This will help you make a Game or interactive Animation with the arrow keys.
X-Y Method
This is the easiest way to do this. First, go to the sprite you want to make move. Then add these scripts:
when [up arrow v] key pressed change y by (10) when [down arrow v] key pressed change y by (-10) when [right arrow v] key pressed change x by (10) when [left arrow v] key pressed change x by (-10)
Now, the sprite will stay in one direction while it moves around.
Steps Method
Using these scripts, the sprite will turn around while it moves. This is not recommended in a sprite that must turn for other reasons.
when [up arrow v] key pressed point in direction (0 v) move (10) steps when [down arrow v] key pressed point in direction (180 v) move (10) steps when [right arrow v] key pressed point in direction (90 v) move (10) steps when [left arrow v] key pressed point in direction (-90 v) move (10) steps
Now your sprite will turn when it moves. If you do not want the user to see it turn, add
when gf clicked set rotation style [don't rotate v]
If you only want the user to see it go left or right, add
when gf clicked set rotation style [left-right v]
