Title: Need help making a shape move automatically
Post by: nevets_19 on May 19, 2011, 10:52:13 am

Hello, i am new to SFML and i wanna just do a simple program where u press an arrow key and the ball moves in the direction until you press space bar, i know in visual basic you can get timers which do this very easily (shape.left = shape.left + 1) can u make a timer function in SFML and it constantly does the action like in Visual Basic

This shouldn't be done with timers.

In game programming you typically have a loop which drives all logic.  It usually looks something like this:

Code: [Select]


while( game_is_running )
{
    ProcessEvents();

    UpdateWorld();

    DrawWorld();
}


You would then updates all objects in your 'UpdateWorld' function.  So you could call

Code: [Select]

yourball.Update(); which would move it in whatever direction it's going.
