So you want a bouncing script that would mimic what the edge would normally do?  Is your sprite using direction or x and y velocities?

DIRECTION

when gf clicked
forever
   move (x) steps
   if <touching [big sprite v] ?>
      if <([abs v] of (x position)) > [200]>
         point in direction ((direction) * [-1])
      else
         point in direction ((((direction) - (90)) * (-1)) + (90))
      end
   end
end

when gf clicked
forever
   change x by (x velocity)
   change y by (y velocity)
   if <touching [big sprite v] ?>
      if <([abs v] of (x position)) > [200]>
         set [x velocity v] to ((x velocity) * (-1))
      else
          set [y velocity v] to ((y velocity) * (-1))
      end
   end
end

Here is a slightly fixed version of AtomicBawm3's scripts:

DIRECTION

when gf clicked
forever
   move (x) steps
   if <touching [big sprite v]?>
      if <([abs v] of (x position)) > (200)>
         point in direction (<direction> * (-1))
      else
         point in direction (<<<direction> - (90)> * (-1)> + (90))
      end
   end
end

when gf clicked
forever
   change x by (x velocity)
   change y by (y velocity)
   if <touching [big sprite v]?>
      if <([abs v] of (x position)) > (200)>
         set [x velocity] to <(x velocity) * (-1)>
      else
          set [y velocity] to <(y velocity) * (-1)>
      end
   end
end

X, Y VELOCITIES

when gf clicked
forever
   change x by (x velocity)
   change y by (y velocity)
   if <touching [big sprite v]?>
      if <([abs v] of (x position)) > [200]>
         set [x velocity v] to ((x velocity) * (-1))
      else
          set [y velocity v] to ((y velocity) * (-1))
      end
   end
end

Fixed scripts.

Try this script:

when gf clicked
forever if <touching big sprite>
point in direction <pick random (0) to (360)>
end

Try this script:

when  clickedforever if touching big spritepoint in direction pick random 0 to 360

Well, first, you would have to add a move block and second, random direction means it can continue moving into the big sprite.


Well, I don't think it works
