在游戏中使用按钮逃脱延迟

Question

我的一段游戏代码有问题。我想知道，如果我按下按钮，如何打破时间延迟。

最后，游戏会在 LCD 上显示您的最终得分 10 秒。并返回等待开始。我想保持原样 - 我唯一想包括的是，如果我在这 10 秒内按下按钮，我希望它立即返回等待开始。

功能代码在这里

void DrawGameScore()
{   //&amp;RFONT_8X12 &amp;RFONT_16X26
    //char key;
    //key = KBD_GetKey();
    char txt[10];
    UG_FontSelect(&amp;RFONT_16X26);
    UG_SetForecolor(C_WHITE);
    switch (level){
        case 1:

            UG_PutString(60,130,"Peasant Score:");
            sprintf(txt,"%d",score);
            UG_PutString(120,160,txt);
            _delay_ms(10000);
            break;
        case 2:
            UG_PutString(60,130,"Knight Score:");
            sprintf(txt,"%d",score);
            UG_PutString(120,160,txt);
            _delay_ms(10000);
            break;
        case 3:
            UG_PutString(60,130,"Queen Score:");
            sprintf(txt,"%d",score);
            UG_PutString(120,160,txt);
            _delay_ms(10000);
            break;
        case 4:
            UG_PutString(60,130,"King Score:");
            sprintf(txt,"%d",score);
            UG_PutString(120,160,txt);
            _delay_ms(10000);
            break;
        case 5:
            UG_PutString(60,130,"God Score:");
            sprintf(txt,"%d",score);
            UG_PutString(120,160,txt);
            _delay_ms(10000);
            break;
    }
    //UG_PutString(60,130,"Final Score:");

    //sprintf(txt,"%d",score);


    //UG_PutString(120,160,txt);
    //_delay_ms(1000);
}

游戏结束后，此功能会根据您的等级得出分数。在下一个函数中，我调用了 drawgamescore 函数，它位于 dsip_end_score makro.

int EndOfGame()
{
    char key;
    //static int state;
    int result = 1;
    key = KBD_GetKey();

    display_msg = DSIP_END_SCORE;
    if (key == BTN_OK){
        //display_msg = DISP_REFRESH_ALL;
        //display_msg = DSIP_END_SCORE;
        return result;
    } 
    return result;
}

这是主要的游戏功能

void Game()
{
    static int state;
    int result;

    switch (state)
    {
        case 1: //waiting for the game start
            result = WaitForStart();
            if (result == 1) state++;
            break;
        case 2: //Play the game
            result = PlayTheGame();
            if (result == 1) state++;
            break;
        case 3: //Display the score
            result = EndOfGame();
            if (result == 1) state=0;
            break;
        default: //0 or unknown value: reset the game
            state = 1;
            break;
    }
}

谢谢。

我试过了

    return result;

我找到了解决办法！

如果有人感兴趣，这是代码。

int EndOfGame()
{
    int result = 0;
    char key;
    static uint32_t timeStamp;

    static int state = 0;
    display_msg = DISP_REFRESH_ALL;

    switch (state)
    {
        case 0: //Show end score

            display_msg = DSIP_END_SCORE;
            timeStamp = GetSysTick();

            state++;
            break;
        case 1: //read keys after 2 seconds
            if (Has_X_MillisecondsPassed(2000, &timeStamp)
            {
                state++;
                KBD_flush();
                break;
            }
            break;
        case 2:
            key = KBD_GetKey();
            if (key != 0)
            {
                switch (key)
                {
                    case BTN_OK:
                    state = 0;
                    result = 1;
                    break;
                }
            }
             //finish after 10 seconds
            if (Has_X_MillisecondsPassed(10000, &timeStamp))
            {
                result = 1;
                state = 0;
                break;
            }
            break;
    }
    return result;
}

如果您想了解

Has_X_millisecondsPassed();
