hello every body..
i am trying to make ship shoot bullet and laser..
this my code:

 public readonly static TimeSpan delay = new TimeSpan(0, 0, 0, 0, 330);
        private TimeSpan lastupdate1;
        private TimeSpan lastupdate2;
        // bullet
        public Texture2D pelurutexture;
        //laser
        public Texture2D lasertexture;

public void control(GameTime GT)
        {
            if ((Keyboard.GetState().IsKeyDown(Keys.Space) || (Keyboard.GetState().IsKeyDown(Keys.RightShift))))
            {
           if (Keyboard.GetState().IsKeyDown(Keys.Space)  && (lastupdate1 > delay))
            {
                flys[0].shoot();
              
                lastupdate1 = TimeSpan.Zero; 
            }
         else if (Keyboard.GetState().IsKeyDown(Keys.RightShift) && (lastupdate1 > delay))
            {
                flys[0].shoot2();
                lastupdate1 = TimeSpan.Zero;
            }
            }
            else  if (Keyboard.GetState().IsKeyDown(Keys.Space) && (Keyboard.GetState().IsKeyDown(Keys.RightShift)&& (lastupdate1 > delay)))
            {
                flys[0].shoot();
                flys[0].shoot2();
                lastupdate1 = TimeSpan.Zero;
            }
          
        }

if i click space, it will shoot bullet, if i clik shift, it will shoot laser.. but i can not shot 2 kind like laser and bullet at same time..
if i click space and shift together, it only shoot bullet, how to make it can shoot together ya?
thx..

I doubt this works:

if (Keyboard.GetState().IsKeyDown(Keys.Space) && (Keyboard.GetState().IsKeyDown(Keys.RightShift)&& (lastupdate1 > delay)))
{

More likely (but I don't do XNA) is that the IsKeyDown returns multiple values that have been OR'd together. So you need to check in the same way. Something like

if (Keyboard.GetState().IsKeyDown(Keys.Space | Keys.RightShift))
{
  // then do something
}

But that is a guess based on other C# experience

thx for replying..
do u mean like this?

   if (Keyboard.GetState().IsKeyDown(Keys.Space | Keys.RightShift))
            {
                if (Keyboard.GetState().IsKeyDown(Keys.Space) && (lastupdate1 > delay))
                {
                    flys[0].shoot();

                    lastupdate1 = TimeSpan.Zero;
                }
                if (Keyboard.GetState().IsKeyDown(Keys.RightShift) && (lastupdate1 > delay))
                {
                    flys[0].shoot2();
                    lastupdate1 = TimeSpan.Zero;
                }
            }
              if (Keyboard.GetState().IsKeyDown(Keys.Space & Keys.RightShift) & (lastupdate1 > delay)) 
                {
                    flys[0].shoot();
                    lastupdate1 = TimeSpan.Zero;
                    flys[0].shoot2();
                    lastupdate1 = TimeSpan.Zero;
                }

it can not shoot 2 type directly too..

You should be able to accomplish this with a couple of if checks. The following code assumes that shoot() is the method you're using for firing bullets and shoot2() is the method for firing lasers.

KeyboardState keyState = Keyboard.GetState();

if (keyState.IsKeyDown(Keys.Space))
{
    if (lastUpdate1 > delay)
    {
        flys[0].shoot();
    }
}

if (keyState.IsKeyDown(Keys.LeftShift) || keyState.IsKeyDown(Keys.RightShift))
{
    if (lastUpdate1 > delay)
    {
        flys[0].shoot2();
    }
}

Also, can I get someone to throw this over to the XNA section?

With the Update method executing 60 times per second, the code would be executed so fast that it would appear as though they were both shooting at the same time, even if they are two separate events.

thx bro.. it almost work. now my code like this:

if (Keyboard.GetState().IsKeyDown(Keys.Space))
            {
                if (lastupdate1 > delay)
                {
                    flys[0].shoot();
              
                }
            }
            if (Keyboard.GetState().IsKeyDown(Keys.RightShift))
            {
                if (lastupdate1 > delay)
                {
                    flys[0].shoot2();
                    lastupdate1 = TimeSpan.Zero;
                }
            }

if click left shift it will shoot laser, then i click space, it can shoot bullet together with laser in delay time..
but if i ho;d the space , it shoot bullet many ammount.. not get delay time.. so i add code "lastupdate1 = TimeSpan.Zero;"
to

if (Keyboard.GetState().IsKeyDown(Keys.Space))
            {
                if (lastupdate1 > delay)
                {
                    flys[0].shoot();
                    lastupdate1 = TimeSpan.Zero;
                }
            }

the result will be can not shoot bullet and laser in same time.. so how to make that bullet can got delay time too?
thx..

Why not have a TimeSpan lastupdate1 for bullets and a separate TimeSpan lastupdate2 for lasers? This way both can work at the same time irrespective of their own unique delays?

now i have got true answer from forums msdn, using coding like this:

   if (lastupdate1 > delay)
            {
                if (Keyboard.GetState().IsKeyDown(Keys.Space))
                {
                    flys[0].shoot();
                    lastupdate1 = TimeSpan.Zero;
                }
            }
            if (lastupdate2 > delay)
            {
                if (Keyboard.GetState().IsKeyDown(Keys.RightShift))
                {
                    flys[0].shoot2();
                    lastupdate2 = TimeSpan.Zero;
                }
            }

thx very much..
