Detailed Description

Runtime character object. This object usually represents the player or a humanoid AI. It uses a single rigid body, usually with a capsule shape to simulate movement and collision for the character. The character is a keyframed object, the application controls it by setting the velocity.

Constructor & Destructor Documentation

◆ Character()

Character::Character	(	const CharacterSettings *	inSettings,
		RVec3Arg	inPosition,
		QuatArg	inRotation,
		uint64	inUserData,
		PhysicsSystem *	inSystem
	)

Constructor

Parameters

inSettings	The settings for the character
inPosition	Initial position for the character
inRotation	Initial rotation for the character (usually only around Y)
inUserData	Application specific value
inSystem	Physics system that this character will be added to later

◆ ~Character()

Character::~Character ( )

overridevirtual

Destructor.

Member Function Documentation

◆ Activate()

void Character::Activate ( bool inLockBodies = true )

Wake up the character.

◆ AddImpulse()

void Character::AddImpulse	(	Vec3Arg	inImpulse,
		bool	inLockBodies = `true`
	)

Add impulse to the center of mass of the character.

◆ AddLinearVelocity()

void Character::AddLinearVelocity	(	Vec3Arg	inLinearVelocity,
		bool	inLockBodies = `true`
	)

Add world space linear velocity to current velocity (m / s)

◆ AddToPhysicsSystem()

void Character::AddToPhysicsSystem	(	EActivation	inActivationMode = `EActivation::Activate`,
		bool	inLockBodies = `true`
	)

Add bodies and constraints to the system and optionally activate the bodies.

◆ CheckCollision()

void Character::CheckCollision	(	RVec3Arg	inPosition,
		QuatArg	inRotation,
		Vec3Arg	inMovementDirection,
		float	inMaxSeparationDistance,
		const Shape *	inShape,
		RVec3Arg	inBaseOffset,
		CollideShapeCollector &	ioCollector,
		bool	inLockBodies = `true`
	)		const

Get all contacts for the character at a particular location.

Parameters

inPosition	Position to test.
inRotation	Rotation at which to test the shape.
inMovementDirection	A hint in which direction the character is moving, will be used to calculate a proper normal.
inMaxSeparationDistance	How much distance around the character you want to report contacts in (can be 0 to match the character exactly).
inShape	Shape to test collision with.
inBaseOffset	All hit results will be returned relative to this offset, can be zero to get results in world position, but when you're testing far from the origin you get better precision by picking a position that's closer e.g. GetPosition() since floats are most accurate near the origin
ioCollector	Collision collector that receives the collision results.
inLockBodies	If the collision query should use the locking body interface (true) or the non locking body interface (false)

inline

Remove bodies and constraints from the system.

◆ SetLayer()

◆ SetShape()

bool Character::SetShape	(	const Shape *	inShape,
		float	inMaxPenetrationDepth,
		bool	inLockBodies = `true`
	)

Switch the shape of the character (e.g. for stance). When inMaxPenetrationDepth is not FLT_MAX, it checks if the new shape collides before switching shape. Returns true if the switch succeeded.
