Safety at Work

Safety At Work is a VR program which teaches users how to better interact with people with disabilities, through a series of scenarios.

State Machine Nodes

To control the flow of the scenarios we used a state machine. I created a tool to edit the state-machine based off of xNode.

For the statemachine, I built custom inspectors which let designers set up logic for the flow of the scenarios. As well as other tools to help the designers with their tasks. The majority of my time on this project was working on this node system.

Physics Pausing

Another interesting problem I had to solve was the ability to pause the scenarios. Since the VR system we were using, had all of it's intereactions be physics based, we had to find a system where we could pause any object in the scenario, but keep the player updating so that they can interact with the menu. To solve this whenever the player would enter the pause menu I would run a second physics simulation which would allow the player to continue interacting with menu items.
