necesito que, en android exclusivamente, el preview aparezca en un inicio al centro de la camara

Pensamiento

Adjusting preview on Android

The user wants the building preview (_toBuild) to start centered in the camera view on Android systems, instead of its initial position, likely under the finger. This change should happen when building mode starts. I think it involves setting initial coordinates in a platform-specific way (Android only). The current code only adjusts _toBuild when the user interacts with the touch screen, so I’ll need to find a way to position it centrally during initialization on Android. I'll check the mobile input handling logic to adjust this.

Modifying preview display on Android

To meet the user's request to center the building preview on Android startup, I’ll update the _PrepareBuilding method. I’ll adjust the position of _toBuild to the camera's center, snapped to the grid. This change will be wrapped in UNITY_ANDROID to apply exclusively to Android builds. I’ll also ensure _toBuild is active at the start and update its sorting order. The logic should be updated for Android only, and I need to account for edge cases like grid snapping.

Respuesta

Para que el preview aparezca, solo en Android, centrado en la cámara justo al entrar en modo construcción, basta con colocar el objeto _toBuild en el centro de la pantalla dentro de _PrepareBuilding().
Añade (o sustituye) el bloque marcado con // ★ NUEVO:

csharp
protected override void _PrepareBuilding()
{
    base._PrepareBuilding();
    _EnableGridVisual(true);
    scriptGlobalUI.CloseGlobalPanels();
    script0UI.MostrarIndicaciones();

#if UNITY_ANDROID          // ← solo en builds Android
    script0UI.BotonesConsOn();

    // ★ NUEVO – mostrar el preview en el centro de la cámara
    if (_toBuild != null && Camera.main != null)
    {
        // centro de la pantalla en píxeles
        Vector3 screenCenter = new Vector3(Screen.width * 0.5f,
                                           Screen.height * 0.5f,
                                           Mathf.Abs(Camera.main.transform.position.z)); // distancia z

        // pasar a coordenadas mundo
        Vector2 worldCenter = Camera.main.ScreenToWorldPoint(screenCenter);

        // ajustar a la rejilla (cartesiana o isométrica)
        Vector2 snapped = isIsometric
            ? _ClampToNearestIsometric(worldCenter, cellSize)
            : _ClampToNearest(worldCenter, cellSize);

        // activar y posicionar el preview
        _toBuild.SetActive(true);
        _toBuild.transform.position = new Vector3(snapped.x,
                                                  snapped.y,
                                                  _toBuild.transform.position.z);

        // corregir el orden de dibujado
        foreach (var sr in _toBuild.GetComponent<BuildingManager>().spriteRenderers)
            sr.sortingOrder = _CalculateSortingOrder(sr.transform.position) + 1000;
    }
#else                     // ← PC / iOS / editor
    IsPlacingBuilding = true;
#endif

    IsPlacingBuilding = true;
}

Qué hace el bloque nuevo

  1. Obtiene el centro de la pantalla (Screen.width/2, Screen.height/2).
  2. Lo convierte a mundo con Camera.main.ScreenToWorldPoint.
  3. Aplica snap a la celda usando el método apropiado (_ClampToNearest o _ClampToNearestIsometric).
  4. Activa el objeto _toBuild (por si estaba oculto) y lo coloca en esa posición.
  5. Actualiza el sortingOrder para que quede sobre el resto de sprites durante la previsualización.

Con esta pequeña adición, al pulsar ―por ejemplo― un botón de construir en Android, el edificio de prueba aparecerá inmediatamente centrado en la vista, y el usuario podrá empezar a arrastrarlo sin tener que “cazarlo” primero.
