The wether forcast mentioned snow on Wednesday. We had some yesterday and today it is really snowing away. Looks like I'll have to buy a sledge for Lisa! Will be great fun.
Right now I'm sitting, writing about Qt's new animation classes released in 4.6. Looking at the snow, writing about this, makes me wonder if it wouldn't be a good idea to implement animations that delete themselves and their items when the item leaves a given bounding rectangle.
Why? Then you can define a bounding rectangle, e.g. the screen, and create snow flakes with randomized animations and just let them drop.
I remember doing something like that back in the STOS/AMOS days. You created a sprite, defined an animation pattern and then forgot about it (as I recall). This was great for the 2D shooters of the time with aliens attacking in predefined patterns. Not 100% sure how the surviving aliens (yes, you have to take bad players into account, including me) where handled. The ones you hit could be taken care of in a collision detection handing function called from the inner loop... well, nostalgia might make me look at this in a forgiving light.
Anyway, the snow is falling. There will be more tomorrow. It will probably be cold all the way to Christmas. Looks like we're in for a white Christmas.
