Getting Object Position?(Confused and Might need assistance)

[halfrose]

Ok so I Took notice of 'get random position':

local function getrandomposition(caster)
 local ground = TheWorld
 local centers = {}
   for i, node in ipairs(ground.topology.nodes) do
        if ground.Map:IsPassableAtPoint(node.x, 0, node.y) then
            table.insert(centers, {x = node.x, z = node.y})
        end
    end 
    if #centers > 0 then
        local pos = centers[math.random(#centers)]
        return pos.x, 0, pos.z
    else
        return caster:GetPosition()
    end
end

However I'm trying to get the position of an object stead so I can make that once an object is used, it spawns it at the location of the object. I have no idea how to do that, attempts on it resulted in the object not spawning or crashing.

Is there any way to replace the 'math.random' ? if not is there anyway to get the position of an object through x,y,z ?

Let 'A' be the already placed entity, and 'B' be the one you want to place.

local x,y,z = A.Transform:GetWorldPosition()
A:Remove()
local B = SpawnPrefab("bob")
B.Transform:SetPosition(x,y,z)

Or are you trying to find all entities at a position?

local ents = TheSim:FindEntities(x, y, z)
for _,ent in ipairs(ents)
do
    if ent.prefab == "bob_spawner"
    then
        local x,y,z = ent.Transform:GetWorldPosition()
        ent:Remove()
        local B = SpawnPrefab("bob")
        B.Transform:SetPosition(x, y, z)
    end
end

 

Or are you trying to hook into an already made function from the core game files?  If so, then post file names/line numbers/etc with what you're trying to hook.

Sorry for taking so long to reply, lots of stuff mid week. I'll give a shot on what you provided here.

To iterate better, looking at how I worded myself. What I'm basically trying to do is a gun that shoots portals. Basically when it shoots a portal open, it should automatically spawn an exit portal at the position of another object that remains in one place.
