Is there any way by which I can make my button work, no matter in which scene or frame it is.
Is there any way by which i can call that Event Listener to another frame for that particular instance?
for example:
I have a button home_btn, I want this button to work in all scenes, without changing it's instance name. I already added an Event listener in first scene, but it doesn't work,
In another frame or scene.
Below is the code.
home_btn.addEventListener(MouseEvent.CLICK, process_it);
function process_it(event:MouseEvent):void
{
nextFrame();
}
I don't know how to use dispatch event function for my button.
// This only works for that particular frame.
Since you're doing this in the timeline, if you put the home_btn.addEventListener(MouseEvent.CLICK, process_it);
on the first frame of your main timeline, it will be registered even if you change to a different frame.
You can keep the function in its existing frame as that should still be called.
The reason why this works as opposed to the code being on a different frame is because frame 1 is where your timeline will start and process all the display items and code needed during this frame. That is any function, variable, or listener you want active will be running and/or stored into memory at the start of the application since it will always start on frame 1 until specified otherwise. If you have the listener on a different frame then you will have to gotoAndStop() to that frame to add the listener ( otherwise you are specifying that you don't want to add the listener until your application is at the frame ). Adding a listener to a display object on frame 1 is contingent upon the display object also being on that frame.

I'm using Flash CS6, AS3 to create buttons for my project. Below is my code:
Intro_btn.addEventListener(MouseEvent.MOUSE_DOWN, Intro_func);
function Intro_func(event:MouseEvent):void {
gotoAndStop("Intro");
}
No errors appear when I run it on the output and compiler panel, and the same happens when I run it through the debugger. Also, I have used the exact same code for five other buttons, and they have no problems working. Please can someone tell me what is wrong with my code???
I would need to know more info of your code and the type of buttons you're using, however I would try this steps:
1.- add a Button component from the component inspector, set its instance name, and add that same function to the Click event:
newButton.addEventListener(MouseEvent.CLICK, Intro_func);
function Intro_func(event:MouseEvent):void {
trace("function executed");
gotoAndStop("Intro");
}
2.- run your app and test if the action is executed with this new button. If this test pass, then your problem is your button.
check this on your button:
check the base class of the button (be sure its a MovieClip or a Button class)
check if your button is enabled/disabled.
check if your button or its children has mouseEnabled and mouseChildren set as
true.
check there is no other object on top of the button either in your artboard or added by code at runtime.
I finally would suggest you to set useHandCursor = true; this will replace your mouse pointer arrow to a hand when you move over your button (this is just to test that your button is actually interacting with mouse).
hope this helps.
sorry for the delay, But I've found your solution, It's easier than you thought: your frame is delayed.
your Intro_btn script is on frame 10, however in frame one you're telling it to go to frame 9 (the "Erhu" frame label) so the actions to setup the event listener are never being called.
Also keep in mind the following:
objects exists only in their frames life time, if you have an object from frame 5 to 10, it will only exist in there, so moving to a previous or later frame (e.g. frames 4 and 11) will internally delete the object in memory along with their asociated actions, in english:
you placed the button in frame 10 and added its MOUSE_DOWN listener however, if you go back to frame 0, since the button doesn't exists in this frame it will be deleted from memory along with its listeners, so if you go from frame 0 to any other frame different than 10, your button will never have its listeners associated.
So my suggestion:
1.- add your function into frame 0:
function Intro_func(event:MouseEvent):void {
trace("function executed");
gotoAndStop("Intro");
}
2.- create a new layer. In this layer add a keyframe at the same position where your Intro_btn is(frame 10), and fill the rest of the timeline of this layer with empty frames (no keyframes), finally in the same layer add in frame 10 your listener Intro_btn.addEventListener. this way, the action is available for every subsecuent frame from frame 10.
hope this solves your problem.
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 a Player movieclip object being placed on frames, where an example player is, then making the example player invisible. But when it runs the player is placed where the example is in the first frame, instead of in each current frame.
parent class:
playerStartX = exPlayer.x;
playerStartY = exPlayer.y;
Is there a way to either look only at the example in the current frame or else to remove only the example in the current frame after it has already been "copied"?
Not sure, if I understood your question completely, but maybe you should use an event handler for the Event.ENTER_FRAME event. This event is dispatched in sync with the frame rate of your SWF. Your handler could look like this:
function enterFrameHandler(event:Event):void
{
playerStartX = exPlayer.x;
playerStartY = exPlayer.y;
}
Because I don't no enough about how you structured/organized your MovieClips on the stage, I cannot say where to add the handler. But somewhere you have to do:
addEventListener(Event.ENTER_FRAME, enterFrameHandler);
I've got a timer event which seems to once in a while call itself before the ENTER_FRAME event handler which I made to force a Bitmap object to be top-most at all times by adding itself to the stage again.
The timer event fires every 50 milliseconds.
I tried setting the priority of the ENTER_FRAME event to 1, which reduced the ugly flickering, but did not remove it.
How can I force this Bitmap object to be top-most at literally all times with no flickering whatsoever?
Create two container MovieClips at the root of your application. Put all of your other display objects in the lower one and the Bitmap in the higher one. It saves you having to run a loop at all.
Alternatively, whenever you add something to the stage, instead of using addChild, use addChildAt(newChild,getChildIndex(bitmap)-1);
Hey guys I'm having such a hard time of it today.
I have a game, I've loaded into a parent SWF -
I would like my parent SWF to accept events I dispatch from within the game,
or have the ability to talk both ways.
--
Reason is, I would like to unload and load the game back in, once the end screen is active.
Any help and I'll give you beer.
thanks in advance.
Are the events dispatched by your game allowed to bubble up to your loader swf? The default value for the Event constructor sets this to false. If you were to set it to true, however, an event dispatched by a child swf would make it to its parent's listener.
For example: this.dispatchEvent(new Event("SOME_GAME_EVENT", true, true));
The first 'true' value says that the event should bubble up through the object hierarchy. The second says that the Event is cancelable. Once your loader swf has handled the Event, it is best to then call .stopPropagation() on the event so it does not further bubble unneccessarily.
can't you put in your parentSWF:
childSWF.addEventListener(MyCustomEvent.SOME_EVENT, listener) and just dispatch the events from the game?
As for talking the other way, it can call childSWF.someFunction() to call functions in the document class of childSWF, etc.
