Flash :: Get Perfect Pixel Line Rendering In As3
Jan 7, 2010I'm making an arcade game in as3 and I want to draw pixely(unsmoothed by flash) lines. I'm drawing the pixels 'by hand'(not with flash's lineTo or anything) onto a bitmapdata object. The lines don't appear quite right though, when zoomed out the line is rendered 2 pixels thick at some parts. However by zooming it its apparent that the algorithm is fine and its not doubling the pixels. Changing the quality doesn't seem to change anything.

ActionScript 3.0 :: Blitting + Pixel Perfect Collision?
Oct 23, 2011I'm using a blitting engine that uses bitmapData. No display objects.Is there a fast pixel perfect collision detection available for such a game system?I already tried CDK but that didn't work because it assumes you have display objects which my objects don't use. Sometimes my objects are pretty big and hitTest sucks in this case. I already tried circle-to-circle collisions but that didn't do the trick either.

View 2 RepliesActionScript 2.0 :: Bitmap Hit Testing - Pixel Perfect Collisions
Mar 31, 2007I have been desperately searching for a way to do pixel perfect collisions, and for someone to explain it to me in detail. explain the code in the .fla file, posted by the Canadian in the frequently asked questions thread on bitmapData hit testing:
[Code]...
after looking through the help files, i must admit they are terribly vague. All you are doing is checking if _alpha is above a certain amount. With movieClips you would use 0->100 but with this hittest you have to use 0->255 (0x00->0xFF)so an _alpha of 50 would correspond to approx 128 (0x80). Nearly all the time you could just use 1 as a hittest parameter so you are checking for any hit at all but maybe you have a shadow in a mc layer and you do not want to check a hit. This is when you might be able to use your threshold parameter. In other words, the hit test will only react to parts of the bitmap which have a greater or equal alpha than the alpha threshold, mostly useful for a shadow.
Actionscript 3 :: Find A Pixel-perfect Collision Detection Function

View 2 RepliesActionScript 3.0 :: Pixel-perfect Collision Detection With 5000+ Particles?
Dec 5, 2009I just thought I'd drop a note here to those who are interested. I recently posted about it on my website and you can download the source for it there too. Here's some excerpts:
Ive run it at 60+ FPS with 7,000 particles, but that actually isnt the limitation (unless your particles are crunching heavy math for eg movement). Rather its the size and number of sprites that were colliding with the particles.
To squeeze all the juice out of Flash I employed a couple tricks. The first was the particles themselvestheyre blitted to a single bitmap which is used as the source image for grabbing collision data from. The particles are also drawn with the raster engine in Flash (multiple setPixel32() ops to give the illusion of a line a choppy one anyway) instead of the vector renderer (lineTo()).
The second trick was to only grab a Vector of pixels from the regions we cared about (within sprite boundaries) every so often, then to loop through the Vector and test it against our desired conditions. Also, since the particle bitmap is more sparse than our sprites as far as opaque pixels go, we test the particle bitmap first, resulting in a lot fewer passes on the first round of conditional statements.
That's the gist of it, but I explain it a bit more in detail in the post. Hope someone finds this useful and please let me know if you come up with something cool using it
Professional :: Buttons Don't Work When Test Movie/Test Scene?
Aug 4, 2011My buttons only work when I click on them on the stage while having the "enable simple buttons" option on. They do not work if I try to "test movie," "test scene" and publish it to a SWF. Nothing responds whenever I am in these modes. I am using Adobe Flash Professional CS5 Actionscript 2.0.
This is the code that I put in for the buttons:

Flex :: Comparing Bitmap Data In AS3 Pixel For Pixel
Mar 30, 2010I am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

View 7 RepliesProfessional :: Move Mouse 100 Pixel On Left Or Right?
Mar 22, 2010URL...when you enter the yellow zone, there is a zoom in and a zoom out when you leave, When you click the button you go back through the zoom out action. Everything is working as planned.However, if you go on the extended menu, then click on the edge of the button, you will enter a loop action of opening, closing opening, closing.I have identified the problem, but i am unable to fix it.In the Menuidle, the yellow zone have:on (rollOver) {gotoAndPlay ("Menuzoomin", 1);}Which is the one the script require to detect the enter of the mouse in the zone when you come from the outside this script is also the one causing problem because when you click on the edge of the button in the Menuopen, the button itself is zoomed - 40 %,thus reducing his detection box by 40 % too. This cause your mouse to "enter" the yellow circle and cause the Menuidle script to kick's in and want to open it.and because you are on the edge of the button, you get a loop.
You can also notice the mouse cursor switching back and forth.Is there a way to prevent that ? someway to tell Flash to not play the script in the yellow zone until the mouse is competly out of the zone ? not just the button itself but the whole yellow zone, Then refresh the script if the viewer return on the yellow zone so we start to zoom again.Or even to move the mouse 100 pixel on the left or the right ?I even tryed reducing or enlarging the hit zone of the button itself, it dont do anything.
Professional :: Change The Pixel Size To Anamorphic?
May 23, 2010I'm trying to create a credits screen for a movie that's 1440x1080, anamorphic. Flash CS5, on the other hand, only allows square pixels, which throws off the pictures/text when I put it into Premiere Pro CS5. So, is there any way to change the pixels from square, to 1.33?
View 5 RepliesProfessional :: Pixel Colors In BitmapData.noise?
Oct 5, 2010I am wondering if there is any way to set the pixel colors exclusively to black and white (instead of gray) in a bitmapData.noise animation. The previous related thread is: [URL]..For the function:
function makeNoise():void { _bitmapData.noise(getTimer(), 100, 255, 7, true);
Is there any way to set the noise color pattern to black and white? In the scripting reference, it seems the choices are R||G||B||Alpha channels, so I am not sure if there is any way to combine these to get black and white only.
Flash :: Professional - Template In CS4 - Changing The Pixel Size
Feb 10, 2010I am new to Flash and was trying to start a website for my photography business. I have an up and running version of Flash Pro CS4 with all updates. I purchased a full flash template from [URL] hoping to just open the .fla file and go to work editing. No such luck. When I click on the main.fla file, all the components seem to load in the library, however in the timeline, I only show like 9 random layers. When I run the timeline, all I get is a bunch of lines, squares, etc running on and off the stage. When I click "publish" the layers and components run fine with all the default content. The template came in a ZIP file and after extracting, I get the usual files, .fla, .html, .XML, .SWA, etc. All the components seem to be in the .fla file. What am I missing? I know there should be more layers in the timeline, but I cant find them. My troubleshooting has been to confirm that the template is good with CS4 and ActionScript 3.0. I've tried different settings to include changing the pixel size, but nothing.

View 3 RepliesProfessional :: Restricting Decimal Point Positioning - Using Whole Pixel Numbers?
Mar 2, 2010I've frequently come across the issue when placing a movieclip or bitmap, the resting position of said object will land on a decimal value, not a nice, full pixel value. For instance, I drag a movie clip into a scene and it lands on a position of: X: 27.2, Y: 56.9, when I'd like it to be X: 27, Y: 57.
Now, this wouldn't bother me as much if I were dealing only in vector shapes. I currently work as a developer in the videogame industry and often times, for optimization purposes, I need to use both bitmaps and vectors. Plus, as a UI designer, text is very important to use throughout a game's UI. If you notice, when a font gets placed in an in-between position related to pixels, the text becomes blurry looking in appearance (graphical elements around the text can also appear blurry when in between pixel values as well). This can make UI pages or HUDs look sloppy and unprofessional.
I've tried enabling snapping (including enabling the grid, setting the grid to 1x1 pixel, then enabling both pixel snapping and grid snapping), but nothing seems to help in getting objects to place on whole pixels. Yes, I can manually change pixel values to whole numbers (which I'm currently doing). But when you have to manually position 100 keys on a keyboard, it gets old pretty quick!

Professional :: Ecard Suggested Stage Size - What Optimal Pixel Dimensions Would Be For Ecards To Run On Multiple Platforms
Feb 15, 2011I have one that's almost done and the stage size is 700x800 px. But I'm starting to worry if that's going to look too small? To change it, will be a lot of work - there's animation, imported Jpegs etc. As far as I can tell, in order for it to look correct in larger dimensions I will need to basically create it again from the ground up. So, I'd really like to get an idea of what the optimal pixel dimensions would be for ecards to run on multiple platforms.
I really want to do this and I don't feel like I can move ahead until I get the viewing size correct. I don't even mind redoing the card. I just want my future cards to be the correct size. I don't want to have to come back and redo them all. By the way, the cards are being made in Flash. The site itself will be created in DreamWeaver.
