Just wanted to know if someone can explain the difference between these two conditionals:
if ( !object )
if ( object == null )
where object is an instance of a user-defined class.I'm sure that these two cannot be used in an interchangeable manner, or are they?
I've got a function which looks at movieclips (ball#_mc) which have been placed in a target zone (_ballPlaced[#] boolean). It then decides where to go on each movieclip timeline depending on which other balls have been placed in a target zone.Only the first condition is ever met, i.e. when all the balls are in a zone, they jump to their correct places in their timelines....however, it doesn't work for any of the other 'else if' conditions?
Here's my code...
// function to determine which video to play for each ballprivate function playVideo(event:Event):void { if (ball0_mc._ballPlaced[0] && ball1_mc._ballPlaced[1] && ball2_mc._ballPlaced[2] && ball3_mc._ballPlaced[3]) { ball0_mc.gotoAndPlay("BluYelRedGre");

Is there a better way to do use a use a boolean with visible? I'm setting up animations that have conditions for visibility, and I don't want to use something that performs poorly. This animation blinks 30 times and stops. It works without error, but takes a moment to load. I would like to learn other ways of using visibility with conditionals.
This is what I used 'waits before playing'
if(condition=5){
box.visible = !box.visible;
This works fine 'no pause'
if(condition<6){
box.visible = !box.visible;

I've got a function which uses a 'hitTestObject' test if two moive clips are touching each other. A FOR loop has been used to run through all the zones, to check if they've been touched. Within this FOR loop is an IF condition which then locks the ball to that particular zone if the ball and zone are touching. The ELSE statement sends the ball back to a random place on the stage if they're not touching.
However, the IF statement seems to be getting bypassed. Whenever a ball is dragged over a zone and the mouse is released, rather than locking to that zone's x and y positions, it gets placed randomly on the stage...i.e. the ELSE statement is being activated all the time?! I've commented out the ELSE condition and the IF works fine on it's own, it's just when the ELSE condition is included the IF is bypassed.
ActionScript Code:
private function zoneFill(event:MouseEvent):void{
for (var i:uint = 0; i<=8; i++){
var index:Number = event.target.name.substring(5,6);
if(event.target.hitTestObject(zone[i]) && zoneFull[i] == false && event.target._ballPlaced[index]== false){

I'm working with CS4 and AS3 using timeline coding. I have three sets of movie clips in three different arrays. The idea is to have topArray and downArray movies make zeroArray movies visible. For instance, if topArray[0] and downArray[0] are clicked, then r0_0 becomes visible. PROBLEM: r0_0 becomes visible when EITHER topArray or downArray is clicked. How to make r0_0 wait until BOTH top and downArray movies are clicked?

I have the following: ActionScript Code: if ((player.charVelocity < 9.0180945396304027e-26 && player.charVelocity > -9.0180945396304027e-26)) it seems to be firing as soon as charVelocity gets between 1 and -1.

View 5 RepliesI want to calculate the angle a line makes with the positive x-axis in a clockwise direction. It's a lot like a bearing except instead of North, I want the angle it makes with positive x-axis. The image illustrates what I'm after.
Below is the code I wrote to achieve this. It works fine but I am just wondering if there's a way to reduce all these if statements.

/**

i'm working on a homework assignment in where we created a match game. It's up to me to figure out how to tell the action script which difficulty the user play the game at. There are 3 buttons easy, mediym, hard. Each one lays out an increased number of cards say 4 for easy 8 for medium etc.
we are supposed to use the switch conditional to do this.My problem is how does the switch know which button was clicked?here is the code so far, it is only set up for the easy at the moment.It works fine until I tried to set up the switch.
package {
import flash.display.MovieClip;
import flash.display.Sprite;[code]....
when I click the easy button in the swf file I get this message.
ReferenceError: Error #1069: Property level not found on flash.display.SimpleButton and there is no default value.

View 3 RepliesEach line in the dynamic textbox has 15 characters, and yet you can notice the difference in the length(between each line).
I want to make the length of each line look same if they have same number of charaters.
Suppose I'm building a game where your ship moves with left/right keys.I assign a speed variable which is the number of pixels the ship will move when you press one of the said keys.Currently (on the tutorial I'm following) I have:
Quote:
static const speed:Number = 150.0
Can't I just replace it:
Quote: var speed:int = 150
Also, what's the difference between var a:Number and var a:int? And is there any important reason to add the .0 in 150.0?
I was just wondering what the difference between these two is.
