为什么三.PointLightHelper在我的代码中不起作用？

Question

The line scene.add(new THREE.PointLightHelper(bluePoint, 3)); does not work in my code, which is 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));

I have added the libraries: Projector.js , CanvasRenderer.js , stats.min.js and three.min.js

But it does work if I remove the line:

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

Why? Is there another way to increase the PointLight size in three.js without the THREE.PointLightHelper ?

Answer 1

Did you check your console?

scene.addLight is not a function.

You want scene.add(bluePoint)

This runs for me on r71.
