I'm trying to set a button to invisible in AS3 however when the I leave the frame and come back to it the button is visible again. This is for a jeopardy game I make making for comm tech class.
Here is what I currently have:
a1.addEventListener(MouseEvent.CLICK, a1mouseClick);
function a1mouseClick(mouse:MouseEvent) {
a1.visible = false;
gotoAndStop("A1");
trace("Going to A1");
}
however when it comes back to the frame with the a1 button it is visible again.
Here is my current animation: https://dl.dropbox.com/u/23938245/jeporady.fla
While moving through the timeline flash player can recreates sprites, movie clips and text fields, so your buttons appears visible again. To prevent recreation move all controls to separate level without key frames. If key frames are required try to set the same instance name for this button in all keyframes.
#fsbmain and #prototypical they are right.

I was looking at your project, and offer a quick fix, you need to do the following:
Create a new layer on top to manage a few of actions availables for all frames with the following actions:
import flash.display.DisplayObject;
// Manages the buttons visible state
var buttonsStates:Object = {
"a1":true, "b1":true, "c1":true, "d1":true, "e1":true,
"a2":true, "b2":true, "c2":true, "d2":true, "e2":true,
"a3":true, "b3":true, "c3":true, "d3":true, "e3":true,
"a4":true, "b4":true, "c4":true, "d4":true, "e4":true,
"a5":true, "b5":true, "c5":true, "d5":true, "e5":true
};
// Checks the buttons visibility
function checkVisibility () {
for (var buttonName:String in buttonsStates)
{
var child:DisplayObject = this.getChildByName(buttonName);
child.visible = buttonsStates[buttonName];
}
}
// Saves the visible satatus to false
function setVisibilityToFalse(target:*) {
buttonsStates[target.name] = false;
target.visible = false;
}
Every time you want to check the visibility of the buttons you must call the checkVisibility() function. For example, every time you return to the button list.
Finally the event handler for each button must be like this:
function a1mouseClick(mouse:MouseEvent) {
setVisibilityToFalse(mouse.currentTarget); // Saves the visible state to false
gotoAndStop("A1");
trace("Going to A1");
}

You are missing a fundamental aspect of how the flash timeline and keyframes function. Once you move away from that frame, the stage instance of the content of that frame and it's properties/states are gone. When you return to that frame, the instance is created again based on the keyframe contents.
I think the best solution given your current approach is to put the main board persistent throughout all the frames. You can do that by creating a layer for it, and have it's keyframe extend from frame 2 to frame 27. However, your next issue will be adjusting visibility of all the elements on that screen when you don't want them visible.
My suggestion would be to put all the elements of that screen into a movieclip symbol of it's own and add that movieclip, and all code for it's listeners, to this new layer you created. For example you might name that instance - main_board and therefore you could modify it's visibility with main_board.visible property. If you did choose that solution, you would need to modify all the code on that frame to use that instance name as well ie :
main_board.a1.visible = false;
Also, you'd need to modify all you addEventListener lines as well :
main_board.a1.addEventListener(MouseEvent.CLICK, a1mouseClick);
Your approach for this game could be greatly simplified, but even further beyond the scope of this question than I have already gone!

Everything I've found is for making a separate button, but I'm trying to make it so that clicking on the movieclip itself makes it change size. The reason is that it's being animated moving across the page, so clicking it is the challenge. Can anyone help? This is the code I tried:
info_btn_mc.buttonMode = true;
info_btn_mc.addEventListener(MouseEvent.CLICK, openInfo);
stop();
function openInfo(e:MouseEvent):void {
enemy_first.play("shrink");
}
You cannot use play("shrink"), the method
play() (Moves the playhead in the timeline of the movie clip) has no arguments. use gotoAndPlay/gotoAndStop instead that received an argument called frame:Object (frame number or label (String).
enemy_first.addEventListener(MouseEvent.CLICK, openInfo);
enemy_first.stop();
function openInfo(event:MouseEvent):void
{
trace('event.currentTarget:', event.currentTarget);
event.currentTarget.gotoAndPlay("shrink");
}
I wrote a simple game and I want to add custom mouse cursor. I created MovieClip called Pointer, exported it to AS3 and wrote this code:
/* Custom Mouse Cursor
Replaces the default mouse cursor with the specified symbol instance.
*/
stage.addChild(movieClip_2);
movieClip_2.mouseEnabled = false;
movieClip_2.addEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor_3);
function fl_CustomMouseCursor_3(event:Event)
{
movieClip_2.x = stage.mouseX;
movieClip_2.y = stage.mouseY;
}
Mouse.hide();
//To restore the default mouse pointer, uncomment the following lines:
//movieClip_2.removeEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor_3);
//stage.removeChild(movieClip_2);
//Mouse.show();
Here is a screenshot:
Whenever I play the game (ctrl enter) it stops the play and duplicates the custom cursor. Is there anyway I can make it not duplicate this is very annoying and I have no idea on how to fix it.
~ EDIT 2 ~
Okay I changed the code to but the problem is now it's showing me the regular cursor and the custom one at the same time.
movieClip_1.mouseEnabled = false; movieClip_1.addEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor); function fl_CustomMouseCursor(event:Event) { movieClip_1.x = stage.mouseX; movieClip_1.y = stage.mouseY; } stage.removeChild(movieClip_1) Mouse.hide()
~ EDIT 3 ~
Thank you #LDMS for helping me. I had to remove the first line stage.addChild(movieClip_1); and it worked. :)
Most likely, your problem stems from this line:
stage.addChild(movieClip_2);
When you add a movie clip that was created on the timeline to another display object (like the stage), it will not get removed from that new display object except through code.
If your timeline loops, then every loop it will create a new movie clip and add it to the stage (but not remove the old one).
To fix it, do one of the following:
don't loop your timeline (so the code only happens once), eg put a stop() on your timeline
manually remove the movie clip from the stage before the timeline loops (eg stage.removeChild(movieclip_2) at the end of your timeline
Don't add it to the stage to begin with. (just take out the stage.addChild(movieClip_2); line)
I got a simple flash scene that contain movie clip that contain sliding button that changing every few seconds:
every layer contain a button and another movie clip.
If I want to add event-listener to a simple button on stage, i just write:
f4.addEventListener(MouseEvent.CLICK, f4Click);
function f4Click(event:MouseEvent):void
{
flash.external.ExternalInterface.call("dlHTCMD", "switchtogame?code=fnf50");
}
but when I'm trying to access the button inside the two movie clips, like
optContainer.optBeach.btnBeach.addEventListener(MouseEvent.CLICK, btnBeachClick);
and I'm adding a trace function to see if the event are triggered but nothing is happening.
looks like a simple problem but i didn't find a solution.
I thought about extending the button class and add a bind function with the value as the name of the button and set the Event Listener but I'm not an AS3 expert :(
Thanks.
Try this:
// Pass mouse events to children
optContainer.mouseChildren = true;
optContainer.optBeach.mouseChildren = true;
// Reset hit area
optContainer.hitArea = null;
optContainer.optBeach.hitArea = null;
// Reset masks
optContainer.mask= null;
optContainer.optBeach.mask= null;
Also check whether on each key frame button have name.
I have a movieclip with several layers and frames. Some of those contain buttons. When I click button 1 I want it to go to the next frame. When I click button 2 I want it to go to frame 23. This is the code I'm using for button 1:
this.addEventListener(MouseEvent.CLICK, convnext);
function convnext(evt:MouseEvent):void
{
MovieClip(parent).gesprekkencivcen.nextFrame();
}
and this is the code for button 2:
this.addEventListener(MouseEvent.CLICK, convend1);
function convend1(evt:MouseEvent):void
{
MovieClip(parent).gesprekkencivcen.gotoAndStop(23);
}
What happens now is that when I click either of the buttons, or in fact anywhere inside the movieclip (even layers I haven't applied actions to) it executes both functions at the same time so I end up going to frame 24. Can somebody provide an answer to this problem?
Obviously this in both cases refers to the same object, and not to the buttons in particular. Record the names of those buttons as you've named their instances on the timeline, say button1 and button2 and write the code employing those names.
button1.addEventListener(MouseEvent.CLICK, convnext);
function convnext(evt:MouseEvent):void
{
parent.parent.gesprekkencivcen.nextFrame();
}
button2.addEventListener(MouseEvent.CLICK, convend1);
function convend1(evt:MouseEvent):void
{
parent.parent.gesprekkencivcen.gotoAndStop(23);
}
With this, however, you will need to update the link to gesprekkencivcen in both listeners, as those buttons will have this as parent, and their target apparently is not a child of this. I have tried to plainly set a call to parent.parent.gesprekkencivcen, which might not work.
I'm completely new to Flash and AS3, and I'd have thought this would be a simple question, but I've been unable to find an answer online or in the documentation. I'm trying to use addEventListener (Event.ENTER_FRAME) and (.currentFrame) to disable a button for part of an animation sequence. While the animation sequence fades in, the Button Hand cursor is visible and people can select it before the sequence is completed. I want this button disabled for the first 213frames of the main timeline, which is when the button becomes visible.
Earlier, I was successfully able to disable a Rewind button for parts of a different movie scene using the code below with a few insignificant things changed.
Skip_btn.addEventListener(MouseEvent.CLICK, SkipToGoToScene);
function SkipToGoToScene(event:MouseEvent):void
{
MovieClip(this.root).gotoAndPlay(1, "Opening");
}
//Skip_btn functions
Skip_btn.addEventListener(Event.ENTER_FRAME, skipDisable);
function skipDisable(event:Event) {
if (this.currentFrame < 213)
{ Skip_btn.mouseEnabled = false;
} else {
Skip_btn.mouseEnabled = true;
}
if (this.currentFrame > 213) {
Skip_btn.removeEventListener(Event.ENTER_FRAME, skipDisable);
}
}
The problem is that before I could just use "this.currentFrame" as the button was on the same timeline that it controlled, whereas now it's embedded in a MovieClip that is on the main timeline. What can I swap "this" for so I can reference this main timeline? Also, could someone fill me in on what the other "identifiers" are for ".currentFrame", as I'm not too sure how it works. The documentation examples ask for Movieclips such as "MyMovie_mc.currentFrame", but what if you just want to reference a main timeline?
If the button is on main timeline you could just use
this.root.getChildByName("Skip_btn").mouseEnabled = true;
And if you start playing animation on main timeline use
MovieClip(this.root).currentFrame
