Worm Select in my program? (A easy way?)

So I'm would like to have a selection thing like the one that the worm program has! Before I have used local bla = read() and then had a number to select but I want to get a little bit more advance! Is there a way to make something like this that dont take up tons of place with code? I have seen some examples but that havn't really worked…

Tnx!

//Elis

take a look at my menu functions in my sig. you would want the basic menu example, no scrolling or anything

Well, it's basically a while true do with an os.pullEvent() (waiting for the key event) until enter is pressed.
Something like this? If you need me to explain anything, ask away :)/>/>/>

screenX, screenY = term.getSize()

t = {
	colSel = colours.yellow,
	colNotSel = colours.lime,
	difficulties = {
		{ text = "Easy", diffLevel = 1, diffSpeed = 1 },
		{ text = "Medium", diffLevel = 2, diffSpeed = 0.5 },
		{ text = "Hard", diffLevel = 3, diffSpeed = 0.1 }
	}
}

function getDifficulty()
	local sel = 1 -- define which option is selected by default
	while true do
		for i = 1, #t.difficulties do
			term.setCursorPos(math.floor((screenX-#t.difficulties[i].text)/2), math.floor(screenY/2) - 1 + i)
			term.setTextColour(i == sel and t.colSel or t.colNotSel)
			write(t.difficulties[i].text)
		end
		_, key = os.pullEvent("key")
		if key == keys.down and sel < #t.difficulties then
			sel = sel + 1
		elseif key == keys.up and sel > 1 then
			sel = sel - 1
		elseif key == keys.enter then
			return t.difficulties[sel].text, t.difficulties[sel].diffLevel, t.difficulties[sel].diffSpeed
		end
	end
end

term.clear()

difficulty, level, speed = getDifficulty()

term.clear()
term.setCursorPos(1, 1)
term.setTextColour(colours.yellow)

print( "You chose the difficulty '" .. difficulty .. "' which has the difficulty level of " .. level .. " and speed of " .. speed .. ".\n\nGoodluck!\n" )

term.setTextColour(colours.white)

Yes, that is what I want! Now, how can I change this so it starts new functions or programs instead of printing what difficulty I choosed and can I add more?
I havn't looked much into the code yet but I will soon, just thought I could ask now to maybe save some time :P/>

Hmm, how do you mean? So it brings up the list of certain programs and clicking enter will run them?

Well, using fs.list("/") will give you a table with all programs and directories of the computer (excluding rom) in which you can print that list and then clicking enter will run it using shell.run("program")

It is my personal opinion that one should not be dabbling in code that they do not wish to learn for themselves in order to reap the benefits of gratification.

EDIT:
By this I mean that if you aren't taking the time to understand what you're working with, you shouldn't be working with it.

A very true statement… some people seek gratification though and I suppose if that is what they want I wouldn't stop them

Well, I try to take my time to learn and understand but sometimes you need a little push to get going!
