TileBase | Range based Single File MBTiles like Store | Runtime Evironment library

I am trying to make a building game, where you can build anywhere that there is no builds and touching the ground. Here is my code

so, I'm making a terraria-like game in unity 2019 on windws 10 using c# which has procedurally generated tilemaps and i have this script attached to a grid:

I'm attempting to implement the A* pathfinding algorithm for a 2d hexagonal tilemap. I've got the following HexCell class that acts as a data container and adjacency finder using a hex index integer:

I have made a basic scripted tile, it have set prefab as game object. Problem is, that gameobject is offset when door is placed. I would like to have gameobject on same location as tile.

IMAGE: My problem

DoorTile.cs

So the way I did it was an O(n) solution:

I have a scenario where I will need to know certain information about all of the tiles in a tilemap. From the research I've done and questions that others have had, this may not be the easiest thing to do.

I am faced with 3 possible options, as far as I can tell:

1. Don't use Unity's Tilemap, and build the tiles out by hand instead via a list of GameObjects and sprites. Then attach any sort of model I may need with custom values as a script to said GO. This will make it very simple to add logic to each tile. The downsides will be that it'll be a lot more annoying to build out maps.

2. Use Unity's Tilemap, but keep track of each special node tile in code manually. Needless to say, this isn't a very attractive workflow, since any time the map changes, the change would have a need to reflect in the code map/list/array

3. Override Unity's Tiles (just like the 2d extras pack) and creates a rule tile for every special tile. When reading in the tiles, and compiling a dictionary, check the type of tile and assign any special properties based on the type of tile you're currently looking at. The rule tiles can either be visual tiles or painted on a tilemap underneath the visual tilemap used only for storing information of the map above it.

4. (3.1) Do the same as above, but instead of using special rule tiles, separate any special tiles onto their own special Tilemaps. Then read through each tilemap and compile a dictionary that keeps track of any special tiles and their special properties.

Currently I am using the following:

I have been trying to get the tiles of a Tilemap and I could get them with this code that I found in another question:

I have the following class definitions:

I am making a topdown tilebased 2D game. In this game, I want to make 1 of the walls into a mirror, like you can see on this video. Now, I know the game in the trailer is made in RPG Maker, but I want to make my game in Unity 3D.

I have tried to set a camera right next to the mirror, add a RenderTexture on the camera and set that texture on the Sprite, but of course it is not possible to convert a RenderTexture to a Sprite, so this did not end up working.

So my question is, is it possible to create a mirror like in the trailer?
