I'm not 100% sure if this is the right place to ask about my problem, since it may be related to visual studio and not my c++ code at all, but validation that my code is correct would be helpful nonetheless.
When I try to build I expect the PipeObstacle class to have access to Drawable's default constructor so it can add itself to the _objects unordered set that my Game class loops through to call all draw() functions and render the game. However, I get a linker error when the constructor for PipeObstacle attempts to reference Drawable() in it's initializer list. I have already tried using hpp only and inline static, and although I am using a two project setup with Drawable being held in a shared project, merging the projects together did not solve the issue.
Error:
