ActionScript 2.0 :: Changing The Alpha Of A M.c. With A Slider?
Jun 21, 2005
I have been checking out the following tutorial:on how to adjust the volume with a slider.it's great!what I'd like to do is use that same slider to adjust the alphaof a movie clip.is that possible?or maybe adjust the alpha of a symbol.what i'm trying to do is create "mood lighting"where the user can move a slider and lighten or darken an interiorspace, by adjusting the alpha of a dark square on top of the scene.

have trouble with the Alpha slider (Color Effect>Alpha) not going all the way to 0% or 100%? A lot of the time, I can only get up to 99% or down to 1%, even if I manually enter values into the textbox accompanying the slider. Some of the time, it will not even take a manual entry in the textbox. For example, if the slider is set at 65%, I can enter 0%, and it will just go right back to 65%.

I'm making a slider which will eventually control the alpha levels of a movieclip of mine but I'm having trouble controlling the parameters in the startDrag() function. Here is the code:
[Code]...
This seems to work ok, however, the problem is encountered when I go to drag the MC...for some unknown reason it ventures off its slider bar and goes to the left. I will attach the .fla.

I'm looking to make a slider bar reveal movie clips on my stage as you drag it along. I've written some sloppy code that works, but isn't smooth by any means. I basically put MCs on different frames on the timeline, and I want those MCs to fade in or out relative to where the pointer is on the bar. This was a workaround, what I think I need is a boolean solution, but I'm not familiar enough with AS to write one from scratch. Here is the code I have so far. Does anyone have any ideas?

I'm new to actionscript, I want to have a single animation and two sliders. slider1 will advance and rewind the movieclip,we'll call it "scrubbing", while slider2 will change the highest frame of the mc acheivable by the "scrub" slider1. Therefore if slider2 is at one end slider1 will not advance the mc at all, while if slider2 is maxed out then slider1 will "scrub" the whole movie.

I'm trying to create a tab system on my website. I have a small 25 pixel tall swf file at the top of the page that acts as the tabs. It uses PHP to communicate with the rest of the site. I have a larger swf below that acts as a directory to my files. When the user finds a file, he or she can open it in a new tab by clicking a certain button. And then switch between tabs using the top swf. I've got all of this down using AS3, but I'm not as good at the basic web design elements. How do I communicate to have every lower layer except for the one that the viewer wants to look at go to 0% alpha? Also, I cannot just have the tab system be all in one swf because some of the files that I want the user to open will be in AS2, which won't run inside an AS3 host.

this.addEventListener(MouseEvent.MOUSE_OVER,function() {
this.alpha=0
})
In an MC, I want it to become invisible when the mouse hovers over it. The reason I'm putting this code inside the MC and not making an instance out of it is because this MC will recur numerous times. The listener does work, as tested with trace(). For whatever reason, alpha doesn't.

i made text into a movie clip and put in this code to adjust the alpha.
onClipEvent (load){
this._alpha=100;
i=1;
}
onClipEvent (enterFrame) {
if(this._alpha=0 && i==0){
[Code]...
The alpha is going down.I think, because the text isnt there. What i'm having trouble with is getting it to go back and forth. Increasing and decreasing the alpha when it gets to it's maximum or minimum. I hope I'm making some sense.Does anyone have any ideas? And no I cannot do this with a simple motion tween because there are things happening in the background.

I'm blitting a map onto the screen with tiles.. and the source of these tiles are BitmapData objects.I know you can change the alpha of a bitmap.. but I'm not too sure if it can be done on the BitmapData object itself.I want some tiles to have less alpha than others. Applying the alpha to the Bitmap.. makes everything on the current screen have an alpha.. but I only need one tile of it..

I found this tutorial: [URL]. It works great but I wanted to add a little more to it. Currently it works with only one item displayed at a time. If I want to display more than one item, let say 2, I make the mask the size of the 2 items. The back button works fine because the X position is still the the same. However the next button does not account for the size of the mask and works like it did before.

I am changing colors of an mc dynamically, in this way: I have an mc of the color green for example. What I want is it to turn to a specific color in time. I have in that mc a sprite, that is that specific color (red in this case). iIset it's alpha to 0 and put it in the layer above the green part. Now when I set its alpha to 1, it will be that colour. When I set it to 0.5 ofcourse it'll be a mix between those colours. Is it faster to do it, but changing 0xFFFFFF? I wouldn't know how to do it though. i want to be able to tell it to go 3/4 of color nr 1 and 1/4 of color nr 2, for example. i also want to be able to choose those colours specificly, for the sake of art. so just choosing 0xFF0000 for red, wont do, for artistic reasons.

The thing should work like this: theres a movie clip in frame 10 of the timeline with two buttons inside, by clicking one of them the movie should jump to frame 15 and take the alpha of two Mc there (they are inside a different movie clip) to 0. This is what ie been trying (code on the button, btw):
on (release) {
McScene2.lettuce._alpha = 0;
McScene2.pumpkin._alpha = 0;

i really can't belive i'm asking this, but i've been about an hour trying to look after a solution for this but I couldnt find nothing. i'm trying to change a movieclip's alpha when the swf loads and when I press an existing button. the problem is that that movieclip is inside a button and as3 has a problem with it.
this is what i am trying to do in the first frame of the first scene.

I know how to change the alpha of one movie clip at a time on rollover, rollout, and release. But I'm a bit stuck trying to figure out how I would change the alpha of multiple movie clips, when one is clicked. It's for a simple photo gallery and I want all the thumbnails to darken once one has been clicked & the image is loading. I can't just fake it by having a somewhat transparent black movie clip appear over everything, because I need the alpha of each thumbnail to be able to change again once people roll over a new thumbnail.(a section of my code is included for reference but there are like 30 thumbnails so I didn't include it all, the code is the same for everything)
Code:
thumb_001.onRollOver = over;
thumb_001.onPress = down;
thumb_001.onRollOut = out;
thumb_001.onRelease () {
[code]....

i have this little display and when you click on certain items their alpha changes to 0.1, this worked fine until i added another frame with a different display on another frame. so now when you change frames and go to the new display then go back to the old display on frame 1 the alpha properties are all reset back to 1. So to fix this i thought i could simply add all the movieclips with an alpha less than one to an array when i left the frame then when you come back to the frame you could reset all the moviclips in that array back to having an alpha of 0.1. But this doesnt seem to work. here is the code i used.[code]But this code doesnt seem to work, the strange thing is even when i add some trace statements they tell me that the alpha does in fact equal 0.1 but visibally they haven't changed.

I am very new to Flash and I have the following script:
mouseInterval = setInterval(changeAlpha,10);
function changeAlpha(){ fader_mc.alpha = Math.round(root.mouseX/550*100) }
This is simply to change the Alpha of my object as I change the X value of the mouse cursor. I keep getting the following error message:
1120: Access of undefined property mouseInterval

for a periodic table tool I'm making, I've incorporated an effect that changes the alpha value whenever I hover over an element (pretty standard). I've noticed a mysterious gain in memory when hovering over my elements; using SYSTEM.TOTAL_MEMORY - there would be about 0.005MB increase in memory usage when I hover over an element, which isn't relinquished when I move my mouse off. However, if I move my mouse back on again, there isn't a second memory gain.
[Code]...
Does anyone know why this memory gain is happening when the alpha value is changed? And curiously why it only happens once? Some extra info: my Element class is a MovieClip, with a couple of TextFields, primitive variables and a MovieClip in it. It has had its mouseChildren property set to false (and buttonMode property set to true).

I have created a finite menu and it works fine, the only problem is that now I want to have the menu set to 50% alpha and when the user moves the mouse over the menu it gradually increases to 100%, Since I have never messed with Alpha's using action script.

I've been playing around with the presentation screens and slide in Flash, from browsing the web there seems to be very little if any information of how to control MC's within different parts of a presentation i.e. removing them or changing alpha. I've loaded an MC and now I'm am trying to remove it from the stage been experiment on the same slide and I just cant seem to get control of it.
I was using
_root.slide1.intromc._alpha = 0;
But this doesn't work for. How I can get access to MCs in a slide if its possible !!!!

I'm trying to make a URL-Loader Class to speed up my workflow, but I can't manage to make the images I am loading visible, turning their alpha to 1.
I use the following line to invoke my custom loader:
import com.ab.utils.Load
Load.Image(menuitem.holder_mc, menuitem.image, this)
[Code]....
Notice where I call a Tweener, trying to make my mc (_ITEM)'s alpha turn 1.
I tried thing like loader.content and loader.content.holder_mc, but to no avail.

What I have is a map that you can click on points and it will zoom in, you can also click on a "plus/minus" buttons to zoom in and out (I even have the mouse wheel zooming in and out). The client wanted me to add a "zoom slider bar" to it so you know you could move it up and down to scale it. Everything is working except the slider, I can't seem to get it to work with the position of the slider. All of the zoom functionality is there but the slider is killing me.
I am putting up the fla file since there is a lot of code in there and I didn't want to put it all in the forum. if you look in the fla in frame ten on line 726 you can find the function that is supposed to handle the zooming when you move the slider. Up on line 74 you can find the slider onPress and onRelease functions, but those I believe should be fine.
