So i'm trying to make an capture alien game where you will need to use your arrow keys to control a cage to capture the alien. Here is my uncompleted codes
import flash.events.Event;
stop();
lunar_txt.text="Please capture the alien using Up,Down,Left,Right arrow keys!";
var capture:Boolean=false;
var randomX:Number = Math.random() * stage.stageWidth
var randomY:Number = Math.random() * stage.stageHeight
/*alien_mc.addEventListener(Event.ENTER_FRAME, checkcapture)
function checkcapture(event:Event):void
{
while(capture==false)
{
alien_mc.x= randomX;
alien_mc.y= randomY;
}
}
*/
alien_mc.x= randomX;
alien_mc.y= randomY;
var upPressed:Boolean = false;
var downPressed:Boolean = false;
var leftPressed:Boolean = false;
var rightPressed:Boolean = false;
stage.addEventListener(Event.ENTER_FRAME, keydirection);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keycontrols);
stage.addEventListener(KeyboardEvent.KEY_UP, keyboard);
function keydirection(event:Event)
{
if (upPressed)
{
cage_mc.y -= 10;
}
if (downPressed)
{
cage_mc.y += 10;
}
if (leftPressed)
{
cage_mc.x -= 10;
}
if (rightPressed)
{
cage_mc.x += 10;
}
}
function keycontrols(event:KeyboardEvent):void
{
switch (event.keyCode)
{
case Keyboard.UP:
{
upPressed = true;
break;
}
case Keyboard.DOWN:
{
downPressed = true;
break;
}
case Keyboard.LEFT:
{
leftPressed = true;
break;
}
case Keyboard.RIGHT:
{
rightPressed = true;
break;
}
}
}
function keyboard(event:KeyboardEvent):void
{
switch (event.keyCode)
{
case Keyboard.UP:
{
upPressed = false;
break;
}
case Keyboard.DOWN:
{
downPressed = false;
break;
}
case Keyboard.LEFT:
{
leftPressed = false;
break;
}
case Keyboard.RIGHT:
{
rightPressed = false;
break;
}
}
}
alien_mc.addEventListener(Event.ENTER_FRAME, checkinstage)
function checkinstage(event:Event):void
{
if(alien_mc.y > stage.stageHeight)
{
alien_mc.y= randomY;
alien_mc.x= randomX;
}
else if(alien_mc.x > stage.stageWidth)
{
alien_mc.x= randomX;
alien_mc.y= randomY;
}
}
Using while loop for looping the alien to random co-ordinates when it isn't captured gives me this error
"Error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds.
at MainTimeline/checkcapture()"
On the other hand, using do while loop completely crashes my program.
So which loop should i be using in my case? & is my codes wrong? Also, how do i add a delay to the loop? Let's say i want it to change alien position every 2 seconds?
2nd question, is there something wrong with my function checkinstage codes? After adding those codes my alien is still appearing out of the stage
