How to Control Volume Using the Arrow Keys

Fig. 09: Example of using arrow keys to control volume

If you wanted to control the volume with the right and left arrow keys, the following modifications to the above code could be made.

this.onEnterFrame = function () {
if (myLoopVolume<99) {
fadeIn01=1
}
if (myLoopVolume>1) {
fadeOut01=1
}
//Increase Volume with Right Arrow Key
if ( Key.isDown(Key.RIGHT) && fadeIn01 != 0) {
_root.myLoop.setVolume(myLoopVolume);
myLoopVolume=myLoopVolume+5;
if (myLoopVolume>99) {
fadeIn01=0
}
}
//Decrease Volume with Left Arrow Key
if (Key.isDown(Key.LEFT) && fadeOut01 != 0) {
_root.myLoop.setVolume(myLoopVolume);
myLoopVolume=myLoopVolume-5;
if (myLoopVolume<1) {
fadeOut01=0;
}
}
}

The Flash example in Fig. 09 also allows for the use of the Up and Down keys to control volume.

The flash's horizontal road drive was done in CS4 and was upgraded to CS6. The car responds to right/ left key and flash will auto-generate the movement of roads from left-right or right-left based on random number. Have fun driving in this virtual environment and avoid other cars... :) If you are creative, a road driving game can be created from it.
