Gamepad: axes property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.
The Gamepad.axes property of the Gamepad
interface returns an array representing the controls with axes present on the device
(e.g., analog thumb sticks).
Each entry in the array is a floating point value in the range -1.0 – 1.0, representing the axis position from the lowest value (-1.0) to the highest value (1.0).
Value
An array of numbers.
Examples
js
function gameLoop() {
const [gp] = navigator.getGamepads();
let a = 0;
let b = 0;
if (gp.axes[0] !== 0) {
b -= gp.axes[0];
} else if (gp.axes[1] !== 0) {
a += gp.axes[1];
} else if (gp.axes[2] !== 0) {
b += gp.axes[2];
} else if (gp.axes[3] !== 0) {
a -= gp.axes[3];
}
ball.style.left = `${a * 2}px`;
ball.style.top = `${b * 2}px`;
const start = requestAnimationFrame(gameLoop);
}
