Hello,

I am struggling to find a way to draw a line of bricks and to create collision detection between the bricks and the ball.

Any help / suggestions are much appreciated.

Cheers,

Create a Brick class that can draw itself at a given location. Keep a list of all bricks and their position on screen. Do similar with the ball, and as it moves check whether its edge touches the edge of any brick.

If you are using Windows Forms then you may start simply drawing rectangles as bricks and a circle as the ball (then you might refine your graphics).
Collision detection is actually very simple: let {XC, YC} be the coords of center of the ball, R is ray, and {XTL,YTL}, {XBR, YBR} respectively, the top-left and bottom-right point of a brick, then

C#

if ((XTL-XC) < R || (XC-XRB) < R || (YTL-YC) < R || (YC-YBR) < R)
{// handle collision here
}

detects a collision.
