Is it possible to change a frame label within a gotoAndStop('label') with the parameters in a function?
I'm playing around with updating code as I learn more and more techniques, and at the moment the code is a basic click-a-button to select the object shape, and on press the button disappears:
// Change the object into a circle.
circle_btn.addEventListener(MouseEvent.CLICK,function(){changeShape_fun(circle_btn,circle);});
// Change the object into a square.
square_btn.addEventListener(MouseEvent.CLICK,function(){changeShape_fun(square_btn,square);});
// Change the object into a star.
star_btn.addEventListener(MouseEvent.CLICK,function(){changeShape_fun(star_btn,star);});
function changeShape_fun(shape_btn,frame){
shape_btn.visible = false;
main_mc.gotoAndStop('frame');
}
However I can't/don't seem to know how to change a frame label through function parameters, or if what I'm trying to do is even possible.
Also to note, while I'm all ears for any more efficient ways of doing what I'm trying to do, I would still like to know how/if you can change frame labels through function parmeters.
Thanks! :)
You're very close, but you're trying to go to a frame called 'frame' and not the string contained within the frame variable. Try this instead:
// Change the object into a circle.
circle_btn.addEventListener(MouseEvent.CLICK,function(event:MouseEvent){changeShape_fun(circle_btn, 'circle');});
// Change the object into a square.
square_btn.addEventListener(MouseEvent.CLICK,function(event:MouseEvent){changeShape_fun(square_btn, 'square');});
// Change the object into a star.
star_btn.addEventListener(MouseEvent.CLICK,function(event:MouseEvent){changeShape_fun(star_btn, 'star');});
function changeShape_fun(shape_btn,frame){
shape_btn.visible = false;
main_mc.gotoAndStop(frame);
}
This will go to a frame within main_mc called 'circle' when you click the circle or 'square' if you click the square, etc.

I have been making a basic painting application similar to MS-Paint with basic paint, eraser and fill tools. It's this last one that's giving me some trouble.
I'm pretty new to using BitmapData but the idea is that when the user clicks the board, it triggers the startFloodFill method. This is shown below:
public static function startFloodFill(e:MouseEvent):void
{
trace("FLOODFILL");
var boardRef:MovieClip = e.currentTarget.parent.board; //Creates a reference to the board
var boardData:BitmapData = new BitmapData(boardRef.width, boardRef.height); //Creates a new BitmapData with the same size as boardRef
boardData.floodFill(e.localX, e.localY, 0x00CCCCCC); //Applies the FloodFill
boardData.draw(boardRef); //Saves the boardRef as bitmapData
boardRef.bitmapData = boardData; //Updates the board
boardRef.parent.addChild(boardRef);
}
Can anybody tell me what I've done wrong here? When I click, the board does not change. I expected the FloodFill to fill the entire bitmap with the chosen colour as the board is blank when I click.
I also tried replacing the last two lines with:
boardRef.addChild(new Bitmap(boardData) ); //Updates the board
Thanks
The problem is that you first use the floodFill, and then use the draw method, which actually fills the BitmapData with whatever param you give it - in your case it's the boardRef.
You should first draw the boardRef into the boardData, and then use floodFill. At the end, you need to create new Bitmap and display it.
Now you are setting the bitmapData of a MovieClip?! Don't know what you wanted, but you just need to add new child (new Bitmap)
Sorry for my complicated questioning ;)
I've created several components on my stage (Slider, TextLabel, CheckBox, ...) with the addChild(...) method. Now, if the user needs one Slider component more (for another input), I want to give him a button "addButton" (already on stage) with an CLICK addEventListener. The function which is fired in the addEventListener should create a new Slider component on stage, e.g.
addButton.addEventListener(MouseEvent.CLICK,addSlider("slid1",20,160,250,0,250,30));
The problem is to pass the parameters to the function, i need to set the new Slider to several basic values, like position, width, minimum, maximum and so on....
Can this be achieved in this way?
thx,
edwin
There are several ways you can do this. The simplest way is to call your function inside a mouse event handler:
addButton.addEventListener(MouseEvent.CLICK, addSliderHandler);
function addSliderHandler(e:MouseEvent):void {
{
addSlider("slid1",20,160,250,0,250,30);
}
EDIT (to answer your comment question):
To position your new component according to existing components, you can keep a variable reference to the position in the script and pass this as a parameter. For instance, suppose you want the first generated slider to be at y:160, and every slider to be 40px more than this, change the script to this:
var sliderY:int = 160;
addButton.addEventListener(MouseEvent.CLICK, addSliderHandler);
function addSliderHandler(e:MouseEvent):void {
{
addSlider("slid1",20,sliderY,250,0,250,30);//Pass sliderY instead of literal number
sliderY += 40;//Add 40 to sliderY
}
Now, every time you use this function to create a button it will be positioned at y = sliderY, then it will add 40 to sliderY....so the first one generated will be at 160, the next at 200, the next at 240 etc.
Hope this helps!
this is actually a noobish question, but is there a possible way to save a certain state of a movieclip?, example i dynamically added a movieclip called big_mc, then inside big_mc contains three(3) smaller movie called child_mc1 and child_mc2 and a close_big to remove big_mc from the stage, when i click either of child_mc1 and child_mc2, the child_mc will disappear prior to which child_mc i clicked.
so the scenario is when I click child_mc1 which remove itself from the scene, then next I'll click the close_big movieclip to remove big_mc from the stage and will save it's own state, so then the next time i run the SWF file and dynamically add big_mc to stage, child_mc1 would be still missing and child_mc2 would still be displayed (EVEN IF I CLOSE THE SWF FILE, the state should be saved). please help..much is appreciated.
code in main time line:
var big_mc:mother_mc = new mother_mc;
add_big_btn.addEventListener(MouseEvent.CLICK, call_big);
function call_big(e:MouseEvent):void
{
addChild(big_mc);
}
the code inside big_mc:
child_mc1.addEventListener(MouseEvent.CLICK, remove_child1);
child_mc2.addEventListener(MouseEvent.CLICK, remove_child2);
close_big.addEventListener(MouseEvent.CLICK, bye);
function remove_child1(e:MouseEvent):void
{
removeChild(child_mc1);
}
function remove_child2(e:MouseEvent):void
{
removeChild(child_mc2);
}
function bye(e:MouseEvent):void
{
this.parent.removeChild(this);
}
You want to start with SharedObject, which as Adobe puts it, "is used to read and store limited amounts of data on a user's computer or on a server". To save the "state" of the MovieClip is more complicated.
What about it do you want to save? The x property? Perhaps the alpha? EVERYTHING? Each object is stored in a default state in your swf. Library items in the Flash IDE are technically miniature classes, as evidenced by the way we instantiate them. Assuming you create something called customButton, you could spawn thousands of them onscreen (or one) like this:
var foo:customButton = new customButton();
Like a hand-written class, a copy of the customButton is created with all the properties you defined on it before you compiled it. If you want to change those properties, you have to address each and every one you want different.
Looking at this broadly, let's assuming you want to save the position of your button every time you load the swf. Load with getLocal(), and save with flush().
var settings:Object = SharedObject.getLocal("foo");
function updateState(e:Event):void {
myButton.x = settings.x;
myButton.y = settings.y;
}
function saveState():void {
settings.x = myButton.x;
settings.y = myButton.y;
settings.flush();
}
It's not impossible; there's simply no push-button solution for it. If you wanted, you could write a function which iterates over all DisplayObjects, and loads/saves each relavent property from/into your SharedObject. Might be overkill, though.
I hope to pop down a score panel when players win and pass the gate.
Normally it will pop down score board.
I think the best way is to use layer and pull down it.
But I only get the transition of scene, just wonder is there any way for layer transition?
Did not see an equivalent of CCTransitionScene :CCScene for CCLayer but layers can runActions using which we can bring out most of the animations/transitions.
Here is what I do in such situations but I guess you are thinking of the same thing. Nevertheless,
1.Create a layer and add it as a child at a position outside of your screen frame.
2.Then use CCMoveTo to move it to the desired location when you want to pull it down.
I have done something similar in the past.
Display your layer offscreen
i.e setposition(0, CCDirector::sharedDirector()->getWinSize().height*1.5f);
create an action to move it onscreen (I like to use CCEaseSineOut)
you can also use a callfunc to call a function when it has finished its animation
scoreLayer->runAction( CCSequence::create( CCEaseSineOut::create(CCMoveTo::create(1.0f, ccp(0, 0-_screenHeight*1.5f))), CCCallFunc::create(this, callfunc_selector(MainLayer::scorefinishedMove)), NULL));
Note: that function might need some fixes to ending brackets etc. And you may want to seperate out some of those actions rather than putting the initialization right in the runAction function
For layer transition you can do this:
CCScene* newScene = CCTransitionCrossFade::create(.5f,Layer2::scene());
CCDirector::sharedDirector()->pushScene(newScene);
In Layer2.cpp
CCScene* Layer2::scene()
{
CCScene* scene = CCScene::create();
CCLayer* layer = new Layer2();
scene->addChild(layer,1);
return scene;
}
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!
