I have this interactive 5 seconds animated intro for a website. the preloader and one item are animating and i made the second animation follow the mouse cursor but it has to stay within a certain part of the stage to work with the other animation happening on screen.
I have this code on the movie clip
Mouse.hide();
potistiri.addEventListener(Event.ENTER_FRAME, newCursor);
function newCursor(event:Event): void { potistiri.x = mouseX;
potistiri.y = mouseY; }
and i like i said i just want it to stay in the area i want...
i found this code which gives me errors for not putting the staments if and else if correctly or that it needs a rightparen when i input my numbers in...
if(this._x>Stage.width){
this._x=Stage.width;
}else if(this._x<0){
this._x=0; }
but i cant get it to work...
i need it to move between x 208-656 and y 140-336 and when it gets out of that area the object stay there doing its loop and you see the normal mouse cursor moving in the rest of the screen.
thanks a lot in advance...im leaving my it to the experts in here to pls help me ouy!
The logic you're using in your if/else is fine for clamping the movie clip to a specific area, what exactly do your errors say?
In regards to seeing the normal mouse cursor again you could try using the same if/else checks to determine whether the mouse should or should not be hidden ie if the mouse is outside the area and is hidden, call Mouse.show(), else if it is inside the area and shown, call Mouse.hide().

I have two movieclips, one is on top, one is on bottom. The top one is set to the second frame. I move it to the z axis bottom on the next frame, and for the remaining frames it plays all frames like it has been reset without any code (like I didn't tell it gotoAndStop(2)).
Image example: http://i.imgur.com/mQ8f5uT.gif (hard to tell by the frame rate, but the dark green box starts playing as if I didn't set it's frame once I move it below)
I know it doesn't have that issue when I code the depth swapping with setChildIndex, but the animations are lost.
If you're wondering, it's a simplified issue of a larger moving character sprite animation that I would like to swap depths of movie clips in the animation without resetting the movie clips underneath the depth change. So I'm not really looking for a work around per se, unless there's a well design solution and not a band aid "hack."
I think I didn't understand your question fully. A MovieClip will keep playing or keep being stopped no matter what you do with it, even if it was removed from the scene. I made a simple example which shows that MovieClip state is not affected by depth change.
The working SWF is here to test: http://zdg.ru/tmp/updown.swf
And the code is:
import flash.events.MouseEvent;
var is_playing:Boolean = true;
btn_toggle.addEventListener(MouseEvent.CLICK, doToggle);
btn_updown.addEventListener(MouseEvent.CLICK, doUpdown);
function doToggle(evt:MouseEvent) {
if (is_playing) mv_test.stop(); else mv_test.play();
is_playing = !is_playing;
}
function doUpdown(evt:MouseEvent) {
var tmp:int = getChildIndex(mv_block);
setChildIndex(mv_block, getChildIndex(mv_test));
setChildIndex(mv_test, tmp);
}
I've a problem with ROLL_OVER event listener. When I enter the empty area withing the movieclip with mouse cursor, ROLL_OVER event triggers. But I want that event trigger only when mouse cursor is on the colored area.
To Make it more clear: Think about " O " letter, when mouse cursor is between the empty area of O letter (inside of O) , event shouldn't trigger. It should trigger only when mouse curser is on the black area.
How can I implement this?
Thanks

PROBLEM IS SOLVED THANKS TO #Ethan Kennerly
I just want to add a few things to help people have problem same as me. In my situation I tried to make continents glow when my mouse is over them. I used the ROLL_OVER/MOUSE_OVER eventlistener to check if my mouse is over them or not. But with the data given by Ethan Kennerly I produced another way.
In Ethan Kennerly's solution, if your mouse enters the area of continent from a transparent area , it doesn't get blur effect because ROLL_OVER and MOUSE_OVER event listeners only trigger once per enters so I used MOUSE_MOVE event listener on each continent movieclips.
And for this statement:
if (isPixelTransparent(DisplayObject(event.currentTarget), new Point(stage.mouseX, stage.mouseY)) {
return;
}
add whatever is in the "ROLL_OUT or MOUSE_OUT" eventlistener function, add all of them inside this statement. But don't remove ROLL_OUT or MOUSE_OUT functions.
It sounds like the movie clip contains a shape that has transparent pixels. Transparent pixels respond to mouse over and roll over. If you could draw vector graphics that have no shapes with transparent pixels, the mouse would ignore the empty space in the movie clip's bounding box.
Yet it sounds like you need to use transparent pixels and you want the mouse to ignore them, so you could guard, like this:
private function onRollOver(event:MouseEvent):void
{
if (isPixelTransparent(DisplayObject(event.currentTarget), new Point(stage.mouseX, stage.mouseY)) {
return;
}
// respond to roll over.
}
To detect transparency, Miguel Santirso rendered the pixels and translated the coordinate space here: http://sourcecookbook.com/en/recipes/97/check-if-a-pixel-is-transparent-in-a-displayobject (Except line 38 looks on my computer like "rect" got rendered as "ct"). You could optimize that code by only drawing the pixel in question, instead of the whole image, and checking if that pixel value (getPixel32) is 0, instead of calling a hitTest. I would optimize Miguel's code like this:
public static function isPixelTransparent(objectOnStage:DisplayObject, globalPoint:Point):Boolean
{
var local:Point = objectOnStage.globalToLocal(globalPoint);
var matrix:Matrix = new Matrix();
matrix.translate(-local.x, -local.y);
var data:BitmapData = new BitmapData(1, 1, true, 0x00000000);
data.draw(object, matrix);
return 0x00000000 == data.getPixel32(0, 0);
}
By the way, if all your movie clips would have the same hit test shape, you could create a separate transparent shape that listens to the roll over. I use a transparent shape to define a custom hit test shape that is a consistent and simple shape (like a circle) when the image is a more complicate shape (like an X or an O with nothing in the middle). The custom hit test shape is a Sprite with a transparent shape. The sprite listens to the roll over. A separate mouse listener shape is also useful if your movie clip, on later frames, creates new shapes that alter the silhouette of the movie clip.
The easiest solution would be using the Interactive PNG class by Moses.
http://blog.mosessupposes.com/?p=40
Normally the clear areas of a PNG are treated as solid, which can be especially frustrating when dealing with a lot of images that overlap each other because they tend to block mouse interactions on the clips below them.
This utility fixes that so that mouse events don't occur until you
bump against a solid pixel, or a pixel of any transparency value
besides totally clear. InteractivePNG lets you set an alphaTolerance
level to determine what transparency level will register as a hit.
I have a custom cursor in my flash project. That cursor consists of several parts (i.e. several movie clips inside of the cursor movie clip). And when the cursor rolls over different movie clips in my project, the parts of the cursor distort a little bit as though moving 1 pixel in relation to each other. And therefore the look of the whole cursor distorts a little. This happens every time the cursor crosses the boundary between the movie clips of the project (buttons, design pieces and so on). How can I make my cursor always retain one and the same look?
Thanks in advance
I'm guessing you're doing something like this to position your custom cursor:
stage.addEventListener(MouseEvent.MOUSE_MOVE, moved);
function moved(e:MouseEvent):void {
customCursor.x = e.stageX;
customCursor.y = e.stageY;
}
If so, when you move the mouse over a MovieClip or other element, your listener is receiving the event from that DisplayObject rather than the Stage. For some reason, DisplayObjects positioned at sub pixel values produce e.stageX and e.stageY values which aren't exactly the same as stage.mouseX and stage.mouseY, so your custom cursor elements are jumping slightly as the pixel values round differently.
Try using the Stage mouse position directly instead:
stage.addEventListener(MouseEvent.MOUSE_MOVE, moved);
function moved(e:MouseEvent):void {
customCursor.x = stage.mouseX;
customCursor.y = stage.mouseY;
}
I have created a map of Europe in Flash using AS3. I am an absolute beginner. Each country has been converted into a movie (using lasso tool). These movies are on one layer (with slight outline visible) on main timeline. On the other main timeline layer is the original outline map of Europe.
I have managed to make it so when a country is rolled over, a box tweens in scale to full size (to later insert text in).
I need to make it so that when each country is rolled over, that country's text box (which appears on Roll_Over) comes 'to the front'.
At the moment a couple of countries' text boxes work perfectly (ie: filled with white and completely visible), but most are either buried beneath the main map, or threading randomly through the faint movie clip outlines (which are at the front).
I'm guessing that this has to do with the display list. The countries that work perfectly are probably at the top. But how do I make it so that the country rolled over immediately goes to the top and returns on Roll_Out?
This would complete my map so any help would be VERY MUCH appreciated.
I have used following code:
//FRAME ONE
this.stop();
movieClip_6.addEventListener(MouseEvent.ROLL_OVER, fl_MouseOverHandler_15);
function fl_MouseOverHandler_15(event:MouseEvent):void
{
gotoAndPlay(2);
}
movieClip_6.addEventListener(MouseEvent.ROLL_OUT, fl_MouseOutHandler_67);
function fl_MouseOutHandler_67(event:MouseEvent):void
{
gotoAndStop(1);
}
//SECTION BELOW IS MY PROBLEM
movieclip_6.addEventListener(MouseEvent.ROLL_OVER,Rollover,false,0,true);
function Rollover(event:MouseEvent): void
{
setChildIndex(MovieClip(e.target),this.numChildren-1);
}
Many thanks in advance.
You can try calling addChild() again to the DisplayObject/Movieclip to bring it to the front. Instead of:
setChildIndex(MovieClip(e.target),this.numChildren-1);
Try going:
addChild(MovieClip(e.target));
You can use "layers" to bring objects in front of another.
constructor:
//Create the front layer
var frontLayer:Sprite = new Sprite();
//put all text boxes into front layer
frontLayer.addChild(textbox1); //etc...
//Add layer to mc
addChild(frontLayer);
rollover pops up:
textbox1.visible = true;
pop down:
textbox1.visible = false;
I have this code for my effect to zoom in and zoom out in certains buttons
canada.addEventListener(MouseEvent.MOUSE_OVER, canadaover);
function canadaover(event:MouseEvent):void
{
gotoAndPlay("canadaS");
trace("in");
}
canada.addEventListener(MouseEvent.MOUSE_OUT, canadaout);
function canadaout(event:MouseEvent):void
{
gotoAndPlay("canadaF");
trace("out");
}
canada.addEventListener(MouseEvent.CLICK, clickcanada);
function clickcanada(event:MouseEvent):void
{
trace("Mouse clicked");
}
the problem is when u reach certain corner of the button it kinda gets into a loop, any ideas how can i fix this?
here its the link of the swf i'm trying to do:
http://viajescupatitzio.com/america%20map.swf
If your buttons are MovieClips you can add inside a layer with a mask (for example rectangle) on top. Mask width and height should be your mouseover region and give it alpha = 0. It will be invisible, but it will work with MOUSE_OVER and MOUSE_OUT Events.
You should move your buttons into a different hierarchy level than the graphics you are changing - even if the buttons disappear, or are covered with graphics for just a very short moment, both mouseOver and mouseOut events will be fired (the mouse has left and reentered the button) - and that probably causes your "loop".
It is generally a good idea to have animations and graphical objects within nested MovieClips, and place control elements on a higher level of the display list - that way you can make sure the elements don't overlap and/or interfere.
