What Is It?

Coma - Component Manager is a Unreal Engine 4 plugin which enables C++ and Blueprint developers alike to model component dependencies more easily and efficiently.

Idea & Use Case

While we were working on our new game Knights of Cathena we used components extensively. We used them in the context of the SOLID principle which allows each component to only have a single responsibility and reference another component for another responsibility if a call to it is needed to.

The approach we took was very combersome, we abstracted the logic to fetch the needed component references for another responsibility within a method and printed out a error and halted the game if the needed component couldn't be found on the parent actor. You can imagine that this took a lot of boilerplate code and maintenance, because of that we lost our precious iteration time that we all need to create great gameplay features.

So, we sat out to create a better and less boilerplate solution that would not only work for our C++ gameplay code but for Blueprint as well. And Coma raised from the ashes!
