Function Documentation

void ball (  )

Ball.

Move the ball

2-step movement for the ball - combines moveBall1() and moveBall2() with setAngle() and doBricks() to ensure game updates properly.

NB: wait() functions were included to slow down the motion of the ball to a reasonable speed. A timer would have been preferable but the game ceased to function if this implementation was used.

Definition at line 932 of file BrickBreaker.cpp.

void borderInit (  )

Initialise the Borders.

Draws the boundaries so that the ball cannot leave the screen through the sides or top. Also draws some graphics for containing the scores and remaining lives.

Definition at line 1112 of file BrickBreaker.cpp.
