Professional :: Does CacheAsBitmap Helps For Performance Of Shape Tweens
Aug 2, 2010
I have an image converted into MovieClip (background) and I have a mask MovieClip (bgMask) set to mask the image MovieClip like this:
[Code]....
In bgMask I have a few linear gradient shapes which I animate with shape tweens using keyframes. If I don't set cacheAsBitmap for both, nothing will happen since what I need is alpha masking and it will work only then. In this scenario is cacheAsBitmap working for me or agains me? (not that I have any choice). Still I could try to replace some of the shape tweens with MovieClips with solid shape in them and just move them around to uncover some part of the background, and where I want a smoother transition I would stick to the shape tweens. If the object that I've set cacheAsBitmap true to is no longer being animated moved sized and so on, would it be better to set cacheAsBitmap to it to false?
I'm trying to save a file that has several shape tweens. I create the tweens and preview the file and everything works perfectly. However, when I save it and reopen the file, the tweens are gone.
I am trying to animate using a heirarchy of symbols and motion/shape tweens for the first time. I have my character built using symbols and groups of them are already in subgroups (I click on one symbol and I can go into that one and there's more inside that). When I go into my character's eye symbol and click the upper eyelid, I can shape tween a blink. It works fine when I scrub through the timeline while still in the character's eye symbol and it still shows up when I publish a preview. But when I go out of that symbol to the top of the hierarchy and play the animation in the frame, I can't see the blink. I don't know why it's happening, but I can't edit all my shapes without knowing where the ones I've already moved are.
Have recently made a few educational activities which are experiencing performance problems on older machines. Basically, tweens are not completing and causing things to behave strangely.I don't think it's the well-known garbage collection problem with tweens not completing as I use TweenMax for all the tweens. Also, on any half-decent machine, everything works correctly but if tested on an old laptop it all goes a bit wrong.
EDIT: I've not got around to adding a pre-loader yet so things might take a while to download..
I've been experimenting with shape tweens using the line tool to make stick figures, and using shape tweens to make the figures move around. It's great fun, but I've been running into a particularly disruptive problem. For example, I'll have a stick figure in one spot at frame 1. I move it across the screen using a shape tween, and bend one of his arms over the course of 10 or so frames. The problem is, Flash seems to be misinterpreting what ought to happen during the tween. Instead of just bending the arm, Flash makes the arm rotate in a full circle. It still ends up where it ought to at Frame 10, but it takes the wrong path to get there. I've attached a video to illustrate what I mean. Look at the upper body piece right at the end. Is there any way I can fix this without having to animate frame by frame?[code]...
I'm trying to mask multiple shape tweens for a slideshow animation I'm working on. (the transition would look just like the main animation on this page url...)
Everything works fine when I'm only masking/tweening one shape. But as soon as I add a few more dquares to the mix everything goes to hell. Can someone tell me the most efficient way to have multiple shapes tweening, while masking an image underneath them?
i'm doing a project that i need to do color shape tweens and i'm doing it the stupidest way but it's the only way that i know.. i'm doing all the probabilities but i'm sure this can be done easily with action script. in this example that i'm show i only have 3 colours but in my project i'll need to use 6 colours and 5 diferent objects and it makes a lot of probabilities [URL]
I'm working on a slide show which includes 3 sections that fade in and out automatically as well as can be navigated via buttons.Everything is working fine until I include a 3d tween animation of a hanging sign.it doesn't have any action script - just a 3d tween where the sign swings however once I include it in the slide show, the whole thing goes crazy:The fade in and out of tweens don't work.sometimes the slide show skips and everything start moving very fast as if the timeline was fast forwarded... can someone please helpe me and point me in the right direction of where to even start trouble shooting it? The problem is that it acts as if there was some kind of script added however there's no action script included in the hanging sign.
using the shape tool you can draw basic shapesthen using the subselection tool you can re-shape them by relocating certain points
What i want to do is create a tween whereby one of the points is movedthe problem is you have to convert to a symbol first and after you have done that you cant change the shapes shape.so how do i go about using a motion tween to change the shape of a shape?
When I want to ask for a small fee for my app, I'm not allowed to use TweenLite. So I started thinking I could probably replace the tweens with Flash's built-in Tweens. BUT I'm also using rotationY. Flash doesn't support this as far as I know. Are there Tween engines out there with a copyleft?
I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
I'm new to Flash, In CS4, is it possible to add two consecutive tweens to the same object (symbol instance)? Say I want to have a shape move in from the left, wait a few seconds, and then move back out towards the left. Thus far, the only method I've found is to create a copy of the object (a new instance of the symbol), and animate it separately. But that creates extra objects, and getting the positioning right is very difficult. Isn't there a way to have one tween end and another begin (possibly after a delay) on the same object in the same layer? Or in different layers, which might be preferable?
I seem to remember reading that you shouldn't do it.I was mad at Flash CS4 and CS5 because I wasn't able to make the animation work like After Effects, as far as animating something, having it rest, and then animating it again. I know you can do this already, however, if you add easing you could mess yourself up as the ease gets applied to the entire tween. I wanted to be able to tween something with an ease, then let it rest, then tween it again, again with an ease.
Tonight I discovered this: Place CTI over last frame of first tween, select object, copy. Go to next "slot" and Insert Blank Keyframe, then Paste in Place the object. Make some more frames. Then after it all make a New Keyframe (content from preceeding keyframe gets copied into it, then add more frames, select them and Make Tween. I now have 2 tweens on the same layer, each with their own easing that can't get stretched out of place.However, when I did this I noticed, before making the second tween, that I was not able to just click the object and Make Tween from there. I had to actually make regular frames and convert them
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.
I have created an app in CS5.5 for Android and iOS. I have tested on two Android devices and everyingthing works fine. However, on an iPad and iPhone the animations are really slow. Here are some more facts:
1) My project has many scenes and in the problems scene there are upwards of 1,200 frames. But even simple animations run slowly.
2) The frame rate is set for 24 fps.
3) I have created a universal app (iphone and ipad), publish resolution is standard at full screen.
4) Ironically, I have already tried caching as bitmap. That actually slowed my animations even more. I am truely at the end of the line here and don't have any possible solutions.
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 have created a series of classic tweens in one layer starting on frame 30 through frame 60. How can I shrink just those frames and scale the tweens with them so they are proportionate to what I had originally, without moving those frames over before frame 30? So I want them to still start on frame 30 but I want to end at 47 now instead with the tweens still there and proportionate distances that I had originally set up?
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'm creating a flash website in AS3 where the user can click a fullscreenbutton which works fine. Im not using the hardware mode because of the black borders it creates and I dont want that. The site is liquid in a sense it conforms to the browsers' size using Event.RESIZE.
I'm using TweenLite to make transitions between pages and it works fine
UNTIL
I release fullscreen mode (escape) and go back to the browser. From then on all my transitions are extremely choppy (like 1 - 2 fps) and I can't figure out why. I had video on the pages but even when I completely removed the video from the pages the transitions are still choppy. When I go back to fullscreen the transitions are smooth again.
Looking for some recommendations on tools that can be used independent of the source (that is just on the swf) to check for Frames Per Second, total size and how often the movie loops.
I am trying to improve the frame rate of a game that draws many floor tiles. Currently, the floor tiles are vector graphics and stored as different frames in a movie clip. I wanted to experiment with rasterizing a floor tile and seeing if that would provide any frame rate boosts. I did this by converting one of my tiles (one of the frames in my movie clip) to a png and replacing the vector version of this tile with this raster version. I then tested two worlds--one filled with tile A (vector) and another filled with tile B (png).
In all my tests, world with tile A (the original vector version) outperformed the world with tile B. I am guessing that the reason I am not getting the expected performance gains is because I am still rendering the tiles in the old style and not using any strict bitmap drawing calls?why it is that this method fails to boost rendering speed? Would I have to switch my rendering code to strict bitmap draw calls?
Trying to see if someone can guide me to a way I could stop my earlier tweens and onRollOver function when my onPress function is launched. What I worked out here with that McX/YScale.stop(); and that target9_mc.onRollOver = null; is kind of working but I don't want the onRollOver function to stop until the onPress function begins.
I have Adobe Flash CS 5 and have been having difficulties trying to get a created tween to move at a constant speed. I have been converting a graphic I've created to a symbol and turning it into a motion tween, however I have only figured out how to move the tween on a frame by frame basis. Is there a way I can map out the full trajectory of the tween and then set it to travel along that pathway at a constant speed rather than moving from point to point within a certain number of frames? The desired result is a green circle that will bounce off the edges of the computer screen/window as it moves along at a constant speed in the appropriate direction. I am a flash novice and have been fiddling with the program for a few days
