1.) Is it possible copy a part of the screen to the memory and paste it to the certain place. RawSaveScreen() and RawRestoreScreen() only copies and pastes all the screen.
2.) Is it possible to solve a certain pixel color on the screen?
3.) Is it possible dynamically draw to sprite with same way as draw to screen with RawDraw...() functions?
1.) Not yet. (http://www.adventuregamestudio.co.uk/tracker.php?action=detail&id=519)
2.) No, and even if it's to be implemented we need to find some way to solve possible ambiguity caused, since if your game is high res (640x400, 640x480 and 800x600) each game coordinate actually contains 2x2=4 screen pixels.
3.) Not yet, I think I had raised it as a minor suggestion some months ago, but I'm too lazy to dig the thread up.
Guy, if you have several short questions, please post them all as a single thread. Thank you.
Btw, these are the tracker entries you're looking for:
1.) RawRestoreArea (http://www.adventuregamestudio.co.uk/tracker.php?action=detail&id=483)
3.) RawDraw on sprites (http://www.adventuregamestudio.co.uk/tracker.php?action=detail&id=194)
