Algorithm for moving the ball in pong game

[The Illusionist Mirage]

Hello

I am working on a pong game and I need some clue on how to make the ball move automatically. Like, when the game starts, the ball is stationary and at the center of the screen and when the player hits space bar, it starts t move towards the player's paddle and after colliding, moves automatically according to the angle of collision.

Thank You

You could look at the Pong SFML Example provided with SFML sources.

It's really easy to do, you just have to start the ball to move when space is pressed and then change the ball direction/angle each time it encounters a wall or a player

All you need is a velocity for the x and y and then move the ball by the velocity. Simply reverse the velocity when the ball hits the bat or wall. As for pressing space, just initialize the velocity as 0 then set it to whatever speed you want
