Development Of Gaggle Brains

Gaggle Brains is an enhanced version of our 2019 entry 'Zombie Gaggle', for the GMTK gamejam. In the new game we aim to expand what we can do with Active Ragdoll characters and Procedural Animation, to see if relatively large crowds can be physically driven, to mimic naturalistic movement - so they bump, collide, pull and drag amongst each other. Coding is used to give the movements enough structure to seem like dynamic animated characters, rather than flailing dolls.

Developing and refining the animation of active ragdolls, in order to add more complexity to the interactions the physical characters can have in basic gameplay, is our current obsession as a studio, and is something we hope to continue developing in our next titles
