Detailed Description

A system of interlocking gears.

The number and positions of the gears are hard-coded but there is enough storage for any number of them.

Constructor & Destructor Documentation

CGear()

CGear::CGear	(	float	x,
		float	y
	)

Constructor.

Parameters

x	X coordinate in Physics World units.
y	Y coordinate in Physics World units.

Member Function Documentation

CreateBase()

b2Body * CGear::CreateBase ( float  x, float  y  )

private

Create invisible base in Physics World.

Create an invisible base to attach the largest gear wheel to. The base has no sprite and no shape in Physics World. The latter means it doesn't collide with anything.

Parameters

x	X coordinate in Physics World units.
y	Y coordinate in Physics World units.

Returns

Pointer to the cog wheel body in Physics World.

CreateGear()

b2Body * CGear::CreateGear ( float  x, float  y, eSprite  t  )

private

Create gear wheel in Physics World.

Create a gear wheel at a given position in Physics World.

Parameters

x	X coordinate in Physics World units.
y	Y coordinate in Physics World units.
t	Sprite type of the gear wheel.

Returns

Pointer to the cog wheel body in Physics World.

CreateGearJoint()

void CGear::CreateGearJoint ( UINT  i, UINT  j, float  r  )

private

Create gear joint in Physics World.

Create a gear joint between two of hthe revolute joints in m_pJoint.

Parameters

i	Index of first revolute joint and body attached to it.
j	Index of second revolute joint and body attached to it.
r	Gear ratio.

CreateRoundGears()

void CGear::CreateRoundGears ( float  x, float  y  )

private

Create round gears in Physics World.

Create the square gears and push them onto the gear list. It is assumed that this function is called first and that the driving gear (the one with the motor on its revolute joint) is to be the first one on the gear list.

Parameters

x	X coordinate in Physics World units.
y	Y coordinate in Physics World units.

CreateSquareGears()

void CGear::CreateSquareGears ( float  x, float  y  )

private

Create square gears in Physics World.

Create the square gears and push them onto the gear list.

Parameters

x	X coordinate in Physics World units.
y	Y coordinate in Physics World units.

reverse()

void CGear::reverse

(

)

Reverse gears.

Reverse the gears by setting the motor speed on the revolute joint for the first gear.
