以下是用Unity3D引擎开发3D贪吃蛇游戏的示例代码:
```csharp
using System.Collections.Generic;
using UnityEngine;
public class SnakeController : MonoBehaviour
{
public GameObject snakeHeadPrefab;
public GameObject snakeBodyPrefab;
public float moveSpeed = 0.1f;
public float rotationSpeed = 5f;
public int initialBodySegments = 3;
private List<Transform> bodySegments = new List<Transform>();
private Vector3 moveDirection = Vector3.right;
private bool canRotate = true;
private bool isDead = false;
void Start()
{
SpawnSnake();
}
void Update()
{
if (!isDead)
{
MoveSnake();
CheckInput();
}
}
void SpawnSnake()
{
GameObject snakeHead = Instantiate(snakeHeadPrefab);
bodySegments.Add(snakeHead.transform);
for (int i = 0; i < initialBodySegments; i++)
{
AddBodySegment();
}
}
void AddBodySegment()
{
GameObject snakeBody = Instantiate(snakeBodyPrefab);
bodySegments.Add(snakeBody.transform);
}
void MoveSnake()
{
for (int i = bodySegments.Count - 1; i > 0; i--)
{
bodySegments[i].position = bodySegments[i - 1].position;
}
bodySegments[0].position += moveDirection * moveSpeed;
}
void CheckInput()
{
if (canRotate)
{
if (Input.GetKeyDown(KeyCode.RightArrow))
{
moveDirection = Quaternion.Euler(0f, 90f, 0f) * moveDirection;
canRotate = false;
RotateSnake();
}
else if (Input.GetKeyDown(KeyCode.LeftArrow))
{
moveDirection = Quaternion.Euler(0f, -90f, 0f) * moveDirection;
canRotate = false;
RotateSnake();
}
}
}
void RotateSnake()
{
for (int i = 0; i < bodySegments.Count - 1; i++)
{
Vector3 targetDirection = bodySegments[i + 1].position - bodySegments[i].position;
Quaternion targetRotation = Quaternion.LookRotation(targetDirection, Vector3.up);
bodySegments[i].rotation = Quaternion.Slerp(bodySegments[i].rotation, targetRotation, rotationSpeed * Time.deltaTime);
}
}
void OnTriggerEnter(Collider other)
{
if (other.CompareTag("Food"))
{
Destroy(other.gameObject);
AddBodySegment();
}
else if (other.CompareTag("Obstacle"))
{
isDead = true;
Debug.Log("Game Over!");
}
}
}
```
这个脚本实现了贪吃蛇的基本功能,包括移动、旋转、添加身体节、吃食物和撞到障碍物时游戏结束等。你需要在场景中设置好贪吃蛇头、身体和食物的Prefab,并将其分别赋值给snakeHeadPrefab、snakeBodyPrefab和foodPrefab变量。还需要在场景中添加障碍物,并将其标记为"Obstacle" Tag。
