ActionScript 3.0 :: Create A Sine Wave With Any Given Angle Between 2 Points?
Jan 24, 2012As you can tell from the title I am not very good at math ( sigh ).
Is there a way I can create a sine wave with any given angle between 2 points ?

I want to be able to take a general sine wave y=Math.sin(x) and rotate it around some other angle, so instead of going strictly left-to-right, I'd like to go from, say, the top left corner toward the "center," or from the bottom right to the center, or any other arbitrary angle. Like this: I want to be able to use that wave as a "path" for enemies in a game, but I cannot seem to wrap my head around it. I've tried matrix transformations, but I was missing something there, too, because the origin was wrong.

(sine path)I m trying to do this for a week and cant get it good.I want to make the curves random. and acceleration too.(it will be a fish like character swimming)Like as in this game : http:[url]..........(the small character which swim and move smoothly)this is the portion of code im using now.
var tempEnemy:MovieClip = _root.attachMovie("enemy1","enemy_1,1);
tempEnemy._x = 500;
tempEnemy._y = 0;[code]..........

I have a logo that I made in Fireworks, and it looks decent, but I was wondering if anyone could mimic it with movement. For example, if someone could use actionscript to make it "wiggle" or wave like a flag in the wind, that would be awesome.
Notice how the blue line itself stays at about the same thickness (it barely starts getting thicker), but the shading around it thickens as it goes more and more to the right.

I'm generating a sine wave and playing it as a sound. But When I call SoundMixer.StopAll() it's causing a click when sounds stops. I think its because it's cutting the sound off in the middle of the wave, I was wondering of a way to make the sine wave slowly ripple out before i stop it. Is there already functions to do this in Action Script 3 or is my sine wave function i need to modify here is my code for the wave.
function sineWave(event:SampleDataEvent):void { var sample:Number for (var i:int=0; i<8192; i++) { sample = Math.sin((i+event.position) * ((2 * Math.PI)/44100) * freq); // freq is just any frequency event.data.writeFloat(sample * .15); event.data.writeFloat(sample * .15); } }
There are a couple of problems i'm having with this - the first is how to work out how to find where the tip of each sine curve is (ie the frequency) and the second is to work out how to rotate each object so that it slides sideways along the sine wave(note file is 800 x 600)here's my code: CarouselTest.as:
package
{
import com.greensock.easing.Sine;

I am sooooooooo lost. I need help in making a movie clip go in a wave motion with only action script. basically I am trying to make a game and I am so lost on how to make the enemy come in and fly in a wave motion from the left to the right in an up and down motion. I thought it would be easy but I must be using the wrong code since my enemy plane is just fly from left to right and not going up and down.

With Keith Peter's "Actionscript 3.0 Animation" book it's dead easy to make one that oscillates smoothly between two fixed values but I need one that varies it's oscillation randomly (within reason of course). Imagine the teeth of a saw, up-down-up-down-up-down, very dull. What I want is more like a range of mountains, the same smooth change in height but less regular.

View 2 RepliesI'm trying to create a loop which generates a single series of sine results ranging from 0 to 1 based on 100 loops ( ie 0 ,0.011 ,0.1111........up to 1 in a single run)The results I want start at 0 and increment in a series up to 1 and then stop. I suppose this would be one half of a sine wave I have tried the following but it goes from 0 to 1 ,1 to 0 , 0 to 1 etc whereas I want a single straight run of 100 values from 0 to 1
I tried :
for(var i:Number=0;i<=100;i++){
trace((0.5*Math.sin(i)) + 0.5);
}
This does not work.

I am developing a game for mobile in AIR (as3). I have created some bots for this game that initially just wander around. But when a bonus enters the stage, they have to move to the bonus.The detection of a new bonus and moving of the bots works fine, but there is something wrong with the manipulation when a new bonus enters the stage.Basically, this is how it works (or I try to make it work):My bot moves along with his rotation as a parameter. (works fine)
private function moveToNextLocation():void
{
var angle:Number = _rotation * 0.0174532925; // 1 degree = 0.0174532925 radians
var speedX:Number = Math.sin(angle) * _speed;

What would be a good way to create a sin wave motion using the math, not tween, class? In maya it was quite simple with sin(value) but I can't seem to get a decent undulation out of Flash. The case I'm working on is a bubble generator, you know, just for kicks. That fish tank screen saver has the bubbles moving in a sin wave it seems, looks like it works well enough.

View 4 RepliesI'm creating a group of sliders that control the opacity of several MCs in the .fla file. Right now they move straight up or down, along the y axis. However, I would like to be able to customize the angle that each moves at (e.g., tilt slider01 45 degrees, slider 02 50 degrees, etc.).
I'm assuming that I would have to create a custom math class to do this, but I have no idea what logic to go off.
The class for my sliders is below.
Code:
package
{
import flash.display.MovieClip;
import flash.display.*;

I found a basic example of how to create something that'll shoot an object and create an arc based on an angle. I added a power Bar to it, but I noticed something bad about it.
The way it works the higher the speed is the further it goes and the faster it moves across the screen. This doesn't give me enough control. Because essentially I want fast moving projectiles but I want to also be able to shoot both near and far.
With this current system that's an impossibility.. Can anyone shed some light on how I can do this better? Here's the current way it's being done (important parts):
Code:
bullet = new Bullet;
this.stage.addChild(bullet);
bullet.speed = 1 + powerBar.scaleX * 20;
[Code].....
Ive made this rotation with AS. But Id like to make the bar to move from angle A to angle B smoothly.
How can I do this?
Hi,I'm trying to use NetStreamPlayTransitions.SWITCH to create a multi angle view that switches between video streams. The issue I'm having is that NetStream.Play.TransitionComplete is called only after the buffer for the video before it is used up(this makes sense when using SWITCH to go between bandwidths but that's not what i'm using it for). Is there a way to force this switch before the buffer of the previous video is used up?
I've looked into SWAP but I can't really find any documentation on it. What I ideally would have happen is the next video in the array is triggered, that video is buffered and when there is enough to play it the stream switches to that one. SWITCH works really nice because there is no jump in switching when it's played but I just don't want the buffer to play out before the switch.Is there a way of maybe clearing the buffer of the playing video before i call SWITCH so it transitions quickly?
I need to create a line drawn between 2 points. My actual idea is of joining 3 points with lines drawn dynamically(for a triangle).
View 1 RepliesI've got a continuous plane (2-D) containing polygonal obstacles. I am uniformly sampling the plane at discrete positions to create a uniform grid of points. The grid does not have points where obstacles lie (i.e. holes where ever an obstacle is) as shown in the image below.[url]...
View 1 RepliesI want to create a simple array of points, representing a clockwise set of coordinates at 45 degree increments, such that the array would be (starting from 12 o'clock):
var coordArray : Array = [
new Point(0,-1),
new Point(1,-1),
new Point(1,0),[code]........
I'm looking for the most efficient way of creating this array (ideally with the coordinates themselves generated through some sort of equation). What's the best way to do this? All I want to do with these is create a coordinate on the stage relative to the clips current coordinate in which to move, based on that clips, such that if the move distance for clips was 50px, and the clip had a depth of 0, it would move 50px in the coordArray[0] position, or 0*50 in the x direction, and -50px in the y direction (0,-1).
I am developing a mini flash game. Player control character and move left and right to collect money coin. There are 5 points that money and bomb release and move from top to bottom. When character collide with money then increase money else hit bomb age increase by 1. Once the age is 99, the game is over and the money is the final scores
Here is my code:
package Class {
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.events.MouseEvent;
import flash.media.Sound;
[Code] .....
This is my Game:
Currently, the bomb and money random appear X, 100 with 15 money and 10 bombs in a screen.
What I want is, how to amend it become money and bomb appear from specific point, after that the money and bomb when hit the wall will bounce back.
