I have an animation that may stop at 2 points depending on what the user fills in, if the animation stops at one of the two frames an objects has to apear and have to disappear if the user continues with playing the animation again. Can someone tell me how I can let object appear if the animation stops at a certain frame?
Do I need something like this? I have very little experience so please help!
star_mc._alpha = 0; star_mc.onEnterFrame = function(){ if(this._alpha < 100){ this._alpha = this._alpha + 5; }}
The code looks ok.... try it... just put it in the right place!
It's hard to tell where because I don't know how your animation built!!

So I have been working on my final project for the semester for my Computer Systems class, and we have been tasked to make a game using Flash and ActionScript 3.0. I've pretty much completed everything but I have come across an extremely strange occurrence of Flash CS6 being silly. I am moving a MovieClip up and down depending on a selected index, however, the image leaves 'residue of it's footprints' behind and also moves. I have tried hard to look for an answer as to why this is happening, but I don't know what it's called, or how to appropriately explain it - I'm coming from an area where one must program graphics, not just simply, drag and drop.
Below are pictures as to what I've come across, but first the code I'm using:
function updateThemeScreen():void {
button_selection.y += (selectedPositions[selectedTheme] - button_selection.y) / 2;
}
function attemptThemeChange(mxP:Number, myP:Number):void {
if(objectContains(theme_darkness, mxP, myP)) {
selectedTheme = 0;
} else if(objectContains(theme_halloween, mxP, myP)) {
selectedTheme = 1;
}
}
As you can see in the final image, it has copied half of itself and left it at the last button, which is strange, and shouldn't happen...
Link to the SWF zipped up with the required AS3 classes: Dude, RUN
So it seems that I have magically fixed this problem by hiding the buttons and showing them all in one frame. I don't know what this problem is or why it does it, but to fix it, you just need to hide and show the affected components - yes, in one frame:
function hideShow(object:MovieClip):void {
object.visible = false;
object.visible = true;
}
I have a scrollpane to which I add movieclips to. I am using it a an online users list. It works well so far but now I have run into a problem. I am able to remove the movieclips I want easily enough using removechild, but when I remove it there is only a blank space where the removed clip was. So I need to know how to have the scrollpane refresh somehow and move the clips below that one removed up. How can I do this?
I have tried invalidate, refreshPane, update, etc. Maybe I didnt have them in the correct order or something, but how can this be done?
If the answer is complex, could an example be provided please? Im really not good enough with as3 just yet to code an entire algorithm to get the number of children, remove them all, readding them, etc.
Any help please?
Just a variation, but saves the -1, simply rearrange such as:
lstOnline.removeChild(lstOnline.getChildByName("NAMEHERE"));
var numleft:Number = lstOnline.numChildren;
for(var i = 0; i < numleft - 1; i++) {
lstOnline.getChildAt(i).y = i*60;
}
Guess I was a little better than I thought. In case anyone else faces this problem, the solution I found was the following:
var numleft:Number = lstOnline.numChildren;
lstOnline.removeChild(lstOnline.getChildByName("NAMEHERE"));
for(var i = 0; i < numleft - 1; i++) {
lstOnline.getChildAt(i).y = i*60;
}
lstOnline is the name of the ScrollPane and in my case 60 is the height of the added movieclips.
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().
So im trying to make an easy script, which will hold a video...
And i will be able to drag the video around as i want, but the catch is... when it leaves borders of the frame, i want it to continue playing on the other side, even if its only half of the video or less...
I know how to transport it, to the other side, but not the half of it or less..
function everyFrame(event:Event):void {
if (movie.x + 100 < 1)
movie.x = 400;
}
Here is an image of the effect that im trying to achieve... http://i.imgur.com/w8E4s.png
Thank you in advance
Without seeing more code, I would say you need to set clipAndEnableScrolling.
clipAndEnableScrolling="true"
Try adding that to the group (Group, HGroup, or VGroup) that you have your video in.
Edit based on me understanding now...:
When the right edge of your movie touches the right edge of the screen, you will need to create a second movie and add it to the stage at a determined x of the first movie and y of first movie. I would say something like this...
onMoveOfFirstMovie():void
{
if(firstMovie.x + firstMovie.width > movieContainer.width)
{
if(secondMovie doesnt exist)
{
//create second movie if it isnt already on stage and set it's play position to the play position of first movie
}
secondMovie.y = firstMovie.y;
secondMovie.x = firstMovie.x + firstMovie.width - movieContainer.width;
}
}
Very rough code but it should be about right.
I'm wonderring if anyone can help me with making sure my... uhhh ... Z-index (bad pun, you'll see why in a moment) is in the wrong order. I've been doing this for a few hours straight now and my eyes are going buggy - but - maybe leaving a question on Stack overnight will help push this in the right direction.
I've been working on the code for https://github.com/AlexChesser/jsSprite and I'm as far as the 6th test. Use the W key to run, A and D to turn left and right: http://chesser.ca/jsSprite/06-brainnsss....php (Gettit? Z-Index?! Hilarious).
Anyways, You'll notice that if you run around the screen for a bit. the individual Zombies' white squares / dirty rectangles overlap the other zombies' squares. When working with multiple overlapping sprites, how does one go about making sure they all get drawn without upsetting any of the other sprites?
(You see z is for zombies, but z index like when you're dealing with overlapping in CSS - probably way funnier when you've been coding for a number of hours straight).
Thanks for your
Brainsss......
It's not a z-index issue, your zombies themselves are okay.
Your problem is really with the second line of drawFrame
drawFrame: function(){
Sprite.ctx.clearRect(0,0,Sprite.width,Sprite.height); //clear previous frame
// I am trouble:
MainContext.clearRect(Sprite.Xpos, Sprite.Ypos, Sprite.width, Sprite.height);
It is clearing a rectangle of the main canvas where the zombie once was every time you draw a zombie, which can affect nearby objects!
So instead you should be clearing the entire canvas each time.
Try commenting out the MainContext.clearRect in drawFrame, and instead add one in runloop like below. It should fix your problems.
runloop = function(m) {
// New clear put here!
MainContext.clearRect(0,0,canvas.width,canvas.height);
m.drawFrame();
for (Z in Zarr) { // For ZOMBIE in "Zombie Array" Aaaaarrrgghhh...
Zarr[Z].pointTo(m);
Zarr[Z].drawFrame();
MainContext.drawImage(Zarr[Z].canvas, Zarr[Z].Xpos, Zarr[Z].Ypos);
};
MainContext.drawImage(m.canvas, m.Xpos, m.Ypos);
};
How about sorting your array (Zarr) by the y coordinate Ypos of each zombie before rendering? Or are you getting at the problem with (a lack of) transparency?
