What could be causing the three.PointLightHelper to fail in my script?

I am encountering an issue with the line of code 

scene.add(new THREE.PointLightHelper(bluePoint, 3));
in my code snippet below:

var bluePoint = new THREE.PointLight(0x0033ff, 100, 500);
bluePoint.position.set( 500, -500, 25 );
scene.addLight(bluePoint);
scene.add(new THREE.PointLightHelper(bluePoint, 3));

Even though I have included the libraries: Projector.js, CanvasRenderer.js, stats.min.js, and three.min.js

The code works fine if I remove the line:

scene.add(new THREE.PointLightHelper(bluePoint, 3));

Why is this happening? Is there an alternative method to increase the size of PointLight in three.js without using THREE.PointLightHelper?

Answer №1

Have you taken a look at your console?

The error message "scene.addLight is not a function" is coming up.

Try using scene.add(bluePoint) instead.

I have successfully run this code on version r71.
