Now when I hit spacebar it will go left or right, I want the ball to go straight first time.Then when the ball hit a wall, block or line after that I want the ball to go random directions with "-1" somehow. This is my first school game project, it's a one line pong game.
Edit: Edit I've added "boll_speed.X = random.Next(-1, 1);", and that works perfectly!

Having trouble with these parts:
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
Exit();
if (Start == true)
{
boll_rect.X += (int)boll_speed.X;

}
if (boll_rect.X > Window.ClientBounds.Width - boll_texture.Width || boll_rect.X < 0)
boll_speed.X *= -1;
if (boll_rect.Y > Window.ClientBounds.Height - boll_texture.Height || boll_rect.Y < 0)
boll_speed.Y *= -1;
else if (ks.IsKeyDown(Keys.Space))
{
Start = true;
}
if (linje_rect.Intersects(boll_rect))
{
boll_speed.Y *= -1;
boll_speed.Y += random.Next(-100, 101) / 100.0f;
boll_speed.X *= -1;
boll_speed.X += random.Next(-100, 101) / 100.0f;
}
I'm thinking you mean you want the ball to change directions randomly when it hits the window boundaries or line. If so:
You're using constant values for your direction changes. Add a randomizer to multiply your boll_speed by.
For example, in pseudocode, instead of -1, do random(-1).
