Compatibility: Flash Lite: 1.1, 2.x

Creating the signal indicator

• Create a new movie clip
• In this movie clip create at least 2 layers:
  • ActionScript: In this layer create as many keyframes as levels you want to display plus one. (we will choose 8 levels in this example, so 9 frames to create)
  • Level:
    • In the first frame, create a level bar corresponding to the lowest level.
    • In the last but one frame create a keyframe and stretch your level bar to the highest level. Then add a motion tween.
    • In the last frame draw an indicator corresponding to the "no network" state.
  • Background: You can add a layer to put all your static components.
  • Your timeline will be like this:

• In the first keyframe of the ActionScript layer add this code:

levelsNumber=8;
signalMax = fscommand2("GetMaxSignalLevel");
signalLevel = Math.ceil(fscommand2("GetSignalLevel")*levelsNumber/signalMax);
networkstatus = fscommand2("GetNetworkStatus"); 
 
if (networkstatus == 0) { //If there is no network
	signalLevel = levelsNumber + 1;
}
 
gotoAndPlay(signalLevel);

• In all other keyframes add this code:

call(1);

• Put this movie clip into your scene.

Flash Lite 2.x recommended improvements

• call(1): This action was deprecated in favor of the function statement.
