ActionScript 2.0 :: Use Light Dependant Resistors To Change The Alpha Of A Mc?
Nov 5, 2005
I'm currently using flash with a teleo board (hooks flash up to little electronic inputs) and im trying to use light dependant resistors to change the alpha of a mc.
The light dependant resistors give flash a reading between 0 and 32. 32 being bright light, 0 being complete darkness. Now I want to use those numbers to make an object 100% opaque in complete darkness (reading 0), and 0% in complete lightness (reading 32) then all percentages inbetween
['Code]...
Now that code works. but it does it the wrong way round. everything is 100% on reading 32. and everything is 0% on 0. I need reading 32 to = 0% and reading 0 to = 100%...im tired and can't see what to do to swap the figures around.
This is for a personal art project, however I have hit a potential (Actionscript) brick wall! I want the diameter of the 'balls' orbit to change dependant on the position of the mouse but keep the point of rotation exactly the middle of the stage at all times. I.e. if the mouse is hovering over the exact center (both X+Y) of the stage then the 'ball' should have a tiny diameter of rotation (but contstantly follows the orbit in clockwise direction) whilst if you move the mouse towards the edge of the stage then the diameter of the orbit of the ball will increase. Here is the AS which controls a blank movieclip;
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%
I am trying to dynamically change the alpha value of a set of movieclips on a timer. The timer works but I get an error message from the function. This is the error:
TypeError: Error #1010: A term is undefined and has no properties. at piedacoulisse_timer_fla:MainTimeline/zoom/piedacoulisse_timer_fla:onT ime()[piedacoulisse_timer_fla.MainTimeline::frame1:124] at
Im very new in the flash business and i started making a gallery after this videoi get 2 errors when i write te action code for alpha change. Is it because i use ActionScript3 instead of 2? because i made it with flash CS3.
Basically, I want to change the alpha value on my movieclip. I start my mc with an alpha of .08 (8%). mc.alpha = .08; What I then want to do is increment it to .9 (90%) and when it hits that, decrement it back to .08, and then when it hits that, increment it again to .9 etc.
I have tried if(mc.alpha==.9){ mc.alpha -= .01; }else{ mc.alpha += .01; }
From what I understand you can change the alpha value of a textfield to be fully transparent. I would like to have chat output that fades after a while. I was wondering if there was a way to change just a portion of the string inside of a text field to transparent. The textColor does not have an alpha value. I could just use multiple text fields but I would like to avoid doing that if possible for efficiency sake.
I'm making a drawing API for my homepage. My homepage is exclusively created in Flash AS2... But I have a problem with my brush for the drawing API... I would like to change the opacity/alpha value of the brush, with keypress LEFT and RIGHT... But i can't get it to work!
Ok. I am new again so I hope I am describing this correctly. I don't know the best way to do this but this is what I've dreamed up so far: I have a number of movie clips on my screen, all thumbnail sized images, each with an instance name (ex: tw_lifeoftheparty, tw_xmen, tw_xfiles, tw_diehard, etc.).
In each movieclip there are 2 layers: the thumbnail image(bottom layer) and a black border(top layer). The black border is an object named wk_border and isin each of the thumbnail movieclips.
I have given wk_border the same instance name in each thumbnail movieclip "border"
Let me try to explain what I'm doing. I have multiple movieClips (mc_aitkin, mc_anoka, there will be a lot more) on the stage that I want to change their alpha using data from an xml when it loads. I can isolate the info I want and trace it so it shows in output, but I'm not sure how to use it from there.
I've tried to convert the xml data to a number and do an if/else as shown below, but the only output I get is "not" (from a trace). So I'm guessing the if/else isn't recognizing the xml data as a number?
If I can resolve that, the next step will be to apply this function to the large number of mc's I'll have on the stage. Would that be with something like e.currentTarget.alpha = .5; ?? I don't think I can put it in the same changeAlpha function because there the property of 'e' would be undefined.[code]...
I want to make a button to change the alpha of an instance but I dont know how to make it.
Thats what I want: When I click the button, then the movie clip appears (alpha 100)When I click the button again, then the movie clip disappears (alpha 0)
I've been trying to change an MCs alpha with actionscipt. the movies FPS is 30. Here's the as: onClipEvent(load) { var alpha = blue._alpha; alpha = 50; var forwardA = true; var changeA = true; [Code] ..... Btw, "blue" is the MC that I want to change the alpha of, and this code is on that MC.
I am quite new to actionscript 3 here is what I want to do: When the mouse hovers over a movieclip I want another movie clips alpha to go from 0% to 100% then when the mouse moves off of the movie clip the reverse happens.
I am working on a project for school using ActionScript 3. I have a matrix created with an animated movie clip. The matrix looks like a bunch of shapes changing size and color on the screen. I would like to have it so when I move my mouse moves over an individual shape in the matrix the alpha will change to be more transparent... like 0.5. I'm sure it would be a mouse move function, but I don't know how to write that part of the code.[code]...
I have 10 movie clips on the stage all of them are on the same layer and the alpha property at 0.5.
I want a single movie clip to randomly move to the top of the other at timed intervals. This movie clip alpha property will change to 1 while the other movie clip will remain at 0.5
is it possible to to change the value of the alpha setting of an attachedMovie
I have
Code: function attachBk (thisBk, nextBk):Void { if (thisBk == undefined) { this.attachMovie(nextBk,"bkHolder1", this.getNextHighestDepth());
[Code]....
When I click a button I want bkHolder1 to fade out but so far I haven't had any success, I tried doing bkHolder1._alpha = 0 just to see if it would affect it's property but it didn't.
I have a bunch of thumbnails which I want to be treated the same on rollover/rollout/press. Right now, I have it working so that the alpha changes on all of them on rollover/rollout/press, but to do that, I have a code for each individual thumbnail, and I know there has to be a way to just have one code that applies to all of them instead of repeating so much (but I'm just not sure how to do it). This is what I have right now:
As far as I know theres in no way to change the alpha of a dynamic text box. I put one in a movie clip and when i try to change the alpha of it everything else in it changes its alpha but the not the DT box. can't change alpha and find a component that allows alpha control with a dynamic text box.
I'm new to action script and was wondering how to change the alpha of a movieclip from 0 to 100% gradually or instantly when the mouse is moved ( like the navigation bar on a media player) when the mouse is still i want the alpha to be at 0, i am totally new to actionscript but am familiar with code syntax.
I'm creating pages with text supported by wav files for training. on the bottom of the page is a progress bar. I want to make a button that when clicked will permenantly raise the alpha of a movie clip (on a different layer) to 100%. (it is currently set to 0) within the movie clip (hazpop) is a button that will turn the alpha to zero (click to close window) so in theory (not as2) it should be: on mousedown alpha.hazpop=100 I've been combing the forums for days and no-one is talking about alpha.
