Detailed Description

The Transform3D is an entity component providing position and rotation for a 3D object.

Always use the factory create method Create(FPVector3) or Create(FPVector3, FPQuaternion) or correctly initialize the rotation Quaternion manually.

Member Function Documentation

◆ Create() [1/2]

static Transform3D Quantum.Transform3D.Create ( FPVector3 position = default )

inlinestatic

Factory create a Transform3D component.

Sets the Rotation to FPQuaternion.Identity.

Parameters

position The initial world position.

Returns: New initialized Transform3D component.

◆ Create() [2/2]

static Transform3D Quantum.Transform3D.Create	(	FPVector3	position,
		FPQuaternion	rotation
	)

inlinestatic

Factory create a Transform3D component.

Parameters

position	The initial world position.
rotation	The initial rotation.

Returns: New initialized Transform3D component.

◆ RotateAround()

void Quantum.Transform3D.RotateAround	(	FPVector3	point,
		FPVector3	axis,
		FP	angle,
		bool	rotateTransform = `true`
	)

inline

Rotates around a given pivot point.

The method works as expected but does generate slightly different results than Unity's Transform.RotateAround(). The algorithm may be subject to change in future versions.

Parameters

point	The pivot point.
axis	What axis to rotate.
angle	The angle.
rotateTransform

◆ Serialize()

static void Quantum.Transform3D.Serialize	(	void *	ptr,
		FrameSerializer	serializer
	)

inlinestatic

Serializes a Transform3D into a FrameSerializer.

Parameters

ptr	The pointer to the Transform3D.
serializer	The FrameSerializer instance into which the struct will be serialized.

◆ GetHashCode()

override int Quantum.Transform3D.GetHashCode ( )

inline

Overrides the hash code generation of this type.

Returns: A hash code of the current state of this instance.

◆ InverseTransformDirection()

FPVector3 Quantum.Transform3D.InverseTransformDirection ( FPVector3 direction )

Transforms a direction from world space to local space. Rotation is expected to be normalized.

◆ TransformDirection()

FPVector3 Quantum.Transform3D.TransformDirection ( FPVector3 direction )

Transforms a direction from local space to world space. Rotation is expected to be normalized.

◆ InverseTransformPoint()

FPVector3 Quantum.Transform3D.InverseTransformPoint ( FPVector3 position )

Transforms a position from world space to local space. Rotation is expected to be normalized.

◆ TransformPoint()

FPVector3 Quantum.Transform3D.TransformPoint ( FPVector3 position )

Transforms a position from local space to world space. Rotation is expected to be normalized.

◆ LookAt()

void Quantum.Transform3D.LookAt	(	FPVector3	position,
		FPVector3?	up = `null`
	)

inline

Rotates the transform so the forward vector points at position . If up is not set, will use FPVector3.Up instead.

Parameters

position
up

◆ Rotate() [1/3]

void Quantum.Transform3D.Rotate	(	FPVector3	angles,
		bool	normalize = `true`
	)

inline

Applies a rotation of angles .z degrees around the z-axis, angles .x degrees around the x-axis, and angles .y degrees around the y-axis (in that order).

Parameters

angles	Euler angles, in degrees.
normalize	If the resultant quaternion should be normalized before being set to the Rotation. This prevents rounding error from accumulating and potentially rounding the quaternion magnitude towards zero over time.

◆ Rotate() [2/3]

void Quantum.Transform3D.Rotate	(	FP	xAngle,
		FP	yAngle,
		FP	zAngle,
		bool	normalize = `true`
	)

inline

Applies a rotation of zAngle degrees around the z-axis, xAngle degrees around the x-axis, and yAngle degrees around the y-axis (in that order).

Parameters

xAngle
yAngle
zAngle
normalize	If the resultant quaternion should be normalized before being set to the Rotation. This prevents rounding error from accumulating and potentially rounding the quaternion magnitude towards zero over time.

◆ Rotate() [3/3]

void Quantum.Transform3D.Rotate	(	FPVector3	axis,
		FP	angle,
		bool	normalize = `true`
	)

inline

Rotates the object around the given axis by the number of degrees defined by the given angle.

Parameters

axis
angle
normalize	If the resultant quaternion should be normalized before being set to the Rotation. This prevents rounding error from accumulating and potentially rounding the quaternion magnitude towards zero over time.
