1. A computer-implemented method comprising: as implemented by an interactive computing system configured with specific computer-executable instructions, determining an initial position of a character displayed in a video game; determining a target pose for the character; detecting a collision with the character has occurred in the video game; and in response to detecting the collision: updating a ragdoll representation, of the character associated with the initial position of the character to obtain a final pose based at least in part on the target pose and the collision; extracting a set of reference features from the final pose; identifying a motion capture frame from a set of motion capture frames as a match to the set of reference features; and causing the motion capture frame to be output for display in the video game.
