buttons	BUTTON_NAME.addEventListener(MouseEvent.MOUSE_UP,clicked); function clicked(e:MouseEvent) { gotoAndPlay("FRAME_LABEL"); }
buton for sound	BUTTON_NAME.addEventListener(MouseEvent.MOUSE_DOWN,clicked); function clicked(e:MouseEvent) { var mySound = new Sound; mySound.load(new URLRequest("FILE_NAME.mp3")); mySound.play(); }
button for random sounds	BUTTON_NAME.addEventListener(MouseEvent.MOUSE_DOWN,clicked); function clicked(e:MouseEvent) { var list = ["NAME1","NAME2,etc"]; var mySound = new Sound; mySound.load(new URLRequest(list[Math.floor(Math.random()*(NUMBER_OF_SOUNDS))])); mySound.play(); }
load one SWF	import flash.net.URLRequest; import flash.display.Loader; import flash.events.Event; import flash.events.ProgressEvent; var thing1 = null; var loaded = 0; final var totalIndicies = 2; function startLoad() { var mLoader:Loader = new Loader(); var mRequest:URLRequest = new URLRequest('square.swf'); mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler); mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler); mLoader.load(mRequest); } function onCompleteHandler(loadEvent:Event) { stage.addChild(loadEvent.currentTarget.content); thing1=loadEvent.currentTarget.content; fixDepth(1); } function onProgressHandler(mProgress:ProgressEvent) { var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal; trace(percent); } function fixDepth(index:int) { loaded += index; if(loaded==totalIndicies) { stage.setChildIndex(thing1, stage.numChildren-1); } } startLoad();
load 2 SWF's	import flash.net.URLRequest; import flash.display.Loader; import flash.events.Event; import flash.events.ProgressEvent; var thing1 = null; var thing2 = null; var loaded = 0; final var totalIndicies = 3; function startLoad() { var mLoader:Loader = new Loader(); var sLoader:Loader = new Loader(); var mRequest:URLRequest = new URLRequest('square.swf'); var sRequest:URLRequest = new URLRequest('square2.swf'); mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler); sLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, done); mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler); mLoader.load(mRequest); sLoader.load(sRequest); } function onCompleteHandler(loadEvent:Event) { stage.addChild(loadEvent.currentTarget.content); thing1=loadEvent.currentTarget.content; fixDepth(1); } function done(loadEvent:Event) { stage.addChild(loadEvent.currentTarget.content); thing2=loadEvent.currentTarget.content fixDepth(2); } function onProgressHandler(mProgress:ProgressEvent) { var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal; trace(percent); } function fixDepth(index:int) { loaded += index; if(loaded==totalIndicies) { stage.setChildIndex(thing2, stage.numChildren-1); stage.setChildIndex(thing1, stage.numChildren-1); } } startLoad(); stage.removeChild(thing1);
unload SWFfrom above	stage.removeChild(thing1);
Stop Sound	SoundMixer.stopAll(); /* or*/ soundchannelname.stop();
Key Movement (in actions frame)	import flash.ui.Keyboard; import flash.events.Event; import flash.events.KeyboardEvent; // add the event listeners myExample.addEventListener(Event.ENTER_FRAME, update); stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown); stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp); // this array holds references to all the keys var keys:Array = []; // the event listeners function update(e:Event):void { if (keys[Keyboard.RIGHT]) { myExample.x += 5; } if (keys[Keyboard.LEFT]) { myExample.x -= 5; } if (keys[Keyboard.UP]) { myExample.y -= 5; } if (keys[Keyboard.DOWN]) { myExample.y += 5; } } function onKeyDown(e:KeyboardEvent):void { keys[e.keyCode] = true; } function onKeyUp(e:KeyboardEvent):void { keys[e.keyCode] = false; }
Key Movement (Paste to clip)	import flash.events.KeyboardEvent; import flash.events.Event; import flash.ui.Keyboard; //add event when a key is pressed stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler); //add event when a key is released stage.addEventListener(KeyboardEvent.KEY_UP, KeyUpHandler); //add event that will fire on the framerate addEventListener(Event.ENTER_FRAME, EnterFrameHandler); var xAcceleration :Number = 0; //x acceleration var yAcceleration :Number = 0; //y acceleration var xSpeed:Number = 0; //speed on the X axis var ySpeed:Number = 0; //speed on the Y axis //based on the keys that are down set the acceleration function keyDownHandler(event:KeyboardEvent):void { if(event.keyCode == Keyboard.LEFT) { xAcceleration = -1; } else if(event.keyCode == Keyboard.RIGHT) { xAcceleration = 1; } else if(event.keyCode == Keyboard.UP) { yAcceleration = -1; } else if(event.keyCode == Keyboard.DOWN) { yAcceleration = 1; } } //when a key is released set the acceleration to 0 function KeyUpHandler(event:KeyboardEvent):void { if(event.keyCode == Keyboard.LEFT \|\| event.keyCode == Keyboard.RIGHT) { xAcceleration = 0; } else if(event.keyCode == Keyboard.UP \|\| event.keyCode == Keyboard.DOWN) { yAcceleration = 0; } } function EnterFrameHandler(event:Event):void { xSpeed += xAcceleration ; //increase the speed by the acceleration ySpeed += yAcceleration ; //increase the speed by the acceleration xSpeed = 0.95; //apply friction ySpeed = 0.95; //so the speed lowers after time if(Math.abs(xSpeed) < 0.02) //if the speed is really low { xSpeed = 0; //set it to 0 //Otherwise I'd go very small but never really 0 } if(Math.abs(ySpeed) < 0.02) //same for the y speed { ySpeed = 0; } xSpeed = Math.max(Math.min(xSpeed, 10), -10); //dont let the speed get bigger as 10 ySpeed = Math.max(Math.min(ySpeed, 10), -10); //and dont let it get lower than -10 this.x += xSpeed; //increase the position by the speed this.y += ySpeed; //idem }
