1. string.explode works same as PHP's explode but parameters are reverted (PHP: explode - Manual)

Example:

local someString = "a,b,c,d"
local t = string.explode(someString, ",")
print(t[1]) -- a
print(t[3]) -- c

2. Text from talkactions is hidden by default? Try using return TRUE/FALSE at bottom (There is difference between TFS 0.3 and other distibutions)

3. doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_RED)

oh,Thx a lot,but i rlly can't understand nothng from that link you gave strange language

 

[Doggynub]

can you show me how to make parameter if the script is like !buy in one script it buy aol shovel

 

[slaw]

local items = {
	['aol'] =		{cost = 30000,	id = 2173},
	['backpack'] =	{cost = 100,	id = 1988},
	['rope'] =		{cost = 50,		id = 2120},
	['shovel'] =	{cost = 50,		id = 2554}
}

function onSay(cid, words, param, channel)
	if(param == '' or isInArray({'list', 'items'}, param:lower())) then
		local str = ""
		for name, options in pairs(items) do
			str = str .. "\n" .. name
		end

		doPlayerPopupFYI(cid, "Shop command - !buy\n\nItems:" .. str)
	end

	local item = items[param]
	if(item ~= nil) then
		if(not doPlayerRemoveMoney(cid, item.cost)) then
			doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "Sorry, you dont have enough money (" .. param .. " cost " .. item.cost .. ")")
			return true
		end

		local amount = item.amount and item.amount or 1
		doPlayerAddItem(cid, item.id, amount)
		doSendMagicEffect(getCreaturePosition(cid), CONST_ME_GIFT_WRAPS)
	end

	return false
end

Usage: !buy shovel, !buy aol, !buy list (Show list with items possible to buy)

 

[Doggynub]

ye it's is nice but can you explain now (just if you had time).

 

[Doggynub]

and what is nil
why you wrote this like that

local amount = item.amount and item.amount or 1

not that

local amount = item.amount

 

[chojrak]

@up:

local amount = item.amount and item.amount or 1

Means if not amount then amount = 1



About nil:

Point 2.2

 

[Doggynub]

thx.

 

[Doggynub]

oh,another thing why you ended by return false not true?

 

[chojrak]

return false

- player will say words.

return true

- player will not say words.

 

[Doggynub]

oh yea forgot lol ,Thx for fst reply.
