/ * *
* A ` Number ` that _measures_ the current angular velocity of the body after the last ` Body.update ` . It is read - only .
* If you need to modify a body 's angular velocity directly, you should apply a torque or simply change the body' s ` angle ` ( as the engine uses position - Verlet integration ) .

/ * *
* A ` Number ` that defines the density of the body , that is its mass per unit area .
* If you pass the density via ` Body.create ` the ` mass ` property is automatically calculated for you based on the size ( area ) of the object .
* This is generally preferable to simply setting mass and allows for more intuitive definition of materials ( e . g . rock has a higher density than wood ) .

* A value of ` 1 ` means the body may come to a stop almost instantly after a force is applied .
*
* The effects of the value may be non - linear .
* High values may be unstable depending on the body .
* The engine uses a Coulomb friction model including static and kinetic friction .

* @type number
* @default 0.01
* /
frictionAir? : number ;
/ * *
* A ` Number ` that defines the moment of inertia ( i . e . second moment of area ) of the body .
* It is automatically calculated from the given convex hull ( ` vertices ` array ) and density in ` Body.create ` .
* If you modify this value , you must also modify the ` body.inverseInertia ` property ( ` 1 / inertia ` ) .

*
* @property isSensor
* @type boolean
* @default false
* /
isSensor? : boolean ;
/ * *
* A flag that indicates whether the body is considered sleeping . A sleeping body acts similar to a static body , except it is only temporary and can be awoken .
* If you need to set a body as sleeping , you should use ` Sleeping.set ` as this requires more than just setting this flag .
*
* @property isSleeping
* @type boolean
* @default false
* /
isSleeping? : boolean ;
/ * *
* A flag that indicates whether a body is considered static . A static body can never change position or angle and is completely fixed .
* If you need to set a body as static after its creation , you should use ` Body.setStatic ` as this requires more than just setting this flag .

*
* @property mass
* @type number
* /
mass? : number ;
/ * *
* A ` Number ` that _measures_ the amount of movement a body currently has ( a combination of ` speed ` and ` angularSpeed ` ) . It is read - only and always positive .

*
* @property render
* @type object
* /
render? : IBodyRenderOptions ;
/ * *
* A ` Number ` that defines the restitution ( elasticity ) of the body . The value is always positive and is in the range ` (0, 1) ` .
* A value of ` 0 ` means collisions may be perfectly inelastic and no bouncing may occur .
* A value of ` 0.8 ` means the body may bounce back with approximately 80 % of its kinetic energy .
* Note that collision response is based on _pairs_ of bodies , and that ` restitution ` values are _combined_ with the following formula :
*
* Math . max ( bodyA . restitution , bodyB . restitution )
*
* @property restitution
* @type number
* @default 0
* /
restitution? : number ;
/ * *
* A ` Number ` that defines the number of updates in which this body must have near - zero velocity before it is set as sleeping by the ` Matter.Sleeping ` module ( if sleeping is enabled by the engine ) .

* @property sleepThreshold
* @type number
* @default 60
* /
sleepThreshold? : number ;
/ * *
* A ` Number ` that specifies a tolerance on how far a body is allowed to 'sink' or rotate into other bodies .
* Avoid changing this value unless you understand the purpose of ` slop ` in physics engines .
* The default should generally suffice , although very large bodies may require larger values for stable stacking .
*
* @property slop
* @type number
* @default 0.05
* /
slop? : number ;
/ * *
* A ` Number ` that _measures_ the current speed of the body after the last ` Body.update ` . It is read - only and always positive ( it ' s the magnitude of ` body.velocity ` ) .
*
* @readOnly
* @property speed
* @type number
* @default 0
* /
speed? : number ;
/ * *
* A ` Number ` that allows per - body time scaling , e . g . a force - field where bodies inside are in slow - motion , while others are at full speed .
*
* @property timeScale
* @type number
* @default 1
* /
timeScale? : number ;
/ * *
* A ` Number ` that specifies the torque ( turning force ) to apply in the current step . It is zeroed after every ` Body.update ` .
*
* @property torque

/ * *
* A ` String ` denoting the type of object .
*
* @property type
* @type string
* @default "body"
* /
type ? : string ;
/ * *
* A ` Vector ` that _measures_ the current velocity of the body after the last ` Body.update ` . It is read - only .
* If you need to modify a body 's velocity directly, you should either apply a force or simply change the body' s ` position ` ( as the engine uses position - Verlet integration ) .
*
* @readOnly
* @property velocity
* @type vector
* @default { x : 0 , y : 0 }
* /
velocity? : Vector ;
/ * *
* An array of ` Vector ` objects that specify the convex hull of the rigid body .
* These should be provided about the origin ` (0, 0) ` . E . g .
*
* [ { x : 0 , y : 0 } , { x : 25 , y : 50 } , { x : 50 , y : 0 } ]
*
* When passed via ` Body.create ` , the vertices are translated relative to ` body.position ` ( i . e . world - space , and constantly updated by ` Body.update ` during simulation ) .
* The ` Vector ` objects are also augmented with additional properties required for efficient collision detection .
*
* Other properties such as ` inertia ` and ` bounds ` are automatically calculated from the passed vertices ( unless provided via ` options ` ) .
* Concave hulls are not currently supported . The module ` Matter.Vertices ` contains useful methods for working with vertices .
*
* @property vertices
* @type vector [ ]
* /
vertices? : Array < Vector > ;
/ * *
* An array of bodies that make up this body .
* The first body in the array must always be a self reference to the current body instance .
* All bodies in the ` parts ` array together form a single rigid compound body .
* Parts are allowed to overlap , have gaps or holes or even form concave bodies .
* Parts themselves should never be added to a ` World ` , only the parent body should be .
* Use ` Body.setParts ` when setting parts to ensure correct updates of all properties .
*

*
* @property parent
* @type body
* /
parent? : BodyType ;
/ * *
* A ` Number ` that defines the static friction of the body ( in the Coulomb friction model ) .
* A value of ` 0 ` means the body will never 'stick' when it is nearly stationary and only dynamic ` friction ` is used .
* The higher the value ( e . g . ` 10 ` ) , the more force it will take to initially get the body moving when nearly stationary .
* This value is multiplied with the ` friction ` property to make it easier to change ` friction ` and maintain an appropriate amount of static friction .
*
* @property frictionStatic
* @type number
* @default 0.5
* /
frictionStatic? : number ;
/ * *
* An ` Object ` that specifies the collision filtering properties of this body .
*
* Collisions between two bodies will obey the following rules :
* - If the two bodies have the same non - zero value of ` collisionFilter.group ` ,
* they will always collide if the value is positive , and they will never collide
* if the value is negative .
* - If the two bodies have different values of ` collisionFilter.group ` or if one
* ( or both ) of the bodies has a value of 0 , then the category / mask rules apply as follows :
*
* Each body belongs to a collision category , given by ` collisionFilter.category ` . This
* value is used as a bit field and the category should have only one bit set , meaning that
* the value of this property is a power of two in the range [ 1 , 2 ^ 31 ] . Thus , there are 32
* different collision categories available .
*
* Each body also defines a collision bitmask , given by ` collisionFilter.mask ` which specifies
* the categories it collides with ( the value is the bitwise AND value of all these categories ) .
*
* Using the category / mask rules , two bodies ` A ` and ` B ` collide if each includes the other ' s
* category in its mask , i . e . ` (categoryA & maskB) !== 0 ` and ` (categoryB & maskA) !== 0 `
* are both true .

* they will always collide if the value is positive , and they will never collide
* if the value is negative .
* - If the two bodies have different values of ` collisionFilter.group ` or if one
* ( or both ) of the bodies has a value of 0 , then the category / mask rules apply as follows :
*
* Each body belongs to a collision category , given by ` collisionFilter.category ` . This
* value is used as a bit field and the category should have only one bit set , meaning that
* the value of this property is a power of two in the range [ 1 , 2 ^ 31 ] . Thus , there are 32
* different collision categories available .
*
* Each body also defines a collision bitmask , given by ` collisionFilter.mask ` which specifies
* the categories it collides with ( the value is the bitwise AND value of all these categories ) .
*
* Using the category / mask rules , two bodies ` A ` and ` B ` collide if each includes the other ' s
* category in its mask , i . e . ` (categoryA & maskB) !== 0 ` and ` (categoryB & maskA) !== 0 `

* The ` Matter.World ` module contains methods for creating and manipulating the world composite .
* A ` Matter.World ` is a ` Matter.Composite ` body , which is a collection of ` Matter.Body ` , ` Matter.Constraint ` and other ` Matter.Composite ` .
* A ` Matter.World ` has a few additional properties including ` gravity ` and ` bounds ` .
* It is important to use the functions in the ` Matter.Composite ` module to modify the world composite , rather than directly modifying its properties .
* There are also a few methods here that alias those in ` Matter.Composite ` for easier readability .
*
* See the included usage [ examples ] ( https : //github.com/liabru/matter-js/tree/master/examples).
