Creating a Day/Night cycle

If we are creating an open world title or any kind of game where the player is outdoors, one thing that would be nice is the ability to have our world change the time of day at the same rate.

Getting ready

Before we start working, we should have a level created with a Sky_Sphere and a directional light (the default map has this). To be sure, you can use the DayNightCycle-Before map from the example code folder.

How to do it…

Perform the following steps to create a day/night cycle:

As we discussed before, we can use Directional Lights to act like the sun. For our day/night cycle we will want our lighting to change over time, so let's select the DirectionalLightStationary object from the Scene Outliner tab and then from the ...

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.
