Using CharacterController

1. Setup: Attach a CharacterController component to your player GameObject. This component allows for easy movement and collision detection without using physics forces.
2. Basic Movement Script: Here’s a simple script to get you started with player movement using the CharacterController:

using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
private CharacterController controller;
public float speed = 5.0f;
public float jumpHeight = 1.5f;
private Vector3 playerVelocity;
private bool groundedPlayer;
void Start()
{
controller = gameObject.AddComponent<CharacterController>();
}
void Update()
{
groundedPlayer = controller.isGrounded;
if (groundedPlayer && playerVelocity.y < 0)
{
playerVelocity.y = 0f;
}
float moveX = Input.GetAxis("Horizontal");
float moveZ = Input.GetAxis("Vertical");
Vector3 move = new Vector3(moveX, 0, moveZ);
controller.Move(move * speed * Time.deltaTime);
if (Input.GetButtonDown("Jump") && groundedPlayer)
{
playerVelocity.y += Mathf.Sqrt(jumpHeight * -2f * Physics.gravity.y);
}
playerVelocity.y += Physics.gravity.y * Time.deltaTime;
controller.Move(playerVelocity * Time.deltaTime);
}
}

Using Rigidbody

1. Setup: Attach a Rigidbody component to your player GameObject. This allows for physics-based movement.
2. Basic Movement Script: Here’s a simple script for player movement using Rigidbody:

using UnityEngine;
public class PlayerMovementRigidbody : MonoBehaviour
{
private Rigidbody rb;
public float moveSpeed = 5f;
void Start()
{
rb = GetComponent<Rigidbody>();
}
void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical) * moveSpeed;
rb.MovePosition(transform.position + movement * Time.fixedDeltaTime);
}
}
