basic movement c# code example

Example 1: movement script c#

using UnityEngine;
using System.Collections;

// This script moves the character controller forward
// and sideways based on the arrow keys.
// It also jumps when pressing space.
// Make sure to attach a character controller to the same game object.
// It is recommended that you make only one call to Move or SimpleMove per frame.

public class ExampleClass : MonoBehaviour
{
    CharacterController characterController;

    public float speed = 6.0f;
    public float jumpSpeed = 8.0f;
    public float gravity = 20.0f;

    private Vector3 moveDirection = Vector3.zero;

    void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    void Update()
    {
        if (characterController.isGrounded)
        {
            // We are grounded, so recalculate
            // move direction directly from axes

            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0.0f, Input.GetAxis("Vertical"));
            moveDirection *= speed;

            if (Input.GetButton("Jump"))
            {
                moveDirection.y = jumpSpeed;
            }
        }

        // Apply gravity. Gravity is multiplied by deltaTime twice (once here, and once below
        // when the moveDirection is multiplied by deltaTime). This is because gravity should be applied
        // as an acceleration (ms^-2)
        moveDirection.y -= gravity * Time.deltaTime;

        // Move the controller
        characterController.Move(moveDirection * Time.deltaTime);
    }
}

Example 2: C# movement

Rigidbody2D body;

float horizontal;
float vertical;
float moveLimiter = 0.7f;

public float runSpeed = 20.0f;

void Start ()
{
   body = GetComponent<Rigidbody2D>();
}

void Update()
{
   // Gives a value between -1 and 1
   horizontal = Input.GetAxisRaw("Horizontal"); // -1 is left
   vertical = Input.GetAxisRaw("Vertical"); // -1 is down
}

void FixedUpdate()
{
   if (horizontal != 0 && vertical != 0) // Check for diagonal movement
   {
      // limit movement speed diagonally, so you move at 70% speed
      horizontal *= moveLimiter;
      vertical *= moveLimiter;
   } 

   body.velocity = new Vector2(horizontal * runSpeed, vertical * runSpeed);
}
