I was told the pixel detection is costly for regular windows games. Is this the same for flash ?? Or would pixel detection be lighter compared to other detections flash has to offer. Flash has the getPixel32 method which makes it easy for detecting pixels. If I am bliting my game, would it be wise to use getPixel32 for collision detection. Or should I just check for specific tiles ??
Is getPixel32 limited to the display object it is in ?? In other words, can I detect any pixel regardless of what layer it is on in the display list.
And lastly, I probably can figure this out on my own but I want to ask first to save me some time. But does anyone have any code or good sources on how to go about doing this if it is reasonable.
In just about any environment, I’d rather use primitives like rectangles and circles instead of pixels for my collision detection. You can usually build a reasonable representation of your sprites out of such primitives and get a real performance boost.
