1. Download Red5 (be sure to get the ZIP form, not the DMG!)
2. Unzip and place in Applications directory
3. Open Terminal, navigate to your red5 directory (ex. cd /Applications/red5-0.9.0/)
4. Run the Red5 shell script with: sh ./red5.sh
5. Verify that it is running by visiting: http://localhost:5080 and click Install to install sample apps

The code in the document class of the main .fla file:

package {
 
	import flash.net.URLRequest;
	import flash.display.Loader;
	import flash.display.Sprite;
	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.events.MouseEvent;
	import flash.events.ProgressEvent;
 
 
	public class Main extends Sprite {
 
		private var mc_screen:MovieClip;
 
		public function Main(){
			startLoad();
		}
 
		private function pressedKeyboard(myEvent:MouseEvent):void{
			mc_screen.compute();
		}
 
		private function startLoad()
		{
			var swfLoad:Loader = new Loader();
			var swfRequest:URLRequest = new URLRequest("http://flashart.ca/wp-content/uploads/2009/06/compScreen.swf");
			swfLoad.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
			swfLoad.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
			swfLoad.load(swfRequest);
		}
 
		private function onCompleteHandler(loadEvent:Event)
		{
			mc_screen = loadEvent.currentTarget.content;
			addChild(mc_screen);
 
			mc_screen.x = 50;
			mc_screen.y = 94;
 
			b_keyboard.addEventListener(MouseEvent.MOUSE_DOWN, pressedKeyboard);
 
		}
 
		private function onProgressHandler(mProgress:ProgressEvent)
		{
 
			var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
			trace(percent);
 
		}
 
	}
}

And the source for the child swf’s document class (CompScreen.as):

package {
 
	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.filters.GlowFilter;
 
	public class CompScreen extends MovieClip{
 
		private var isComputing:Boolean = false;
		private var counter:uint = 0;
		private var myString:String = new String();
 
		public function CompScreen(){
 
			txt_box.filters = [new GlowFilter(0xFFFFFF, 1, 1)];
			addEventListener(Event.ENTER_FRAME, update);
 
		}
 
		public function compute():void{
 
			trace("ROTATE");
			counter = 0;
			isComputing = true;
 
		}
 
		private function update(myEvent:Event):void{
 
			if (isComputing == true){
				counter++;
				txt_box.text = String(Math.random()*999999999999999999999)+String(Math.random()*99999999);

There are many instances where interacting with a computer via keyboard and mouse just doesn’t cut it. The Arduino is a mini-computer that can be used to take inputs from things like light and motion sensors, ultrasonic range detectors, touch sensors etc, and stream that data out to a computer that visualizes it using Flash. It can also be used in the inverse scenario where Flash is telling the Arduino to turn on outputs like motors, lights, or any other electromechanical contraption.

First you need to setup the Arduino. Download the software here (Get the one at the bottom called Serial Proxy).

Next you need a program to run on your Arduino. This sample program works with analog sensors like potentiometers, IR range sensors, sonar etc.
Copy this code into a new Arduino sketch:

/*
* Sample Program for reading an analog sensor such as a potentiometer, IR range detector, sonar etc.
*/
#define anIn 2 // sensor pin
int iAnVal;  // sensor value
 
void setup() {
 
Serial.begin(19200);
 
}
 
void loop() {
 
  iAnVal = analogRead(anIn);   // read a value from the sensor
  Serial.println(iAnVal); // output value to serial
 
  delay(30);
 
}

Upload your Arduino code to the Arduino. After it starts running it will be sending out a stream of sensor data via serial to a computer. However Flash cannot directly access this information. You need what is called a serial proxy to run alongside your Flash file to transform the data coming into the computer from the Arduino into a form that Flash can work with. There are many serial proxy programs out there, but probably the most straight forward approach is to use the Arduino software’s built in serial proxy feature. Click on the button on the far right of the main toolbar to activate the proxy.

Now you should see your sensor streaming data out at the bottom. An important consideration is speed of conversation between the arduino and your computer. This is called the baud rate in the context of serial communication. You need to make sure that whichever baud rate you use, both the Arduino and the serial proxy are speaking to each other at the same speed. Change the baud rate with the pull-down menu near the bottom right. Since in the code we set the baud rate to 19200, select that number from the pull-down.

Also take note of the port number that is stated in the section above (in this case port 11100). Your actionscript code will need to have this port number for the serial proxy to talk to Flash.

Download this flash source file. It is already configured to read data on port 11100. This file is expecting to see a number between 0-512 in the serial data stream from a device like the Maxbotix EZ1 so you will have to modify it if your analog sensor is putting out higher numbers. The swf will simply scrub the timeline of a rectangle movieclip based on the numbers coming in. You may wish to experiment with the smoothInt variable which combines the incoming data with past data to smooth out any irregular numbers coming through the data stream.

Nice meeting you all. Please take care and may all your flash dreams come true.

Thank you Jess for a great class!!!

I posted this earlier put i forgot the html part

It didn’t work. It’s a stillborn project. I call it a stillborn project because that term is more marketable than the truth, which is “Hi My Name Is Alan and I Am Very Stupid And Here is A Stupid Project That Stupidly Refuses to Work Because Actionscript and Bono and Also Alan are Very Stupid Stupidheads.”

HATE HATE HATE HATE HATE.

Rah.

So here it is! A new game for project 3 and 4!

enjoy

p.s. i couldn’t figure out how to do the score
