There's a 'Lighting" example (do File/New and type 'lighting' in the search box) if you haven't already seen it. Might get you started.
Develop games in your browser. Powerful, performant & highly capable.
There are several ways.
The "Shadow Caster" behavior should be helpful. You might also check the "Ambient Light"-Example included with the installer.
Edit: Sorry —
