Here are my favorite jumping scripts:

1: This is the simplest script I know that still works well.

when green flag clicked
forever
    
if <touching [ground v]?> then
    
if <key [up arrow v] pressed?> then
repeat (20)
change y by (5)
    
end
    
end
else
change y by (-5)
end
end

2: This is a slightly more complex version that uses variables:

when green flag clicked
forever
    
if <touching [ground v]?> then
set [yv v] to [0]
change y by (5)
if <key [up arrow v] pressed?> then
set [yv v] to [10]
change y by (yv)
end
else
change [yv v] by (-0.5)
change y by (yv)
end
    
end
end

This gives a more realistic parabolic jump, but sinks into the ground on landing and tends to cause slight bouncing.

3: Here's my personal favorite jumping script, thanks to the impressive cobraguy. Take a look at him sometime; he does some great stuff!

change [yv v] by (-0.5)
change y by (yv)
if <<touching [ground v]?> and <key [up arrow v] pressed?>> then
    
set [yv v] to [8]
end
if <touching [ground v]?> then
change y by ((yv) * (-1))
set [yv v] to [0]
    
end
end

Hope this helps!
