basic movement system unity code example
Example 1: how to add movement in unity
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
private string moveInputAxis = "Vertical";
public float moveSpeed = 0.1f;
public Rigidbody rb;
public bool cubeIsOnTheGround = true;
void Start()
{
rb = GetComponent<Rigidbody>();
}
void Update()
{
float moveAxis = Input.GetAxis(moveInputAxis);
ApplyInput(moveAxis);
if(Input.GetButtonDown("Jump") && cubeIsOnTheGround == true)
{
rb.AddForce(new Vector3(0, 7, 0), ForceMode.Impulse);
cubeIsOnTheGround = false;
}
private void ApplyInput(float moveInput)
{
Move(moveInput);
}
private void Move(float input)
{
transform.Translate(Vector3.forward * input * moveSpeed);
}
private void OnCollisionEnter(Collision collision) {
if(collision.gameObject.tag == "Ground") {
cubeIsOnTheGround = true;
}
}
}
Example 2: 3d movement unity
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ThirdPersonMovement : MonoBehaviour
{
public CharacterController controller;
public Transform cam;
public float speed = 6f;
public float turnSmoothTime = 0.1f;
float turnSmoothVelocity;
void Update()
{
float horizontal = Input.GetAxisRaw("Horizontal");
float vertical = Input.GetAxisRaw("Vertical");
Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
if (direction.magnitude >= 0.1f)
{
float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
transform.rotation = Quaternion.Euler(0f, angle, 0f);
Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
controller.Move(moveDir.normalized * speed * Time.deltaTime);
}
}
}
Example 3: 3d movement unity
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playerMovement : MonoBehaviour {
public float speed = 25.0F;
public float jumpSpeed = 8.0F;
public float gravity = 20.0F;
private Vector3 moveDirection = Vector3.zero;
private float turner;
private float looker;
public float sensitivity = 5;
void Start () {
}
void Update () {
CharacterController controller = GetComponent<CharacterController>();
if (controller.isGrounded) {
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton("Jump")moveDirection.y = jumpSpeed; } turner = Input.GetAxis ("Mouse X")* sensitivity; looker = -Input.GetAxis ("Mouse Y")* sensitivity; if(turner != 0){
