Ragdoll
Character bodies switch from animation to physics simulation — usually on death or impact — flopping, tumbling, and reacting to forces realistically. Ragdoll physics replaced canned death animations with dynamic, situation-specific reactions: a body flung by an explosion or crumpling down stairs looks different every time. Designers use ragdolls for visceral, believable impact feedback, for emergent comedy and spectacle (a genre unto itself in physics sandboxes), and to avoid the uncanny repetition of fixed death animations. Key decisions: blend timing (the pop from animation to ragdoll can look jarring — modern games blend or use partial ragdoll), performance budget (many simultaneous ragdolls are expensive), constraint tuning to avoid spasming or clipping through geometry, and whether ragdolls are purely cosmetic or physically interactive. Pitfall: poorly-constrained ragdolls are a classic source of unintentional hilarity and jank — bodies vibrating, launching into the sky, or tangling in scenery — which undermines tone in a serious game, so joint limits and collision handling need real polish.
