Unity Script to give camera WASD + mouse control

Writen by Windexglow 11-13-10. Use it, edit it, steal it I don't care.
Converted to C# 27-02-13 - no credit wanted.
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*/

Is there anyway I can get the player to move the way the camera is facing? I am making a first person game.

@JDRBL007 You should be able to attach this script and camera to your player. Then when the script updates the transform, that will adjust the player

Thank's for sharing. Saved me a lot of work.
I made a modification that makes it posible to deactivate the flycamera by hitting esc, and activate it again by hitting F1. I think it's usefull if you want's to modify something in the scene while keeping the cameraposition fixed.

I'm sure there's a better way to implement this but it works.

void Update()
{
if (Input.GetKey(KeyCode.Escape))
{
activeFlyCamera = false;
savedCameraPosition = Camera.main.transform.eulerAngles;
savedCameraRotation = Camera.main.transform.rotation;
}

    if (Input.GetKey(KeyCode.F1))
    {
        activeFlyCamera = true;
        Camera.main.transform.eulerAngles = savedCameraPosition;
        Camera.main.transform.rotation = savedCameraRotation;
    }
        

    if (activeFlyCamera)
    {

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.

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.
