p5.js 加速Z 变量
AccelerationZ 系统变量负责设备(平板电脑或手机)沿 Z 轴的加速度。可以在draw()函数中使用,在坐标的Z轴上加速设备。
它的值表示为米每秒平方。
句法:
accelerationZ
示例 1:
Javascript
// Move a touchscreen device to register
// acceleration changes.
function draw() {
background(220);
fill('blue');
//Set the variable.
square(width, height, accelerationZ);
}
Javascript
// Move a touchscreen device to register
// Acceleration changes.
function setup()
{
createCanvas(400,400)
}
function draw() {
background(0, 50);
fill('green');
textAlign(CENTER,CENTER);
textSize(50);
// Convert the acceleration into integer when
// device is moved along x axis.
text(int(accelerationZ),windowWidth/2,windowHeight/2);
}
输出:
