Extend ATriggerBox in Plugin?

Hi all,

Im having some issues extending the ATriggerBox class in a Plugin. Im simply using the default code generated when adding a C++ class via the Unreal Editor.

The errors i receive when attempting the compile come from “EngineBaseTypes.h”. It appears this is due to me including “Engine/TriggerBox.h” in this header. Is there a step i’m missing to include the Engine headersas part of a plugin?
