Static p5_sys::global::spotLight

pub static spotLight: SpotLightInternalType

Creates a spotlight with a given color, position, direction of light, angle and concentration. Here, angle refers to the opening or aperture of the cone of the spotlight, and concentration is used to focus the light towards the center. Both angle and concentration are optional, but if you want to provide concentration, you will also have to specify the angle.

A maximum of 5 spotLight can be active at one time

Examples

function setup() {
  createCanvas(100, 100, WEBGL);
}
function draw() {
  background(0);
  //move your mouse to change light position
  let locX = mouseX - width / 2;
  let locY = mouseY - height / 2;
  // to set the light position,
  // think of the world's coordinate as:
  // -width/2,-height/2 -------- width/2,-height/2
  //                |            |
  //                |     0,0    |
  //                |            |
  // -width/2,height/2--------width/2,height/2
  ambientLight(50);
  spotLight(0, 250, 0, locX, locY, 100, 0, 0, -1, Math.PI / 16);
  noStroke();
  sphere(40);
}
