| BodyZone | () | constructor |
public function BodyZone(body:b2Body, byMass:Boolean = true, local:Boolean = true, scale:Number)Basic constructor
Parametersbody:b2Body — The body get shapes from.
|
|
byMass:Boolean (default = true) |
|
local:Boolean (default = true) |
|
scale:Number — If true, points are considered in the bodies local co-ordinates, not world co-ordinates.
|
| contains | () | method |
public function contains(x:Number, y:Number):BooleanThe contains method determines whether a point is inside the zone.
Parametersx:Number — The x coordinate of the location to test for.
|
|
y:Number — The y coordinate of the location to test for.
|
Boolean — true if point is inside the zone, false if it is outside.
|
| getArea | () | method |
public function getArea():NumberThe getArea method returns the size of the zone. It's used by the MultiZone class to manage the balancing between the different zones.
ReturnsNumber — the size of the zone.
|
| getLocation | () | method |
public function getLocation():PointThe getLocation method returns a random point inside the zone.
ReturnsPoint — a random point inside the zone.
|
| getShapeWeights | () | method |
public function getShapeWeights():FastWeightedArrayReturns a FastWeightedArray with an entry for each shape in the body, and weightings according to mass or volume.
ReturnsFastWeightedArray |
