The Office features FPS gameplay mechanics developed using Unreal Engine (C++/Blueprints)
The purpose of this project was to implement a common FPS mechanic which the player could choose an object to interact with in the game scene. Using the rendering effect of mesh render outline it will be very easy to distinguish which object would be interactable. Using C++ and exposing to blueprints, it would be very productive for a game designer to set in the unreal editor that feature for selected objects.
To outline the mesh render of objects in game level, a post process volume material was created to detect objects edges lines as common in cel shading effects. In the material, using the custom depth buffer, stencil values determine whether the objects color outline changes or not. The appearance of the objects silhouettes are in:
For each interactable object, hover and unhover events enables on and off respectively the custom render depth modifying the outline color appearance.
Hover and Unhover events are blueprint implementable events set in base class Interactable.h code:
To help identify interactables objects in the game level, the player has the aim pointer HUD to aid the player where his target is pointing to. UX best practices tell us that feedback should be constant in games. That's why this pointer is always active.
The default behavior of the Aim Pointer aids the player where its target is looking at.
The aim pointer follows the FPS controller camera rotation as expected.
When the game starts, it is created in Blueprints and added to the game screen.
When identifying an interactable in the game level, the aim pointer interface changes to indicate that the interaction is enable to happen on the spotted object. A new game interface is switched in this moment.
