Storing Data Similar to Cookies

Description: Store data with flash so that data remains after closing an applet.

Flash uses Shared Objects to allow data to be stored even after a user closes a flash applet. This is very similar to a browser's use of cookies. Main code in the applet:

//Select the local shared object
var so:SharedObject = SharedObject.getLocal("setbgcolor");
//check if the bgcolor has been previously set
if(so.data.bgcolor!=undefined){
  //if set, set the background color to that color
  setcolor(so.data.bgcolor);
}
//set the background color and save it.
function setcolor(color){
  var bgcolor = new Color(bg);
  bgcolor.setRGB(color);
  so.data.bgcolor=color;
  //force the file to be written
  so.flush();
}

Each button in the applet calls the following code in the on(press) function: setcolor(0x00FF00); 0x00FF00 is a hexadecimal number, and you can tell that because hexadecimal numbers begin with 0x in flash. To delete a set variable in this applet use either delete so.data.bgcolor; or so.clear();

Hey Stefan,
You could use an if statement to see if the music has been set to on or off, or if it is not set.

How do you make a object create from another object, and make a enemy that disappears after hit by another object?
