IDE :: BitmapData Button Based Scrolling
Feb 12, 2010
I've checked out a lot of the tutorials on this subject on the internet and they are overly elaborate, involving cameras, in previous versions of flash i would have just messed around with x and y values and xscales and y scales.Anyway my problems is I have a single bitmapdata image of perlinnoise 500x500 on a 500x500 stage. I'm trying to do this all in code.Now I have a few buttons at the bottom. ScrollLeft, ScrollDown, ZoomOut Etc.However when i make a listener to my buttons using Mouse Down im only getting a single increment of scrolling [code]When i click and hold the mouse on the button im just getting 1 pixel of movement, what i want to see is the scene move smoothly while i have the mouse held down.Additionally .scroll doesnt seem to work with floats?

i'm trying to setup a scrolling list of products but without the use of a scrollbar. It would be really thankful if someone would assist me in getting attached fla integrated with mouse based scrolling. So if the user moves his mouse to the upper corner of the product list then it would scroll up and vice-versa.

I tried my best to search the forum before posting, but if this issue has already been addressed, I apologise in advance. My goal is to create a movieclip that will scroll vertically based on mouse movement, rather than mouse position.I've found many tutorials on the yugop scrolling menu, but my problem with this menu is that the scrolling continues even when the mouse has stopped moving, if the mouse position is on either side of the stage.

I am currently working on a interactive map that I am building in flash. I need to figure out if there is a way to code something so that we can have our map zoomed in, so it is only showing a section of the map in the veiwport at a time, but when the mouse reaches the edge of the screen I want it to automatically scroll with it, up, down, over, etc.

I have a strip of thumbnails in an MC that is quite long. I am masking this long strip of thumbnails so only a few can be seen at a time. I want the user to be able to move this strip to the right and left based on where their mouse is.But a lot of the solutions I've seen have used the stage width to achieve this...however, I only want the strip to move if they are over the 'active' area.....basically if they are over the mask area.And then when it reaches the end of the strip

I'm making a side-scrolling game, with a (theoretically) infinite background. I have a block engine that places the blocks on the bitmap canvas. Now here's the catch. I'm using the bitmapData.scroll() function. Now unless I clear the screen each time the character moves, it's going to leave ghost images of the border of the screen, like this picture: zanzlanz. tumblr. com/post/18857712784 If I clear the screen each time, then it generates a lot of lag (because it has to repaint the objects again). I'm a bit lost on how I can scroll without leaving streaks of the side of the screen and without repainting the entire screen.

I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:
ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData()
at Reflect()
at Site_fla::GalleryPage_29/loadThumbs()
at Site_fla::GalleryPage_29/sortXML()
[Code]...
btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..

I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

I've made a mobile version of my software, with low-res images and such, and I can now fully buffer all my content (including a 360 frame animation which is buffered to memory). Problem is, that everytime I update the view, more memory is used.When I write image = new BitmapData();, does it store the previously created BitmapData's in memory? Do I have to flush the memory somehow before I draw my second picture in BitmapData?Example:

i using an XML driven gallery(Scotty*) and what i would like to do is add a button thats actions update with each picture to open a specific external link either another web page or just a larger version of an image. i have done my best to sift my way thru the epic tut on XML here on Kirupa but i just cant seem to nail down what i need to add or where to add it to make this happen.my supsicions are that it needs to be updated on the load image function some how as i also want the text for the button to be specific for each item ( " launch project " , " open lg image " ,etc. )and as far as the button action itself could there just be a simple function that could be made that would dynamically seek out the XML for the current item's URL?

I am having an issue with using BitmapData.draw(stage). I am getting the following error:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///C|/Documents%20and%20Settings/bla...bla...bla.swf cannot access null. No policy files granted access. Here is a portion of my code:
var bd:BitmapData = new BitmapData(2800, 2100); bd.draw(stage);//this is where the error happens All of the files referenced (.xml/.jpg/.swf) are located in the same local folder as the main .swf. How do I get around this error? The main objective is to print the stage using PrintJob(). I am using Flash Professional CS5.5 and publishing to Flash 10.0/10.1. Let me know if I need to supply any more info.

I am using Flash CS3 and Action Script 2.0 I have created a test file. See Attached
I am looking for AS to control a scrollbar with a button. Jump to headline location.
First, I have 3 buttons. Red, Blue and Yellow. Second, I have a scrollbar window with text in it. The scrollbar moves to any part of the text. The first paragraph is for the Red text, the second for the Blue text and third is Yellow text.
When you click on the "Red" button the scrollbar should move to the RED TEXT headline. When you click on the "Blue" button it should move to the BLUE TEXT headline. And the same for the Yellow.

Im new to AS3 (like 5 hours new) and Im after getting stuck with something Im sure is very simple, but Im just not having much luck finding a solution. Basically I have a button which I want to click and hold and then make a movieclip move up and down the y axis. This is what I have so far...
[Code]...
Im sure Im probably going about it in a bizarre way, Im just trying to do it in a way which makes sense to me. So far its working fine for single clicks, so I click the button and the "upwards" function is called which moves the movieclip upwards by 10. The problem Im having is getting it to move continously when the button is clicked and held. Ive read a few possible suggestions relating to loops and setinterval but I just cant seem to make sense of them in a way that applies to what I want to do. Apologies if this is really simple but Ive literally been teaching myself actionscript for all of about 5 hours in total so far and I just cant seem to get past this hurdle.

I'm building a historical timeline app in Flash. The main feature will be an MC containing links to specific event in the history of an organization. The MC will scroll, and there will be a couple ways to scroll it. One type of navigation will be fwd/backward buttons, and I want them to work such that if the button is pressed and held, an MC containing links will scroll w/increasing speed (up to a limit), but if the button is clicked, it will just move the MC a specified amt.
An example of what I want to accomplish can be seen it this HP timeline: [URL]
I think I could do this w/a MOUSE_UP eventListener

I have just followed the tutorial on the scrolling window, but instead of one button for each page, want to have just one up and down button. If you know what I mean. Maybe an array of y places and when I press the down button it goes down one. Really don't know where to start.

Right now I got a problem creating a drop down menu , which drops down the menu when a mouse hovers the panel.The panel is a Button.The Drop Down Menu is a MovieClip.I added an MouseEvent.MOUSE_OVER and MouseEvent.MOUSE_OUT for the panel(Button). And the EventListeners will do the animation of the drop down menu -- fade in and out using TweenLite.However, this cause a serious problem: since the MouseEventtargets the Button only, when I roll over The Drop Down Menu, it will perform MouseEvent.MOUSE_OUT since it roll out the Button!The only thing I can think of is using addchild() which add the Drop Down Menu to the Button so the hit area of the Button extends. But I cannot use addchild() method on a Button which don't have addchild().here's my code:
ActionScript Code:
