How can i get in real time the speed movement of each camera ?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class UserInformation : MonoBehaviour
{
public Text cameraText;
public Text cameraSpeed;
public Text cameraOriginalPosition;
public Transform target;
public SwitchCameras switchcameras;
private Vector3[] prevCamerasPosition;
private Camera[] Cameras;
private int cameraIndex = 0;
// Use this for initialization
void Start()
{
Cameras = switchcameras.cameras;
if (Cameras.Length > 0)
{
prevCamerasPosition = new Vector3[Cameras.Length];
for (int i = 0; i < Cameras.Length; i++)
{
prevCamerasPosition[i] = Cameras[i].transform.position;
}
}
}
// Update is called once per frame
void Update()
{
if (cameraIndex == Cameras.Length)
cameraIndex = 0;
if (Cameras[cameraIndex].enabled == true)
{
cameraText.text = Cameras[cameraIndex].name;
//cameraSpeed.text =
cameraOriginalPosition.text = prevCamerasPosition[cameraIndex].ToString();
}
else
{
cameraIndex++;
}
}
}
I can get the name and original start position but now i need to get the speed in real time and assign it to: cameraSpeed.text = I want to calculate and display the real time of each camera movement speed.
Another sub question: Do i need to change the Update to FixedUpdate or LateUpdate ?

Hey mate, you need to store the position of the camera in the last update and then check the difference in position this update.
Vector3 lastPosition
void Update()
{
float camSpeed = (transform.position - lastPosition).magnitude / Iime.deltaTime;
cameraSpeed.text = camSpeed.ToString();
lastPosition = transform.position;
}
In the future check around lots of people have asked similar questions here.
