Core Grappling Mechanic

Blueprint Implementation

A foundational traversal system enabling dynamic grappling from character to target

This project involved designing and scripting a functional grappling mechanic in Unreal Engine 5, built during the early stages of my development journey. Created for a master’s degree student showcase project, this prototype laid the groundwork for the final system, later remastered by the team. The mechanic allowed the player character to launch a grapple cable from their hand to a designated target point, triggering a calculated, physics-informed pull across the level.

Key Design Highlights

  • Designed the initial grappling system to detect and connect to target points using trace logic.
  • Calculated custom flight arcs using distance vectors and velocity estimation for a smooth traversal feel.
  • Balanced functionality and flexibility to allow adaptation by senior-level designers for the final showcase.
  • Translated early paper math and logic planning into a working Blueprint prototype in less than a week.

Tech Stack

Engine

Unreal Engine 5

Tools

Blueprints, Official Unreal Documentation

Development Timeline

Total project duration: 2 months
Initial prototype developed in 1 week across two phases — paper math design and blueprint implementation.

Programming Focus

  • Built the grappling system entirely in Blueprints, using event-driven logic, vector math, and interpolation.
  • Researched and referenced Unreal’s official documentation to overcome early technical gaps.
  • Collaborated with experienced teammates for iteration and incorporated feedback on usability and timing.

Results

  • Integrated into the final showcase project for a Game Design Master’s cohort.
  • Strengthened my understanding of vector math, trace systems, and traversal mechanics.
  • Marked a key milestone in my Blueprint learning journey, boosting confidence in functional prototyping.
