SyntaxThe PointOnLineConstraint type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PointOnLineConstraint |
Initializes a new instance of the PointOnLineConstraint class.
|
Methods| Name | Description | |
|---|---|---|
| ApplyImpulse |
Called by the simulation to apply an impulse that satisfies the constraint.
(Inherited from Constraint.) |
| Equals | (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnAddToSimulation |
Called when this constraint is added to a simulation.
(Overrides ConstraintOnAddToSimulation.) |
| OnApplyImpulse |
Called when the constraint impulse should be applied.
(Overrides ConstraintOnApplyImpulse.) |
| OnChanged |
Called when properties of this constraint were changed.
(Overrides ConstraintOnChanged.) |
| OnRemoveFromSimulation |
Called when this constraint is removed from a simulation.
(Overrides ConstraintOnRemoveFromSimulation.) |
| OnSetup |
Called when constraint should be set-up for a new time step.
(Overrides ConstraintOnSetup.) |
| Setup |
Called by the simulation to prepare this constraint for constraint solving for a new time
step.
(Inherited from Constraint.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties| Name | Description | |
|---|---|---|
 | AnchorPositionALocal | |
| AnchorPositionBLocal | |
| AngularConstraintImpulse |
Gets or sets the angular constraint impulse that was applied.
(Overrides ConstraintAngularConstraintImpulse.) |
| AxisALocal | |
| BodyA |
Gets or sets the first body.
(Inherited from Constraint.) |
| BodyB |
Gets or sets the second body.
(Inherited from Constraint.) |
| CollisionEnabled | (Inherited from Constraint.) |
| Enabled |
Gets or sets a value indicating whether this constraint is enabled.
(Inherited from Constraint.) |
| ErrorReduction |
Gets or sets the error reduction parameter.
|
| LinearConstraintImpulse |
Gets or sets the linear constraint impulse that was applied.
(Overrides ConstraintLinearConstraintImpulse.) |
| MaxForce |
Gets or sets the maximal force that is applied by this constraint.
|
| Maximum |
Gets or sets the maximum movement limit on the line.
|
| Minimum |
Gets or sets the minimum movement limit on the line.
|
| RelativePosition |
Gets the position on the line axis relative to AnchorPositionALocal.
|
| Restitution |
Gets or sets the coefficient of restitution for limits.
|
| Simulation |
Gets the simulation to which this constraint belongs.
(Inherited from Constraint.) |
| Softness |
Gets or sets the softness.
|
Remarks
A line axis is fixed on BodyA. The line goes through the point
AnchorPositionALocal on the first body and the direction of the line is defined
by AxisALocal. AnchorPositionBLocal on
BodyB is constrained to be on the line on the first body. This joint
removes 2 translational degrees of movement (only relative movement on the line is allowed).
It does not restrict rotational movement.
