description:
Questionmark Industries is a interactive VR experience, in which the player is placed behind a desk with various objects in front of him, that he can interact with. The player has to perform monotonous tasks and has to wonder if there’s more to it than that.
In this project I programmed the entire gameplay and the events that happen around the player. I also tested it on the Gear VR throughout development and iterated on it.
Made in Unity3D with C# for the Samsung Gear VR
Started: April 2017
Finished: June 2017

This script handles the camera of the player and determines if the player is looking at an interactable object. If he is, the player can click on it with his mouse (or touchpad from the Gear VR) and interact with it.
