choppy in flash

[brett]

Hi,
I am making a game that runs perfectly as an exe but as an swf it runs choppy. It still works but is not smooth. Any ideas what may cause this or how to fix it? Thanks,
Brett

Hard to say. Some critical stuff: fastloops, size and number of Actives, fine collision detection, Actives not inactivated when far from playfield, alpha channels, semi-transparency...

Hi,
How do you inactivate actives when they are far from the play area? Also, how does fine detection have an effect on speed? Should I change frame rate or any other application properties? Thanks,
Brett

1. In the active properties.

Hi,
I figured out how to inactivate actives when far from frame. This seemed to help significantly. Thanks,
Brett

Set frame rate to 60, since that's the default for monitors and will give you the smoothest picture on most monitors. Fine detection only slows down collision events, so if you have a lot of those on roughly square objects it's nice to turn off.

I e-mailed Francois about this, and he suggested that it might be a problem with the speed of collision detection; and I use FastLoops (not consistent ones, but still, I run a couple every now and then)

When observing the Frame Rate in flash, it didn't fall below 60. I feel that the problem is likely to be what Jacob has pointed out; vertical sync. I'm not sure if there is a way you can make a Flash app v-sync with the monitors frame rate. I only get the problem when I move Active Objects (not using fine detection) at more than 2 pixels per frame in any direction.

I can create a blank application, a single active object, and Always +2 or more to its X position, low and behold, choppy movement in Flash. Then again, could just be me... :P

Can you try to put a counter that displays the number of frames per seconds (in the storyboard object expression)?
