Gamepad.axes
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.
Examples
function gameLoop() {
if(navigator.webkitGetGamepads) {
var gp = navigator.webkitGetGamepads()[0];
} else {
var gp = navigator.getGamepads()[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";
var start = rAF(gameLoop);
};
Value
An array of double
values.
