Rope Simulation in 'Uncharted 4' and 'The Last of Us 2'

Jaroslav Sinecky  (Game programmer, Naughty Dog, Inc.)

Pass Type: All Access Pass, Core Pass

Topic: Programming

Format: Session

Vault Recording: TBD

Audience Level: N/A: I prefer to present live on-site but I am open to delivering a virtual presentation

For Uncharted 4 a new rope technology had to be developed to allow for Drake's grapple rope and jeep winch to bend and wrap around collision while setting a new high bar for grapple rope presentation in games. In The Last Of Us 2 this technology was taken a step further to support rope puzzles where the player has the freedom to throw 14m of rope into the environment and pick it up at any point. This presentation will go over the history of development of this technology and the major challenges encountered on the way. Then it will dive into some details of the soft body simulation as well as the technique used to solve the problem of taut rope wrapping around collision.


Attendees will get a glimpse into the long history of developing the rope technology at Naughty Dog, will learn about the major challenges encountered on the way and the techniques used to overcome these challenges.

Intended Audience

This presentation is targeted towards game programmers but should be accessible for any technically oriented developers interested in the subject. Some basic math and a notion of elemental mechanical laws will be helpful for understanding details of some of the techniques but are not essential.
