Help with NPCs and sorting values in LUA

[Summ]

Hello
I have some nice ideas, but I need some functions/help..

1. How can I make a NPC say something if someone enters the screen?
It somehow possible with onThink functions? Please post a example.

2. If I got some numbers how I can make a ranking?

one = getPlayerStorageValue(cid,1001)
two = getPlayerStorageValue(cid,1002)
three = getPlayerStorageValue(cid,1003)
...
twenty = getPlayerStorageValue(cid,1020)

How can I make it so the script gets the values and sorts them from highest to the lowest?

BUMP

Please I need help ...

1. onCreatureAppear()

 

[Summ]

And how do I make it that it only says it to one person each 20 secs and not if the player leaves the screen for 2 sec and comes again?

No one can help me with the second question??
It's important..

About sorting, you can pack all these values into table and use table.sort

for example:
local t = {}
table.insert(t, 3)
table.insert(t, 400)
table.insert(t, 7)
table.insert(t, 1)
table.sort(t, function(a, b) return a > b end)

t[1] -- your highest value
t[#t] -- your lowest value

if you want from lowest to highest just change in this part - a > b to <


second way is normal if statement if you don't have much numbers
