Hi everyone,

I’ve been trying to make a waterbrush simulator in AS3. I’m doing so by using blurred circles and drawing them where the mouse is.

I’m adding a movieclip to everywhere the mouse is but it seems to bog down around 600 movieclips(sprites).

I have my scene set at 120fps which significantly drops around 600 movieclips.

I’ve tried grouping sprites with similar attributes into a parent movieclip and applying transforms to the parent but I get not significant speedups.

I’ve set cacheAsBitmap =true for both the individual circles and the parent movieclip.

In Flash it ultimately crashes at ~3000 movieclips. When I run it outside in the standalone flash player it goes much higher but same thing happens after 600 movieclips… it lags!

I was wonder if anyone knows of another way to do this or if there is an upper limit to how many sprites flash can actually support.

Thanks for any input.

other stats:  
XNA - point sprites 55000 units run at 60fps with my current hardware. of course this is 3D accelerated and flash is not.
