How to make smooth Character movement

[Ultimasnake]

At the momen i am just moving my players X Y and Z axis 1 point (whatever) at a time when i press left and right , jumping looks good up to now.. but making a left/right movement looks crappy (also no animation but that is a second thing to do) how can i make a nice way to move my character?

I usually use acceleration and deceleration.

The character starts moving 1 pixel, and gains speed as he moves until reaching a final speed. deceleration is a bit trickier since you dont want it to affect the gameplay too much.

you could make the frames interpolate...
like this:
X = (X1 + X2) / 2

it gets the X position in between the two frames...
