Unity Script to give camera WASD + mouse control

    Simple flycam I made, since I couldn't find any others made public.  
    Made simple to use (drag and drop, done) for regular keyboard layout  
    wasd : basic movement
    shift : Makes camera accelerate
    space : Moves camera on X and Z axis only.  So camera doesn't gain any height*/
     
     
    float mainSpeed = 100.0f; //regular speed
    float shiftAdd = 250.0f; //multiplied by how long shift is held.  Basically running
    float maxShift = 1000.0f; //Maximum speed when holdin gshift
    float camSens = 0.25f; //How sensitive it with mouse

        transform.eulerAngles = lastMouse;
        lastMouse =  Input.mousePosition;
        //Mouse  camera angle done.  
       
        //Keyboard commands
        float f = 0.0f;
        Vector3 p = GetBaseInput();
        if (p.sqrMagnitude > 0){ // only move while a direction key is pressed

        Vector3 p_Velocity = new Vector3();

            p_Velocity += new Vector3(0, 0 , 1);
        }
        if (Input.GetKey (KeyCode.S)){

        }
        if (Input.GetKey (KeyCode.A)){
            p_Velocity += new Vector3(-1, 0, 0);
        }
        if (Input.GetKey (KeyCode.D)){
            p_Velocity += new Vector3(1, 0, 0);
        }
        return p_Velocity;
    }
}

Is there a way to make this script work with Rigid body? Or is there any other way to make the object collide with the camera and not just let it fly through?

Just needed a quick script for testing in play mode so I didn't have to rely on fixed camera positions and this works great for that. Thank you very much.

You're welcome! That's exactly why it's here :)

It's really close to what I was looking for. With some adjustments, it does what I need it for. Very neat!

i dont know if i am the only one but it simply doesnt work. i cheked unity official tutorials and copied the code they wrote, but didnt work. please someone help me. PS: using 2020.2.6f1

Did you name the file FlyCamera.cs?
You need to replace FlyCamera if you use another name.
