Guys,

How would I make a spell to create an item around the player without it being inside pz area, walls, monsters, players or obstacles?

I created a script but it does not respect the conditions as I said.

C++: 
function onCastSpell(creature, variant)
local player = Player(creature)

    local nivel = player:getLevel()
    local ml = player:getMagicLevel()
    -- if ml >= 1 and nivel >= 3 then
   
    local player = Player(creature)
    local target = player:getTarget()
    local alvo = target:getDirection()
    local alvopos = target:getPosition()
    local playerdir = player:getDirection()
    local playerpos = player:getPosition()
   
   
    local nortepos = Position(target:getPosition().x, target:getPosition().y - 1, target:getPosition().z)
    local nortepos2 = Position(target:getPosition().x + 1, target:getPosition().y - 1, target:getPosition().z)
   
    local lestepos = Position(target:getPosition().x + 1, target:getPosition().y, target:getPosition().z)
    local lestepos2 = Position(target:getPosition().x + 1, target:getPosition().y +1, target:getPosition().z)
   
    local sulpos = Position(target:getPosition().x, target:getPosition().y + 1, target:getPosition().z)
    local sulpos2 = Position(target:getPosition().x - 1, target:getPosition().y + 1, target:getPosition().z)
   
    local oestepos = Position(target:getPosition().x - 1, target:getPosition().y, target:getPosition().z)
    local oestepos2 = Position(target:getPosition().x - 1, target:getPosition().y - 1, target:getPosition().z)
   
   
    Game.createItem(6972, 1, sulpos2)
    Game.createItem(6972, 1, sulpos)
    Game.createItem(6972, 1, lestepos2)
    Game.createItem(6972, 1, lestepos)
    Game.createItem(6972, 1, nortepos2)
    Game.createItem(6972, 1, nortepos)
    Game.createItem(6972, 1, oestepos2)
    Game.createItem(6972, 1, oestepos)

    sulpos2:sendMagicEffect(69)
    sulpos:sendMagicEffect(69)
    lestepos2:sendMagicEffect(69)
    lestepos:sendMagicEffect(69)
    nortepos2:sendMagicEffect(69)
    nortepos:sendMagicEffect(69)
    oestepos2:sendMagicEffect(69)
    oestepos:sendMagicEffect(69)
   
            item1 = Tile(sulpos2):getItemById(6972)
            item2 = Tile(sulpos):getItemById(6972)
            item3 = Tile(lestepos2):getItemById(6972)
            item4 = Tile(lestepos):getItemById(6972)
            item5 = Tile(nortepos2):getItemById(6972)
            item6 = Tile(nortepos):getItemById(6972)
            item7 = Tile(oestepos2):getItemById(6972)
            item8 = Tile(oestepos):getItemById(6972)
           
            if item1 and item2 and item3 and item4 and item5 and item6 and item7 and item8 then
                addEvent(function() item1:remove() end, 5000)
                addEvent(function() item2:remove() end, 5000)
                addEvent(function() item3:remove() end, 5000)
                addEvent(function() item4:remove() end, 5000)
                addEvent(function() item5:remove() end, 5000)
                addEvent(function() item6:remove() end, 5000)
                addEvent(function() item7:remove() end, 5000)
                addEvent(function() item8:remove() end, 5000)
               
                addEvent(function() sulpos2:sendMagicEffect(69) end, 3500)
                addEvent(function() sulpos:sendMagicEffect(69) end, 3500)
                addEvent(function() lestepos2:sendMagicEffect(69) end, 3500)
                addEvent(function() lestepos:sendMagicEffect(69) end, 3500)
                addEvent(function() nortepos2:sendMagicEffect(69) end, 3500)
                addEvent(function() nortepos:sendMagicEffect(69) end, 3500)
                addEvent(function() oestepos2:sendMagicEffect(69) end, 3500)
                addEvent(function() oestepos:sendMagicEffect(69) end, 3500)
            end
    return true

end

Infernum
Probably because the pos table is a reference + reused.
Use this instead:
LUA: 
function onCastSpell(creature, variant)
    local basePosition = creature:getPosition()
    -- get offsets for each direction from the player
    for dir, offset in pairs(Position.directionOffset) do
        local pos = Position(basePosition.x + offset.x, basePosition.y + offset.y, basePosition.z)
        local tile = Tile(pos)
        if tile and tile:isWalkable() then
            local item = Game.createItem(6972, 1, pos)
            pos:sendMagicEffect(CONST_ME_INSECTS)
            -- remove items in the future
            addEvent(function()
                local item = tile:getItemById(6972)
                if item then
                    item:remove()...

Try this?
This code should be MUCH faster as well in terms of performance.
LUA: 
function onCastSpell(creature, variant)
    local basePosition = creature:getPosition()
    local pos = Position(0, 0, basePosition.z)
    -- get offsets for each direction from the player
    for dir, offset in pairs(Position.directionOffset) do
        pos.x = basePosition.x + offset.x
        pos.y = basePosition.y + offset.y
        local tile = Tile(pos)
        if tile and tile:isWalkable() then
            local item = Game.createItem(6972, 1, pos)
            pos:sendMagicEffect(CONST_ME_INSECTS)
            -- remove items in the future
            addEvent(function()
                local item = tile:getItemById(6972)
                if item then
                    item:remove()
                end
            end, 5000)
            addEvent(Position.sendMagicEffect, 3500, pos, CONST_ME_INSECTS)
        end
    end
    return true
end

Add this inside of data/lib/core/tile.lua
LUA: 
function Tile.isWalkable(self)
    local ground = self:getGround()
    if not ground or ground:hasProperty(CONST_PROP_BLOCKSOLID) then
        return false
    end

    local items = self:getItems()
    for i = 1, self:getItemCount() do
        local item = items[i]
        local itemType = item:getType()
        if itemType:getType() ~= ITEM_TYPE_MAGICFIELD and not itemType:isMovable() and item:hasProperty(CONST_PROP_BLOCKSOLID) then
            return false
        end
    end
    return true
end

very good it work,

have 2 Details,

1 - the spell is to target

2 - this part addEvent(Position.sendMagicEffect, 3500, pos, CONST_ME_INSECTS) are only one wall with effect.
