ActionScript 2.0 :: Fake Perspective Transformation Jazz
Mar 29, 2012
Basically that method of fitting a bitmap texture onto a parallelogram, by splitting the parallelogram into two triangles and skew/shearing the two separate copies of the texture to be lined up with it's respective triangle.Senocular wrote a pretty good tutorial on it, but I'm stuck on some little details and or conceptual stuff, I'm not sure.First question, in the transform matrix, the b and c multipliers (skew and shear), what does it mean exactly? I played around with it and found that shearing by a factor of one, the angle formed by the slope (the slope of the two top or bottom 'points') of the shape was 45˚. So, 1 = 45; 0.5 = 22.5, etc. Am I on the right track or was the 45 angle observation just a coincidence? If so, how exactly do I find the skew factor?

When I right-click a symbol the options "set transformation point" and "reset transformation point" come up. They don't seem to do anything for me. I thought it would center them or something. This is not the case. I have the white transformation point in one corner in one keyframe and a different corner in another keyframe I click "reset transformation point" on both frames and they don't move.

Without being able to modify the prototype chain, is it possible to fake multiple inheritance in AS3?
Say I have three Window classes. One is a DraggableWindow, one is a ScalingWindow, and one is a BorderWindow.
I want to mix and match new subclasses at runtime without having to make tons of new permutations of Window subclass possibilities.
Sure, I can implement these behaviors of the Window class as interfaces, but I would still have to account for all the permutations of interface combinations.

I'm learning AS3 and I'm trying to build a little interaction where I can throw a square off the stage. It just need to stay on the x-axis, to be thrown either to the left or right.I found quite a few tutorials where it involves physics. I don't need anything as complicated as that. With mine, as long as you click down on the square and throw it a bit, doesn'tmatter how hard that throwing action is, the square will always be thrown off the stage, depending on the direction of your mouse.I kind of have the idea in my head that the "throw" feel can be done with tween in a movieclip (since it only need to go to either left or right), which will be activated depending on the direction of the mouse.

The following code is how you call a function with an event listener. There is a disadvantage to this however: you can -only- call loginCheck with a MouseEvent. If I want to call the function through code, I can't just write loginCheck(); and have it work.
[Code]...
But I have always wondered if there was a way to run a function with a MouseEvent parameter through code. Is there any way to fake a MouseEvent and send it as a parameter to the function?

I have yet to find a good and simple tutorial regaurding the skinning of the scrollBar component so I am trying to fake it...
Simply put I have MC buttons underneath the scroll bar and the bar itself is invisible... I need to know what the name of the actual scrubber bar (the one you drag arround) is called so i can attach a movieClip to it and match it's width/height and X position
does anyone know it? --- or Can someone simply explain how i would go about actually skinning it? Everything i have seen says open haloTheme or sampleTheme and edit those but I just want to change it once (not perminantly).

I want a generic function that lets me align a child object to the bottom edge of a parent object. The problem is that the parent object can either be a simple movie clip or the Stage. With Stage, I would have to use the stageHeight property rather than the normal height propery.

Is it possible to set a buffer of 10 minutes to either Flash Media Live Encoder or Flash Media Streaming Server? We're considering setting up a live stream for a gaming tournament, but we are concerned about players being able to cheat by watching the live stream while they play.

where I can find a tutorial or information about how to make a fake 3d effect by using several layers that move at different speeds when you move the mouse. See [URL] projectx and click on 'Evolution of snowboarding'. Simulating 3d by moving three or more layers at different speeds related to mouse pointer offset from the center of the stage.

I listen to internet radio at [URL] and it works pretty well, except for one minor issue. The Flash applet that runs the radio player has a timer on it, where if you don't move the mouse over the player every once in a while, it decides you're idle and shuts off the stream, even if you're not actually idle, but just working on something else with the radio player running in the background.
Is there any way I can send a fake MouseOver message to this applet to keep it from cutting me off in the middle of a song, maybe with a GreaseMonkey script? I'm using Firefox.

i am looking for script for movie Clip distortion and 3D transformation in action script 2.0

I'm playing around with Flash CS4 trial and tried to 'compose' a 3d Box by putting 6 MovieClips as the side elements of the box in one clip which represents the whole box. (only using the Flash Tools, no Actionscript). Within the BoxClip (after doubleclick on the BoxClip on stage), all sides look right, each side is positioned with the correct angles and coordinates. Outside the BoxClip, back on root stage, the box sides are not parallel anymore, the angles are not 90 degrees, there is no 'box' actually. So I guess, one of the problems is the 3D Center point of the objects which is absolute to one point in coordinate space. The other problem is the faulty '3D' display in Flash, that is, changing from inside to ouside a clip changes the view also. So far, the Flash GUI seems quite useless for doing some '3D'. How to improve the workflow?

Place a 100px by 100px box on the stage (not a movieclip, just a simple shape).
Now apply a vertical skew of 30 degrees. You should get this...
Click outside of the shape to release the transformation data. The degrees for skew resets to 0 (this is expected), see image below
But What skew would you apply to the shape to return it to its original shape. Initially I would've thought it was -30 in the vertical skew, but this seems to return a weird hybrid shape.. See below:

i am developing a kind of (near-)isometric engine (in Actionscript 2.0), kinda simple, which is using MovieClips as wall or floor textures.This is the Wall texture i have:This is what i would like to have:The height is always 1.5 times the width. Its a simple skew transformation.Currently i have two possibilities:I am creating the finished wall in photoshop, save the file as PNG (because of transparent areas). Because i cant import PNGs at run time, i need to create all possible textured walls. A lot of work if i have a lot of textures (Say, i have about 200? )I am importing the original Texture into Flash, and perform a free transform directly in the MovieClip. I still have a lot of work because i have to do this to each textured wall!I would like to do this transformation in Actionscript, so i could import any texture JPG at the runtime (LoadMovie) and just need to have the File names stored somewhere or retrieve them and so on.
I didnt find any possibility to perform a skew transform to a MovieClip in Actionscript..The transformation is just like this: Rotate by 45 deg. (CW) and reduce the height of the finished transformation to 1/2.i am able to apply the _rotation and _height transformations, but the second transformation is always applied to the root object, which often might be very helpful, but right now its not.

I'm developing a flash product designer... one of it's features is that customers can add their own text to product and they can move it, resize it, rotate it... but I have one problem - text is stored in dynamic TextField with embed fonts, it's created dynamically from Actionscript, but it's registration point is set to upper left corner, is there any way to transform it around center? I mean resizing and rotating around center.

I want a chart that has several separate series running in rows across. They are largely separate charts and should not overlap, but all share the same horizontal datetimeaxis. They don't share the same y-axis, however and that's where I'm getting stuck.I have tried having a linechart series and then a plotchart series, but it will only allow a single <mx:series> per chart without having them inside the same series which as far as I can tell will place the charts on top of each other in the z-axis. I can stack them and have them completely separate charts, but it was proving to be somewhat irritating having them align correctly.
Is there any reasonable way of combining multiple charts into one like this? Basically having rows in a table where each row is a different chart but the columns are consistent. or am I going to be best served just by stacking separate ones? an illustration of what i'm going for is here: http:[url]........

I would like to have a MovieClip that has a bit of depth. I can't use rotationX, rotationY or rotationZ because I have to use Flash CS3. The first image is what I have now, a flat movieclip. The second is what I should have.
I already tried using a matrix, but that didn't work. I posed a question about it, and there somebody sugested that I should use a 3D engine to get the result I want.

I've tried in vein to understand displacement maps; I can find nothing on "The Internet" that teaches me what I need to learn. Now I'm looking to all you smart-types to solve my problem for me! All I want to is take an image (a rectangle) and make it look like it's going off into the distance (trapezoid-like), getting smaller from left to right. This doesn't even need to animate, I just need two states: straight-on and trapezoid-like -- think iTunes album art browser minus the bells & whistles. I know this can be accomplished with a displacement map, but I know not how to get 'er done.

I am creating an interface where a user can pick up "Polaroid" stle photos and shuffle them around a virtual desktop. I want to photo to shift it's transform point to match the point at which the user picked up the photo, to create a "swinging" effect as the photo is dragged.there was an AS2 workaround floating around, but I want to find the AS3 equivalent, and seem to be unable to find it in the Geom/Matrix package/classes.

I'm making a very simple animated flight plan with 3 airfields and six airplanes as seen from the top. To imitate the effect of take off and landing I want to be able to change the size of the plane when it flies.Only trouble is I can do that only with the Free Transform Tool. Even if I select Modify -> Transform -> Scale I have to change the shape of each object manually and they end up having different sizes. I tried editing the size in the properties box but the fields are greyed out. Any idea how I can change that.

This is giving me such a headache.I have a movie clip and it has a centered registration point but the transformation point is in the top left corner. I want both to be in the center of the MC. I want a little circle with cross-hairs in t in the middle of my MC, if at all possible without moving my MC. But I cannot get that damn cross-hair to budge from the top left corner! When I go into the info window and change the X-Y values of the transformation point, the whole MC just moves to a new position. The infuriating things is, I've done it before but I just can't seem to work out what I did. Please don't tell me to drag the registration point in free transform mode. I can do that, but I cannot drag the transformation point in the same way.

Why are the scale x and y options grayed out on the motion editor? I tried editing width and height (W&H) in the "properties panel" under "position and size" and all that does is move the position my object diagonally for some reason, not scale the size. Also, when i do this, the Width number does not change, but the x and y position numbers above it change. Strange!

I have transformation matrix properties (a,b,c,d). How to calculate scaleX, scaleY, scewX, scewY and rotation angle from those values?
When only one type of transformation is applied, I can figure out that:
scaleX = a
scaleY = d
scewX = c
scewY = b
rotation = arccos(a) or -arcsin(c)
But when multiple transformations are applied at once I don't know how to calculate those values.
I need to do this outside of flash so I can't use any flash helper methods.
