Scratch

My class is in the middle of creating scratch games. The problem we have right now is that a student has a sprite that he wants to climb over a stone, say it is a black color and the sprite is a grey color. Is there an easy script to get it to stay on the black instead of bouncing off of it?

<when green flag clicked>
<forever>
<if><touching color[ black
<repeat until><<  <not> <touching color[ black >>
<change y by( 1
<end>
<end>
<end>

should work. I have a second, more advanced platformer engine if you want.

and if the ground is, let's say, brown, this would be a good script for the sprite:

<when green flag clicked>
<forever>
<if><< <touching color[ brown <and> <<  <not> <key[ up arrow ]pressed?> >> >>
<set y to( <y position>
<else>
<if><<  <not> <touching color[ brown >>
<change y by( -1
<if> << <touching color[ brown <and> << <key[ up arrow ]pressed?> >> >>
<repeat( 150
<change y by( 1
<end>
<repeat( 150
<change y by( -1
<end>
<end>
<end>

this would be if the up arrow was used to jump. Sorry about the unaligned scripts for this one, just do it like you normally would on scratch.
