i writing program has ball moving around picturebox , have set of bricks @ top of picturebox. i have used array location of bricks using: int[,] bricklocation = { { 0, 0 }, { 30, 0 } } i have used drawrectangle construct each brick within picturebox. exist within timer1_tick event. ball drawn, picturebox cleared , x , y coordinate change. when ball "collides" brick, want way in brick disappear because there brick behind it. [brick0] [brick1] at moment, code collision between ball , brick1 is: if ((yball > bricky) && (yball < bricky + 25) && (xball > brickx) && (xball < brickx + 80)) { yballchange = -yballchange; } where xball, yball x , y coordinate of ball , brickx , bricky coordinate bricks. so when ball coordinates within bounds of brick1 y-direction change. is there way in can redraw [brick1] in new position no size eliminate there can collision between ball , [brick0]? o
