controlP5：用于多个RadioButton结果的矩阵/ 2D阵列

Question

我试图询问用户从4组或更多组单选按钮（处理2+）中选择5组按钮。在遇到麻烦的时候，通过从每组按钮中进行选择来创建数组，然后将其填充到矩阵中可以查询元素的列中，并且可以打印2D数组并最终将其写为csv或tab txt文件。

import controlP5.*; 
ControlP5 controlP5; 

RadioButton c0; 
RadioButton c1; 
RadioButton c2; 
RadioButton c3; 

int cols = 5; 
int rows = 4; 
int[][] myArray = new int[cols][rows]; 

void setup() { 
    size(600,650); 
controlP5 = new ControlP5(this); 
    c0 = controlP5.addRadioButton("ch0",60,60) 
       .setSize(20,20) 
       .setItemsPerRow(5) 
       .setSpacingColumn(50)    
       .addItem("c03", 1) 
       .addItem("c04", 2) 
       .addItem("c05", 3) 
       .addItem("c0AM", 4) 
       .addItem("c0AF", 5) 
       ; 
    c1 = controlP5.addRadioButton("ch1",60,80) 
       .setSize(20,20) 
       .setItemsPerRow(5) 
       .setSpacingColumn(50) 
       .addItem("c13", 1) 
       .addItem("c14", 2) 
       .addItem("c15", 3) 
       .addItem("c1AM", 4) 
       .addItem("c1AF", 5) 
       ; 
    c2 = controlP5.addRadioButton("ch2",60,100) 
       .setSize(20,20) 
       .setItemsPerRow(5) 
       .setSpacingColumn(50) 
       .addItem("c23", 1) 
       .addItem("c24", 2) 
       .addItem("c25", 3) 
       .addItem("c2AM", 4) 
       .addItem("c2AF", 5) 

       ; 
    c3 = controlP5.addRadioButton("ch3",60,120) 
       .setSize(20,20) 
       .setItemsPerRow(5) 
       .setSpacingColumn(50)   
       .addItem("c33", 1) 
       .addItem("c34", 2) 
       .addItem("c35", 3) 
       .addItem("c3AM", 4) 
       .addItem("c3AF", 5) 

       ; 
} 

void draw() { 
background(0); 
} 

void controlEvent(ControlEvent theEvent) { 
    if(theEvent.isGroup() && theEvent.name().equals("ch0") || theEvent.name().equals("ch0") ||  theEvent.name().equals("ch2") || theEvent.name().equals("ch3")){ 
    println(theEvent.name()); 
    println(theEvent.arrayValue()); 
    //float t=float(theEvent.arrayValue()); 
    //int[][] = { {float getGroup(),float[] getArrayValue()}, {3,2,1,0}, {3,5,6,1}, {3,8,3,4} }; 
//int cols = 4; 
//int rows = 5; 
//int[][] myArray = new int[cols][rows]; 

// Two nested loops allow us to visit every spot in a 2D array. 
// For every column I, visit every row J. 
//for (int i = 0; i < cols; i++) { 
// for (int j = 0; j < rows; j++) { 
//myArray[i][j] = float(theEvent.arrayValue); 
    } 
}

你在混合不同的东西在一起。你也不需要检查整个数组并存储这些信息。只需更新点击按钮。这里是你的controlEvent

void controlEvent(ControlEvent theEvent) { 

    int cols = 4; 
    int rows = 5; 
    int[][] myArray = new int[cols][rows];  

    switch(theEvent.getId()){ 
    case 0: 
     myArray[0][(int)theEvent.value()-1] = 1; 
     break; 
    case 1: 
     myArray[1][(int)theEvent.value()-1] = 1; 
     break; 
    case 2: 
     myArray[2][(int)theEvent.value()-1] = 1; 
     break; 
    case 3: 
     myArray[3][(int)theEvent.value()-1] = 1; 
     break; 
    } 
    println("==== " + theEvent.getId() + " ==="); 
    println(myArray[theEvent.getId()]); 
} 

新版本要做到这一点简单的开关，你需要ID参数添加到您的所有单选按钮是这样的：

c3 = controlP5.addRadioButton("ch3", 60, 120) 
    .setId(3) 
    .setSize(20, 20) 
    ... 

我不知道你是怎么想究竟使用这个数组让我的实现将它用作局部变量，所以每次调用该事件时它都会被删除，但是可以通过将数组声明为全局变量，然后删除仅更新的列来避免这种情况。
