Uhh this may be a noob question but I am really stuck with this. How do I move the sprite left and right in 2d? I used dbMoveSprite to get it to move up and down, but i cannot figure out how to get the sprite to move left/right! Also, i have another problem besides this. I have a 480x480 bitmap for a backdrop. I loaded it and put in on the screen, but there was that little gap on the right side of the screen. So i tried to resize the window to 480x480 and it scaled the picture down! That gap is still there and the picture is just smaller width-wise. Any way to fix that? Thanks for your time.

You need to rotate it if the user presses the right or left arrow using



then you put in the movement code.

Or just use dbSprite() to position it where you want. But you'll need to keep track of it's co-ordinates.

RE: Sprite moving left or right....
there are 2 ways that I think i would try this first.. if using the dbMoveSprite commands... you would need to detect for the input, then once its detected, rotate the sprite 90deg left or right(provided its facing towards the top of the screen, dbMoveSprite will move a sprite FORWARD.. in the direction its facing, so if u want it to move left, rotate it to face left before moving), call dbMoveSprite with whatever params you like, then rotate the sprite back the way it should face... then draw the screen.... essentially you can do whatever you like to the sprites during the game loop, as long as they are where they should be before you draw the screen.... The second way of moving sprites around i would consider would be to simply dbPasteSprite or even use dbSprite() at the X,Y co-ords that i wanted it at in relation to the user input.

RE: The window sizing thing is because the area inside the window is whatever area you specify it to be.. ie 1024x768...1280x1024.. anything you load into that screen is scaled to whatever scale/resolution the screen is using in relation to its actual size... so loading the pic in with a screen at size X,Y and noticing it has a gap... then resizing the screen wont make the gap go away, as anything that is done to the screen, is done to anything that is inside the screen aswell... ie, when you resize the screen, you resize the pics inside it aswell....

Here you go:

The code from Clbembry, is alright too.. but i will give another example that also move down/up, which also checks for screen boundaries.
