(I have asked this before but I dont think I was direct enough with my question and therefore it did not get resolved so here goes again!)
I am working through a book called Foundation Actionscript 3.0 Animation, making things move.
I am now on Chapter 9 - Collision Detection. On two lines of my code I get the 1135 error, letting me know that I have an incorrect number of arguments. I have highlighted the two areas in which this occurs with asterisks:
package
{
import flash.display.Sprite;
import flash.events.Event;
public class Bubbles extends Sprite
{
private var balls:Array;
private var numBalls:Number = 10;
private var centerBall:Ball;
private var bounce:Number = -1;
private var spring:Number = 0.2;
public function Bubbles()
{
init();
}
private function init():void
{
balls = new Array();
***centerBall = new Ball(100, 0xcccccc);***
addChild(centerBall);
centerBall.x = stage.stageWidth / 2;
centerBall.y = stage.stageHeight / 2;
for(var i:uint = 0; i < numBalls; i++)
{
***var ball:Ball = new Ball(Math.random() *
40 + 5,
Math.random() * 0xffffff);***
ball.x = Math.random() * stage.stageWidth;
ball.y = Math.random() * stage.stageHeight;
ball.vx = Math.random() * 6 - 3;
ball.vy = Math.random() * 6 - 3;
addChild(ball);
balls.push(ball);
}
addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
private function onEnterFrame(event:Event):void
{
for(var i:uint = 0; i < numBalls; i++)
{
var ball:Ball = balls[i];
move(ball);
var dx:Number = ball.x - centerBall.x;
var dy:Number = ball.y - centerBall.y;
var dist:Number = Math.sqrt(dx * dx + dy * dy);
var minDist:Number = ball.radius + centerBall.radius;
if(dist < minDist)
{
var angle:Number = Math.atan2(dy, dx);
var tx:Number = centerBall.x +
Math.cos(angle) * minDist;
var ty:Number = centerBall.y +
Math.sin(angle) * minDist;
ball.vx += (tx - ball.x) * spring;
ball.vy += (ty - ball.y) * spring;
}
}
}
private function move(ball:Ball):void
{
ball.x += ball.vx;
ball.y += ball.vy;
if(ball.x + ball.radius > stage.stageWidth)
{
ball.x = stage.stageWidth - ball.radius;
ball.vx *= bounce;
}
else if(ball.x - ball.radius < 0)
{
ball.x = ball.radius;
ball.vx *= bounce;
}
if(ball.y + ball.radius > stage.stageHeight)
{
ball.y = stage.stageHeight - ball.radius;
ball.vy *= bounce;
}
else if(ball.y - ball.radius < 0)
{
ball.y = ball.radius;
ball.vy *= bounce;
}
}
}
}
I think this is due to the non-existance of a Ball.as, when reading the tutorial I assumed it meant that I had to create a movie clip of a ball on stage and then export it for actionscript with the class name being Ball, however when flicking back through the book I saw that a Ball.as already existed, stating that I may need to use this again later on in the book, this read:
package
{
import flash.display.Sprite;
public class Ball extends Sprite
{
private var radius:Number;
private var color:uint;
public var vx:Number=0;
public var vy:Number=0;
public function Ball(radius:Number=40, color:uint=0xff0000)
{
this.radius=radius;
this.color=color; init();
}
public function init():void
{
graphics.beginFill(color);
graphics.drawCircle(0, 0, radius);
graphics.endFill();
}
}
}
This managed to stop all the errors appearing however, it did not transmit any of the effects from Bubbles.as it just braught a Red Ball on the center of the stage. How would I alter this code in order to work in favour of Bubbles.as?
Please Help! Thanks!
