Infinite Scroll is used with object pooling. Buttons are created by using factory method, also they inherit from BasicButtonBehaviour class. EventManager class is created to handle custom events(publish - subscribe design pattern). Singletons are used most of the time. InputManager is created to handle inputs and trigger events which are changing grid model and make soldiers move wrt this changes. This is a small implementation of MVC pattern. An abstract class is created for buildings just to show implementation of polymorphism. But inheritance will be a better option for our situation. Coroutine is used for soldiers' movement, it is a better option than update because it doesn't work all the time. I also inherited soldiers from militaryUnit class in case of adding more military units (they all will have movement script) like flying soldiers, tanks, horse etc. and add a small script to soldier just to show implementation. Unity's Entity and math class is used in A* path finding algorithms. Resharper is used too.

WASD can be used for camera movement and mouse wheel is used for camera zoom. Left Click for selecting, right click for moving soldiers.
