Arrow Keys Code by Jovan Game Studios

[The FlashMaster]

Hello.
Today I will show and explain the arrow keys code. This code can help you if you want to make game with moving object with the arrow keys.


First you go to Insert>Symbol. Now you draw your object. Then you go to Scence 1.

On the Action Script box of your object you write this code:

onClipEvent (enterFrame) {
if (Key.isDown(Key.UP)) {
this._y -= 5;
}
if (Key.isDown(Key.DOWN)) {
this._y += 5;
}
if (Key.isDown(Key.RIGHT)) {
this._x += 5;
}
if (Key.isDown(Key.LEFT)) {
this._x -= 5;
}
}

So let's explain this code.
With the "if" function you make condition when some arrow key will be pressed. When you press arrow key the object is moving with adding or subtracting the scaleY (up and down) or scaleX (left and right). That the code.

Thank you!

When you press arrow key the object is moving with adding or subtracting the scaleY (up and down) or scaleX (left and right).

You're adding or subtracting 5 to the x and y coordiantes (_x and _y properties). scaleX and scaleY have nothing to do with it (just a typo perhaps?)

Here it is in AS3

import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, moveIt)
function moveIt(evt:KeyboardEvent):void{
    if (evt.keyCode == 37){
        myMC.x -=5;
    }
    if (evt.keyCode == 39){
        myMC.x +=5;
    }
    if (evt.keyCode == 38){
        myMC.y -=5;
    }
    if (evt.keyCode == 40){
        myMC.y +=5;
    }
} 

The differences here are

1. This function only fires when a key is down, saving processing speed.
2. Any key on the keyboard can be added in this function.

Definitely agree with rynoe, Flashmaster's energy should be directed at teaching newbies how to use Google, or for that matter the seach feature of this forum.
