Ah interesting. See I was using Rama’s example: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official... and I realized that setting the (edit: didn’t mean to use the word virtual here) member functions to static allowed me to then do what you said (I was tripping a break trying to create an instance of the static lib class so I had to do some digging). Would you be so kind as to explain as to why making it a virtual is useful and what does the ‘~’ do in that case as a prefix?
