Question

你好我的团结c＃安卓游戏平台是在玩家面前随机生成的。此脚本中的if语句会检查最近的平台是否是我正在查找的平台（左，右，上，下），并且播放器未按正确方向滑动strike设为1.

每当strike等于1时，我希望我的生命价值下降一。当我玩游戏时strike = 1，生命立即降至0，但我希望它们从3开始当strike= 1时为2，如果为strike = 1，则为2，最后为1，为0。

以下是if语句

void Start()
{
    lives = 3;
    theScoreManager = FindObjectOfType<ScoreManager>();
}

// Update is called once per frame
void Update()
{
    if (strike == 1)
    {
        lives = 2;
    }

    if (strike ==1 && lives == 2)
    {
        lives = 1;
    }

    if (strike == 1 && lives == 2)
    {
        lives = 0;
    }

这是整个c＃脚本

using UnityEngine;
using System.Collections;

public class SwipeChecker : MonoBehaviour
{

    public float maxTime;
    public float minSwipeDistance;

    float startTime;
    float endTime;

    public bool rightSwipe;
    public bool upSwipe;
    public bool downSwipe;

    public int strike;
    public int lives;
    public int livesToGive;

    public GameObject closestPlatform;

    private ScoreManager theScoreManager;

// Use this for initialization

    gos = GameObject.FindGameObjectsWithTag("platform");


    GameObject closest = null;
    float distance = Mathf.Infinity;
    Vector3 position = transform.position;
    foreach (GameObject go in gos)
    {
        Vector3 diff = go.transform.position - position;
        float curDistance = diff.sqrMagnitude;
        if (curDistance < distance)
        {
            closest = go;
            distance = curDistance;
        }
    }

    return closest;

    }

    livesToGive = lives;

    }

    if (Input.touchCount > 0)
    {
        Touch touch = Input.GetTouch(0);

Answer 1

您在strike的开头将Update设置为0。

Answer 2

您将strike==1设置为更新中的第一件事，这样检查if (strike==1){ lives-- //decrement lives by one strike=0 //reset strike }的所有if语句将始终为false。你需要在测试后将反击设置回0，而不是之前。

另外那些if语句是坏的，第一个会将生命减少到2，这将使第二个生命点火并将生命设置为1，第三个永远不会，因为它也会检查2的生命。也许是这样的事情？

else if

我不是团结专家，但这应该适用于任何C＃代码。如果你不想按照我的方式使用if语句，你需要使用int main (void) { FILE *outFile; //The output file (encrypted) /* A 256 bit key */ unsigned char *key = (unsigned char *)"01234567890123456789012345678901"; /* A 128 bit IV */ unsigned char *iv = (unsigned char *)"01234567890123456"; int fd; struct stat sb; void * memblock; fd = open("result0.jpg",O_RDONLY); outFile=fopen("result0enc.jpg","wb"); fstat(fd, &sb); printf("Size: %lu\n", sb.st_size); unsigned char decryptedtext[sb.st_size]; int decryptedtext_len, ciphertext_len; /* Initialise the library */ ERR_load_crypto_strings(); OpenSSL_add_all_algorithms(); OPENSSL_config(NULL); memblock = mmap(NULL, sb.st_size,PROT_READ, MAP_SHARED, fd, 0); if (memblock == MAP_FAILED) { close(fd); perror("Error mmapping the file"); exit(EXIT_FAILURE); } ciphertext_len = encrypt((unsigned char *)memblock, sb.st_size,key,iv,ciphertext); fwrite( ciphertext,1, sb.st_size,outFile); if (munmap(memblock, sb.st_size) == -1) { perror("Error un-mmapping the file"); /* Decide here whether to close(fd) and exit() or not. Depends... */ } close(fd); fclose(outFile); EVP_cleanup(); ERR_free_strings(); return 0; }并在条件链的末尾重置strike，而不是之前。

Answer 3

Strike永远不会是1，因为每次更新都会将其重置为零

void Update()  
{  
   strike = 0;  
   ...

打击功能无法正常工作
