我有一个单词数组,我只想在经过一定的秒数后才在数组中显示以下元素。当我遍历每个元素时,draw有效地显示了每个元素,但同时也这样做。如何延迟此过程?
这是当前代码的样子:
=SUM(A{start}:A{end})/60/60
非常感谢您的帮助!

要在单词之间添加延迟,以使所有单词不会同时显示,则可以按索引访问数组,并根据帧数增加索引。
let x = 0;
let speed = 3;
let words = ['hello', 'this', 'is', 'a', 'test'];
let wordIndex = 0;
function setup() {
createCanvas(200, 100);
frameRate(10);
fill(0, 102, 153);
textSize(32);
}
function draw() {
background(255);
// increment the word index every tenth frame
if (frameCount % 10 === 0){
wordIndex++;
}
// when we reach the end of the array reset x and wordIndex
if (wordIndex === words.length){
wordIndex = 0;
x = 0;
}
var word = words[wordIndex];
text(word, x, height/2);
x += speed;
}
