Movie Clips frozen but swf has not crashed - AS3 CS6 - actionscript-3

I'm making a top down shooter for a college project. I'm getting extremely low on available time left to complete this.
I followed a tutorial as we was not taught any AS3 although expected to creating a game in this language so there is commented code due to this. The tutorial lead me up to creating a player on the stage that moves by keyboard presses and can fire bullets by pressing the left mouse button, but it didn't help with creating enemies at all.
So I created an enemy movie clip that just spawns on the stage at X=0 and Y=0 (random spawning will be added later), and it's supposed to move towards the players location but it doesn't. When the swf loads up it appears they have started to move but have frozen on the screen. It's not crashed because I can still move the player around and fire bullets? Any help is appreciated.
Main.as code
Enemy.as code

Well, you are not calling the moveTowards() in any loop -> the position is not updated. Or where exactly are you updating the enemy's position? I see only one setting of .x, .y of enemy and it is right after you create the object, no further updates.
Put this into your loop function in Main.as:
for(var i:int=0; i<enemies.length; i++) {
Enemy(enemies[i]).moveTowards(player.x, player.y);
}

Actionscript-3 looping issue--Adobe Animate CC

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
https://gyazo.com/6e0b8502d98b6c9903bb96ac3a939bae
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);
}

Flash AS3 | Looping sound for each animation set

with University done I've finally had time to go back to practicing my Flash work, and I need some help with getting sound to loop and change depending on what part of the animation is playing.
This is also partly a follow up question to an older one I asked, so look here to get more detail as to where I'm coming from if you don't understand! (I've solved that issue, the current one relates to following up on it!)
Flash AS3 | Finishing current animation set before code is executed
The situation is basic: I have two different scenes, one of a man walking and one of a man running. It loops seamlessly of the man walking until you hit a button, where it finishes the animation then starts looping the run animation. Likewise, hitting the button again, finishes the loop before going back to the looping walk animation. The code for the button is below.
import flash.events.MouseEvent;
Next2.addEventListener(MouseEvent.CLICK, Change_2);
function Change_2(event: MouseEvent): void
{
addEventListener(Event.ENTER_FRAME, enterFrame);
function enterFrame(e:Event):void {
if (currentFrame == 30) {
gotoAndPlay(31);
removeEventListener(Event.ENTER_FRAME, enterFrame);
}
}
}
My issue is trying to get a footstep sound to match up with these animations. So while the man is walking, the 'walking footsteps' sound clip will play and loop alongside the animation, and when the button is pushed and the animation moves into the running animation, the 'running footsteps'' sound will play.
Any help on this would be much appreciated. I'm terrible when it comes to anything audio/code based.
Well u can check about soundChannel. soundChannel can stop() and play() ur audio.
So import ur external sound or use internal one. ur code probably seems like this.
var mySound:Sound = new Sound(new URLRequest("YourSoundPath"));
var sc:SoundChannel = new SoundChannel();
//when u wanna play
sc = mySound.play();
//when u wanna stop
sc = mySound.stop();
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/SoundChannel.html
also look this link for more info
If you want to really MATCH the footsteps to the animation (for example, the step sound should play when the player have put his feet down) the only sure way to do that is to place the sound on a different layer where your animation is and set the sound to play as "stream" (if i remember correctly).
Otherwise the animation might be out of sync because of different computer capabilities, current computer or graphics card load etc.
When the sound is set to play as "stream" the flash player is orienting on the sound and drop frames if the graphics are slow to keep the sound and animation in sync

How to make a movieclip play on a specific frame in AS3?

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.

Move enemies in platform game

Im relative new to as3, this is my first question here.
Im making super mario game, I added tiles, collision detection, enemies, scrolling.
Sorry for my english, if you dont understand me well, I uploaded file here that you can understand better.
http://www.fastswf.com/K0pTu_0
When game starts all enemies are moving, what I want is that enemies move only if they are on the stage, or if they are near the player.
For example if I set enemy position enemy.x = 3000;
I dont want that he moves if player.x = 40 or something like that.
I tried something like this
if (enemy.x < stage.stageWidth)
{
enemy.x += enemy.speed;
}
But when enemy left the stage, he just stop and wont move anymore.
Btw, I crated one movie clip and I put everything inside it including player.
For example I scroll MovieClip to left, and character go right.
You may want to consider a pre-made platform. This has a free version that you can use to help develop something similar to what you are working on. The paid version has some nice features as well.

Clip staying on screen while not in timeline anymore

I have a particular problem : I have a fla with 2 frames, with a clip of instance name "my_clip" on frame 1 and no clip en frame 2. If i move by code (like a tween) "my_clip", when I go to frame 2, the clip is still on screen, whereas frame 2 is totally empty in my fla.
How flash work at this level ? Does he stop "syncronizing" a clip with the fla once the clip has been moved by code ? How can I check at frame 2 that the scene should be empty ?
(I'm with flash cs 5.5 and player 11)
Actually what FLASH does when we are trying to change the depth or start drag and some more dynamic functionality it freezes the target movieclip in stage. Eventually there is only one stage in FLASH and guess what if the movieclip has been frozen in the stage? It is visible or available always.
So in your case the same has happened. The clip has just frozen to the stage. Needless to say, the second frame is empty always. You don't need to check the second frame. What all you need to do is remove that clip before you navigates to either next frame or scene.
#LondonDrugs_MediaServices : I can't post my code and fla because there is too much code unrelated to the problem.
But as I was trying to make a little fla to reproduce my problem and show it to you, I figure out that the problem was not where I thought it was : I fact it was because each time I start dragging my clip i was doing a setChildIndex on it to put it on top. And it was precisely the setChildIndex wich would cut the "syncronization" between the clip and the fla timeline.
Thanks anyway for your answers, it kind of help me in a way :)
