Properties

int pointCount;
List<ContactConstraintPoint> points #

final Type runtimeType #

int type;
Operators
bool operator ==(other) #
The equality operator.
The default behavior for all Object
s 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
new ContactConstraint() #
ContactConstraint() : points = new List<ContactConstraintPoint>(Settings.MAX_MANIFOLD_POINTS), pointCount = 0, manifold = null, localNormal = new Vector(), localPoint = new Vector(), normal = new Vector(), normalMass = new Matrix22(), K = new Matrix22() { for (int i = 0; i < Settings.MAX_MANIFOLD_POINTS; i++) { points[i] = new ContactConstraintPoint(); } }
int hashCode() #
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();
noSuchMethod(String name, List args) #
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() #
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();
void setFrom(ContactConstraint cp) #
void setFrom(ContactConstraint cp) { pointCount = cp.pointCount; localNormal.setFrom(cp.localNormal); localPoint.setFrom(cp.localPoint); normal.setFrom(cp.normal); normalMass.setFrom(cp.normalMass); K.setFrom(cp.K); bodyA = cp.bodyA; bodyB = cp.bodyB; type = cp.type; radius = cp.radius; friction = cp.friction; restitution = cp.restitution; manifold = cp.manifold; for(int i=0; i<cp.pointCount; i++) { points[i].setFrom(cp.points[i]); } }
String toString() #
Returns a string representation of this object.
String toString() { String result = 'localNormal: "$localNormal", localPoint: "$localPoint" ' 'normal: "$normal", radius: "$radius" friction: "$friction" ' 'restitution: "$restitution", pointCount: "$pointCount"'; return result; }
