Up and down?
OK so, how do I make something go up and down? I can make them go right:
if Right key pressed
move 10 spaces
and left
if Left key pressed
move -10 spaces
but I cant make them go up or down! How do I do it!? HELP!

Re: Up and down?
quick tip about X and Y. X is the Horizontal movement of a sprite (left and right) changing it will make it go left or right (positive right negative left). They Y is the vertical movement (up and down) positive up negative down. Moving steps is going in the direction that the sprite is pointing at.

You don't actually need the stop script blocks, but that would be how you do it.
I'm taking a break from Scratch until 2.0 comes out. Any messages sent between then and now probably won't be read - sorry.

Re: Up and down?
no. The above should NOT be done. This is completly incorrect scripting. the when X key pressed script head is used for things such as typing, as it works simaler (has a delay before looping). I'll quickly make a flash project with these two to show how it works.

http://spamtheweb.com/ul/upload/020309/52103_Event_Head_loop_example.php
All you need to know in this example is that event head method is the one above and loop is one that looks like this
<when green flag clicked>
<forever>
<if>(Key right is pressed)
<change x by( 4 )
<end>
<if>(Key Left is pressed)
<change x by( -4)
<end>
<end>
