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
inNumTeethRackNumber of teeth that the rack has
inRackLengthLength of the rack
inNumTeethPinionNumber 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.
