I just starting learning XNA aswell, but I still have not figured out how to make my sprite move using the keypad of my keyboard. I know how to load the sprite and I know how to draw it to the screen. Can anyone help please?
Much like how to jump, creating the Platformer Starter Kit will show you how to move a sprite across the screen. To create the Platformer starter kit, create a new project, under the XNA category, you should see "Platformer Starter Kit" which will create a game with a name of "Platformer1".
Looking at this game, the one part that might confuse someone new to XNA is the Level, the Animation and the Animation Classes. You can pretty much ignore these and move right to the Player class (Player.cs) and start there. I beleive there is a "HandleInputs()" method which the game uses to figure out if a movement key is pressed.
From there, what I'd do is also open your current project (the one where you loaded a sprite but can't make it move) and start editting that project. If you only care about left and right (which is a good place to start), you really should only care about your sprites current Position (a 2D vector) and it's velocity (another 2D vector) which you will use in conjuncture with the GameTime to establish the new postion of the sprite prior to it being redrawn later in the frame.
Once you get that moving left and right, you can start implementing more of the Platformers code into your own project. Personally, I'd wouldn't worry about animating your sprites until you have basic movement and collision detection implemented.
