Hey guys,
I’m having a problem with what I think might be a sync with framerate problem.
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.BitmapData;
import flash.display.Bitmap;
public class Curves extends MovieClip{
//GlobalSpeed
public static var GlobalSpeed:int = 1;
//Blitting variables
public var CANVAS_BD:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight, false, 0x00FF0F);
public var CANVAS_BITMAP:Bitmap = new Bitmap(CANVAS_BD);
public var BACKGROUND_BD:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight, false, 0x000000);
public var DOTSHEET1:DotSheet = new DotSheet();
//DotsArray properties
public var DotDiameter:int = 40;//Should be a factor of stage.stageHeight
public var DotSpacing:int = DotDiameter;//Distance between Dots Y values
public var MaxVerticalDots:int = stage.stageHeight/DotDiameter;//Max dots that can be fit on screen vertically
public var DotsArray:Array = new Array(MaxVerticalDots + 1);//+1 for one Dot to be off screen
//Cosine/sine function: Rotated -90 degrees into f(y)
public var PeriodFactor:int;
public var AmplitudeFactor:int;
public var FunctionOffset:int;
//Populate DotsArray with Dots and set (x/y)
public function SetUpDotsArray() {
for(var i = 0; i < DotsArray.length; i++) {
if(i == 0) {
DotsArray[0] = new Dot(DotDiameter/2, 0xFFFFFF);
DotsArray[0].x = stage.stageWidth/2;
DotsArray[0].y = -DotDiameter;
}
if(i > 0) {
DotsArray* = new Dot(DotDiameter/2, 0x000000);
DotsArray*.x = stage.stageWidth/2;
DotsArray*.y = DotsArray[i - 1].y - DotSpacing;
}
addChild(DotsArray*);
}
}
public function SetDotCoordinates(d:Dot) {
//First Dot, DotsArray[0], is treated differently
if(DotsArray.indexOf(d) == 0) {
//When zero needs to come back up top
if(DotsArray[0].y >= stage.stageHeight) {
//It's y value should follow that of the last element in the array
DotsArray[0].y = -DotDiameter;
}
}
if(DotsArray.indexOf(d) > 0) {
if(DotsArray[DotsArray.indexOf(d)].y >= stage.stageHeight) {
DotsArray[DotsArray.indexOf(d)].y = DotsArray[DotsArray.indexOf(d) - 1].y - DotSpacing;
}
}
}
public function MoveDots() {
//Set coordinates and move
for(var j = 0; j < DotsArray.length; j++) {
SetDotCoordinates(DotsArray[j]);
DotsArray[j].y += GlobalSpeed;
}
}
public function Curves() {
addEventListener(Event.ENTER_FRAME, MainLoop);
addChild(CANVAS_BITMAP);
SetUpDotsArray();
}
public function MainLoop(e:Event) {
MoveDots();
trace(DotsArray[0].y);
}
}
}
What I am trying to do is get these dots to loop infinitely butted up next to eachother but for some reason a gap starts forming between the first element of EnemyArray and the last element. When I change the speed and/or the framerate it only gets worse and I would ideally like to have it work regardless of framerate or speed. I hope this makes sense.
