Are you using DB or DBP? If you are using DBP then the commands are in the commands->sprites-> section of the help file. But I'll post the syntax here anyway. Also if you do the "sprite" command correctly it can be seemless movement, not "jumpy".
move sprite syntax:
MOVE SPRITE Sprite Number, Velocity
rotate sprite syntax:
ROTATE SPRITE Sprite Number, Angle
Here is a little snippet from my Breakout Clone that I made in DBP that uses the "sprite" command to move the paddle left and right on the screen.
rem Paddle Control
_control_paddle:
rem Left and Right keys move paddle
if leftkey() then paddleXleft = 10
if rightkey() then paddleXright = 10
rem Up key detaches ball
if upkey() then attached = 0
return
rem Update Paddle
_update_paddle:
rem Hopefully smoother paddle animation
if paddleXleft > 0
paddleX = paddleX - 3
rem Stop at left screen boundary
if paddleX < leftbound then paddleX = 0
cls
sprite paddleSnum, paddleX, paddleY, paddleInum
rem Move ball with paddle if its currently attached
if attached = 1
ballX = paddleX + 45
sprite ballSnum, ballX, ballY, ballInum
endif
dec paddleXleft
endif
if paddleXright > 0
paddleX = paddleX + 3
rem Stop at right screen boundary
if paddleX > rightbound then paddleX = rightbound
cls
sprite paddleSnum, paddleX, paddleY, paddleInum
rem Move ball with paddle if its currently attached
if attached = 1
ballX = paddleX + 45
sprite ballSnum, ballX, ballY, ballInum
endif
dec paddleXright
endif
return
Hope this helps.
