How to make an object rotate to raycast hit from mouse? Unity 3D
Sooooo. I was able to make my object move towards my raycast hit position from the mouse. But im having trouble making it rotate. It does rotate with a script i assembled together but, it does not rotate towards the raycast position. Im making a non-rts movement. So when i click it will move for a bit. But if i hold it will keep moving towards the direction of the raycast hit position. So its not rts or nav mesh movement.
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.AI;
public class PlayerMovement : MonoBehaviour {
public float speed = 10f;
private Vector3 targetPos;
private Vector3 startPos;
private Vector3 mousePos;
public void Start()
{
startPos = transform.position;
}
public void Update()
{
if (Input.GetMouseButton(0))
{
mousePos = Input.mousePosition;
Ray mouseCast = Camera.main.ScreenPointToRay(mousePos);
Plane groundPlane = new Plane(Vector3.up, Vector3.zero);
RaycastHit hit;
float rayLength;
if (Physics.Raycast(mouseCast, out hit, 100))
{
Debug.DrawLine(mousePos, targetPos, Color.blue);
targetPos = new Vector3(hit.point.x, 2f, hit.point.z);
}
if (groundPlane.Raycast(mouseCast, out rayLength))
{
Vector3 pointToLook = mouseCast.GetPoint(rayLength);
transform.LookAt(new Vector3(pointToLook.z, transform.position.y, pointToLook.z));
}
transform.position = Vector3.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
}
}
}
This code here is the movement plus the non-working rotation stuff in there. ANd its not working it will rotate but not in the right direction. Me is New.
I updated some code, but what I have works fine with my little test. Moves towards and looks at where I am click/click-holding. I also added a little movement margin, so the character wouldn't move/look twitch with little mouse movement. The main fix though... was just look at your targetPos.
public void Update()
{
if (Input.GetMouseButton(0))
{
mousePos = Input.mousePosition;
Ray mouseCast = Camera.main.ScreenPointToRay(mousePos);
Plane groundPlane = new Plane(Vector3.up, Vector3.zero);
RaycastHit hit;
float rayLength;
if (Physics.Raycast(mouseCast, out hit, 100))
{
Debug.DrawLine(mousePos, targetPos, Color.blue);
targetPos = new Vector3(hit.point.x, 0f, hit.point.z);
// We need some distance margin with our movement
// or else the character could twitch back and forth with slight movement
if (Vector3.Distance(targetPos, transform.position) >= 0.5f)
{
transform.LookAt(targetPos);
transform.position = Vector3.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
}
}
}
}
