Spawn referencable objects with RayCast

Hello,
i’m new to Unity and the whole scripting-thingy and am currently working on a RTS-Game with the Fury Framework.

I’m looking for a way, to spawn referencable objects with a click on a built terrain.

What i currently use:

public GameObject BuildingType;

[...]

PlaceBuilding(Input.mousePosition);

[...]

public void PlaceBuilding(Vector2 mousePosition)
{
     RaycastHit hit = RayFromCamera(mousePosition, 1000.0f);
     GameObject.Instantiate(BuildingType, hit.point, Quaternion.identity);
}

public RaycastHit RayFromCamera(Vector3 mousePosition, float rayLength)
{
     RaycastHit hit;
     Ray ray = Camera.main.ScreenPointToRay(mousePosition);
     Physics.Raycast(ray, out hit, rayLength);
     return hit;
}

I experience two problems with this:

  1. The building spawns, but always spawns right in the middle of the screen/camera instead of where the mouse is. (I’m using custom-textured mouse-cursors)
  2. How can i add specific scripts to these newly spawned objects (i can only modify them when the game is running) and use them as individual objects?

Thanks in advance!

To raycast at mouse position, you ray should be like this:

ray = Camera.main.ScreenPointToRay(Input.mousePosition);

For adding scripts to the objects: GameObject.AddComponent.
