cacheAsBitmap help

[Deviant1853]

Ive been playing with Flash 8 latley particularly with the filters, but I would love to see cacheAsBitmap working.

The way I am implementing it is:


var myMovieClip:MovieClip = this.attachMovie("point","point",this.getNextHighestDepth());
myMovieClip.cacheAsBitmap = true;

I dont see any improvment in performance on large content movies. Am I doing something wrong?

you can see some examples here:

You may just need a situation which uses it more effectively. I cant tell what you're doing with what you've provided

Thanks for those, I have seen them before though. I am doing a basic 3d engine, and I have several hundred vertex's. The problem is it slows down because of so many object moving. I wanted to use it to test the cacheAsBitmap option in Flash 8 to see if there is any improvment.

The problem is im not sure if im implementing it properly.

I suspect that if you're redrawing polys each frame then caching might not be of much use to you. I can't comment for sure though as it's not clear exactly what is being cached.

if you read the help in Flash it shows you where you can turn it on at runtime, if this doesn't help I have seen it used as

onMouseMove = function()
{
mc1.cacheAsBitmap = true;
};

Thanks for the help but the main problem was that I couldnt cache the item because it was changing constantly :)

[emolen]

did you fix that? cause I'm working with bitmapdisplacent and attempting to cache it, but it is also constantly changing. It seems to be helping but after a while flash player or whatever just crashes. Any ideas whay.

cacheAsBitmap works good only for the graphics elements who does not get updated internally (its own timeline) otherwise it has redraw problems.....
