doInArea

How to use function??
doInArea(pos,radius,luaString,var)

this not work:

function onUse(cid, item, fromPosition, itemEx, toPosition)
AREA_WAVE4 = {
	{1, 1, 1, 1, 1},
	{0, 1, 1, 1, 0},
	{0, 1, 1, 1, 0},
	{0, 0, 3, 0, 0}
}

doInArea(AREA_WAVE4, 1, doSendMagicEffect(), var)
	return true
end

How to make function getCreaturesFromArea

area = {
	{1, 1, 1, 1, 1},
	{0, 1, 1, 1, 0},
	{0, 1, 1, 1, 0},
	{0, 0, 3, 0, 0}
}
creatures = getCreaturesFromArea(area, fromPosition)

		for i, v in ipairs(creatures) do
			if isPlayer(v) then
				doCreatureSay(v, "i am player")
			else
				doCreatureSay(v, "i am not player")
			end
		end

Area is central position I guess and radius is sqms to left/right/up/down.
LuaString hmm, function?
Var hmm, parameters?

 

[Dominik ms]

But how in practice??

 

[chojrak]

No idea, is it even official function?

 

[Dominik ms]

No, it is from otal v 1.3

 

[chojrak]

So just ask in official thread?

 

[Dominik ms]

Okay, but strongly i need script getCreaturesFromArea, have any idea??

 

[chojrak]

local creatures = getCreaturesFromArea({x = 100, y = 100, z = 7}, {x = 200, y = 200, z = 7}) -- from / to
for _, creature in ipairs(creatures) do
	doCreatureSay(creature, isPlayer(creature) and "I'm player" or "I'm not player", TALKTYPE_SAY)
end

What about this one? And again, I'm guessing parameters. ;p

doInArea its sux.
doInArea(pos,radius,luaString,var)-- by Mock
Better use:
executeInArea(pos, area,cmd,...)

--executeInArea(pos, area,cmd,...)
function onUse(cid, item, fromPosition, itemEx, toPosition)
AREA_WAVE4 = {
    {1, 1, 1, 1, 1},
    {0, 1, 1, 1, 0},
    {0, 1, 1, 1, 0},
    {0, 0, 3, 0, 0}
}

    doInArea(toPosition,AREA_WAVE4,function(pos,var) doSendMagicEffect(pos,var) end, 1)
    return true
end

 

[Dominik ms]

hmm, can i get monster uid with this function??

 

[Dominik ms]

Refresh, how to get All Creatures From Area??

 

[Summ]

I wrote a function + example.
Rep++

function getAreaCreatures(from, to, check)
	local creatures = {}
	for x = from.x, to.x do
		for y = from.y, to.y do
			for z = from.z, to.z do
				local p = getThingFromPos({x=x,y=y,z=z, stackpos=STACKPOS_TOP_CREATURE})
				if check(p.uid) then table.insert(creatures,p.uid) end
			end
		end
	end
	return creatures
end

local m = getAreaCreatures({x=1,y=1,z=7}, {x= 50,y=50,z=7}, isMonster)
for _, uid do
  -- do something with uid of monsters..
end

getAreaCreatures(fromposition_in_table, toposition_in_table, function_to_check)
function_to_check can be:
isCreature, isMonster, isNpc, isPlayer

AREA_WAVE4 = {
{1,1,1,1,1},
{0,1,1,1,0},
{0,0,3,0,0}
}
Thx, i have code like this, but not work for area...:'(

 

[Cykotitan]

You can't use it with areas like that.

 

[Dominik ms]

oh yes, stackpos is blocking ):
