ActionScript 3.0 :: Making A Slider Adjust Brightness?
May 23, 2010
I am having a few difficulties trying to add a slider to adjust the brightness of a movie clip. So when i slide the slider to the left it changes to a dark skin tone and to the right a lighter skin tone.
how can i adjust brightness with actionscript,is just that im a begginer and only know to adjust alpha, but now I want to adjust the brightness to a graphic that`s inside a movie,

I have imported all SliderEvents , ColorTransform, and Sprite events.. I defined each variable and gave both my 'image' and 'panel' their instance names.
My 'bValue' textfield has been given the instance name of 'bValue' .... here's the file to show you all what I mean.
What else do I need to do for this to actually do something??? I studied a little as3 in the past and learnt how to make mc's and that's about it...
I'm loading a bunch of images through XML like this:
[Code]...
Pretty simple. Loads each image into a imgHolder_mc named 0, 1, 2, etc. Each image is also set to alpha = 0 since I don't want them to show unless the slider is changed.
this may seem like an odd question. well after spending ages getting my slider to act like I want I now want it to stop at a certain point - but to act 'naturally' - basically the slider accelerates the more a button is pressed and uses a set deceleration number to slow down the slider when the button is unclicked. So the faster its going the longer and further the slider takes to slow down - 'ease' down. when it reaches zero it stops.
If you click on the blue arrow in the movie youll see what i mean. The problem comes up when i want to get the slider to stop. I want the slider not to go beyond a certain point (say 600). This gets very difficult if the slider is to act naturally (as before). I guess some kind of reverse engineering is required that works out what point to start the slow down based on where the slider is and what speed its going at??
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.
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.
I am trying to create a basic timeline, similar to the timeline we all use in flash (see attached).
I have a playhead slider, which when dragged, just drags within its startDrag() limits.
I also have horizontal window scroller which also when dragged, just drags within its startDrag() limits.
I am trying to work out how to get the horizontal window scroller to scroll when the playhead slider hits the left or right edge. I am using hittest for this collision.
I have the playHeadSlider scrolling along the top. When playHeadSlider collides with hittestThing I want mcContents to then move.
It kind of works.. mcContents moves when the playHeadSlider is in collision with the hittestThing.. but it just moves rather than 'drags' across. I have it set up so that mcContents is twice the width (approx) of mcScrollWindow.
I need to somehow update what I have so that if the playHeadSlider collides with hittestThing on the right, mcContents only moves to the right and if playHeadSlider collides with hittestThing2 on the left, mcContents only moves to the left.
I have a movieclip acting as a button and when the mouse rolls over it I would like the symbol to brighten slightly. Is there a way to do this in actionscript 3?
is there any way to control the brightness of a movie clip or button on mouse roll over so that it gets brighter when the mouse is on it? I could only find things for earlier versions of AS and i couldnt figure out how to change them..
I was working on a project a few months ago, which I had to put on hold but am finally getting back to. One major feature I need that I wasn't able to figure out before was how to measure the average brightness of an image file loaded as a movieclip. I remember spending hours going through tutorials but I wasn't able to get it working. Now I don't even remember what or where I read before and I'm not keen on rereading all of it and still not knowing what to do.
I just want the simplest possible way to get an average brightness level of an image, I don't care which way the brightness is measured as it is only important relative to other images which will be measured the same way.
How can I change the brightness of a MovieClip dynamically through actionscript? I've seen a few examples online but none of them are working too well.
Does anyone know how to control the brightness of a movieclip through action script. I can't seem to find the syntax for that property (if there is such a thing).
What I'm trying to achieve is have my images "flash/shine" when the cursor passes over the image, however; I want it to adjust to say +100, then back down to 0 immediately, not on roll out. The code I have thus far works perfectly fine for over and out.
On the main timeline I have a graphic of a hill and tree that darkens when clicking a button. I also have a movieclip called "creature" that has a little creature walking from one end of the stage across to the other. I need a script that will control the brightness of the "creature" movieclip at the point where the main timeline animation goes dark because the "creature" movieclip sticks out like a sore thumb at that point and needs to be darkened.
Is there any fringe api to increase the screen brightness in adobe air for android? I am making a morse code app and it could really use a pump in brightness while the app is in use. If its not yet implemented, then this would definitely make a nice addition.
I would like to ask that how can I use the webcam in AS2 for brightness/darkness detection.I've found many topics in motion detection, but they are not useful for me, and they are too complex.hat I want is only an image with alpha level which is react with the light in the room. If the webcam get a dark image (the light are turned off in the room)The alpha of the image goes to 0
Is there a color transform tool that lets me affect the brightness of colored pixels only? For example, if I have an image that has a lot of grays and blacks, but a colored dot in the center, is it possible to only affect the brightness of the colored portion?
The solution I'm looking for does not involve making the colored dot in the center its own movie clip, just so you know.
