Manage many sprites

[serge]

Hi,

I'm doing an aplication where I have to manage many objects at the same time, some of them are static and some are moving, right now i'm just using one sprite for each object in the screen, of course the performance is very poor. I could implemet a function to set the statics objects as part of the background, but fist at all I'd like to know if there is an optimized way to do it. I hope somebody could help me and provide me with an example.

Thank you and regards

You should not add "static" sprites. Each sprite is redrawn (and checked for collision events) every tick.

You can use the ImageLib library to draw on a Bitmap object.
Afterward draw the bitmap with GameWindow.DrawBackgroundImage2.
