Adding moveable lights – flashlight, part 1

Now we have an understanding of how these lights work, but so far, they've all been static, non-moving. However, in certain instances, we may want the lighting to change while the game is going on. Let's do that by creating a moving light, in a similar manner to a flashlight!

Getting ready

Before we start working, we should have the NightScene level opened. This is provided in the Example Code folder for this chapter that you can get off of Packt's website.

The NightScene level

Note

This level is a quick example of a night environment with the lighting reduced significantly. For more information on creating ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
