Member Function Documentation

World & operator=

(

const World &

world

)

Assignment operator (deep copy)

void clear

double time

(

)

const [inline]

Get current time

void setTime

(

double

t

)

[inline]

Set current time

double timeScale

(

)

const [inline]

Get simulation speed scale

void setTimeScale

(

double

timeScale

)

[inline]

Set simulation speed scale

void addItem

(

Item *

item

)

Add new item to the world

void removeItem

(

Item *

item

)

Remove item from the world (you should delete item youself)

void deleteItem

(

Item *

item

)

[inline]

Delete item from the world (it actually deletes item)

int itemIndex

(

const Item *

item

)

const

Finds item in items()

const ItemList& items

(

)

const [inline]

Get list of all items in the World

const BodyList& bodies

(

)

const [inline]

Get list of all bodies in the World

const ForceList& forces

(

)

const [inline]

Get list of all forces in the World

Solver* solver

(

)

const [inline]

Get current solver

void setSolver

(

Solver *

solver

)

Set new solver (and delete the old one)

Solver * removeSolver

(

)

Get current solver and remove it from world

void doCalcFn

(

)

Calculate all forces

bool doEvolve

(

double

delta

)

Integrate.

Parameters:

delta

Integration interval

Returns:

true on success, false on failure (too big local error)

Todo:

Provide error message

const QString& name

(

)

const [inline, inherited]

Returns name of the object

void setName

(

const QString &

name

)

[inline, inherited]

Set name of the object
