团结 - 在陆地上生成敌人

Question

I am new at Unity and I am stuck on one thing. I would like to ensure that the enemies spawn on the grass and not in the water and not on the colliders. I created the map using the Tiled program. Is there an effective solution? Thank you.

If you are writing a strategy type game, you will need to store data about the map tiles in a 2D array like Map[x,y] so you can calculate things like movement, combat, resource gathering,victory points.

I have a TileType structure containing info on each tile based on your game rule requirements eg:

    struct TileType
{
    public int TerrainType;     // Terain type 1= grass 2= water 3 = city etc
    public int rot;             // Rotation of sprite to create variation (1-4,1=90 deg,2=180 deg etc
    public string Name;         // Description of tile type eg "Sports Store"
    public string SpriteName;   // string of sprite to use to display tile
    public bool SeeThrough;     // True if Tile allows LOS through it
}

I would set up the map as a 2D array of these tileType as follows:

private TileType[,] Map = new TileType[MapMaxX, MapMaxY];

You can then allow your game logic (ie where to spawn units) to check the proposed tile is legal as follows

if ((Map[x, y].TerrainType=1))  // Grass tile
      { return true; }
    else
    {
        return false;     // Non grass tile
    }
