Question

以下是我的代码的简要概述：

void setup() {...}

void draw() {

//Two images horizontal to each other blink alternately. //After 4 blinks function vertical_blink() is called

}

void vertical_blink() { //Two images blink vertically

}

问题是垂直图像永远不会闪烁。程序回到水平闪烁。如何使程序保持垂直闪烁？我试着延迟，而且为了。所有这些都弄乱了时机。代码在这里。

PImage water;
PImage waterh;
PImage home;
PImage homeh;

int t;
int flag = 0;

void setup() {
    size(1800, 1128);
    background(0);
    home = loadImage("C:\\IoT\\SWSG\\FinalStages\\ProcessingPics\\home.jpg");
    homeh = loadImage("C:\\IoT\\SWSG\\FinalStages\\ProcessingPics\\homeh.jpg");
    water = loadImage("C:\\IoT\\SWSG\\FinalStages\\ProcessingPics\\water.jpg");
    waterh = loadImage("C:\\IoT\\SWSG\\FinalStages\\ProcessingPics\\waterh.jpg");
    t = millis() / 1000;
}

void draw() {
    background(0);
    image(home, 100, 25, 200, 200);
    image(water, 350, 25, 200, 200);
    if ((millis() / 1000) - t >= 3) {
        flag++;
        t = millis() / 1000;
    }
    if (flag == 0)
        image(homeh, 100, 25, 200, 200);
    if (flag == 1)
        image(waterh, 350, 25, 200, 200);
    if (flag == 2)
        new_section();
}

void new_section() {
    background(255);
    int t2 = millis() / 1000, flag2 = 0;
    image(home, 100, 25, 200, 200);
    image(water, 100, 250, 200, 200);
    if (millis() / 1000 - t2 >= 3) {
        flag2++;
        t2 = millis() / 1000;
    }
    if (flag2 == 0)
        image(homeh, 100, 25, 200, 200);
    if (flag2 == 1)
        image(waterh, 100, 250, 200, 200);
    if (flag2 == 2)
        flag2 = 0;
}

您是否尝试过使用frameCount代替millis()？所以你的柜台可能会喜欢这样的东西

void draw() {

     if (frameCount % 4 == 0) {
         // Called every 4 frames
     }

     if (frameCount % 4 == 2) {
         // Called every 4 frames, but 2 frames offset
     }

}

我试图调用另一个函数，但控件很快就会回到draw（）
