Scratch

Create a variable named yVelocity.  Add this script to your program:

when gf clicked
forever
if  < key [up arrow v] pressed? >
set [yVelocity v] to [4] // choose a value for the height of the jump
wait until <not<key [up arrow v] pressed?>>
end
end

when gf clicked
forever
change y by (yVelocity)
change [yVelocity v] by (-0.3) // choose a value for the strength of gravity
if <touching [ground v]?>
change y by ((-1) * (yVelocity))
set [yVelocity v] to [0]
end
end

Added a conditional to prevent a glitch. I also fixed your forever loops.

...?

This is the translated version from Google Translate:

Hello, I was making a game and when I'm done and have discussed the change of character is randomly changed me. [removed as it is some unknown text.]!!

That random text actually means "Help me!!!"

Oh. Anyway, (s)he should have posted it in the Language forums.
