This is a script you can add to a Unity Camera to give it basic controls mimicking the functions of the scene view:
using UnityEngine;
using System.Collections;
public class CameraBehavior : MonoBehaviour
{
public float Normal_Speed = 25.0f; //Normal movement speed
public float Shift_Speed = 54.0f; //multiplies movement speed by how long shift is held down.
public float Speed_Cap = 54.0f; //Max cap for speed when shift is held down
public float Camera_Sensitivity = 0.6f; //How sensitive it with mouse
private Vector3 Mouse_Location = new Vector3(255, 255, 255); //Mouse location on screen during play (Set to near the middle of the screen)
private float Total_Speed = 1.0f; //Total speed variable for shift
void Update()
{
//Camera angles based on mouse position
Mouse_Location = Input.mousePosition - Mouse_Location;
Mouse_Location = new Vector3(-Mouse_Location.y * Camera_Sensitivity, Mouse_Location.x * Camera_Sensitivity, 0);
Mouse_Location = new Vector3(transform.eulerAngles.x + Mouse_Location.x, transform.eulerAngles.y + Mouse_Location.y, 0);
transform.eulerAngles = Mouse_Location;
Mouse_Location = Input.mousePosition;
//Keyboard controls
Vector3 Cam = GetBaseInput();
if (Input.GetKey(KeyCode.LeftShift))
{
Total_Speed += Time.deltaTime;
Cam = Cam * Total_Speed * Shift_Speed;
Cam.x = Mathf.Clamp(Cam.x, -Speed_Cap, Speed_Cap);
Cam.y = Mathf.Clamp(Cam.y, -Speed_Cap, Speed_Cap);
Cam.z = Mathf.Clamp(Cam.z, -Speed_Cap, Speed_Cap);
}
else
{
Total_Speed = Mathf.Clamp(Total_Speed * 0.5f, 1f, 1000f);
Cam = Cam * Normal_Speed;
}
Cam = Cam * Time.deltaTime;
Vector3 newPosition = transform.position;
if (Input.GetKey(KeyCode.Space))
{
//If the player wants to move on X and Z axis only by pressing space (good for re-adjusting angle shots)
transform.Translate(Cam);
newPosition.x = transform.position.x;
newPosition.z = transform.position.z;
transform.position = newPosition;
}
else
{
transform.Translate(Cam);
}
}
private Vector3 GetBaseInput()
{
Vector3 Camera_Velocity = new Vector3();
float HorizontalInput = Input.GetAxis("Horizontal"); // Input for horizontal movement
float VerticalInput = Input.GetAxis("Vertical"); // Input for Vertical movement
// Horizontal movement
Camera_Velocity += new Vector3(HorizontalInput, 0, 0);
// Forward and backward movement
Camera_Velocity += new Vector3(0, 0, VerticalInput);
// Downwards movement (Y-axis) when Q is pressed
if (Input.GetKey(KeyCode.Q))
{
Camera_Velocity -= new Vector3(0, 1, 0);
}
// Upwards movement (Y-axis) when E is pressed
if (Input.GetKey(KeyCode.E))
{
Camera_Velocity += new Vector3(0, 1, 0);
}
return Camera_Velocity;
}
}
