Actionscript _Text Class

Useful functions for adding dynamic text fields. Don't forget, you have to add the font of choice into the main movie Library for this to work (Library Panel Menu > New Font). The name you give the font is the string that you pass to the getTextFormat function for the "font" parameter. Setup your font styles with getTextFormat, setup your dynamic text box with getTextField, and then add text to the text box with appendTextField.

dynamic class _Text {
	static function getTextFormat(font:String,size:Number,color:Number,leading:Number,url:String,target:String){
		var fmt:TextFormat = new TextFormat();
		fmt.font = font;
		fmt.kerning = true;
		fmt.leading = (leading != undefined && leading != null) ? leading : 0;
		fmt.bold = false;
		fmt.size = (size != undefined && size != null) ? size : 11;
		fmt.color = (color != undefined && color != null) ? color : 0x000000;

		if (url != undefined && url != null) {
			fmt.url = url;
			fmt.target = (target != undefined && target != null) ? target : "_self";
		}
		return (fmt);
	}
	
	static function getTextField(targetMC,targetDepth,txtFieldName,x,y,w,h,txtObj){
		var targetDepth = (targetDepth != undefined && targetDepth != null) ? targetDepth : targetMC.getNextHighestDepth();
		var txtfld = targetMC.createTextField(txtFieldName, targetDepth, x, y, w, h);
		txtfld.antiAliasType = (txtObj.antiAliasType) ? txtObj.antiAliasType : "advanced";
		txtfld.sharpness = (txtObj.sharpness) ? txtObj.sharpness : -60;
		txtfld.thickness = (txtObj.thickness) ? txtObj.thickness : -100;
		txtfld.embedFonts = (txtObj.embedFonts) ? txtObj.embedFonts : true;
		txtfld.selectable = (txtObj.selectable) ? txtObj.selectable : false;
		txtfld.html = (txtObj.html) ? txtObj.html : true;
		txtfld.multiline = (txtObj.multiline) ? txtObj.multiline : true;
		txtfld.autoSize = (txtObj.autoSize) ? txtObj.autoSize : "left";
		
		if (txtObj.htmlText) txtfld.htmlText = txtObj.htmlText;
		if (txtObj.txtFormat) txtfld.setTextFormat(txtObj.txtFormat);
		
		if (txtObj.wordWrap == undefined || txtObj.wordWrap == null) txtfld._width = txtfld.textWidth + 10;
		else txtfld.wordWrap = txtObj.wordWrap;
		return txtfld;
	}
	
	static function appendTextField(txtfld,txtfrmt,txt){
		var beginIndex:Number = txtfld.htmlText.length;
		txtfld.setNewTextFormat(txtfrmt);
		txtfld.replaceText(beginIndex,beginIndex,txt);

Actionscript _Draw Class

These still need tweaking, but essentially I just wanted a repeatable way to draw boxes via script. This includes the ability to add rounded corners, gradients, and drop shadows (could it really be any other way? :) The Balloon function was to fulfill a specific goal, obviously, but since these things are more and more popular I figured it would be a good idea to have it somewhat configurable for future usage. Right now, for drop shadows you just have to make two boxes, one blurry, one not. Perhaps it would be better to consolidate the balloon script into the box script, but for now, this works.

import flash.filters.BlurFilter;
dynamic class _Draw {
	
	static function box(targetMC,targetDepth,w,h,c,r,gradientType){
		var targetDepth = (targetDepth != undefined && targetDepth != null) ? targetDepth : targetMC.getNextHighestDepth();
		var newBox:MovieClip = targetMC.createEmptyMovieClip("newBox", targetDepth);
		var g:Object = new Object();
		
		if (c.length != undefined){
			g = getGradientObject(w,h,gradientType);
			newBox.beginGradientFill(g.fillType, c, g.alphas, g.ratios, g.matrix, g.spreadMethod, g.interpolationMethod, g.focalPointRatio);
		} else {
			newBox.beginFill(c);
		}
		
		if (r == undefined) var r = 0;
		
		with (newBox){
			lineStyle(0,0x000000,0);
			moveTo(r, 0);
			lineTo(w-r, 0);
			curveTo(w,0,w,r);
			lineTo(w, h-r);
			curveTo(w,h,w-r,h);			
			lineTo(r, h);
			curveTo(0,h,0,h-r);
			lineTo(0, r);
			curveTo(0,0,r,0);
			endFill();
		}
		
		return newBox;
	}

	static function balloon(targetMC,targetDepth,w,h,c,r,gradientType,arrowBaseOffset,arrowBaseWidth,arrowLength,arrowPointOffset){
		var targetDepth = (targetDepth != undefined && targetDepth != null) ? targetDepth : targetMC.getNextHighestDepth();
		var newBalloon:MovieClip = targetMC.createEmptyMovieClip("newBalloon", targetDepth);
		var g:Object = new Object();
		
		if (c.length != undefined){
			g = getGradientObject(w,h,gradientType);
			newBalloon.beginGradientFill(g.fillType, c, g.alphas, g.ratios, g.matrix, g.spreadMethod, g.interpolationMethod, g.focalPointRatio);
		} else {
			newBalloon.beginFill(c);
		}
		
		if (r == undefined) var r = 0;
		
		with (newBalloon){
			lineStyle(0,0x000000,0);
			moveTo(r, 0);
			lineTo(w-r, 0);
			curveTo(w,0,w,r);
			lineTo(w, h-r);
			curveTo(w,h,w-r,h);
			
			// start arrow			
			lineTo(r + arrowBaseOffset + arrowBaseWidth, h);
			lineTo(r + arrowBaseOffset + (arrowBaseWidth/2) + arrowPointOffset, h + arrowLength);
			lineTo(r + arrowBaseOffset, h);
			// end arrow
			
			lineTo(r, h);
			curveTo(0,h,0,h-r);
			lineTo(0, r);
			curveTo(0,0,r,0);
			endFill();
		}
		
		return newBalloon;
	}

	static function getGradientObject(w,h,gradientType){
		var gradientObj:Object = new Object();
		
		gradientObj.fillType = "linear"
		gradientObj.alphas = [100, 100];
		gradientObj.ratios = [0, 0xFF];
		gradientObj.spreadMethod = "pad";
		gradientObj.interpolationMethod = "RGB";
		gradientObj.focalPointRatio = 1;

Actionscript _Animate Class

This is basically a way to set up an animation queue to utilize scripted tweening. You would have to create external functions which carry forth the animation actions then store the function objects in the _Animate.queue Array in the sequence you wish to play them out. Ideally, these functions would return a Tween object for the sake of utilizing "onMotionStopped". Returning False (bool) will simply allow the next function in the queue to fire without checking for the onMotionStopped call. When you are ready to start the animation sequence, just call launch();

import _String;

dynamic class _Animate {
	var queue:Array;
	
	function _Animate() {
		queue = null;
	}
	
	public function caller(qNum){
		var gA = this;
		var callback = queue[qNum].func.apply(this, _String.toArray(queue[qNum].params)); qNum++;
		if (qNum < queue.length && callback) callback.onMotionStopped = function() { gA.caller(qNum); }
		else if (qNum < queue.length && !callback) gA.caller(qNum);
	}
	
	public function launch(){ caller(0); }
	
	
}

Sample Usage

var zoomIn = new _Animate();

zoomIn.queue = [
	{func:aniSidebar, params:"hide,6"},
	{func:aniMapMidFade, params:"hide,6"}
];

zoomIn.launch();

function aniSidebar(action, time){
	var leftBeginX = (action == "hide") ? 0 : 0 - sidebarLeftBg._width;
	var leftEndX = (action == "hide") ? 0 - sidebarLeftBg._width : 0;
	var rightBeginX = (action == "hide") ? Stage.width - sidebarRightBg._width : Stage.width;
	var rightEndX = (action == "hide") ? Stage.width : Stage.width - sidebarRightBg._width;
	var transition = mx.transitions.easing.Regular.easeInOut;
	var leftAni = new mx.transitions.Tween(sidebarLeftBg, "_x", transition, leftBeginX, leftEndX, time);
	var rightAni = new mx.transitions.Tween(sidebarRightBg, "_x", transition, rightBeginX, rightEndX, time);
	return rightAni;
}

function aniMapMidFade(action, time){
	var begin = (action == "hide") ? 100 : 0;
	var end = (action == "hide") ? 0 : 100;
	var transition = mx.transitions.easing.Regular.easeOut;
	var mapMidAni = new mx.transitions.Tween(mapMid, "_alpha", transition, begin, end, time);
	return mapMidAni;
}

Javascript Window OnLoad Listener

This script gives the ability to run javascript functions after the page has loaded. I definitely can't take credit for this, as it's one I found, but I use it constantly.

window.onloadListeners=new Array();

window.addOnLoadListener = function (listener) {
	window.onloadListeners[window.onloadListeners.length]=listener;
}

window.onload=function(){
	for(var i=0;i<window.onloadListeners.length;i++){
		func = window.onloadListeners[i];
		func.call();
	}
}

//window.addOnLoadListener(function);
