i have a movieClip, which has 3 frames. when i call mc.init(); the mc movieClip should check with the current language and go to the specific frame.
E.g. current lang is 'tw', the trace correctly returns 2. However, the on screen display is the content of frame 1. and i can still trace a movieClip inside frame 1.
Can anyone tell me the reason of the issue??
mc (movieClip)
function changeLanguage(){
if (currentLang =='en'){
gotoAndStop(1);
}else if (currentLang=='tw'){
gotoAndStop(2);
}else if (currentLang=='fr'){
gotoAndStop(3);
}
trace(this.currentFrame);
}
function init(){
changeLanguage();
}
main.as
mc.init();

i found that it can gotoAndStop(3) without any problem, only when from frame2 to frame1 has the problem.

Sorry this is so specific but I have combed through so many pages and videos and tutorials and can't figure this out.
I have all of my animations within a MovieClip. In the movie clip is also a stage sized white square button with the instance name "btn". Back on the main stage I have a second layer called "actions" with the following code applied to the first (and only) frame. It's not working. At all. (HUGE) tia
stop(); // this will stop the movie from playing at the start
btn.addEventListener((MouseEvent.ROLL_OVER, playMovie);
btn.addEventListener((MouseEvent.ROLL_OUT, stopMovie);
function playMovie(evt:MouseEvent):void {
play();
}
function stopMovie(evt:MouseEvent):void {
stop();
}
The problem is when you say play(); or stop(); which object are you really commanding? Your playMovie function could be in theory used to control many MovieClips at once, in different ways, so be specific with your commands...
btn.play(); //start the playback of "btn" MC
btn.stop(); //stop the playback of "btn" MC
Also consider using MOUSE_OVER/OUT instead ROLL_OVER/OUT etc but whatever works for you.
For reversing you will use btn.prevFrame(); together with an ENTER_FRAME event function. This function reads your Document settings for the FPS. For example, if you set 30 frames-per-sec then whatever instructions you put inside the event function will be processed 30 times per second.
See this other Answer for advice about reversing the playback of a MovieClip.
#VC.One is correct in how you should implement a solve to your issue, however in response to your comment on their answer, I thought I would demonstrate how to implement this fully for you - incase they don't.
var removeUpdate = false;
btn.addEventListener(MouseEvent.MOUSE_OVER, playMovie);
btn.addEventListener(MouseEvent.MOUSE_OUT, stopMovie);
function playMovie(evt:MouseEvent):void {
// Stop rewinding the movie clip and play it
if(removeUpdate){
stage.removeEventListener(Event.ENTER_FRAME, update);
removeUpdate = false;
}
// play our button
btn.play();
}
function stopMovie(evt:MouseEvent):void {
// stop our button
btn.stop();
// ... and rewind it
stage.addEventListener(Event.ENTER_FRAME, update);
removeUpdate = true;
}
function update(evt: Event){
// moves the button movie clip backwards one frame.
btn.prevFrame();
// If we have finished rewinding the movie clip, then stop
if(btn.currentFrame == 1){
stage.removeEventListener(Event.ENTER_FRAME, update);
removeUpdate = false;
}
}
It is important that you remove the update event because if you don't, the movie will never play again, because it will go one frame forward and then back again every frame due to; btn.play(); btn.prevFrame();
I have a combobox on the stage and changing its value I want to play only a certain range of frames:
stop();
combo01.addEventListener(Event.CHANGE, change);
function change(event:Event):void{
if (combo01.selectedItem.label == "BAL"){
gotoAndPlay(50);
if (currentFrame == 99) {stop();}
}
}
The game is not stopped but returned to frame 1.
You want your current frame check to happen when frame 99 is reached, not when change() is called. One way you can do this is to add a listener to check each frame as it is entered by the timeline until it reaches your desired frame:
addEventListener(Event.ENTER_FRAME, checkFrame);
function checkFrame(e:Event):void {
if(currentFrame == 99){
stop();
removeEventListener(Event.ENTER_FRAME, checkFrame);
}
}
Another way is to use the undocumented (but long supported) addFrameScript(): actionscript3 whats the point of addFrameScript
You could also just put a conditional stop() on frame 99, such as if (stopFrame == 99) stop(), then simply set stopFrame in your change handler.
You get the idea. You need your check to happen at frame 99.
I'm trying to make a reversed play module in Action Script 3. I have a video, 200 frames long that I imported to Flash as a movie clip. I name the movie clip and inserted some key frames to make the video stop at specific frames, making it a 3 stage animation.
Whenever I swipe/pan to the right (detecting a positive x offset) it gives the command play();, the movie clip will play til it finds a stop.
What I want to achieve is to play it backwards from the current frame til the previous stop when I swipe to the left (detecting a negative offset).
I sorted out the swipe/touch programming and what I'm missing is the backwards bit. I've managed to make it work, going backwards 1 single frame, not the whole bunch that exist prior to hit the previous stop frame. My code for the swipe and play forward is this, with the single prev frame included, which gives me just one frame back instead of the whole set before the previous stop.
Multitouch.inputMode = MultitouchInputMode.GESTURE;
mymovieclip.stop();
mymovieclip.addEventListener(TransformGestureEvent.GESTURE_SWIPE , onSwipe);
function onSwipe (e:TransformGestureEvent):void{
if (e.offsetX == 1) {
//User swiped right
mymovieclip.play();
}
if (e.offsetX == -1) {
//User swiped left
mymovieclip.prevFrame();
}
}
You could try this:
import flash.events.Event;
import flash.display.MovieClip;
//note that this is not hoisted, it must appear before the call
MovieClip.prototype.playBackward = function():void {
if(this.currentFrame > 1) {
this.prevFrame();
this.addEventListener(Event.ENTER_FRAME, playBackwardHandler);
}
}
function playBackwardHandler(e:Event):void {
var mc:MovieClip = e.currentTarget as MovieClip;
if(mc.currentFrame > 1 && (!mc.currentFrameLabel || mc.currentFrameLabel.indexOf("stopFrame") == -1)) { //check whether the clip reached its beginning or the playhead is at a frame with a label that contains the string 'stopFrame'
mc.prevFrame();
}
else {
mc.removeEventListener(Event.ENTER_FRAME, playBackwardHandler);
}
}
var clip:MovieClip = backMc; //some clip on the stage
clip.gotoAndStop(100); //send it to frame 100
clip.playBackward(); //play it backwards
Now you can put 'stopFrame' label to the clip's timeline (stopFrame1, stopFrame2... stopFrameWhatever) and the clip should stop there until playBackward is called again. Note that you should remove the enter frame event listener if the clip hasn't reached a stopFrame or its beginning and you want to call play/stop from the MovieClip API, otherwise it may cause problems.
So I have two movieclips, sRP_mc and dP_mc, on the first frame. Now, when either of the movieclips are clicked on, then I want the movieclip to be removed from the stage and then I want the frame to change (I want the movie to go to frame 5). On frame 5, there is a close button, which, if clicked, takes you back to frame 1 (but when it takes you back to frame 1, I want the movieclip which was clicked on to not be there anymore). Here is my code for my first frame (frame 1).
import flash.events.MouseEvent;
stop();
if (sRP_mc.visible == true) {
sRP_mc.addEventListener(MouseEvent.CLICK, sRPClicked);
function sRPClicked(event:MouseEvent):void {
sRP_mc.removeEventListener(MouseEvent.CLICK, sRPClicked);
removeChild(sRP_mc);
gotoAndPlay(5);
}
}
if (dP_mc.visible == true) {
dP_mc.addEventListener(MouseEvent.CLICK, dPClicked);
function dPClicked(event:MouseEvent):void {
dP_mc.removeEventListener(MouseEvent.CLICK, dPClicked);
removeChild(dP_mc);
gotoAndPlay(10);
}
}
and on frame 5, there is a close button and the code is this.
import flash.events.MouseEvent;
stop();
close_btn.addEventListener(MouseEvent.CLICK, closeScreen);
function closeScreen(event:MouseEvent):void {
gotoAndStop(1);
}
and on frame 10 there is also a close button the code is this.
import flash.events.MouseEvent;
stop();
close_btn.addEventListener(MouseEvent.CLICK, closeScreen2);
function closeScreen2(event:MouseEvent):void {
gotoAndStop(1);
}
As you can see, if sRP_mc or dP_mc are removed using the removeChild method, then sRP_mc and dP_mc should not be visible (.visible != true) but when I play this, it says that sRP_mc and dP_mc are always visible and the child does not get removed completely from the stage (or I think the isntance keeps coming back whenever I go back to frame 1). Why is it doing this and how would I fix it?
When the object is removed from the stage the visible property isn't changed to false unless you do so manually. Here's a better to way to check if an item isn't on the stage (I also cleaned up your inline function):
if (sRP_mc.stage != null) {
sRP_mc.addEventListener(MouseEvent.CLICK, sRPClicked);
}
function sRPClicked(event:MouseEvent):void {
sRP_mc.removeEventListener(MouseEvent.CLICK, sRPClicked);
removeChild(sRP_mc);
gotoAndPlay(5);
}
If an object is removed from the stage its stage property is set to null. Hopefully this helps!
I want to ask about this problem. I have a movieclip (instance name : char). Inside it I have 2 frames. The first frame contains a movieclip (it does nothing I forgot why I even bother to make it into movieclip). This first frame has frame label "still".
The second frame also contains a movieclip, inside it contains 12 frame. This second first frame has frame label "run"
This is my code
char.gotoAndStop(char.still);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keysDown);
stage.addEventListener(KeyboardEvent.KEY_UP,keysUp);
function keysDown(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT)
{
char.gotoAndStop("run");
this. char.scaleX = 1;
}
}
function keysUp(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT)
{
char.gotoAndStop("still");
}
}
The problem is, when I press RIGHT ARROW button, It moves, but the movieclip (with frame name "run") can't loop or even play complete from frame 1-12, it only plays from frame 1-9 then stop (not go to frame 10 or even loop)
is there something wrong with my code?
Have a look at how often the KEY_DOWN-Event is actually fired. For example by just tracing.
function keysDown(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT)
{
trace("pressed");
char.gotoAndStop("run");
this. char.scaleX = 1;
}
}
You will realize that the event is thrown WHILE the Key is pressed, not only once. You actually call the gotoAndStop("run") repeatedly, which makes your animation mc restart all the time.
