How can i do it so that the ball move if i press space bar not if im holding it so i press space and it moves the ball, rather than having to hold the key to move the ball the full distance.

Thanks

Set a flag that indicates that the space bar has been pressed and base your actions on the flag rather than the state of the spacebar.

A flag is basically some variable, usually an integer or a boolean. that's used to keep track of the status of something you're trying to.... well, keep track of. Let's say you want to use the space bar to toggle when something moves. The object is at rest. You hit the space bar and it begins to move. You hit the space bar again and it stops. I'm going to use pseudo code here since I don't have time to construct a full example.



elswhere in your main loop you should have something like



Integers can be used to track items that have multiple states, such as a stopped ball, slow ball, fast ball, no ball...., etc.

While I've had a long history of programming on and off (mostly c/c++) I really don't have the in depth understanding of Dark GDK nor do I have the time to devote to the pursuit. I'd love to be able to dedicate my efforts to game writing but I just have too many demands on my time.

The main thing you should realize is that the type of question you asked relates to a fairly general programming technique, just applied to something in a game program. Study not only the language you plan to use but also programming techniques in general. You'll need some of them as you get into more complex game requirements.
