----------------------------------- metachief Mon Feb 04, 2008 5:47 pm sprite help again corrected ----------------------------------- what my code does is: whn i press either 'a' or 'd' then i hvae a bunch of pictures drawn (movement of a character). PROBLE: the problem is that when i press one of the two keys it draws the pictures nonstop untill the last one is drawn. For example: if key ('a') then loop right := false left := true Pic.Draw (pic1l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic2l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic3l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic4l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic5l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic6l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic7l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic8l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic9l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls Pic.Draw (pic10l, round (x - 70), round (y), picMerge) x := x - run_s delay (60) View.Update cls exit end loop end if in this it will exit when picture "pic10l" is drawn. WHAT I WANT IT TO DO: i wan it to stop drawing when the key that i press is released. so for example when it is on picture "pic5l", i want it to stop on the picture when i let go of the button i pressed.

Thus, if the key is pressed once, the whole group of Pic.Draws acts; but since you want to keep the stream of sprites if the button is kept down, you will have to check if the button WAS down a second ago when you last checked the keyboard and still IS down now. Thus, you will have have to store information regarding the last state of the computer in the memory. Think of how to do that, then figure out how you could recall which sprite it is you want to draw and how you could manipulate that value to act as it should if the the key is held down.
