p5.js | unchar()函数

p5.js 中的unchar()函数用于将单个字符串转换为其对应的整数表示。此函数与 char()函数正好相反。

句法:

unchar(value)

参数:此函数接受单个参数,该值将被转换为其相应的整数表示。此值将是任何单字符字符串或单字符数组。

返回值:返回单字符串转换后的整数表示。

下面的程序说明了 p5.js 中的 unchar()函数:

示例 1:本示例使用 unchar()函数将单个字符串转换为其对应的整数表示。

function setup() { 
   
    // Creating Canvas size
    createCanvas(600, 230); 
} 
   
function draw() { 
       
    // Set the background color 
    background(220); 
     
    // Initializing some values
    let Value1 = "A";
    let Value2 = "a";
    let Value3 = "B";
    let Value4 = "C"; 
    let Value5 = "z";
     
    // Calling to unchar() function.
    let A = unchar(Value1);
    let B = unchar(Value2);
    let C = unchar(Value3);
    let D = unchar(Value4);
    let E = unchar(Value5);
     
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting integer representation
    text("Integer representation of alphabet A is: " + A, 50, 30);
    text("Integer representation of alphabet a is: " + B, 50, 60);
    text("Integer representation of alphabet B is: " + C, 50, 90);
    text("Integer representation of alphabet C is: " + D, 50, 110);
    text("Integer representation of alphabet z is: " + E, 50, 140);
} 

输出:

    let A = unchar("A");
    let B = unchar("b");
    let C = unchar("y");
    let D = unchar("Y");
    let E = unchar("P");
     
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting integer representation
    text("Integer representation of alphabet A is: " + A, 50, 30);
    text("Integer representation of alphabet b is: " + B, 50, 60);
    text("Integer representation of alphabet y is: " + C, 50, 90);
    text("Integer representation of alphabet Y is: " + D, 50, 110);
    text("Integer representation of alphabet P is: " + E, 50, 140);
}    

输出:
