Scratch

I don't know of any good way to do it without bouncing. 
What I do is have two personal (for this sprite only) variables, called "last xpos" and "last ypos".
Then, in my moving script, I have this:

when gf clicked
forever
   set [last xpos v] to (x position)
   set [last ypos v] to (y position)
   moving script
   if <touching color [#000000]?> //use the color you don't want to go through
      go to x: (last xpos) y: (last ypos)
   end
end

I do something similar, but with the x-change and y-change separate, so if you, say, jump into a ceiling, your horizontal movement isn't affected.

when gf clicked
forever
set[old_x] to (x position)
set[old_y] to (y position)
x-movement-script
if<touching [wall/ceiling]?>
set x to (old_x)
end
y-movement-script
if<touching [wall/ceiling]?>
set y to (old_y)
end
end

you could have a special collision sprite for the main character, so if one point of the collision box is touching the collision object the character will stop moving.
