How to programmatically add Tilemaps to a Grid
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am new to Unity3d and I'm trying to make my first 2d game.
In order to create Tilemaps in Unity, we usually right-click then choose 2D Object > Tilemap, which gives us a Grid + Tilemap, each child tilemap in that grid is considered a layer.
What I want is to be able to generate/add tilemaps with a script to an empty Grid (everytime empty the Grid then add layers).
I want to make a map system where the map is generated using binary files every time the player changes the map.
Is that possible?

Sure it's possible. You would use Tilemap.SetTile. Then it's just a matter of mapping your binary file, the tiles, and your grid spacing all together.

But I have an emptyGrid, I need to first add layers (Tilemap objects) to it. That's what I don't know how to do :/

I believe the tilemap layers are nothing more than a gameobject with a TileMap and TileMapRenderer components on it. You can instantiate this and make it a child of the Grid. And then you just need to run the SetTile method on the appropriate Gameobject/tilemap. Haven't tested this but fairly certain that's how it'd work.

And how would I instantiate a Gameobject, add TileMap/TileMapRenderer and make the Grid its parent please?

Thanks to @ryeMoss, I ended up doing the following:
private Tilemap CreateTilemap(string tilemapName)
{
var go = new GameObject(tilemapName);
var tm = go.AddComponent<Tilemap>();
var tr = go.AddComponent<TilemapRenderer>();
tm.tileAnchor = new Vector3(AnchorX, AnchorY, 0);
go.transform.SetParent(_mapGrid.transform);
tr.sortingLayerName = "Main";
return tm;
}
