Professional :: CS5.5 JSFL: Timeline.convertToKeyframes() Doesn't Work With Motion Tweens
Oct 26, 2011
I'm writing a JSFL script to export animations from Flash. I iterate through every frame in the timeline, and for each frame I go through every element in every layer, and write each Element's symbol name and matrix values out to a file. The problem is, if you've created animation using a motion tween, the exporter steps through every frame but sees the same matrix values for each Element in every frame. This is where I hit the first problem: Iterating through the timeline in this way doesn't seem to work. I can't see any way of getting the right information out for each frame.
There is a workaround: Namely, selecting all the animated layers on the timeline, and selecting "Convert to Frame by Frame animation" from the context menu. Then you run the exporter, and then you have to undo the "Convert to Frame by Frame" animation in order to continue working on the file. That's pretty messy, so I tried to automate the process, by having the export script perform the convert to frame by frame. When you perform the action, and look it up in the History window, Flash tells you that the JSFL command it used was the following:
I am still making some language flashcards. there are about 20 on the page. when i click the card it is supposed to 'flip' so you can see the translation. the first card does pretty well but then as I continue to the next cards, the tween becomes worse and worse. for some reason as the card flips, its dimensions get thrown off and it becomes really wide or really tall. I want the flip to be a strictly horizontal flip over the y axis. What am I doing wrong?
I created an animation with various symbols and motion tweens, mostly on outer level timeline. At the end, I realized the resolution was too low for a quality quicktime export. After scaling the canvas from 550x400 to 1650x1200, I tried scaling the rest of the objects using the "edit multiple frames" brackets, but every scene I try to do this to, only a few of the frames are scaled. They start scaling and moving around all over the place fluctuating between the original and new positions. So i have to go back and manually scale/reposition the tween spans. Am I doing something wrong with the edit multiple frames thing or something? Or is there an easier way to do this I haven't seen?
I am wanting to create a button that, when pressed, will make an image move along the X axis. However, I want several other buttons to move that object along the X-axis to other locations regardless of where it is currently.
I want the object to move from one spot to a second spot, stop, and then move from that new location to either its previous spot or a new spot.
Basically having multiple buttons controlling where 1 or more image goes. I have seen banners that will scroll horizontally when you click different Menu buttons. The banner slides along the X-axis and stops to reveal the name of the new page on the banner (i.e. Home, About Us, Contact Us, etc.). When another menu button is pressed, the banner slides again to reveal the new title page name (ie. Home, etc).
I've been going over several tutorials and whatnot and I'm confused on the point of movie clip symbols and motion tweens. To me using the other tweens and symbols are "easier". Can someone explain to me why they're so beneficial to have been added to CS4/CS5? Except I understand that movie clip symbols can be adjusted using the 3D tools but is that the only difference?
i've been looking around for answers to my problem to no avail. What I want to do is create a powerpoint style presentation. But rather than change slides, I have one large "graphic" that I am moving around and zooming into by "motion tweening" Now all I need to do is: (with a keyboard event) start the motion tween and then let it play out then start the next motion tween and let it play out and so on. all i have is this, which allows me to start and stop it when it is tweening, but isn't as effective as it stopping at then end of a motion tween, then allowing me to push a key and for it to go to the next "slide"
I just finished animating a scene with multiple layers and multiple motion tweens on those layers. But after testing it, i decided that it is too fast. Does anyone know how to scale everything on the timeline without changing the framerate?Also, how can i scale the size (transform) an object that already has a motion tween applied to it? I want to scale it on each frame in the animation, not just the first. I've tried, and it changes the animation where i scale it on the timeline.
"How many motion tweens can you have on a timeline." Yup. The answer is one...... or is it? I had a long discussion with my tutor (who is the greatest tutor in the world) and he wanted to think about it. I said to him that I thought that one motion tween was wrong because you can click on an object in the timeline, make it a motion tween, and double click it and make several motion tweens. So, essentially, you can have more than one motion tween on a timeline.
For some reason I cannot Create Motion Tweens. I have followed step by step instructions, and using exercise files from Lynda. The symbol from the Lynda files is a movie clip, and I resize it according to the demo - step by step. Selecting "Create Motion Tweens" from the menu does not actually create motion tweens. I have also tried from scratch in new files. I am using CS4 on Windows 7, and I have created motion tweens before. I must have made some change somewhere else in Flash to cause this to stop working.
I making an animation for a preloader.In the animation, a 'line' draws a picuture.There are many lines,and I would like a mask to follow the lines so that it appears that they are being drawn.There are so many that it would be difficult to do this manually by moving a mask frame by frame with motion tweens.
I've used the stop(); function on my actions frame, top layer, on all of my frames. I've tried using it on keyframes for all of the frames, and on one "master" actionscript frame (spans the movie).
stop(); won't stop my master timeline. I've traced it, and it isn't being activated--so that tells me that for some reason, the actions on the frames (not in the document class file) aren't being triggered.
Is it related to the fact that I have a custom document class? I can't think of anything in there that would cause this to happen, and I even put a stop(); in the beginning of the constructor function. (Didn't work so I took it out.)
This isn't a looping movie clip inside of my timeline, it is the master timeline itself.
I have a presentation with two set of buttons.Clicking on the set which is on the Frame (2) Should redirect to the set of buttons Frame (3),(4),(5),(6),(7)As you can see in the image, the (2) gives the order to go to the next (3) and it works.But when it goes from (2) to (5) or (6) or (7) then the second set of buttons don't work anymore.[URL]
I'm working in Flash CS4 and I can't see my timeline (or playhead) in the Motion Editor.I've never experienced this before and have no idea how to remedy the issue
I have spent many frustrating hours trying to figure out why this is happening. It is totally broken. I need to use a motion path using 3d in a symbol. Because of the way the project is put together (for Flex) there are several FLAs that need to be converted to symbols.
So when I convert the FLA that contains a motion path with 3D, the object moves away from the path in the symbol (the 1st frame remains in place, but everything else is off the path), even though it remains correct in the main timeline.
And once I start editing the object in the symbol, the object returns to the path ok, as if it had been some strange display issue, but the 3D is all wrong - the vanishing point relative to the object has changed. The same thing happens whether I create the 3D path using "global" or "local" tool settings.
i'm loading an external swf files in one but the buttons inside the external files wich controls its timeline doesn't work, i'm using AS3 but why it doesn't work.The external file just has some simple actions to move between keyframes in the timeline with buttons goto and some other similar actions
I'm struggling through trying to learn the new tween system. Is it just me or did they completely NUKE workflow with this new system? Is there any way to copy and paste the property keyframes?I often have animations where things loop, so the last frame of the motion tween needs to be the same as the first frame. In the old days I would just select and copy multiple keyframes from frame 1 and paste them at the end. Done in 5 seconds. The only way I can find to do this now is to hand set every freaking property on every freaking keyframe of every freaking object.
I have scoured the web reading tutorials and lots of them discuss getting an object from point a to b.I simply want to move an object from left to right (no problem) pause for 20 frames, and then drop down.
I can accomplish it a few ways but it seems to involve way too many cryptic steps. One solution is fairly easy to implement but the resulting timeline visualization is really poor.[code]...
I have been working on this banner ad using motion tweens (with scaling) for four objects, three road signs and a background. Sometimes it runs very smoothly, but most of the time, the four objects run in a very jagged way? Does it have to do with four motion tweens happening at the same time?
I'm brand new to Flash (started last week). Playing with motion tween editing and thought I understood the difference between using the selection versus sub-selection tools.BUT...... Under certain circumstances (and I haven't been able to get a "handle" on what those circumstances might be), I seem to get a control point on EVERY frame, whether a key-frame exists at that point or NOT on the TL (also, whether I got the sel or sub-sel tool selected makes no difference).
IF you copy a motion tween as an AS how do you insert the code so that it still performs the motion?I created a motion tween, copied it, deleted all frames, made just 1 frame, placed the object on the frame (from the library with the same name used in the original tween) pasted the AS onto that frame of the relevant layer but it does not work
When I first started playing with the new motion tweens I realized that you cannot copy keyframe "properties" on multiple layers at once. You have to copy them one at a time. But I just found out that if you select the multiple property keyframes you can hold Alt and drag to duplicate them all at once.
so i watched the tut on motion tweens on how to change the color of stuff, but i guess im doing something wrong because its not working.are there step by step directions i can follow? also how would one change the color of a gradiant over time?
I am fairly new to flash and I'm currently using CS4 to create shape tweens that morph from a shape (in my case an astroid, not to be confused with an asteroid) to text that I have broken apart into individual shapes. This works very well with the shape tweens; however, I would like to use symbols instead of shapes for my tween.
Naturally, I converted my shape and my broken apart text to symbols and then set up a motion tween. My research has told me that you cannot morph from one symbol to another using ANY tween, but this would not make sense to me.
Am I missing how to actually do this? If it is true that you cannot morph between symbols, then why on earth hasn't Adobe made a way to do this. If I need to substitute one shape for another in a flash video, and I have this shape in 100s of frames in the video, there is NO way to quickly find and replace those shapes, especially if you've duplicated the the several (20) times in each frame.
I have a problem, which I couldn't solve. I made three motion tweens. One is the background, which slides in from left. Another one, is a car, which goes in the scene from right. The two visible wheels of this car are spinning too using a motion tween. The problem is that all these motion tweens keep looping. I would like to let the background and the wheels of the car loop forever, but I want the car to come in from right and stop on the left. When I tried to stop it, it stopped the car, but unfotunately it stopped the background too. How could I manage to let the background and the wheels of the car loop, but stop the car in a position?[URL]
I am trying in CS4 to change visibility of some motion tweens using AS2 _visible=true and _visible=false ( I need to stick to AS2)I am able to successfully target the motion tweens that are not masked, but I can not target the motion tweens that ARE masked. The masks lie directly over the tweens within the same movie clip as the other tweens.
