In AS3 – after drawing into the graphics canvas of a DisplayObject using beginFill(), does closing the fill
using endFill() impact (improve) performance or memory consumption?
Or does it merely closes the fill so that you can start a new one elsewhere?
I have used this methods a lot in intensive applications (videogames) and tried to learn about this too. I never noticed any differences so I would say it does not affect performance or memory consumption. I think it just changes a flag so that it doesn’t fill other shapes you draw later.
However, I couldn’t find any “official” sources confirming or denying this so I am not 100% positive. I’m sorry but this is the best answer I can give you 😉
