Я следую учебному пособию по игре Unity 2D. Игрок и враг наследуют от базового класса, известного как MovingObject. Все в игре работает отлично, за исключением того, что игрок и враг не могут двигаться. Вот сценарии. Движение происходит в виде сетки в виде сетки.
Это оригинальная серия уроков. Попробуйте просмотреть движущийся объект, игрока и учебники противника. https://www.youtube.com/playlist?list=PLX2vGYjWbI0SKsNH5Rkpxvxr1dPE0Lw8F
Базовый класс MovingObject:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public abstract class MovingObject : MonoBehaviour {
public float moveTime = 0.1f;
public LayerMask blockinglayer;
private BoxCollider2D boxCollider;
private Rigidbody2D rb2D;
private float inverseMoveTime;
// Use this for initialization
protected virtual void Start () {
boxCollider = GetComponent<BoxCollider2D>();
rb2D = GetComponent<Rigidbody2D>();
inverseMoveTime = 1f / moveTime;
}
protected bool Move(int xDir, int yDir, out RaycastHit2D hit)
{
Vector2 start = transform.position;
Vector2 end = start + new Vector2(xDir, yDir);
boxCollider.enabled = false;
hit = Physics2D.Linecast(start, end, blockinglayer);
boxCollider.enabled = true;
if (hit.transform == null)
{
StartCoroutine(SmoothMovement(end));
return true;
}
return false;
}
protected IEnumerator SmoothMovement(Vector3 end)
{
float sqrRemainingDistance = (transform.position - end).sqrMagnitude;
while (sqrRemainingDistance > float.Epsilon)
{
Vector3 newPosition = Vector3.MoveTowards(rb2D.position, end, inverseMoveTime * Time.deltaTime);
rb2D.MovePosition(newPosition);
sqrRemainingDistance = (transform.position - end).sqrMagnitude;
yield return null;
}
}
protected virtual void AttemptMove<T>(int xDir, int yDir)
where T : Component
{
RaycastHit2D hit;
bool canMove= Move(xDir, yDir, out hit);
if (hit.transform == null)
{
return;
}
T hitComponent = hit.transform.GetComponent<T>();
if(!canMove && hitComponent != null)
{
OnCantMove(hitComponent);
}
}
protected abstract void OnCantMove<T>(T component)
where T : Component;
// Update is called once per frame
}
Сценарий игрока:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class Player : MovingObject {
public int wallDamage = 1;
public int pointsPerFood = 10;
public int pointsPerSoda = 20;
public float restartLevelDelay = 1f;
private Animator animator;
private int food;
// Use this for initialization
protected override void Start () {
animator = GetComponent<Animator>();
food = GameManager.instance.playerFoodPoints;
base.Start();
}
private void OnDisable()
{
GameManager.instance.playerFoodPoints = food;
}
// Update is called once per frame
void Update () {
if (GameManager.instance.playersTurn)
{
return;
}
int horizontal = 0;
int vertical = 0;
horizontal = (int)Input.GetAxisRaw("Horizontal");
vertical = (int)Input.GetAxisRaw("Vertical");
if (horizontal != 0)
{
vertical = 0;
}
if(horizontal!=0 || vertical != 0)
{
AttemptMove<Wall>(horizontal, vertical);
}
}
protected override void OnCantMove<T>(T component)
{
Wall hitwall = component as Wall;
hitwall.damageWall(wallDamage);
animator.SetTrigger("playerChop");
}
protected override void AttemptMove<T>(int xDir, int yDir)
{
food--;
base.AttemptMove<T>(xDir, yDir);
RaycastHit2D hit;
CheckIfGameOver();
GameManager.instance.playersTurn = false;
}
public void LoseFood(int loss)
{
animator.SetTrigger("playerHit");
food -= loss;
CheckIfGameOver();
}
private void OnTriggerEnter2D(Collider2D other)
{
if (other.tag == "Exit")
{
Invoke("Restart", restartLevelDelay);
enabled = false;
}
else if (other.tag == "Food")
{
food += pointsPerFood;
other.gameObject.SetActive(false);
}
else if (other.tag == "Soda")
{
food += pointsPerSoda;
other.gameObject.SetActive(false);
}
}
private void Restart()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}
private void CheckIfGameOver()
{
if (food <= 0)
{
GameManager.instance.GameOver();
}
}
}
Сценарий врага:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enemy : MovingObject {
public int playerDamage;
private Animator animator;
private Transform target;
private bool skipmove;
// Use this for initialization
protected override void Start () {
GameManager.instance.AddEnemyToList(this);
animator = GetComponent<Animator>();
target = GameObject.FindGameObjectWithTag("Player").transform;
base.Start();
}
protected override void AttemptMove<T>(int xDir, int yDir)
{
if (skipmove)
{
skipmove = false;
return;
}
base.AttemptMove<T>(xDir, yDir);
}
public void MoveEnemy()
{
int xDir = 0;
int yDir = 0;
if (Mathf.Abs(target.position.x - transform.position.x) < float.Epsilon)
{
yDir = target.position.y > transform.position.y ? 1 : -1;
}
else
{
xDir = target.position.x > transform.position.x ? 1 : -1;
AttemptMove<Player>(xDir,yDir);
}
}
protected override void OnCantMove<T>(T component)
{
Player hitplayer = component as Player;
animator.SetTrigger("enemyAttack");
hitplayer.LoseFood(playerDamage);
}
}
Я не уверен, есть ли у игрока или противника проблема с базовым сценарием. Может ли кто-нибудь помочь.
