Lab 5 — Locomotion Technique Implementation

Thu, 05 Feb 2026 00:00:00 +0000

This post documents the full implementation process of IGD301 Lab Homework 5: taking my locomotion concept from previous assignments and turning it into a working Unity system inside the course-provided parkour scene.

For this lab, all core gameplay locomotion behavior is centralized in LocomotionTechnique.cs, including movement gating, arm-swing power detection, speed mapping, jump, respawn, stage triggers, and coin collection.

1. Goals and Scene Constraints

This assignment is not a generic locomotion demo. It has to work in the official parkour route, which immediately imposes three constraints:

Lecture Homework 4: Final Presentation — Power-Based Arm-Swing Locomotion

This post covers the full content of my final locomotion presentation, organized into three parts: scenario and design goals, system mechanisms, and user evaluation.

Scenario & Challenges

The project scenario is a fixed VR parkour course: a timed race track where you collect coins along the way. The course has multiple checkpoints, continuous curves, and some coins floating above ground level.

The final section of the course is particularly important: several coins sit visibly above the ground, making pure horizontal locomotion insufficient. This constraint directly shaped the locomotion design, which must include some form of vertical movement.

Lecture Homework 3: User Evaluation — Power-Based Arm-Swing in Practice

The goal of HW3 is to run a small-scale user evaluation of my locomotion technique. I recruited two participants and joined as the third myself. Each of us ran the parkour course for three full rounds, recording objective performance data and subjective ratings to see how the system holds up in real users’ hands.

Evaluation Design

Why Evaluate at All

As the developer, I know the system too well. I know every parameter, the optimal entry angle for each curve, what swing cadence maps to what speed. But all of that was accumulated over dozens of iterative test sessions. A first-time user’s experience could be entirely different.

Lecture Homework 2: Locomotion Pitch — Gait-Based Arm-Swing for VR Parkour

Wed, 10 Dec 2025 00:00:00 +0000

The goal of this homework is to design a locomotion technique that fits the provided VR parkour scene better than the default. The level is a fixed route with banner timing checkpoints and lots of collectible coins. The key twist is that not all coins are on the ground—some are floating slightly above it. So it’s not just about moving fast. You also need to stop on demand, make small position corrections, and occasionally perform a small vertical action to reach elevated coins.
