Class Constraint

Definition

Namespace:
Tizen.NUI.Physics2D.Chipmunk
Assembly:
Tizen.NUI.Physics2D.dll

Base class of all constraints. You usually don’t want to create instances of this class directly, but instead use one of the specific constraints such as the PinJoint.

Constraint(IntPtr)

Construct a constraint with the given native handle.

Declaration
protected Constraint(System.IntPtr handle)
Parameters
Type Name Description
System.IntPtr handle

Properties

View Source

BodyA

Get the first body the constraint is attached to.

Declaration
public Body BodyA { get; }
Property Value
Type Description
Body
View Source

BodyB

Get the second body the constraint is attached to.

Declaration
public Body BodyB { get; }
Property Value
Type Description
Body
View Source

CollideBodies

Whether the two bodies connected by the constraint are allowed to collide or not.

When two bodies collide, Chipmunk ignores the collisions if this property is set to False on any constraint that connects the two bodies. Defaults to True. This can be used to create a chain that self-collides, but adjacent links in the chain do not collide.

Declaration
public bool CollideBodies { get; set; }
Property Value
Type Description
bool
View Source

Data

The user-definable data pointer for this constraint.

Declaration
public object Data { get; set; }
Property Value
Type Description
object
View Source

ErrorBias

Rate at which joint error is corrected. Defaults to pow(1.0 - 0.1, 60.0) meaning that it will correct 10% of the error every 1/60th of a second.

Declaration
public double ErrorBias { get; set; }
Property Value
Type Description
double
View Source

Handle

Native handle to constraint.

Declaration
public System.IntPtr Handle { get; }
Property Value
Type Description
System.IntPtr
View Source

Impulse

Get the last impulse applied by this constraint.

Declaration
public double Impulse { get; }
Property Value
Type Description
double
View Source

MaxBias

The maximum rate at which joint error is corrected.

Declaration
public double MaxBias { get; set; }
Property Value
Type Description
double
View Source

MaxForce

; The maximum force that this constraint is allowed to use.

Declaration
public double MaxForce { get; set; }
Property Value
Type Description
double

PostSolve

Post-solve function that is called after the solver runs.

Declaration
public Action<Constraint, Space> PostSolve { get; set; }
Property Value
Type Description
Action<, ><Constraint, Space>
View Source

PreSolve

Pre-solve function that is called before the solver runs.

Declaration
public Action<Constraint, Space> PreSolve { get; set; }
Property Value
Type Description
Action<, ><Constraint, Space>
View Source

Space

Get the cpSpace this constraint is added to.

Declaration
public Space Space { get; }
Property Value
Type Description
Space
