How to move a sprite up and then down without any key press?

2

How are you rendering it now?

3

Use a variable for Y.Pos and modify it?

Use the delta time property in Update to move it however you like over time by changing the position property you pass to spritebatch.draw().

If you’re talking about making the sprite move constanty up and down inside an specific range maybe you could try something like this in your Update:

float yPos = 0f;
float yOrigin = 0f;
float range = 5f;
float speed = 1f;
yPos = yOrigin + range * Math.Sin(speed * 2 * Math.PI * gameTime.ElapsedGameTime.TotalSeconds);

I haven’t tested it myself but hope it helps.
