Scratch

Basic method:
Put this in the sprite that you want to move.


<when green flag clicked>
<forever>
  <if><key[ left arrow ]pressed?>
  <change x by( -3 )
  <end>

  <if><key[ right arrow ]pressed?>
  <change x by( 3 )
  <end>
<end>

Basic method2:

This gives a sprite a velocity effect

make a variable called "xvelocity"

<when green flag clicked>
<forever>
  <set x to( <{ xvelocity }> )
  <set{ x velocity  }to( (( <{ xvelocity }> <*> .95 ))
  <if><key[ right arrow ]pressed?>
     <change{ xvelocity }by( .3 )
  <end>
  <if><key[ left arrow ]pressed?>
  <change{ xvelocity }by( -.3 )
  <end>
<end>
