注冊觸摸移動後,將調用p5.js中的touchMoved()函數。如果未定義touchMoved()函數,則將調用mouseDragged()函數(如果已定義)。
用法:
touchMoved([Event])
以下示例程序旨在說明p5.js中的touchMoved()函數:
示例1:
let valueX;
let valueY;
function setup() {
// Create Canvas of size 500*500
createCanvas(500, 500);
}
function draw() {
// set background color
background(200);
fill('green');
// set text and text size
textSize(25);
text('Hold and Move to change color', 30, 30);
// fill color according to touchStarted()
fill(valueX, 255 - valueY, 255 - valueX);
// draw ellipse
ellipse(mouseX, mouseY, 115, 115);
}
function touchMoved() {
valueX = mouseX % 255;
valueY = mouseY % 255;
}
輸出:

// draw rectangle
rect(mouseX, mouseY, 115, 115);
fill(valueY, 255 - valueX, 255 - valueX);
rect(mouseX, mouseY + 115, 115, 115);
fill(255 - valueY, 255 - valueX, 255 - valueY);
rect(mouseX - 115, mouseY, 115, 115);
fill(255 - valueY, 255 - valueY, 255 - valueY);
rect(mouseX - 115, mouseY + 115, 115, 115);
}
function touchMoved() {
valueX = mouseX % 255;
valueY = mouseY % 255;
}
