I have created a composition in after effects with a video layer and 4 different shape layers. The shapes all move around tracking objects on the video. I want to be able to turn the visible property of these shapes on and off at will during playback.
I have converted their key frames to cue points, and then exported the flv. The shapes have key frames at the same time throughout the video resulting in multiple cue points at the exact same time.
In flash I am only able to listen to the cue point that is dispatched from the lowest layer of my after effects composition. So for example on frame 10, layer 1 and 3 both have a key frame changing the position of the shape. Using the script in after effects I've converted these to cue points. So I now have 2 cue points on frame 10. My program in flash will only hear the cue point dispatched by layer 1, and seemingly ignore the cue point from layer 3.
Is there anyway for me to listen to multiple cue points at the same time? Or am I going to have to go about this another way entirely?
I can't find any information that multiple simultaneous cue points isn't supported but trying to add two cue point at the same time code in Adobe Media Encoder gives an error – indicating that you should probably avoid it.
Another solution would be to collect all the transformations for a given keyframe and collect them in the parameter list for a single cue point. An example could be:
layerChangeCue
layer1 : "x:123;y:456;s:0.78"
⋮
layer4 : "x:123;y:456;s:0.78"

So for my latest Flash project, I'm designing a game. The dimetric character can move in 8 directions. I've been given the spritesheets for the hats, hair styles, etc., that the player can wear.
The spritesheets contain the images for each direction, AND they contain four frames of animation (four per direction) for when the player is walking. This is basically the layout of the Spritesheet (and all of the files and "frames" are the same size, which makes things easier):
[IDLE] [WALKING]
[S][SE][E][N][NW][W][S1][S2][S3][S4][SE1][SE2]...
My goal is to embed all of the items in a single file other than the main one. But I need to implement walking animation.
One thought I had is to set the main SWF's framerate to 7 FPS, then use an Event.ENTER_FRAME handler to alternate between the walking ones. Programmatically animating.
Another thought is to create SWFs for each item of clothing, then use motion tweening to move the spritesheet symbol over the stage.
What I'd really like it so avoid using Adobe Animate entirely. Even if there's an approach that requires the use of Flex, I'd take it if it meant saying goodbye to graphically-designing.
using flash builder (flex) does not mean that good bye graphic! there is a relationship between Adobe Flash and any As3 Ide like FlashBuilder or FlashDevelop.

i dont undrestand! why 7 fps and also why Event.ENTER_FRAME
there might be a character movieclip, whit above frames in its time line, well! to playing any animation (for particular direction) you have to call mc.gotoAndPlay("walk_S"); then it will be played automatically, if you need lower frame rate, only select each frame by mouse pointer and then press [F5] in time line to insert a blank frame gape between keyframes.
as i said before, you must use a callback script at the end frame of the each loop animation like walk_s walk_ne ...
also idle animations must be called like it: mc.gotoAndStop("idle_s");
I'm writing a painting application with canvas in HTML5.
I've finished my pencil painting with touching and drawing.
And now i'm trying to make a rectangle. For all the topic i've read, i will have to store all of my finished shape in an array, but if i do that, i will also have to store all the point with normal drawing so that i could draw a rectangle like windows painting.
Please give me another solution to draw rectangle like windows, which old rectangle will be dissappeared and new one will replace before i make a "mouse up".
thanks in advance :)
You will either need to save the previous drawings or use 2 canvases.
If you want to save the previous drawings...
In mousedown:
Save the mouse position (startX/startY).
Set a flag indicating that a drag has started (isDown=true)
In mousemove:
if isDown==false, don't do anything (return)
otherwise, clear the canvas
redraw all your previous drawings (from your saved points array, etc)
draw the current rect from the start to mouse position -- context.strokeRect(startX,startY,mouseX-startX,mouseY-startY)
In mouseup:
clear the drag flag (isDown=false)
If you want to use 2 canvases...
As an alternative to storing every previous drawing, you can use 2 canvases. One canvas is used to draw the current rectangle and a second canvas to keep all the previously draw items Here's an example using 2 canvases so you don't have to store previous drawings: jsfiddle.net/m1erickson/V9J5J/
this is a newer version to a question i have asked before but have not received an answer to.
I am developing a mobile AIR app with many animations and tests have shown that using bitmaps and GPU rendering give the best performance across all mobile models. I receive normal vector animations from the app's artists, and have built a system which loops through these animations at runtime and draws the content into bitmapdatas.
my concern is looping through the movieclip's frames. If I have these lines of code:
for (var i:uint=1; i<mc.totalFrames+1; i++) {
mc.gotoAndStop(i);
bitmapData.draw(mc);
}
I can't be sure the frame got "constructed" before being drawn, and my tests with an Android tablet prove this right - sometimes frames aren't drawn.
This mc is off the display list obviously (we dont need to render to the screen). So is there a way to make sure the frame has been built before drawing it to a bitmapdata? (and waiting for FRAME_CONSTRUCTED, EXIT_FRAME, etc.. is obviously slow and unneeded)
any ideas?
thanx
Saar
more info to clarify:
this is a children's book. each page has animations in it. all these animations are vector animations in timelines in FLAs I receive from the devloping artists (not the users).
Every page has an FLA which i publish to a swf.
what i actually do is replace vector animations in loaded SWFs with bitmap version of them.
At app runtime, upon each new page, i load the swf, go though all the animations in it (looping through the content's children) and each movieclip i rasterize into array of bitmapdatas.
My custom "Bitmap Movieclip" places on the displaylist a replcaement bitmap for each movieclip, and on ENTER_FRAME i switch the bitmaps' bitmapdatas from the array.
this gives very hight performance
I'd suggest use a splash screen, and place your MC to be converted to the bitmap to the stage first, then draw to your bitmapData. Several issues had me force to put a DisplayObject being drawn to the stage before actual drawing once already, so this might be a quick fix for you too.
var splashBD:BitmapData=new BitmapData(stage.stageWidth,stage.stageHeight,false,0xffffff);
var splashBM:Bitmap=new Bitmap(splashBD); // draw a thing as needed here
addChild(splashBM);
addChildAt(MC_to_convert,getChildIndex(splashBM));
// then advance it by frames and draw.
sorry MY BAD
waiting for FRAME_CONSTRUCTED is the answer
I am working with Flash CS5, and haven't been using Flash since the age of AS2.
I have a movieclip symbol in which I have an Actions layer, in which I have a keyframe in frame 1 and one in frame 20. Each of these should have a stop(); action assigned, but when i select the one in frame 20 and start writing, the little "a" appears on frame 1 of another layer. When I make a keyframe in frame 20 of that layer and try to assign actions it yields the same result. They appear on frame 1.
Is this a bug or am I missing some vital information about AS3?
AS3 is in fact more picky (for good reason) about how the code is implemented.
You need to select the keyframe you are intending to put code into, and then use your actions window. And as Markus commented, make sure you're using keyframes, and not empty frames. If you try to write code into an empty frame, it will default it to the most recent keyframe.
Furthermore, If you have multiple layers and say, your code is on layer2 and your objects on layer1, if you have keyframes on layer1, and intend to enter code at frame 20, but your layer selection is layer2, it will yield the same result described above. You'll have to make sure the correct layer is active. The actions window will only display the code from the current layer's most recent keyframe.
Hope that clears some things up!
I'm working with a few designers, each of whom have created 3D animations (using fp 10 capabilities) for use in the same flash application. Each 3D animation is a unique movieclip that will ultimately be part of the same .fla file.
The problem I'm having is that each of the movieclips was created in a separate .fla, and each .fla had different settings for the vanishing point for the stage. This means that after importing the various moveiclips into my library, none of the visual assets are aligned as they were in their source .flas.
The good news is that only one of these movieclips is displayed at a time, so I don't need to be able to have multiple vanishing points; all I need to do is change the global vanishing point programmatically at various points during runtime.
What should I do? I've tried accessing root.transform.perspectiveProjection.projectionCenter and dynamically assigning it new Point(x, y) values, but they don't seem to be having any effect on the 3D movieclips.
Thanks!
Each clip can have it's own vanishing point, try checking what the instances of their movieclips has for that value (transform.perspectiveProjection.projectionCenter)
How about using localToGlobal to calculate the new point for each of the various movieclips?
