Platform Script Jump Help

I need help with a platform script. I would want to move left and right while jumping.
I tried this but it didn't work:
when I receive [message1 v]
switch costume to [costume1 v]
go to x: [-226] y: [-92]
show
forever
if <key [left arrow v] pressed?> then
move [-3] steps
if <key [up arrow v] pressed?> then
change y by [30]
set [ypos v] to (y position)
set [xpos v] to (x position)
change [ypos v] by [-30]
glide [0.5] secs to x: (xpos) y: (ypos)
end
end
if <key [right arrow v] pressed?> then
move [3] steps
if <key [up arrow v] pressed?> then
change y by [30]
set [ypos v] to (y position)
set [xpos v] to (x position)
change [ypos v] by [-30]
glide [0.5] secs to x: (xpos) y: (ypos)

there is a much simpler way.
when [up arrow v] key pressed
change y by (30)
wait (0.1) secs
change y by (-30)

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!
when green flag clicked
forever

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!

if <(platypus) = [platypus]> then
set [platypus v] to [platypus]

Then I can't move while in air.

The first one helped but the rest crashed my browser and didn't save which I didn't care. Thanks
