I've tried everything. Arrays are quite simple so I don't know why this doesn't function:
var menuList:Array = [menu_bag_mc,menu_chips_mc,menu_coke_mc,menu_cup_mc,menu_deodorant_mc,menu_fork_mc,menu_knife_mc,menu_lighter_mc,menu_milk_mc,menu_pill_mc,menu_rings_mc,menu_shampoo_mc,menu_spoon_mc,menu_straw_mc,menu_toothbrush_mc,menu_trashbag_mc,menu_water_mc];
function captureAllClicks(event:MouseEvent):void
{
trace(menuList.indexOf(event.target));
}
stage.addEventListener(MouseEvent.CLICK, captureAllClicks);
Every time I click on any of the items on the stage (which are all given the instance names listed above. each is a tweening movieclip containing a button) I get a trace of -1. WHY?!
edit2
What needs to happen:
for each (var mc:MovieClip in menuList) mc.addEventListener(MouseEvent.CLICK, createContent);
//right here, i need to make a variable that I can put in the "addchild" so that
//for every one of the list items clicked, it adds a movieclip child with
//the same name (such as menu_bag_mc from above) with "_frame" appended.
var framevar:MovieClip = menuList[i] += "_frame";
function createContent(event:MouseEvent):void {
if(MovieClip(root).currentFrame == 850) {
while(MovieClip(root).numChildren > 1)
{
MovieClip(root).removeChild(MovieClip(root).getChildAt(MovieClip(root).numChildren - 1));
}
MovieClip(root).addChild (framevar);
MovieClip(root).addChild (closeBtn);
}
else {
MovieClip(root).addChild (framevar);
MovieClip(root).addChild (closeBtn);
MovieClip(root).gotoAndPlay(806);
}
}
If I can't do a variable, there's no point for the whole "for each" statement you put together... not really any point for an array, because I'll still have to create 20 lines of code for each separate one. What's the point of having an array if you can't make variables from them?
because quite obviously event.target seems not to be in menuList.
the most likely explanation is, that your MovieClips have children, that are being clicked on and thus are event.target.
You should probably set mouseChildren to false on all those MovieClips. Or you could register individual handlers per movieclip as this:
function captureAllClicks(event:MouseEvent):void {
trace(menuList.indexOf(event.currentTarget));
}
for each (var mc:MovieClip in menuList) mc.addEventListener(MouseEvent.CLICK, captureAllClicks);

back2dos
why don't you try event.currentTarget instead of event.target
Also to help yourself trouble shoot, why don't you just trace the event.target and trace the event.currentTarget. You can also loop through your array and trace all the objects in it. Then get a better visual idea of what is going on.

I have created symbols which contain animations (mc1 - mc25). I would like to play these animations if I click on the symbols (click on mc1 -> play mc1, click on mc2 -> play mc2 etc.).
I created an array to address all my symbols in one go. It works ok.
var A:Array = [mc1, mc2, mc3, mc4,...mc25] // create array
car aClip:MovieClip;
for each (aClip in A) // stop all symbols
{aClip.stop();}
How can I get to the result below for all my symbols using an array function?
mc1.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_4);
function fl_MouseClickHandler_4(event:MouseEvent):void
{
mc1.play();
}
I tried something like this but I couldn't get it work:
aClip.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void {
aClip.play();
}
Thank you!
The simple way about it is to algorithmically figure which one was clicked. The script below is short and does not contain various checks, it assumes all the elements of A are really MovieClips.
// Assume, you filled the Array with these clips already.
var A:Array;
// Iterate all the clips.
for each (var aClip:MovieClip in A)
{
// Subscribe to each of the clips for the CLICK event.
aClip.addEventListener(MouseEvent.CLICK, clickPlay);
}
// Click event handler function. The point is, you can subscribe it
// to the multiple objects and use the function argument to figure out
// which one of them all is actually the source of the event.
// Furthermore, you can subscribe it to handle multiple events too,
// the argument also carries the id of the event. Sometimes it is
// really simpler to compose a single event-processing gate
// rather then process each one event in a separate handler.
function clickPlay(e:MouseEvent):void
{
// Use e.currentTarget because the initial e.target
// could be not the MovieClip itself, but some interactive
// element deep inside the MovieClip's hierarchy.
// Read about bubbling events (MouseEvent is bubbling)
// to get the whole picture of it.
// Typecasting, because e.target and e.currentTarget
// are of base Object type.
var aClip:MovieClip = e.currentTarget as MovieClip;
// Well, the only thing that is left.
aClip.play();
}
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.
I have an array with movieclips (r1, r2 etc) which are placed on stage dynamically every time there is a hittestobject. I want to add event listener to those movieclips in the array so that every time there is a click on them the last item to be removed. I have this code but it seems to be wrong because only the first element of the array is remove. Can you please help me?
var counter:int = 0;
function releaseToDrop(e:MouseEvent):void
{
Star(e.target).stopDrag();
if (Star(e.target).hitTestObject(target))
{
removeChild(Star(e.target));
var replace:Array = [r1,r2,r3,r4,r5,r6,r7,r8]
addChild(replace[counter]);
counter = counter+1;
}
else
{
trace("No collision.");
removeChild(Star(e.target));
}
}
replace[counter].addEventListener("click", bindClick(o));
function bindClick(o)
{
replace.splice(replace.indexOf(replace[counter]),1);
trace(counter);
}
For one, your bindClick function is inside the releaseToDrop function. This way that function will not be called. Also, try to use the static refence for the click event, so MouseEvent.Click instead of "click".
For your convenience, trace the current state of "counter" in the bindClick function, so you know what element will be removed. You will probably then find out where the flaw is in your logic.
A wise thing to to is also to check counter is not outside the scope of your array. So in bindClick, check for counter < replace.length. (for that the replace array of course has to be defined outside of the function scope of releaseToDrop.
Hope this gets you working in the right direction.
For future references adding addEventListener to the elements of an array so that every time there is a click on them the last item to be removed can be done by this code:
import flash.display.Sprite;
var replace:Array = [r1,r2,r3,r4,r5,r6,r7,r8]
var counter:int = 0;
// Every time there is a hittestobject an element of the array is placed on stage
function releaseToDrop(e:MouseEvent):void
{
Star(e.target).stopDrag();
if (Star(e.target).hitTestObject(target))
{
removeChild(Star(e.target));
addChild(replace[counter]);
counter = counter+1;
trace(counter);
}
}
// The first element of the array has an eventListener and when is clicked the last item of that array shown on stage is removed
var yourSprite:Sprite=new Sprite();
replace.push(yourSprite);
replace[0].addEventListener(MouseEvent.CLICK, myClickHandler, false, 0, true);
function myClickHandler (e:MouseEvent):void
{
counter =counter-1;
if (contains(replace[counter]))
removeChild(replace[counter]);
trace(counter);
}
Can you add an event listener to every movie clip that you spawn, then in each event handler, add a conditional to check if the clicked movie clip is the last item, then remove it (or do whatever you need to to it).
You should also accept Chicken's advice.
I'm creating an app with a search function. I display the images by loading from the array the one's which match the search criteria. All the images are loaded from the library. I want to be able to click on an image as though it were a button. Once I click I want to goto frame 3 and change a variable integer to say which image was clicked on so that I can display the information about the photo in frame 3. Can I do this using an event listener say
imagesArray[i].addEventListener(MouseEvent.CLICK, imageClick);
function imageClick(event:MouseEvent):void
{
gotoAndStop(3);
current = i;
}
or similar,
Thanks
Yes, but it won't be as easy. First, Bitmaps do not process events, so you can't assign a listener directly to a Bitmap object. Next, there is no "i" available in such a construction, you have to determine that "i" by yourself. To do that, you parse event.target property, which is the object that's been clicked. You wrap each Bitmap object into a separate Sprite object, assign listeners to these sprites, then you parse event.target to get the relevant object reference out of it, grab the index via indexOf() call, and assign it to global current variable.
for (i=0;i<imageArray.length;i++) {
var sp:Sprite=new Sprite();
sp.addChild(imageArray[i]);
// position "sp" correctly here
addChild(sp);
sp.addEventListener(MouseEvent.CLICK, imageClick);
}
function imageClick(e:Event):void {
var content=e.target.getChildAt(0); // the object that was wrapped
var i:int=imageArray.indexOf(content);
if (i==-1) return; // OW, out of array
current=i;
gotoAndStop(3);
}
I'm not so sure that setting "current" to "i" would work as the function wouldn't be running at the same time as the for loop.
I'm assuming that because you're using the [i] that you've added the event listeners in a for loop?
What you could do is:
for (var i:int = 0; i < (howeverManyTimesToRun); i++)
{
imagesArray[i].addEventListener(MouseEvent.CLICK, imageClick);
imagesArray[i].myIndex = i;
}
And then in your function (outside of the for loop)
function imageClick (e:MouseEvent) {
gotoAndStop(3);
current = e.currentTarget.myIndex;
}
Also in your for loop you might want to add
imagesArray[i].buttonMode = true;
To change the mouse cursor to a hand when their mouse goes over your image.
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
}
}
