Scratch

Well the walls part is going to be a bit trickier. Either your going to need a sensor (nice article), or complications in your script. Now, for your gravity would you like to see the simpler method or the more complex that's also more realistic?

With regards,

Okay, seeing as you are new, I'll get you the simpler method, though I have on last quick question; do you have any ceilings in your game I'm asking this because if I don't know this, then I might not get you the best script.

Okay, so that's going to complicate things, and it's going to be best for to use the more advanced method. Now, you'll need to replace your jumping/falling script(s) with this:

when gf clicked
set [Y Velocity v] to (0)
forever
 if <<([up arrow v] key pressed?) and <(Y Velocity) = (0)>> and (touching [ground/ceiling color]?)>//The jumping part
  set [Y Velocity v] to (7)//Jump strength
 else
  if (touching [ground/ceiling color]?)
   if <(Y Velocity) > (0)>//Detects floors and ceilings
    set [Y Velocity v] to ((0) - (Y Velocity))//Ceiling
   else
    set [Y Velocity v] to (0)//Floor
   end
  else
   if <(Y Velocity) > (-5)>//Maximum falling speed
   change [Y Velocity v] by (-.5)//Gravity
   end
  end
 end
 change y by (Y Velocity)
