The touchMoved() function in p5.js is called when a touch move is registered. If no touchMoved() function is defined, the mouseDragged() function will be called instead if it is defined.
Syntax:
touchMoved([Event])
Below program illustrates the touchMoved() function in p5.js:
Example-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; } |
Output:
