Items drop on line

[Na 5tyk]

Hello. I have code:

    -- Rain item Events created by Maniucza (c) --
     
    local fromPos = {x=996, y=998, z=6}
    local toPos = {x=1004, y=998, z=6}
    local items = {{2667,1}, {2679,1}, {2671,1}, {2696,1}, {2689,1}}
    local maxItems = 20
     
    function isWalkable(pos, creature, proj, pz)
    if getTileThingByPos({x=pos.x,y=pos.y,z=pos.z}).itemid == 0 then return false end
    local n = not proj and 3 or 2
    for i = 0, 255 do
    pos.stackpos = i
    local tile = getTileThingByPos(pos)
    if tile.itemid ~= 0 and not isCreature(tile.uid) then
    if hasProperty(tile.uid, n) or hasProperty(tile.uid, 7) then
    return true
    end
    end
    end
    return true
    end
     
    function checkPositions(n)
	local pos = {x=math.random(fromPos.x,toPos.x), y=math.random(fromPos.y,toPos.y), z=math.random(fromPos.z,toPos.z)}    if isWalkable(pos, true, false, true) then
    return pos
    end
    return (checkPositions(n+1) or false)
    end

     
    function onSay(cid, words, param)
    doBroadcastMessage("Serek sie zaczal!", MESSAGE_EVENT_ADVANCE)
    return addEvent(spawnItem, 0, 1)
    end
     
    function spawnItem(created)
    if created >= maxItems then
    return doBroadcastMessage("", MESSAGE_EVENT_ADVANCE)
    end
    local itemPos, itemInf = checkPositions(1), math.random(#items)
    doCreateItem(items[itemInf][1], items[itemInf][2], itemPos)
    doSendMagicEffect(itemPos, CONST_ME_LOSEENERGY)
    return addEvent(spawnItem, 0, created+1)
    end

And I want to items drop in line but now drop random position (in line).

SS:
Good effect: (by me, no script)


Bad effect (by script, random postion):

local fromPos = {x=996, y=998, z=6}
local toPos = {x=1004, y=998, z=6}
local items = {{2667,1}, {2679,1}, {2671,1}, {2696,1}, {2689,1}}
local maxItems = 20

function isWalkable(pos, creature, proj, pz)

	if getTileThingByPos({x=pos.x,y=pos.y,z=pos.z}).itemid == 0 then
		return false
	end
	local n = not proj and 3 or 2
	for i = 0, 255 do
		pos.stackpos = i
		local tile = getTileThingByPos(pos)
		if tile.itemid ~= 0 and not isCreature(tile.uid) then
			if hasProperty(tile.uid, n) or hasProperty(tile.uid, 7) then
				return true
			end
		end
	end
	return true
end

function checkPositions(n)
	local pos = {x=(fromPos.x + n), y=(fromPos.y), z=(fromPos.z)}
	if pos.x > toPos.x then
		return false
	elseif isWalkable(pos, true, false, true) then
		return pos
	end

	return (checkPositions(n+1) or false)
end

function spawnItem(created)
	if created >= maxItems then
		return doBroadcastMessage("", MESSAGE_EVENT_ADVANCE)
	end
	local itemPos, itemInf = checkPositions(1), math.random(#items)
	doCreateItem(items[itemInf][1], items[itemInf][2], itemPos)
	doSendMagicEffect(itemPos, CONST_ME_LOSEENERGY)

	return addEvent(spawnItem, 0, created+1)
end

function onSay(cid, words, param)
	doBroadcastMessage("Serek sie zaczal!", MESSAGE_EVENT_ADVANCE)

	return addEvent(spawnItem, 0, 1)
end

but this is a bad script
