Basic Unity Concepts for VR Development

Define stereoscopic vision, how VR differs from other XR, tracking methods, 3DoF versus 6DoF, and VR input; use the Package Manager and the XR Interaction Toolkit; import and modify assets and Prefabs; use the Transform component to position, rotate, and scale; identify the correct interface windows; and manage components in the Inspector.

Building a Scene for VR

Apply preplanning techniques such as design documents, flow charts, animatics, storyboarding, concept art, greyboxing, and proportional level scaling; implement environment design with finalized 3D assets; and identify when to use Baked versus Realtime lighting.

UX Implementation for VR

Create a World Space UI using Canvas, Button, Image, Text, and the Event System; determine the Colliders, XR Grab Interactable, and Rigidbodies needed to manipulate objects; identify locomotion types including degrees of freedom, teleportation, and turning; design optimal interactions for health and safety; and differentiate 2D and spatial audio.

Scripting with Unity

Select basic C# using properties, variables, methods, data types, and binary operators; choose the right Unity structure such as Vector3, GameObject, Collider, Rigidbody, or AudioSource; and handle collision or trigger Enter, Stay, and Exit events.

Troubleshooting and Playtesting

Identify areas to troubleshoot including Static objects, missing Colliders or Rigidbodies, and Is Trigger, Is Kinematic, or Use Gravity settings; recognize Console log types; fix errors such as null references and syntax errors; and apply optimizations including occlusion culling, removing unused objects, and level of detail (LOD).
