Unity中FPS类小游戏的简单制作

1.摄像机放Player上，射线机代码

using UnityEngine;
using System.Collections;

public class Camera : MonoBehaviour {

public GameObject player;
private Vector3 rot = new Vector3(0, 0, 0);
public float speed;
// Use this for initialization
void Start() {

}

// Update is called once per frame
void Update() {
Move111();
}

void Move111() {
float MouseX = Input.GetAxis("Mouse X") * speed;
float MouseY = Input.GetAxis("Mouse Y") * speed;

rot.x = rot.x - MouseY;
rot.y = rot.y + MouseX;
rot.z = 0;
transform.eulerAngles = rot;
player.transform.eulerAngles = new Vector3(0, rot.y, 0);

if (rot.x <= -70) {
transform.eulerAngles = new Vector3(-70, rot.y, 0);
}
if (rot.x >= 10) {
transform.eulerAngles = new Vector3(10, rot.y, 0);
}
}
}


2.僵尸身上的代码
using UnityEngine;
using System.Collections;

public class XunLu : MonoBehaviour {
GameObject tar;
public float speed;
float dis;
Animator anim;
//NavMeshAgent mynav;
// Use this for initialization
void Start() {
anim = GetComponent<Animator>();
tar = GameObject.Find("Ppp");
}

// Update is called once per frame
void Update() {
/* mynav.*/ //此处不可以，寻找的是mynav
GetComponent<NavMeshAgent>().SetDestination(tar.transform.position);
GetComponent<NavMeshAgent>().speed = speed;
Donghua();
}

void Donghua() {
dis = Vector3.Distance(transform.position, tar.transfor
4000
m.position);

if (dis <= 1.5f + 0.5f) {
anim.SetBool("New Bool", true);
} else {
anim.SetBool("New Bool", false);
}

}
}
3.Player身上的配合角色控制器的代码
using UnityEngine;
using System.Collections;

public class Ppp : MonoBehaviour {
public float speed = 6.0F;
public float jumpSpeed = 8.0F;
public float gravity = 20.0F;
private Vector3 moveDirection = Vector3.zero;
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;

}
moveDirection.y -= gravity * Time.deltaTime;
controller.Move(moveDirection * Time.deltaTime);
}
}4.游戏控制器代码
using UnityEngine;
using System.Collections;

public class GameCotroller1 : MonoBehaviour {
public GameObject[] ZuoBiao;
public GameObject Enemy;

public GameObject Q1;
public GameObject Q2;
int i = 0;
// Use this for initialization
void Start() {
StartCoroutine("Spawn");
}

// Update is called once per frame
void Update() {
Shexian();
HuanQ();
}

IEnumerator Spawn() {
while (true) {
int i = Random.Range(0, 4);
Instantiate(Enemy, ZuoBiao[i].transform.position, ZuoBiao[i].transform.rotation);
yield return new WaitForSeconds(Random.Range(2.0f, 3.0f));

}
}
public void Shexian() {
RaycastHit hit;
Vector3 rayPosition = new Vector3(Camera.main.pixelWidth * 0.5f, Screen.height * 0.5f);
Ray ray = Camera.main.ScreenPointToRay(rayPosition); //定义准备一条射线
if (Input.GetMouseButtonDown(0)) {
Physics.Raycast(ray, out hit);
if (hit.transform.tag == "Enemy") {
hit.transform.gameObject.GetComponent<Animator>().SetTrigger("New Trigger");
hit.transform.gameObject.GetComponent<NavMeshAgent>().Stop();
Destroy(hit.transform.gameObject, 3.0f);
hit.transform.gameObject.GetComponent<CapsuleCollider>().enabled = false;

}
}
}

void HuanQ() {
if (Input.GetKeyDown("q")) {
i = i + 1;//1 2
if (i % 2 != 0) {
Q1.SetActive(false);
Q2.SetActive(true);
print("1111");
}
if (i % 2 == 0) {
print("2222");
Q2.SetActive(false);
Q1.SetActive(true);
}
}
}
}
