ProtoPie adds physics-driven interactions and WebXR preview for immersive demos

Gaming · 4 min read

ProtoPie's latest engine upgrade introduces built-in physics primitives—mass, friction, gravity, springs—that designers can apply without scripting. These primitives simplify the creation of tactile micro-interactions like draggable, bouncy cards or momentum-based lists, which previously required complex timing curves or custom equations.

The update pairs physics with a WebXR preview channel: prototypes can be exported as WebXR sessions that run in compatible browsers and standalone headsets. Testers can experience depth, occlusion, and spatial interaction without building a native app. ProtoPie also included new haptics mapping and optional controller input bindings to simulate common headset controllers.

For product teams that straddle app and game UX, the new features reduce iteration time for complex, physics-driven behaviors. Usability testing can now capture more realistic responses to motion and inertia, and handoff notes include measurable parameters designers used, which helps engineers reimplement interactions faithfully.
