Member Function Documentation

◆ Create()

TwoBodyConstraint * GearConstraintSettings::Create	(	Body &	inBody1,
		Body &	inBody2
	)		const

overridevirtual

Create an instance of this constraint.

Implements TwoBodyConstraintSettings.

◆ RestoreBinaryState()

void GearConstraintSettings::RestoreBinaryState ( StreamIn & inStream )

overrideprotectedvirtual

This function should not be called directly, it is used by sRestoreFromBinaryState.

Reimplemented from ConstraintSettings.

◆ SaveBinaryState()

void GearConstraintSettings::SaveBinaryState ( StreamOut & inStream ) const

overridevirtual

Saves the contents of the constraint settings in binary form to inStream.

Reimplemented from ConstraintSettings.

◆ SetRatio()

void GearConstraintSettings::SetRatio	(	int	inNumTeethGear1,
		int	inNumTeethGear2
	)

inline

Defines the ratio between the rotation of both gears The ratio is defined as: Gear1Rotation(t) = -ratio * Gear2Rotation(t)

Parameters

inNumTeethGear1	Number of teeth that body 1 has
inNumTeethGear2	Number of teeth that body 2 has

Member Data Documentation

◆ mHingeAxis1

Vec3 GearConstraintSettings::mHingeAxis1 = Vec3::sAxisX()

Body 1 constraint reference frame (space determined by mSpace).

◆ mHingeAxis2

Vec3 GearConstraintSettings::mHingeAxis2 = Vec3::sAxisX()

Body 2 constraint reference frame (space determined by mSpace)

◆ mRatio

float GearConstraintSettings::mRatio = 1.0f

Ratio between both gears, see SetRatio.

◆ mSpace

EConstraintSpace GearConstraintSettings::mSpace = EConstraintSpace::WorldSpace

This determines in which space the constraint is setup, all properties below should be in the specified space.
