the problem is that every time I get my sprite to bounce off a wall the sound effect only plays on the very bottom and the very right ( I need it to play on the top bottom left and right ). look at the code and see if you can find any errors.
note: space1.Play is the command to make the space sound effect play.
Code: Select all
int MaxX = graphics.GraphicsDevice.Viewport.Width - mSprite.Texture.Width ;
int MinX = 0;
int MaxY = graphics.GraphicsDevice.Viewport.Height - mSprite.Texture.Height ;
int MinY = 0;
if (mSprite.Position.X > MaxX)
{
mSprite.Speed.X *= -1;
space1.Play (mSprite.Position.X = MaxX);
}
else if (mSprite.Position.X < MinX)
{
mSprite.Speed.X *= -1;
space1.Play (mSprite.Position.X = MinX);
}
if (mSprite.Position.Y > MaxY)
{
mSprite.Speed.Y *= -1;
space1.Play (mSprite.Position.Y = MaxY);
}
else if (mSprite.Position.Y < MinY)
{
mSprite.Speed.Y *= -1;
space1.Play (mSprite.Position.Y = MinY);
