I’ve been working on a player controller and I just can’t seem to get the basics of the controller right. All of the tutorials out there are messy with features that I neither need nor want. Can someone please provide me with code for a controller that I can copy/paste into visual studio that does only these basic things:
- Move character forwards, backwards, left and right.
- Moves character in direction based on camera orientation.
- Rotates character towards direction they are (or were) moving in.
To be clear, I won’t just copy your work. I just really need something basic to look at and figure out. I really want to learn but no matter how much I try I keep coming back to this same issue. I know this is probably something really easy to code but it would mean soooo much to me by giving me something clean and basic to learn and jump off from.
here is my code. Please read through my comments and if you don’t understand something, or it’s causing problems please speak up. I’m always happy to help

public float rotationDamping = 6;
//used to smooth the movement and get rid of laggy characteristics - greater values = less time
public float movementDamping = 2;
//how fast are you moving? - greater values = faster character
public float movementSpeed = 5;
// Start is called before the first frame update

//get a reference to the main camera

*create a script called “MyCharacterController”
*copy paste
*put script onto your character
*play and change to fit your needs
@JxWolfe Do you want to exchange discords or something? This means so much to me and I want to repay the favor somehow. If you’re ever interested in 3d modeling, animation, or digital art hit me up!
