Re: Bounce back, black!
How you bounce depends on how you move. There are several standard ways to move around in scratch, and each results in a different way of bouncing.

Re: Bounce back, black!
The best way is [blocks]<point in direction( (( 180 <-> <direction> ))[/blocks], because most ways use that, even though not many people know about it.
Under the sprite that's supposed to bounce, put this script in:
<when green flag clicked>
<forever>
<if><touching color[ black
<point in direction( (( 180 <-> <direction> ))
<end>
<end>
That *should* work.

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.

Put a
Wait until not touching black
block after the direction block, or you will get stuck.

its not as easy as that! that only works for up and down movement. I made a project with full bouncing ability:
