Generally C# is a very strongly typed language and usually lists allow only one defined data type. Using ArrayList, however, we can get around this restriction to some extent.

Screenshots can be created very easily in Unity using the ScreenCapture class respectively the CaptureScreenshot method. You can use the class defined below. Just create a new script CaptureScreenshot.cs and paste the code there. Then you just have to attach the new MonoBehaviour to a GameObject. You can select the folder and the key afterwards simply inside the Inspector. Screenshots will be saved in your system folder Pictures.

Creating a Singleton in Unity is pretty simple. It basically works relatively similar to the procedure in vanilla C#. With the small difference that we basically don't have to worry about initialization (at least with MonoBehaviours).

Sometimes you just want to store some random value. For this I wrote the RuntimeStorage class. It serves me in some games as a naive cache for a couple of less important values.

Creating a Singleton is relatively simple. First we create a static variable _instance. In addition, we create a property Instance. We will use it later to access the Singleton. In addition, a new instance of the class is provided there, if none should exist yet. This way we also ensure that the singleton is initialized at exactly the right moment. Namely, only when we need it.

The PlayerPrefs class provides a simple way to persistently store scalar data in Unity. I like to use my own abstraction layer at this point in case I want to change the storage approach at some point. Also, the layer harmonizes very well with the RuntimeStorage class I developed.

You can change the assigned IP address of your computer by editing the file /etc/network/interfaces. Search there for your primary Ethernet controller (usually eth0). Change the value from dhcp to static. Then you can specify address (IP address) and gateway (usually your router). Then restart the network or computer. Tested under Ubuntu and Rasbperry Pi OS.

To create a user and a database in MySQL, it doesn't take many commands. First of all, the database must be created.
