My flash game exists of a timeline with multiple frames (I know I should avoid the timeline)
The point of the game is a point and click adventure. The object that you are able to pick up get spawned and destroyed accordingly as you enter and leave the room. now my problem is when entering frame 14 (accessibel from frame 12) it creates a piece of paper which you are able to pick up if you have another item. Now my problem is when you can't or don't pick up the paper and go back to frame 12 (only exit is to frame 12), you can't click on any other object and you are basicly stuck on frame 12. When leaving and entering other rooms it works properly but for some reason it doesn't for on the paper on frame 14.
My code to remove objects works as following
In my Main.as Documentclass I have a function that called as soon as the game starts which does the following
if (lastframe == 14)
{
trace (prop.numChildren);
while (prop.numChildren )
{
prop.removeChildAt(0);
}
}
The lastframe variable is established when moving from frames
this function is found on the frame itself (each exit function on it's own respective frame)
function exitKantine(event:MouseEvent):void
{
Main.lastframe = 14;
gotoAndStop(12);
}
The function to remove the prop actually removes it but then causes all other clickable objects to be unusable.
Thanks for looking at my question and thanks in advance for your suggestions
I would say instead of removing children, add it once in the beginning, add all the listeners in the beginning, and toggle the visibility instead of trying to addChild and removeChild every time you want to hide it. Use an array so you can have a few happening at the same time.
something like this:
private function init():void
{
assignVars();
addListeners();
stage.addChild // make sure this is in document class or you are passing stage to the class using it
}
for (var i = 0; i < _thingsAry.length; i++)
{
if (_thingsAry[i] == 14)
{
_thingsAry[i].visible = false;
trace("the visibility of _thingsAry[" + i + "] is " + _thingsAry[i].visible
}
}

i am using AS3 to create a function that will automatically play a movieclip all the way through and then remove it. my project is going to have a lot of animated cutscenes, so id like to be able to call this function, use the cutscene id like as a parameter, and then move on to the next. the problem is, im trying to use the function multiple times in a row to play clips sequentially, but they're all playing at the same time. is there a fix, or a better way to do this altogether?
playClip(new a_walk); //find a way to make these stop playing at the same time
playClip(new a_door);
//a_walk and a_door are the AS linkage class names for the movieclips im referring to
function playClip (clip:MovieClip):void {
addChildAt(clip, 0);
clip.mask = myMask;
clip.x=412.4;
clip.y=244.5;
clip.addEventListener(Event.ENTER_FRAME, checkframes);
function checkframes(event:Event) {
if (clip.currentFrame == clip.totalFrames) {
//trace("wow! youre an idiot!");
if (clip.parent) {
clip.parent.removeChild(clip);
trace (100);
return;
}
}
}
}
Sounds like you want a mechanism to play a queue of MovieClips? If so, here is a way you can accomplish this:
//create an array with the clips you want to play (in order), in my example here, the items can be a MovieClip derived Class, or a MovieClip instance
var playQueue:Array = [a_walk, a_door];
//create a var to store the currently playing clip
var currentClip:MovieClip;
playNext(); //call this when you want the queue of clips to start playing
function playNext():void {
//if there was an item previously playing (currentClip has a value), stop it and remove it/dispose of it
if(currentClip){
currentClip.stop(); //stop it from playing
currentClip.addFrameScript(currentClip.totalFrames-1, null); //remove the frame script that was added
currentClip.parent.removeChild(currentClip); //remove it from the display
currentClip = null;
}
//check if there's anything left to play
if(playQueue.length < 1) return;
var nextItem:* = playQueue.shift(); //shift retrieves and removes the first item in the array;
if(nextItem is Class){
//if it's a class, instantiate it
currentClip = new nextItem();
}else{
currentClip = MovieClip(nextItem);
}
//initialize the movie clip
addChildAt(currentClip, 0);
currentClip.gotoAndPlay(1);
//this is just what you were doing before:
currentClip.mask = myMask;
currentClip.x=412.4;
currentClip.y=244.5;
//add a command on the last frame of the movie clip to play the next item in the queue
currentClip.addFrameScript(currentClip.totalFrames-1, playNext);
//addFrameScript is 0 based, so 0 would refer to the first frame. This is why we subtract 1 to get the last frame
}
I should note, that addFrameScript is an undocumented function. It serves as a nice shortcut so you don't have to have an ENTER_FRAME listener checking currentFrame vs. totalFrames. Being undocumented however, one can not count on it's continued existence in future versions of the Flash/AIR runtimes (though it's been around for a long long time)
note
This answer is a work in progress. I'm waiting on a response from the OP.
// playClip(new a_door); don't call this yet, or they will just both play.
var clipData:CustomClass = new CustomClass(); // add an instance of a custom class to hold the value of the movie
//clip being played (so that you can use this value later in the event handler.)
// it will also hold a value of the next clip
clipData._currentClip = a_walk;
clipData._nextClip = a_door;
playClip(new a_walk);
function playClip (clip:MovieClip):void {
addChildAt(clip, 0);
clip.mask = myMask;
clip.x=412.4;
clip.y=244.5;
clip.addEventListener(Event.ENTER_FRAME, checkframes);
}
function checkframes(event:Event) {
if (clipData._currentClip.currentFrame == clipData._currentClip.totalFrames) {
//trace("wow! youre an idiot!");
if (clipData._currentClip.parent) {
playClip(clipData._nextClip);
clipData._currentClip.parent.removeChild(clipData._currentClip);
clipData._currentClip = clipData._nextClip; // moves the clips down
//clipData._nextClip = here we have
//a problem. Do these clips play in a set
//order, first to last? Or do the play out of
//order jumping back and forth? If so, how
//are you planning on controlling which clip
//plays next?
trace (100);
return;
}
}
}
I haven't checked this in Flash yet to see if it works, but I noticed that you are defining a function inside another function, which I don't think is good practice, so this might clean things up for you. Give it a try and let us know.
I'll try to fix my code above when I get a chance. In the meantime, you answered my question about playing the clips in order, so a simple solution would be to put all the clips in an array and then play them by playClip(clipArray[i]) and then when the clip ends and gets removed, do i++ and call the same function playClip(clipArray[i]) which will play the next clip in the array.
Working a bit with AS3 and hit a wall on how to program through this situation. I have a class which represents a number say 103. I have a movieclip for each digit which I add to a holding movieclip and then add to the stage. I want to enable the ability to single click a digit like the zero in the number 103 and have it react since it is an individual movieclip and at the same time double click the entire number and have that react. Is there a way to cleanly do this wtihout confusing the code below is what I have thus far.
public function test()
{
numberimage = new MovieClip();
var images:Vector.<MovieClip> = generateNumericArray("");
for (var i:int = 0; i < String(value).length; i++) {
var temp:MovieClip = parsevalue(String(value).substr(i,1),images);
temp.x = i*50;
temp.addEventListener(MouseEvent.CLICK,click)
numberimage.addChild(temp);
}
numberimage.addEventListener(MouseEvent.MOUSE_DOWN,drag);
numberimage.addEventListener(MouseEvent.MOUSE_UP,drop);
numberimage.addEventListener(MouseEvent.MOUSE_OVER,doubleClick);
stage.addChild(numberimage);
}
any help on this would be much appreciated
Do, doubleclick on clip : stop listening to main movie, and listen now to sub clips. On click outside the main clip, listen back to the main movie and stop listening to its children.
Not sure if this is 100% what you are looking for: use the following, depending on what you are adding the listener to. You do have to enable double clicking first
numberimage.doubleClickEnabled = true;
numberimage.addEventListener(MouseEvent.DOUBLE_CLICK, click);
Ok, so I'm a beginner at AS3 and Flash and I managed to put this code together for an animation. A Button called start_btn is supposed to start and stop a movieclip called main_mc. On the first click of the Button, the Movieclip is supposed to play (which it does), however on the second click, the movie stops in the middle of its animation (which I don't want). My question is, when you click the Button a second time, how can i get the Movieclip to finish playing its animation then stop on the last frame?
I thought about using if (main_mc.currentFrame == main_mc.totalFrames); {main_mc.stop(); but the Movieclip still does not stop on the last frame. The Movieclip itself also has a gotoAndPlay(2); command on the last frame so that the animation repeats before the Button is clicked a second time.
here is the code i have:
`start_btn.addEventListener(MouseEvent.CLICK, mainaniS);
function mainaniS(event:MouseEvent):void
{
main_mc.play();
start_btn.removeEventListener(MouseEvent.CLICK, mainaniS);
start_btn.addEventListener(MouseEvent.CLICK, mainaniSt);
}
function mainaniSt(event:MouseEvent):void
{
if (main_mc.currentFrame == main_mc.totalFrames);
{main_mc.stop();}
start_btn.removeEventListener(MouseEvent.CLICK, mainaniSt);
start_btn.addEventListener(MouseEvent.CLICK, mainaniS);
}`
Try main_mc.gotoAndStop(main_mc.totalFrames).
I was going to provide a quick and dirty solution, but decided instead to try and explain a few of the issues with your current implementation and attempt to refactor and explain and better one. Unfortunately I don't have access to Flash right now, so the code is untested.
You're adding and removing event listeners often, which is generally a bad idea. Instead, since you're using a single button to perform multiple functions it would make sense to track the button state in a separate variable. In this case, a boolean for whether or not the movieclip is currently playing.
var playing:Boolean;
Now we can combine the mainaniS and mainaniSt into one and perform a different action based on whether or not the movieclip is playing, and just keep the one eventlistener on the button. I've also taken the liberty of naming the method something more meaningful:
start_btn.addEventListener(MouseEvent.CLICK, onStartClick);
function onStartClick(event:MouseEvent):void
{
if(playing) {
playing = false;
}
else {
playing = true;
main_mc.play();
}
}
You may be wondering why we don't call main_mc.stop() in the first block: the reason is that you don't want to stop the movieclip as soon as you click the button, but after the movieclip has finished playing if the button has been clicked. Therefore, we just set playing to false to indicate that we want it to stop later.
Finally, we need to make sure the movieclip stops upon completion, but only if playing is false. To do this we add a listener to movieclip that is called every frame, and checks whether playing is false, and if it's on the last frame. Note that the last frame is actually totalFrames - 1: this is because the frame numbers start from zero rather than one (i.e. if totalFrames is 3, the frame numbers will be 0, 1, 2).
main_mc.addEventListener(Event.ENTER_FRAME, animate);
function animate(event:Event):void {
if(!playing && main_mc.currentFrame == main_mc.totalFrames - 1) {
main_mc.stop();
}
}
All the refactored code together:
var playing:Boolean;
start_btn.addEventListener(MouseEvent.CLICK, onStartClick);
main_mc.addEventListener(Event.ENTER_FRAME, animate);
function onStartClick(event:MouseEvent):void
{
if(playing) {
playing = false;
}
else {
playing = true;
main_mc.play();
}
}
function animate(event:Event):void {
if(!playing && main_mc.currentFrame == main_mc.totalFrames - 1) {
main_mc.stop();
}
}
I have 5 layers with symbols on each: a, b, c, d and e.
I am trying to work out how to apply the action bellow to a, c, d and e when you hover over b.
Also is there another action similar to ' gotoAndStop(0); ' that instead of going immediately to frame 0 it goes back the way it came?
Link to .Fla http://www.fileden.com/files/2012/11/27/3370853/Untitled-2.fla
stop();
stage.addEventListener(MouseEvent.MOUSE_OVER, playMovie); function playMovie(event) { play(); }
stage.addEventListener(MouseEvent.MOUSE_OUT, stopMovie); function stopMovie(event) { gotoAndStop(0); }
stop();
Thanks
EDIT
After looking at your .fla, here is what is missing/misplaced:
Layers in flash don't mean anything other than z-order/depth. You cannot manipulate a layer in code. All your animations are on the same timeline, so they will always play together. If you want an individual item to animate without the others, you'll have to do the animation on it's own timeline (not just it's only layer). You access your symbols own timeline by double clicking it - do your animation in there.
To reference items that are on the stage, you need to give them an instance name. You do that by clicking on the item that's on the stage, then in properties panel, there is field where you can put in an instance name. For the code below to work, you'd need to give them an instance name of "a","b","c","d","e" respectively. This is different than the symbol name in your library (though it can be the same name).
One way you could do this:
var btns:Vector.<MovieClip> = new Vector.<MovieClip>(); //create an array of all your buttons
btns.push(a,b,c,d,e); //add your buttons to the array
for each(var btn:MovieClip in btns){
btn.addEventListener(MouseEvent.MOUSE_OVER, btnMouseOver); // listen for mouse over on each of the buttons
btn.addEventListener(MouseEvent.MOUSE_OUT, btnMouseOut);
}
function btnMouseOver(e:Event):void {
for each(var btn:MovieClip in btns){ //loop through all your buttons
if(btn != e.currentTarget){ //if the current one in the loop isn't the one that was clicked
btn.play();
try{
btn.removeEventListener(Event.ENTER_FRAME,moveBackwards); //this will stop the backwards animation if running. it's in a try block because it will error if not running
}catch(err:Error){};
}
}
}
function btnMouseOut(e:Event):void {
for each(var btn:MovieClip in btns){ //loop through all your buttons
if(btn != e.currentTarget){ //if the current one in the loop isn't the one that was clicked
goBackwards(btn);
}
}
}
There is no nice way to play a timeline backwards, but there are ways to do it. One such way:
//a function you can call and pass in the item/timeline you want played backwards
function goBackwards(item:MovieClip):void {
item.stop(); //make sure the item isn't playing before starting frame handler below
item.addEventListener(Event.ENTER_FRAME, moveBackwards); //add a frame handler that will run the moveBackwards function once every frame
}
//this function will move something one frame back everytime it's called
function moveBackwards(e:Event):void {
var m:MovieClip = e.currentTarget as MovieClip; //get the movie clip that fired the event
if(m.currentFrame > 1){ //check to see if it's already back to the start
m.prevFrame(); //if not move it one frame back
}else{
m.removeEventListener(Event.ENTER_FRAME,moveBackwards); //if it is (at the start), remove the enter frame listener so this function doesn't run anymore
}
}
It's been a while since I've had to write Actionscript that really needs to integrate with the timeline (in this case, controlling a series of frames that must happen in a certain sequence) and I am trying to figure out what to do.
In the first few frames, I have a button "next_1".
At frame 10, I need to have another button "next_2". I really really need this button to not be on frame one (I could possibly just make it invisible, but that's going to create a clickable area that I don't want).
The problem is, anything I don't put on "frame_1" renders as null in my Document class.
Is there any solution to this? I would rather not have to write my script on the timeline if possible (it seems easier in the long run to keep it in a document class)...
Items on the timeline are created on the fly, so if the playhead has not reached frame 10, next_2 is not created.
Easiest Document-class solution:
Create an array of frame labels like ["label1", "label2"]
Create sectionIndex var and set it to 0
Create a next button on its own layer so it is always showing.
When the next button is clicked, increment sectionIndex, then gotoAndPlay(myLabels[sectionIndex])
Okay, directly lifted from "Real World Flash Game Development":
/**************************************************
* FRAME LABELS *
**************************************************/
private function enumerateFrameLabels():void {
for each (var label:FrameLabel in currentLabels) {
addFrameScript(label.frame-1, dispatchFrameEvent);
}
}
private function dispatchFrameEvent():void {
dispatchEvent(new Event(currentLabel, true));
}
This dispatches an event at each frame label on the timeline.
Then you can just add event listeners for each frame:
addEventListener("name_of_my_framelabel", frameHandler);
addEventListener("another_framelabel", frameHandler);
And write a switch statement to add event listeners for the buttons when they actually show up on the timeline.
private function frameHandler(e:Event):void {
switch(e.type) {
case 'screen_2':
stop();
next_2.addEventListener(MouseEvent.CLICK, click2, false, 0, true)
break;
}
}
