Not getting right value; ScreenPointToRay
I am creating an RTS Move system, where selected units will move to mouse click location. I have created a ray from my mouse click and I'm getting an incorrect value for RaycastHit. Please look over my code and tell me if I'm doing it wrong.
using UnityEngine;
using System.Collections;
public class UserInput : MonoBehaviour {
Vector2 beginMousePos;
Vector2 currMousePos;
bool mouseIsSet = false;
RaycastHit hit;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.GetMouseButtonDown (0) & !mouseIsSet)
{
mouseIsSet = true;
beginMousePos = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
}
else if(Input.GetMouseButtonUp (0) & mouseIsSet)
{
mouseIsSet = false;
currMousePos = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
UnitManager.FindSelectedUnits(beginMousePos, currMousePos);
}
if(Input.GetMouseButtonDown (1))
{
Debug.Log ("(" + currMousePos.x + "'" + currMousePos.y + ") ("
+ beginMousePos.x + "'" + beginMousePos.y + ")");
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast (ray, out hit))
{
UnitManager.MoveSelectedUnits (hit.transform.position);
}
}
}
}
What are you trying to hit with the ray? If it's the ground, does the ground have a collider on it? Are there any colliders between your camera and the ground? Try printing out hit.collider.name or hit.collider.tag (and check that hit.collider.tag is a tag that you are interested in hitting).
I figured it out a $$anonymous$$ute ago... Yep the ground and then I wanted the location of the hit, but ins$$anonymous$$d I was getting the location of my plane, when I realized this, it was a no brainer that hit.tranform.position was not what I wanted, after checking reference I fount hit.point was the accurate vector3 to obtain from my raycasthit... Thanks for you help though, I really appreciate it.
