(Solved) Third Person Camera, again....

I want to make my own TPS style, I want to mimic gta san andreas which is smooth and never lags behind whatever how fast targeted move.

I am not using Parent-child method because it makes me confused if I want to change target camera, everything input function I did it by script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class InputHandler : MonoBehaviour
6. {
7.     public Camera camera;
8.     public Animator mecAnim;
9.    
10.     void Awake()
11.     {
12.         if (camera == null)
13.             camera = Camera.current;
14.         if (mecAnim == null)
15.             mecAnim = GameObject.FindObjectOfType<Animator>();
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.         controlCharacterByRootMotion(mecAnim);
22.         FollowCameraToObject(camera.transform, mecAnim.transform);
23.     }
24.  
25.     public Vector3 offset = new Vector3(0, 1.25f, -3f);
26.     Vector3 followPos;
27.  
28.     void FollowCameraToObject(Transform cameraTrans, Transform targetTrans)
29.     {
30.         targetTrans.Rotate(new Vector3 (Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")));
31.  
32.         followPos = (targetTrans.forward * offset.z)
33.             + (targetTrans.right * offset.x)
34.             + (targetTrans.up * offset.y)
35.             + targetTrans.position;
36.  
37.         cameraTrans.position = followPos;
38.         cameraTrans.LookAt(targetTrans.position + new Vector3 (offset.x, offset.y, targetTrans.forward.z));
39.     }
40.  
41.     void controlCharacterByRootMotion(Animator animator)
42.     {
43.         animator.SetFloat("Straight", Input.GetAxis("Vertical"));
44.         animator.SetFloat("Strafe", Input.GetAxis("Horizontal"));
45.     }
46. }
47.  

as you can see that I rotate targetTrans, but actually I don't want to do that. I just want to do orbit movement for camera. What should I do? sorry my code is complicated. Please use short and simple sentence so I can understand clearly.

 

Wow this forum so helpful! once again, I've figured out myself even no one replies!

Code (CSharp):

1. void FollowCameraToObject(Transform cameraTrans, Transform targetTrans)
2.     {
3.         yaw += Input.GetAxis("Mouse X") * 10;
4.         pitch -= Input.GetAxis("Mouse Y") * 10;
5.         pitch = Mathf.Clamp(pitch, minPitch, maxPitch);
6.         Vector3 targetRotation = new Vector3(pitch, yaw);
7.         cameraTrans.eulerAngles = targetRotation;
8.         followPos = targetTrans.position + new Vector3(0, 1.75f,0);
9.         cameraTrans.position = followPos + cameraTrans.TransformDirection(offset);
10.     }

 

Hey RxGian, your script helped me with the approach. Thank you for sharing, I am also adding a minYaw and maxYaw to stop the complete 360 rotation and make it more like the camera in GTA games. Thanks again!
