Today, when I was packing for my old files, I suddenly found out a flash game that was implemented by me 8 years ago. I was using Flash 4 at that time and the coding is really horrible.
It’s a memorable application and I got you here for the complete rewritten version. The original Flash 4 source is also included inside the zip file.
For your reference, Stray Sheep is my favorite Japanese cartoon character when I was young. I hope you will love it as well.
Comparison
Flash implementation: 40 minutes (Implemented First)
Silverlight implementation: 80 minutes
What’s the difference?
- Keyboard Event: KeyboardEvent [AS3] vs KeyEventArgs [C#]
Source codes
Stray Sheep [Flash 9, AS3] (42.7 KiB, 1,302 hits)
- Stray Sheep [Silverlight 2, C#] (38.4 KiB, 1,495 hits)
Flash
Silverlight
KeyboardEvent [AS3] vs KeyEventArgs [C#]
Adding keyboard event is very easy in AS3. However, it will become very complicated when many keys are pressed at the same time. If you are game developer, I think you probably understand what I mean.
// AS3
stage.addEventListener(KeyboardEvent.KEY_DOWN, on_key_down);
private function on_key_down(e : KeyboardEvent):void{
switch(e.keyCode){
case Keyboard.LEFT:
// do something after pressing left arrow
break;
case 70:
// do something after pressing the "f" key
break;
}
}
The code is similar in C#. The main difference is that the keyboard event seems work only for the RootVisaul Control. I will try to figure it out later on.
// C#
this.KeyDown += new KeyEventHandler(Page_KeyDown);
void Page_KeyDown(object sender, KeyEventArgs e)
{
switch (e.Key)
{
case Key.Left:
// do something after pressing left arrow
break;
case Key.F:
// do something after pressing the "f" key
break;
}
}

This method of reading keyboard input is not useful for games though.
Right now you’re just reacting on the keyDown event, which is fired by your keyboard.
When the user holds down a key, you’re receive 1 keypress, a small delay and then the same keypresses repeatedly.
the duration of the delay, and the speed of the repeated keypresses is user defineable on their own computer.
In games you should (in flash) put your keyboard reading function in your main game loop, so it gets called every frame, and instead of waiting for key events, just check which keys have been pressed using (for example) Key.isDown(Key.RIGHT)
This also enables you to read out more than 1 key at a time.
there should be something like that in silverlight too, but i’m not sure.

Time is money as the old saying goes, and by studying this put up, I spotted that I saved myself a number of valuable time, which might have been otherwise spent on reading low consistency information throughout the almighty web. Thanks for the straight to the purpose, priceless input!
