Hey im trying to make a breakout type game but i cant figure out how to launch a ball from your paddle . i think i could figure out how to make it stop and bounce off the walls and blocks but i just need somethign to get it moving when you press the space bar. any help would be appreciated.

If spacekey() = 1 then move_flag = 1

if move_flag = 1 then move object ball, speed

or you could use variables to move your ball...

[Befor Loop]
XSpeed#=0
YSpeed#=0

[During Loop]
If Spacekey()=1 and Xspeed#=0 and YSpeed#=0
XSpeed#=rnd(5)-2.5
YSpeed#=rnd(3)+2
Endif

Position Object BallObj,Object Position X(BallObj)+XSpeed#,Object Position Y(BallObj)+YSpeed#,0

...and to make the ball bounce off objects just change the Xspeed# and YSpeed# or multiply them by -1 whenever they collide with the paddle, blocks, or walls...

well...I hope that helps...

The ball should only stop moving if you recent the move_flag somewhere. You'll have to find the angle of reflection. You would then rotate the ball to that angle, and continue moving.
