I have a parent class called Entity and another class named CrawlerTurret which derives from the parent class Entity. When I go to compile and get the object file of the files, however, g++ informs me that there is a member function in there that is not of class Entity. Here's some code and what I'm typing in:
CrawlerTurret.h - FULL
CrawlerTurret - SNIPPET
Entity.h - FULL
Entity.cpp - SNIPPET
In Terminal:
... But update and everything else in there is fine??
