JointDef class

Joint definitions are used to construct joints.

class JointDef {
  JointDef() :
    type = JointType.UNKNOWN,
    userData = null,
    bodyA = null,
    bodyB = null,
    collideConnected = false { }

  /**
   * The joint type is set automatically for concrete joint types.
   */
  int type;

  /**
   * Use this to attach application specific data to your joints.
   */
  Object userData;

  /**
   * The first attached body.
   */
  Body bodyA;

  /**
   * The second attached body.
   */
  Body bodyB;

  /**
   * Set this flag to true if the attached bodies should collide.
   */
  bool collideConnected;
}

Constructors

new JointDef() #

JointDef() :
  type = JointType.UNKNOWN,
  userData = null,
  bodyA = null,
  bodyB = null,
  collideConnected = false { }

Properties

Body bodyA #

The first attached body.

Body bodyA;

Body bodyB #

The second attached body.

Body bodyB;

bool collideConnected #

Set this flag to true if the attached bodies should collide.

bool collideConnected;

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

int type #

The joint type is set automatically for concrete joint types.

int type;

Object userData #

Use this to attach application specific data to your joints.

Object userData;

Operators

bool operator ==(other) #

inherited from Object

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

bool operator ==(other) => identical(this, other);

Methods

int hashCode() #

inherited from Object

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

external int hashCode();

new JointDef() #

JointDef() :
  type = JointType.UNKNOWN,
  userData = null,
  bodyA = null,
  bodyB = null,
  collideConnected = false { }

noSuchMethod(String name, List args) #

inherited from Object

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

external Dynamic noSuchMethod(String name, List args);

const Object() #

inherited from Object

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

const Object();

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();
