Lua Help in script

[Scremo]

well I made this script to randomly spawn an item checking some conditions, it turns out that when it can't spawn in the checked condition it just doesn't spawn, I wanted to know how I could make it check the position and if it couldn't generate a new position and then yes spawn the item.

function spawnItemOnArea(from, to, itemId, itemCount)    
    local spawnTilesNames = {
        "grass",
    }
   
    local randX, randY = math.random(from.x, to.x), math.random(from.y, to.y)
    local random = {x=randX, y=randY, z=7}
    local randomTile = Tile(random)
   
    local thing = randomTile:getThing()
        for _,v in ipairs(spawnTilesNames) do
            if (thing:getName() == v) and (randomTile:getThingCount() <= 1) then
                doCreateItem(itemId, itemCount, randomTile:getPosition())
            end
        end
    end

This just doesn't make sense.
I don't know exactly what you want to happen.

I can usually guess using context clues, but I honestly can't figure it out.

Please explain more clearly.

----------

as an aside ..

instead of this

for _,v in ipairs(spawnTilesNames) do
    if (thing:getName() == v) and (randomTile:getThingCount() <= 1) then
        doCreateItem(itemId, itemCount, randomTile:getPosition())
    end
end

I'd suggest doing it like this.

if table.contains(spawnTilesNames, thing:getName()) and randomTile:getThingCount() <= 1 then
    Game.createItem(itemId, itemCount, randomTile:getPosition())
end

I need before creating the item to check if that position is authorized and only then create the item, if it is not authorized to generate a new position. Sorry for bad english.

So the tile having the name of 'grass' authorizes the tile..
If the tile is not authorized, do you want it to keep re-attempting new positions until one is found? Maybe with a cut-off of X number of attempts?

Well, that's my best guess, so here you go. xD

if spawnItemOnArea(Position(240, 237, 7), Position(254, 247, 7), 2173, 1, 100) then
    print("Item successfully spawned on a random authorized tile, that did not have any other items on it.")
else
    print("No items were able to be spawned.")
end

function spawnItemOnArea(from, to, itemId, itemCount, maxAttempts)    
    local spawnTilesNames = {
        "grass",
    }
    
    for i = 1, maxAttempts do
        local randX, randY = math.random(from.x, to.x), math.random(from.y, to.y)
        local randomPosition = Position(randX, randY, 7)
        local randomTile = Tile(randomPosition)
        
        local groundTile = randomTile:getGround()
        if table.contains(spawnTilesNames, groundTile:getName()) and randomTile:getThingCount() <= 1 then
            Game.createItem(itemId, itemCount, randomPosition)
            return true
        end
    end
    
    return false
end
