There's a scene updating the game loop. And I made a shop scene.
Problem is previous scene update function is not called after shop scene is pushed.
I believe previous scene is not removed or deleted if new scene is added by pushScene method.
But why the update function is not called?
What's the best way to remain previous scene scheduler keep updating?
Thanks.
When you push a scene, that pushed scene is running and the previous scene is suspended. You can run whatever code you need in the update method of the pushed scene.
Or don't push a new scene but instead put that scene's content on a layer and animate (fade, move) it into view as needed. That way the main scene retains control.

My employer decided they wanted me to start doing animation with Adobe's new "Animate CC" application. My issue is that I don't know how to loop my animation outside of the Adobe Animate environment. I am new to Adobe Animate CC and ActionScript, unfortunately, so I will probably need a relatively basic answer to understand why my solution isn't working. From what I can tell, my ActionScript code is being ignored by the IDE completely.
In the IDE and in the browser test command, the animation plays beyond frame 100, to the end, and then flashes a frame of white before repeating. I need it to loop without this white frame interrupting the screen, whether that be through a loop or some other means that I'm just not aware of.
For context: my project has about 100 layers of content and I'm unfamiliar with how this program works. I've thoroughly searched the web for tutorials on how to do what I need to do, but I've come up empty handed.
I have an actions layer among my motion tweens and other layers

I've been trying to use gotoAndPlay(0) at frame 100 to start the animation over from the beginning.

Basically, how do I use Action-Script in Adobe Animate CC in order to infinitely loop my animation until closed?
Thanks everyone.
Your flicker may be a result of having an extra blank keyframe on one of your layers.
Assuming that you don't have any additional scripts to stop your animation (e.g. stop()), the Timeline should loop automatically whether your animation is inside a MovieClip or on the main Timeline. You shouldn't have to put any script on your timeline or in a separate AS file to make an animation loop. I would suggest this method.
Additionally, although you have the code specifying that you want it to go the first frame, it will ignore your call because the timeline is still playing and therefore the priority. One way you can combat this is by adding a stop(); function and a delay timer that contains your gotoAndPlay(0) function. This will take focus away from playing the Timeline and will allow you to execute your script. I wouldn't suggest this method because it seems a bit redundant.
However, if you're curious one way that you could approach this is shown below, simply add this script to the frame you want the animation to restart at.
//Stop the Timeline
stop();
//Create a delay timer for 5 miliseconds that is executed once
var timer:Timer = new Timer(5,1);
//Add an event listener that calls once the timer is complete
timer.addEventListener(TimerEvent.TIMER_COMPLETE, timerHandler);
//Start the timer
timer.start();
//Timer handler that is called once the delay timer is complete
function timerHandler(event:TimerEvent){
//Go to and play the first frame
gotoAndPlay(0);
}
I'm incredibly rusty at Flash having not touched it in probably 10 years and can't seem to figure this out, or find it online:
I have a MovieClip with two layers, each having a Shape Tween. Basically its a Door that opens and closes.
I dropped it onto the main timeline but now I need it to start and stop. This is where I'm now struggling since the last time I used Flash actions could go on specific keyframes.
I made a new layer called actions just to keep things organized and currently have:
barrier1.stop();
I just want something that lets me state a frame, say 57 to have barrier1 start playing on. Tried using play(); and Event.ENTER_FRAME with no luck. How would I set this up?
Well it is easy with the instance name of your movieClip
barrier1.stop(); // Stops the movieClip
barrier1.play(); // Resumes
barrier1.gotoAndStop(12) // Goes to 12nd frame and stop
barrier1.gotoAndPlay(12) // Goes to 12nd frame and play
barrier1.currentFrame // returns barrier currentframe
For capturing frame from scene level:
this.addEventListener(Event.ENTER_FRAME,onLoop);
function onLoop(event:Event){
if(barrier1.currentFrame == 57){
trace("BARRIER is in 57. frame");
}
}
Inside on the animation clip on the first frame
var root:MovieClip = this.parent as MovieClip
root.makeStartSceneAnimation()
**in timeline scene level [root]**
function makeStartSceneAnimation(){
/// barrier started to play
}
If you are using timeline, you can add Key frame on the desired frame, and then add stop(); as Action in the action layer. But bear in mind that if you do this in the main timeline - it will stop everything. If you want to stop that MovieClip, then you have to do this inside MoviceClip's timeline.
Okay so I have a movieclip called a_mc, if you click the movieclip, it goes to frame 5, and then on frame 5 there is a button called close_btn where if you click the button, it goes back to frame 1 and it is supposed to make a_mc invisible. Here is the actionscript code for frame 1.
stop();
a_mc.addEventListener(MouseClick.CLICK, aClicked);
function aClicked(event:MouseEvent):void {
gotoAndStop(5);
}
and on frame 5, the actionscript code is
stop();
close_btn.addEventListener(MouseEvent.CLICK, closeCLicked);
function closeClicked(event:MouseEvent):void {
gotoAndStop(1);
a_mc.visible = false;
a_mc.removeEventListener(MouseEvent.CLICK, aClicked);
}
see, the problem is, in frame 5, I make a_mc invisible and remove the event listener and go back to frame 1 and on frame one, it always executes the actionscript code so it again creates the event listener and makes a_mc visible. Any idea on how to stop this from happening?
I tried putting the code from frame 1 into a package and then a class and then a constructer method but it is saying
"Syntax error: package is unexpected"
Could you put all the code that you want to execute once in frame 1? - don't call stop() and let it run to the next frame.
Then put the rest of your code in other key frames and don't use gotoAndStop(1) so frame 1 is only called once?
You can try not removing the event listener on a_mc in frame 5, and then in frame 1 check if the event listener is already present (a_mc.hasEventListener()) as a signal that frame 1 has already been shown. Not exactly a 'bets practices' solution, but it might work.
Unfortunately, depending on the actual conents of those clip, and what happens in other frames, it may be the problem you're having is a consequence of the way movieclip object works in flash. When a frame is changed, flash instantiates new objects on the stage (added in new frame), and removes the ones not needed anymore (depending on the contents, but generally it's true). The 'a_mc' object that you manipulate in frame 5 may not be the same 'a_mc' object that is on the stage when you go back to frame 1. It may have been deleted and reinstantiated in the meantime.
To avoid things like that, it would be a better solution to have controlling code in a class outside of the timeline of the animating clip, or at least to keep the state in a separate object. I work in Flash Builder so I can't help you with the details of such organization in Flash Pro (which I presume you're using), but you could probably have all code on the frame 1 of the main clip, and then put the other movieclips with buttons and stuff as children of the main clip. That way main clip can control the state, and know what to show when.
I have an object with an instance name of arrow that moves across the page on a motion tweet when a button is pressed. When the button is released I want the arrow to move back to the start of the tween frame by frame.
I have set up an if statement when the button is released and its current frame is more than 1 to go back 1 frame.
So far the arrow is ignoring the if and stopping due to the else statement.
btn.addEventListener(MouseEvent.MOUSE_OUT, out);
function out(e:MouseEvent){
if(arrow.currentFrame > 1){
arrow.gotoAndStop(arrow.currentFrame - 1);
}else{
stop();
}
}
You would probably be better off making another tween on the timeline that goes backwards then just playing that. Another option is to use a third party tweening library like tweenlite since in there you can easily setup animations to run forward or in reverse.
Are you sure arrow is the name of the movie clip that you want to run the frames backwards on, or is that the instance of the element that changes over some other movie-clips timeline?
I am making a game in cocos2d. Game Scene has a menu button to take back to main menu which is a UIViewController. When user chooses to play again and same game scene is called to run in director, a pink screen appears on top of game scene.
It could be because of replacing the same scene with itself. So, I replaced it with an empty scene first when main menu is called. Code replacing scene is:
if ([[CCDirector sharedDirector] runningScene] == NULL) {
[[CCDirector sharedDirector] runWithScene: [MySceneLayer scene]];
}
else {
[[CCDirector sharedDirector] replaceScene:[MySceneLayer scene]];
}
It checks, if there is no scene running then starts the game scene first time. If some scene is already running, which in this case is an empty scene, then replaces it with game scene. The dealloc of game scene is also called which means that old scene is destroyed properly. Even then, replacing empty scene with game scene gives pink screen while replacing with any other new scene does not give any problem.
What can be the reason and what is the solution?
Finally, the problem caught and resolved. All it needs is careful play of adding and removing views. I was removing OpenGLView from superview when coming back to menu in UIViewController. While replacing the scene again, same
[[CCDirector sharedDirector] openGLView]
which was in use earlier, had to be added back to the application window. Right place and right timing did it.
Any minor error in views or sprites can show you with pink screen :)
