ActionScript 3.0 :: New Tutorial On Enter Frame Event
Jun 1, 2008
I have added a new tutorial on the EnterFrame event in ActionScript 3. This tutorial is almost 40 minutes in length and goes into the syntax of using the EnterFrame event and as an added feature there is a discussion on adding filters to a Sprite in
ActionScript 3.
I have also completed the polling system on the website. There are now three active polls asking the users of the site for their opinions on the tutorials, the website itself and what they would like to see developed in the way of future tutorials. Users can vote more than once, but I am tracking the user IP so that when it comes time to slice the data I can gather accurate information. Just thought I would announce that up front.
The next group of tutorials under development will be the conditional statements used in ActionScript. The IF, ELSE IF and SWITCH statements. I am looking forward to those tutorials as we can now start making the tutorials much more interesting putting
all we have learned together.
what I'm trying to do: I have an animation thats 173 frames long - an intro to a html based website. This swf file is embedded in the index.html, and is to load my "main-html", when the animation is complete.To try and do this iv'e tried with the following code in a blank keyframe in my as3 code layer on the last frame of the animation: [code]Upon completed animation it just goes into a frantic loop which seems to be trying to connect to my "main.html", but never have a chance to completely connect before it tires again.I have used similar code for my buttons, inside the page itself, which works just fine.
the code below is placed on one frame of the main timeline...it works, but apparently continually triggers the "gotoAndPlay" action over and over again. How can an ENTER_FRAME event be made to play a moive clip such as "staged_kiss_mc" only once?
The playhead on the main timeline rests in this single frame for a while; it would be great if "staged_kiss_mc" were to only play once, when the playhead first enters this frame, rather than apparently repeating continually...is there code to stop this repetition?
i created couple instances of movieclip with some simple animation inside, want it to animate when mouse is over, and animate backwards when mouse is out.[code]it works better, only one instance move, but if i move mouse over second instance before first one finish moving back to the first frame (and remove listener), again both instances animate together, like they are using the same timeline.
I have two buttons and a light blue circle. When you press the second button from the left, it changes the variable name to "boxTwo".In the circle video clip I have a enterframe with a condition to say, if the name is "boxTwo" play an animation, but it doesn't work.
Button:
Code:
on(release){ var name = "boxTwo"; _root[name].gotoAndStop(12); trace(name); }
How do you stop an ENTER_FRAME event after two tweens have executed?I have an AS3 package-based-classes Flash website loading nicely. The very last effect is the hover or active state for the button for the current page to tell the user what page they're on. I want the button's active state to execute using an ENTER_FRAME event and NOT using a Timer method. Mainly because I'd simply like to know how it's done and also because I've already used several timers to load the API. But, using the code below, I can't stop the ENTER_FRAME precisely after two tweens have fired - the Alpha tween and the Tweener that pulls the a blur effect into focus.[code]
I've tried several IF and ELSE IF conditions to tell Home.removeEventListener(Event. ENTER_ FRAME, OverState); exactly when to occur but the IF conditions either removeEventListener too soon, before the two tweens have fired, or the IF conditions just don't execute at all and the ENTER_FRAME trace continues on ad infinitum. You can use IF conditions that precisely operate on stage X and Y positions. But I can't figure out how to make an IF condition execute precisely after the two Tweens.How do you stop an ENTER_FRAME event PRECISELY after two tweens have executed so that Home.removeEventListener( Event.ENTER_ FRAME,OverState); executes at exactly the right point?
I frequently see the usage of ENTER_FRAME and EXIT_FRAME event types in AS3 code. I can even use the first event type just blindly to get certain things done. But I want to clear my concepts on these very fundamental things. My qeries are as below:When do the above 2 event types take place - I mean what triggers them?Does ENTER_FRAME trigger at the rate of FPS? If a MovieClip spans over 48 frames and the FPS = 24 - does this mean the ENTER_FRAME will occur 48 times for the full life-span of the MovieClip?Regarding the EXIT_FRAME, I could not find any example or description yet.
I have a UILoader on the main timeline, then I have to load an external mc with a ENTER_FRAME event in it. When I load something else, I found the ENTER_FRAME event is still working. Why doesn't it unload with the mc?
I'm having trouble getting the Video class to work.. Everything works fine until I try to add an on enter frame event listener to the movie. I basically want to overlay an effect that gets updated every frame but adding the event listener causes the movie to freeze before it loads or on the first frame or just shortly after starting play back.. Check out the source code at [URL]
It freezes even if the enter frame method body is commented out so I don't think it's because of extra overhead..
I have a series of MCs in my root timeline. On each frame in the root, I am simply running 'stop();' to allow the MC within the frame to play through all the way. Once the timeline within the MC reaches the last frame, I have the following AS to go back to the root and play the next frame (each frame is labelled):
If I have an input text field on frame 1 and I enter text in it then I have a button that say sends me to frame 2. On frame 2 I have a button which sends me back to frame 1. Why when I got back to frame 1 is my text not shown?Why does an input text field go blank when leaving the frame? How can I make it so when i enter text on frame 1 and then go to frame 2 and then back to frame 1 the text i entered is still there?
I have a button on the stage called enterCostBtn that when it is pressed it executes the code inside the calculateCost function. What I want to do is to be able to use the ENTER key on my keyboard to trigger that function. In other words I would like to be able to use the ENTER key or click directly on the enterCostBtn to trigger this function.
Code: enterCostBtn.addEventListener(MouseEvent.CLICK,calculateCost,false,0,true); function calculateCost(event:MouseEvent):void { var material:Number=Number(Material_txt.text); var labor:Number=Number(Labor_txt.text);
i'm just trying to do something really basic and I'm stumped.all i want to do is create a radom number onEnterFrameits to go at the end of a game i've made and the score will be radom at the end screenso far I have this below but it will not stop it just keeps going and going i've put stop(); in but that does not seem to work. I know its simple but I just can't see it.
So I've about hundred of map tiles and each title has some object which does some stuff. And one of things it should do is to update text (a time after which you need to do something) in text field. How should i do it better - with enter frame event and on each enter frame update it or set up a timer object which on each second would update the text in text field?
I have external swfs that loads in a container on a main swf. When I press a button on the main swf, I would like to load a specific frame from an external swf.Here is what I have so far:
I am trying to play a simple movie clip when the playhead gets to a frame label called "home". The moveclip is called "playRollClick". I am trying to write this in as3.
The code below is what I've come up with so far, but it doesn't seem to work.
addEventListener(Event.ENTER_FRAME,playRollClick); function playRollClick(event:Event) { rollClick_mc.play(); }

I want AS to create a new meteor once the old one enters the atmosphere...If I just tell it to run the function once it is in the atmosphere, it will infinitely create meteors and subsequently crash Flash.[code]
I just started using AS3 and I wanted to make a simple script. Basically what I have is a speech bubble with text in it, and every time the player clicks on the screen, the bubble will move horizontally onto the screen. The problem is that after the 4th or 5th time clicking, the bubble will stop entering from the right, but the text will still change. Here is my script so far:
[code]....
What I noticed was that as the clicks increased, the speech bubble's x position was shifted to the left more and more each time. I don't get it, since I set the x position to 800 each time the function is run.
