uint	mNumPositionStepsOverride = 0
	Used only when the constraint is active. Override for the number of solver position iterations to run, 0 means use the default in PhysicsSettings::mNumPositionSteps. The number of iterations to use is the max of all contacts and constraints in the island.

Detailed Description

Rack and pinion constraint (slider & gear) settings.

Member Function Documentation

◆ Create()

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

overridevirtual

Create an instance of this constraint. Body1 should be the pinion (gear) and body 2 the rack (slider).

Implements TwoBodyConstraintSettings.

◆ RestoreBinaryState()

void RackAndPinionConstraintSettings::RestoreBinaryState ( StreamIn & inStream )

overrideprotectedvirtual

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

Reimplemented from ConstraintSettings.

◆ SaveBinaryState()

void RackAndPinionConstraintSettings::SaveBinaryState ( StreamOut & inStream ) const

overridevirtual

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

Reimplemented from ConstraintSettings.

◆ SetRatio()

void RackAndPinionConstraintSettings::SetRatio	(	int	inNumTeethRack,
		float	inRackLength,
		int	inNumTeethPinion
	)

inline

Defines the ratio between the rotation of the pinion and the translation of the rack. The ratio is defined as: PinionRotation(t) = ratio * RackTranslation(t)

Parameters

inNumTeethRack	Number of teeth that the rack has
inRackLength	Length of the rack
inNumTeethPinion	Number of teeth the pinion has

Member Data Documentation

◆ mHingeAxis

Vec3 RackAndPinionConstraintSettings::mHingeAxis = Vec3::sAxisX()

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

◆ mRatio

float RackAndPinionConstraintSettings::mRatio = 1.0f

Ratio between the rack and pinion, see SetRatio.

◆ mSliderAxis

Vec3 RackAndPinionConstraintSettings::mSliderAxis = Vec3::sAxisX()

Body 2 (rack) constraint reference frame (space determined by mSpace)

◆ mSpace

EConstraintSpace RackAndPinionConstraintSettings::mSpace = EConstraintSpace::WorldSpace

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