Detailed Description

Game objects are responsible for remembering information about themselves, in particular, their representations in Render World and Physics World.

Constructor & Destructor Documentation

CObject()

CObject::CObject	(	eSprite	t,
		b2Body *	b )

This constructor assumes that a Physics World body has already been created for this object. It then has responsibility for deleting it in its destructor.

Parameters

t	Sprite type.
b	Pointer to Physics World body.

~CObject()

CObject::~CObject

(

)

This destructor assumes that Box2D hasn't been shut down yet.

Member Function Documentation

draw()

void CObject::draw

(

)

Draw in Render World. Position and orientation must be gotten from Physics World.

Here is the call graph for this function:

EmitsStars()

const bool CObject::EmitsStars

(

)

const

Only balls that haven't rung their bell emit stars.

Returns

true if this object is still emitting stars.

GetBellRung()

const bool CObject::GetBellRung

(

)

const

Reader function for the bell rung flag.

Returns

true if the bell has rung.

GetColor()

const XMFLOAT4 & CObject::GetColor

(

)

const

Reader function for the star color.

Returns

Star color for this object.

GetPos()

const Vector2 CObject::GetPos

(

)

const

Reader function for position in Render World.

Returns

Position in Render World coordinates.

Here is the call graph for this function:

GetRingTime()

const float CObject::GetRingTime

(

)

const

Reader function for the time that the bell was rung. No check is made whether the ring time is valid. The calling function must call GetBellRung() to fund out if it is.

Returns

The time that the bell was rung.

GetSpeed()

const float CObject::GetSpeed

(

)

const

Reader function for speed in Render World.

Returns

Speed in Render World units.

Here is the call graph for this function:

GetSpriteType()

const eSprite CObject::GetSpriteType

(

)

const

Reader function for sprite type.

Returns

Sprite type.

Here is the caller graph for this function:

MakeCollide()

void CObject::MakeCollide

(

)

Make ball that has rung its bell collide with other balls after half a second delay. The delay is to make sure that they get clear of their bell first so they don't collide with incoming balls.

SetBellRung()

void CObject::SetBellRung

(

)

Set the flag indicating that this object has rung its bell and record the TOI.

Here is the caller graph for this function:
