Raycasts and Tags

Unity Engine

Here’s a small snippet of my code that I’m having troubles with. I’m trying to allow the user to move objects around a scene by “grabbing” them with their finger and physically moving them. However, I only want this to happen when they grab an object with a tag of “moveable”. Otherwise, I’d like this gesture to move the camera. Here’s my code:

private var currTarget: Transform;
private var dragging: boolean;
private var clickOffset: Vector3;
var cam: Transform;


function Update () {
	var objPlane: Plane;
	var hitDist: float;
	var hit: RaycastHit;


	if (Input.GetMouseButton(0)) {
		ray = Camera.main.ScreenPointToRay(Input.mousePosition);

		if (dragging) {	
			objPlane = new Plane(Camera.main.transform.forward, currTarget.position);
			objPlane.Raycast(ray, hitDist);
			if (hit.tag == "Wall"){
				currTarget.position = ray.GetPoint(hitDist) + clickOffset;
			}
			else{
				cam.position = ray.GetPoint(hitDist) + clickOffset;
			}
		} else if (Physics.Raycast(ray, hit)  Input.GetMouseButtonDown(0)) {
			dragging = true;
			currTarget = hit.transform;
			
			objPlane = new Plane(Camera.main.transform.forward, currTarget.position);
			objPlane.Raycast(ray, hitDist);
			clickOffset = currTarget.position - ray.GetPoint(hitDist);
		}
	} else {
		dragging = false;
	}
}

The problem I’m having is that Unity is telling me:

Can anyone help me? Thank you in advance.

You need to access the transform stored in raycast hit and alike. Please check the Script Reference of the RaycastHit class to see what type of objects it transports

so hit.transform.tag ?

This does not work. What am I doing wrong?

hit.collider.tag
