Scratch

That's quite easy to do, using the "pick random" block and knowing exactly what you want to do. c:

We have three options for altitude: Low, medium and high. So, the "pick random" block must pick between these three options, as numbers.

when I receive [fly v]
set [option v] to (pick random [1] to [3])
if <(option) = [1]> //low altitude
    set x to [-50]
end
if <(option) = [2]> //medium
    set x to [0]
end
if <(option) = [3]> //high
    set x to [50]
end

To make the script wait a random time, it's as simple as using the same "pick random" block as the parameter of a "wait" block, with the values you find appropriate:

when I receive [start level v]
forever //or until the level ends
    broadcast [fly v]
    wait (pick random [1] to [20]) secs
end

Edit:

I am new to scratch, but do know the core principles of programing.
I needed to know how to use random, and you helped me see how, thanks!

Glad to hear that c: Have you used any other programming language, before Scratch? Just curious 

Hi,

To technoguyx:

I am currently learning Java, so kind of. 

To olayemi2003:

What exactly do you mean? Please clarify.

Are you asking if you can make several sprites and then piece them together?

No,i mean how do we let  the part of the body of sprite move like the hand ,leg ,head  and other parts of the body

Well if you want to do that, you're either going to need to create multiple costumes, or you'll have to turn the body part in question into a new sprite so that you can manipulate it.

I hope that this answers your question! Also, hello olayemi2003 and welcome to Scratch! I wish you much new found wisdom in the coming days!

Hi,

olayemi2003,
Costumes are all within a sprite, they are created and edited in the "Costumes" tab, which is located besides the "Scripts" tab which is near the top of the screen.
They are like different poses in one sprite.

I believe, if you wanted to, make several sprites separately and then have them track to each other... I think, don't quote me on that... Like having the "arm" track to the "Body", though I've not tried that yet...

I hope that helped,

P.S. I'm working on a project right now, but after wards if you'd like i could try to implement that theory about the multiple sprites.
