Hi Wondered if someone could give me some advice. I am working ona project where a user can pick an avatar and enter chatrooms. The idea is to display the avatrs to represent people in the different rooms. Currently there are around 25 different heads and bodies (which can be mixed andmatched) and 6 different images for a character. I currently have a nested movie clip that pulls in info form xml and the structure of the clip is something like: frame that loads in intial fornt facing head and body into seperate clips frame that houses a "walker clip". this contains 4 movie clips one for the head and 3 for each frame of walk animation Ideally i would like to be able to cache these images so i am not downlaoding the same assets over and over. Can someone point me in right direction to acheive this? the simpler the better;) I.e would it be as easy as jsut checking the runtime bitmap cache on the properties box for each moivie clip? Or is that overly optmisitc (namely bitmpa cache shouldt be usedofr animation?) and i need to do soemthing more extensive? any help would be great here. regards

- 1. scrollpane pain
I am trying to create a slide show using the scrollpane. I created a movie called mc_gallery that has a scrollpane on the left side of the screen. I added a movie clip inside the scrollpane (called navVertical) that consists of 10 buttons stacked vertically. When the user clicks one of the buttons what I want to happen is to load a picture to the right of the scrollpane ( on the mc_gallery). So I added on (Release) { imagePath2 = "images/hospitality/h1A.jpg"; _parent.updateSlide(imagePath2); } to each of the buttons. I have a function defined on the gallery called updateSlide that uses loadMovie to display a larger jpg image. If I put the raw navVertical on the stage everything works...Click a button and the corresponding image appears. But I canNOT get this same logic to work when the navVertical movie clip is inside of the scrollpane. I would like to call the updateSlide function so that I can do a few other things once the name of the slide is passed to it, but frankly at this point I will settle just to see the large image appear on the right side of the stage when on of the button inside the scrollPAIN is clicked. please advise... - 2. text box required
can anyone help me with a piece of code to stop someone moving on with out having some info into a text box? I have an ok button that is clicked to move on - but i want the user to type something into the text box before they can move on. if they dont type anything then they cannot move on - any ideas? - 3. how do I access movie properties
Hi, I have created a movie clip, dragged an instance onto the stage and name it EMPTY. I then use loadMovie to load an exernal jpeg into EMPTY. loadMovie(currentPainting, EMPTY); I use onClipEvent to set the position of EMPTY. Iwould like to use the height and width of EMPTY to position another object on ain stage, however, I cannot access the height and width of EMPTY except for within EMPTY's clipevent. I've tried accessing the propert with EMPTY._height, and I've tried setting a global variable withinthe clipEvent and then acessing that variable, but to no avail Any idea? .

the cacheAsBitmap property of movieclips is used to retrieve a movieclip bitmap from memory instead of requiring the flash player to (re)render the bitmap repeatedly. that's only helpful in certain situations including (but not limited) to a movieclip that's not changing frames. if you mean you want to cache some asset so it doesn't need to be repeatedly downloaded that happens automatically with flash unless you take steps to prevent it and has nothing to do with the cacheAsBitmap property of movieclips.

ah ok cheers. so...........the way i a have my clips set up so that they load the relevant frames in from xml.... I(t literally does an xml call duplicates as many avatar holders as needed and then loads int he right body parts) will these loads be ignored if those images are already cached? I just want to make sure i reduce as much overhead as possbile. thanks in advance

1.bitmap caching for bitmap movies
hi, i know this sounds silly, but i am a perfectionist. Currently i am developing a game and i am planning to increase the engine's performance as much as possible. I have a movieclip which has some bitmaps of different positions for my character. I wonder if enabling runtime bitmap cache for this movieclip increases the rendering performance. thanks in advance...
what is the property feature "use runtime bitmap caching" used for? mousing over the checkbox gives an explanation, which i understand, but i don't know why you would use it. i think it may help with a problem i'm having too and wanted to check with you guys to see what you use it for and the consequences, if any, of using it. i have movie clips that have images loaded into them from an xml file. so mc1 is on the stage, in frame 1, with an instance name of mc1. in the actions layer of this frame, my script loads an image into the clip via an xml file. all works fine and good. now in frame 2 i want to re-position mc1 into the same position that mc2 is located. whenever i copy the instance from the previous frame, then manually re-position it.... all is still well, the images load fine. however, whenever i just rename the instance name of mc2 to mc1, the image doesn't stay loaded into the clip? why not?
Hello, A quick question about caching bitmaps inside of flash, i have a couple of layers of bitmap images that are static items on the screen and won't be moving. If I add them to a movieclip and enable bitmap caching will this cause them to be rendered once by the flash player? I understand this functionality works on vectors and then causes them to be rendered as a bitmap and then cached does the same happen for raster images? many thanks Stefan
4.Allow smoothing for stuff created by Bitmap caching
Here's the deal. Normally, when you animate a Bitmap, the motion is very jerky due to pixel approximation. To get around this, you choose "allow smoothing" for the Bitmap in the Library. However, as of Flash 8 we now have Bitmap caching which will basically convert your vectors into Bitmaps at runtime. All filters, for instance, do this. The result is jerky motion. The fix would be if there's some way to set allow smoothing. I haven't found a way. Anybody know of any solutions?
