Detailed Description

Keeps a ragdoll's bodies in step with whichever is in charge.

The bodies exist, and so simulate, whether or not the ragdoll is active. Inactive, they are kinematic hitboxes (see isPosedByAnimation) placed from the animated pose every tick with its velocity, so activation hands the solver the character's real shape and motion.

Runs on the tick, after SkeletalAnimationSystem, whose pose it reads, and before PhysicsSystem, so the solver reads these bone transforms the same step.

Member Function Documentation

init()

void Vkm::Engine::RagdollSystem::init ( FrameContext & ctx )

overridevirtual

Called once after all systems are registered, before the first update.

Parameters

ctx	The first frame's context; its products are all null.

Reimplemented from Vkm::Engine::System.

fixedUpdate()

void Vkm::Engine::RagdollSystem::fixedUpdate ( FrameContext & ctx )

overridevirtual

Execute this system at the fixed simulation rate.

Called 0+ times per frame; the step is ctx.clock.getFixedStep().

Runs before any producer stage, so ctx.visibility and ctx.ui are null here. ctx.poses is set by SkeletalAnimationSystem's own fixedUpdate, so a later Simulation system reads this tick's pose.

Parameters

ctx	This frame's services; see above for which products are set.

Reimplemented from Vkm::Engine::System.

onEntityDestroyed()

void Vkm::Engine::RagdollSystem::onEntityDestroyed ( EntityId id )

overridevirtual

Destroy a ragdoll's bones when the thing they belong to goes.

A plain destroyEntity does not walk children, and a bone moved out of the group escapes one that does; an observer catches every destroy, gameplay's included.

Parameters

id	The entity being destroyed.

Implements Vkm::Engine::ISceneObserver.
