Three.js change light intensity dynamically
提问by Austin Best
Is there a way that i have not seen to change the light intensity of directional lights on the fly? Or even ambient light?
有没有一种我没有见过的方法可以即时改变定向灯的光强度？甚至环境光？
ambientLight = new THREE.AmbientLight(0xffffff);
scene.add(ambientLight);
directionalLightL = new THREE.DirectionalLight(0xffffff, dLight, 0);
directionalLightL.position.set(dlpX, dlpY, dlpZ);
scene.add(directionalLightL);
So that is done initially to render, but how can i change just one specific lights intensity afterwards? Remove/re-add the light? Find it in the dom and change it? Something in the API i have not noticed?
所以这最初是为了渲染而完成的，但是我之后如何只改变一个特定的灯光强度？移除/重新添加灯光？在dom中找到并更改它？我没有注意到 API 中的某些内容？

To change the intensity for a DirectionalLight, SpotLight, PointLight, or AmbientLight, you just set it:
要更改DirectionalLight, SpotLight, PointLight, 或的强度AmbientLight，您只需设置它：
light.intensity = 0.5;
You can change the light color like so:
您可以像这样更改灯光颜色：
light.color.setHex( 0xff0000 );
See Color.jsfor other ways to set a color.
有关Color.js设置颜色的其他方法，请参阅。
