A research project exploring grappling hooks across video games — why the mechanic is so prevalent, how it has evolved, and what makes it feel good. Created as part of a Year 3 BSc project combining written research with a working implementation in Unreal Engine 4.
Grappling hooks have appeared in video games for over 40 years. Despite this, there has been very little research into why the feature keeps appearing and what makes each implementation feel different. The mechanic has become something of a sixth sense for experienced players — as familiar as using WASD.
Implementation
As part of the research, a range of grappling hook implementations were built in Unreal Engine 4 Blueprint, varying in physics behaviour, feel and control. A group of game players tested each variant and provided feedback on where their preferences lay.
