Creating the battery 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. (we will choose 8 levels in this example)
    • Level: In the first frame, create a level bar corresponding to the lowest level.
      In last frame create a keyframe and stretch your level bar to the highest level.
      Then add a motion tween.
    • Background: You can add a layer to put all your static components.
    • Your timeline will be like this: Timeline battery.jpg
  • In the first keyframe of the ActionScript layer add this code:
batMax = fscommand2("GetMaxBatteryLevel");
batLevel = fscommand2("GetBatteryLevel");
batSource = fscommand2("GetPowerSource");
batLevel2 = Math.ceil(batLevel*levelsNumber/batMax);
if (batSource == 0) { //If charger is not plugged
/* If charger is plugged, it will go to nextframe,
so the battery indicator will be animated.*/
  • In all other keyframes add this code:
  • Put this movie clip into your scene.

Adding a percentage indicator

If you want to add a text indicator:

  • Create a new layer and add a dynamic text.
  • Fill the var field to link it to a variable (assuming batText in this example)
  • Add this code in the first keyframe of the ActionScript layer, just before the if statement:
batText = "Battery Level: " add math.ceil(batLevel*100/batMax) add "%";

Flash Lite 2.x recommended improvements

  • {{Icode|call(1): This action was deprecated in favor of the function statement.
  • [...]Level: " add Math.c[...]: Macromedia recommends that you use the + operator.
