Placing Sprites Dynamically At Different Time Increments

This is the second day I am going at this, and not getting anywhere. I need help.
I am trying to create a sprites at different places, but at different intervals. In other words, I don’t want them to appear all at the same time.

I already have their positions, it’s just a matter of placing them.
I just need a slight delay between each placement, but my efforts at doing this all fail, and I cannot find a single example on the internet.

            spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend);
            for (int i = 0; i < 111; i++)
                int n = 0;
                while (n < 30) { n += 1; } // fail
                xx = objPosX[aArray[i]]; yy = objPosY[aArray[i]];

                spriteBatch.Draw(obj[i], new Vector2(xx, yy), rect0,
                                    Color.Blue, 0.0f, Vector2.Zero, 1.0f, SpriteEffects.None, 0.1f);

…Appreciate any help in getting this done.

If they are all within the same draw call, they are all going to appear at the same point in time. If you want to draw some sprites during a certain frame, and other ones during a different period, you need to add logic to handle which are visible per frame and draw only those.

Thanks. Great idea. Got it working.
