Cube Not Visible.

[Yue]

I am creating a cube for my third person camera pivot. But the cube is not visible, although the camera is pivoting to its position.

 

Camera3rdPerson = {}

Camera3rdPerson.__index = Camera3rdPerson

 

function Camera3rdPerson:New(world)

    local this = setmetatable({}, Camera3rdPerson)

 

    Print("✅ [Camera3rdPerson] Sistema de cámara orbital inicializado.")

 

 -- 🌌 Crear cámara vinculada al mundo

    local camera = CreateCamera(world:GetWorld())

    camera:SetOrder(-1) -- Se renderiza primero

    camera:SetPosition(0,2,-2)

   

    local pivotCamera = CreateBox(world:GetWorld(), 0.2)

    pivotCamera:SetColor(1, 1, 0, 1) -- Amarillo brillante para debug

    pivotCamera:SetPosition(0, 2, 0,true) -- Altura media, ajustable luego

 

    camera:Point(pivotCamera)

 

 

The cube is there, the camera is looking at it. 

 

function this:Update()

        --Print("📡 [Camera] Update activo en Nivel01.")

 

        pivotCamera:Move(0,0.001,0)

    end

 

The cube is visible and starts to move upwards .

Temporary solution
 

    ---------------------------------------------------

    -- 🔁 Actualizar posición de la cámara cada frame

    ---------------------------------------------------

    function this:Update()

        --Print("📡 [Camera] Update activo en Nivel01.")

       

        if self._forceCheck then

            local _ = pivotCamera:GetHidden()

            self._forceCheck = false

        end

 

      

    end

In your code above pivotCamera is being declared as a local variable. The real mystery is how the program is not crashing in the Update method, since there is no global pivotCamera value declared? I need to see your whole code file to tell what is going on.

Ok i sent the file by inbox

[Josh]

I don't see any error in your code. I will need to full project in order to investigate this.

Closing due to lack of information.

At the moment, until now I see it. Wait, I'll send you the project inbox.

[Yue]

Ok, I already sent the project. Sorry, I had not noticed this entry.

This is what I see when I run the project:

You code is using 0 for the size of the box, which will make it not visible.

local pivotPlayer = CreateBox(world, 0)

When I changed the size to 0.2, I see this:

How do I make the bug occur?

[Yue]

Here video.

In your video you are declaring the box variable as a local variable. Therefore, it will go out of scope and be deleted on the next garbage collection cleanup.

When I declared it as a global variable it works as expected.

Thanks You.
