRAME,moveBall); // call the function moveBall every frame

below is the code I am useing I have created a simple frame with 2 layers one named body and one named Code in the code frame I have
[Code]...
In the body I have 4 walls all named top bottom right and left they are movies and they are named in there instance the same I have a circle I named ball and made it into a movie and named it ball yet when I run the flash file the ball flys off the page and doesnt bounce inside the boxes?
I am currently making a brick breaker game, so I want to make the ball bounce from the paddle. My paddle's name is pwn and the ball's name is ball.
My code for ball is currently:
onClipEvent (enterFrame) {
this._y += 5;
this._x += 4;
}

I just want the ball to bounce somewhere else other than stopping the ball at the place. I already made sure the paddle can move and the boundaries block the paddle from leaving the stage. So can someone give me the codes (please simple for me to copy-paste) for having me to bounce the ball some opposite direction or whatsoever. Like once the ball touches the paddle, it reflects somewhere else at the same speed and a different direction without any errors.
What I need is a ball to be bouncing. It needs it needs to slow down when it reaches its peak and increase speed as it falls. It needs to bounce forever at the same height. And last ... I need a button to make the ball look like its moving in slow motion (while still bouncing at the same height).
This is the closest I have come to getting it right. if you click the button when the ball is at its peak it works. but if you click any other time the ball will fly up to far (it needs to bounce the same height when in slow motion and in regular motion).
movieclips - "ball", "ground"
button - "btn"

View 0 RepliesI'm looking for a bouncing ball script, but one which is easily editable. I'm not a coder of any sort, but I can work out small sections of script.Basically, I want somewhere to set the number of balls, somewhere to set the speed and somewhere to set rotation. The objects I will be using will not be completely spherical, and need to look natural as they bounce off each other and off the walls, rotating as they do so.So, to clarify, I need an actionscript file that:
* Allows me to create objects that will bounce off all four walls. Gravity isn't a requirement.
* Allows me to create objects that have collision detection, allowing them to bounce off each other and rotate as they do so.
* Allows me to have the objects bouncing as soon as the flash file plays. In other words, clicking and dragging is not a requirement.
* Allows me to create x amount of objects at a randomised size.
* Allows me to specify the speed of the objects.
* Allows me to specify the rotation speed of the objects.
trying to basically using AS3 to make a ball bounce around the stage but never lose motion and have the chance to speed it up or slow it down through code.
View 3 RepliesI'm using the actionscript below to Move Object Using The Arrow Keys and it works fine but I want to modify it so that when I press the up key it goes to and play a movie clip. Basically it's a ball movie clip that responds to the arrow key but on the up key it plays a bouncing movieclip and everything remains aligned.
Here is the script-
var speed =5;
this.onEnterFrame =function(){
if(Key.isDown(Key.UP)) {
circle._y -= speed;
} if(Key.isDown(Key.DOWN)) {
circle._y += speed;
} if(Key.isDown(Key.LEFT)) {
circle._x -= speed;
} if(Key.isDown(Key.RIGHT)) {
circle._x += speed;
}};
trying to animate the ball in 3d space. Is there a formula for this?
var xPos:Number = tennis_ball.x;
var yPos:Number = tennis_ball.y;
var xVel:Number = (Math.random() * 10) - 5;

how to stop a ball from bouncing up and down when I grab the ball with my cursor?Currently, I have two sections of code, one for a drop and drag, and one to reenact the effects of gravity on my ball.I don't want the ball to start bouncing right away,I want it to either start bouncing when I drag it and let go, or start bouncing when I click a button.I would also like it to STOP bouncing altogether if I grab the ball. (because even though I can drag it around, the bouncing animation is still running!)Here's my current code: (With one "ball_mc" on the stage)
// creating some gravity
var spring:Number=.1;
var frizione:Number=.98;[code]........
I have a ball bouncing that works great. What I want is a button that will make the ball look like its in slow motion (while still bouncing at the same height) and another button to put it back in regular motion. After hours of experimenting I still couldn't get it perfect. The following code is on the ball movieclip.
Code:
onClipEvent (load) {
var acceleration = 0.005;
var termVelocity = 20;
[Code]......
So in my level 1, here's what I wanted it to look like:on enter frame, a few of my "drag-gable" buttons are going to fall to the ground, bounce a little bit and stop when they ran out of speed.Attached the file that I've already scripted the drag n drop on each button, now how do i script the "fall to the ground part"?
View 0 RepliesI am trying to work out a way to achieve the bouncing ball effect over text known from karaoke players? I would like this to be done programmatically with actionscript, so the ball follows the text and the soundfile (looking for pauses or DB rises?maybe not). I have heard its a question of finding the right algorithm? Its use will be in a language lab-like flash app based on Communication server, where the user can :
1) Hear the correct pronunciation of a sentence (with bouncing ball over text)
2) Record their own voice
3) Compare the two
Do you know any tutorial similar to this one [URL]...y=ActionScript) that shows how to make a bouncing image that resizes during bouncing?
View 3 RepliesIm having multiple movieclips moving randomly and bouncing of the stage border, however, my problem is, first of all that the movieclips get half their body into the border on the right and top, and on the left and bottom the movieclip stops before the border. My other problem is that the movieclips have a tendency to get stuck in the border and just bounce rapidly along the border side. Im gonna asume that i only need to show you the code which the bounce back at border is created not to make the code to long (so hopefully im right):

How do I import a .swf so that the entire thing--all 50 frames of it in the case of the animation I'm importing--is centered on the Flash Stage? (I am using CS5). When I import it now it's automatically positioned in the upper left corner of the stage. And when I try to select all frames and align it to the center in the properties manager it will only center one frame of the 50-frame .swf at a time.
View 5 RepliesI am trying to centre my flash site I have used the following code:
stage.scaleMode = StageScaleMode.NO_BORDER;
stage.align = StageAlign.TOP;
My first scene which is a intro clip, containing motion tweens of text, works fine but when I click enter and get to my site as soon as I move the resizer on my browser my stage jumps far off the page and I can only see the bottom of it.
I hav movieclips in a flash document that i have autocenter when the stage is scaled code is something like this:
clients_mc.y = Math.round((stage.stageHeight/2)-15);
stage.addEventListener(Event.RESIZE, resizeClients);
function resizeClients(event = null){
clients_mc.y = Math.round((stage.stageHeight/2)-15);
};
any way to make it esae in to position or bounce, something?
I have this code to make a ball bounce. it works fine, however, everything on the stage bounces. I only want the ball to bounce.

var gravity = 2;
var speed = 0.03;
var ground = 300;

I have a movie clip on the stage with the instance name "ball". In my code, I addChild(ball) to a Ball object called "mainBall". After doing that, I want to remove "ball" from the stage. Finally, I add addChild(mainBall) to stage. The code takes place in my Document class:
var mainBall:MovieClip = new Ball()mainBall.addChild(ball)stage
.removeChild(ball)addChild(mainBall)
From the code, I get the error: "The supplied DisplayObject must be a child of the caller".
