Libraries.Game.Physics.Joints.ConeTwistJoint3D Documentation

This is a joint that describes how much freedom can one object rotate about another object. This joint is different than the ball and socket joint in that there is an angular limit to how much the rotating object can rotate.

Actions Documentation

BuildJacobian()

This action is called by the Collision Solver to gather information on the joint before calling the SolveJoint action. This action is used internally.

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

GetAppliedImpulse()

This action returns the amount of impulse that should be applied to the items in the joints to allow them to continue to be joined.

Return

number: the amount of impulse that should be applied to the items.

GetEdgeA()

This action returns the first JointEdge3D stored inside this Joint3D.

Return

Libraries.Game.Physics.Joints.JointEdge3D: the first JointEdge3D stored inside this Joint3D.

GetEdgeB()

This action returns the second JointEdge3D stored inside this Joint3D.

Return

Libraries.Game.Physics.Joints.JointEdge3D: the second JointEdge3D stored inside this Joint3D.

GetHashCode()

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Return

integer: The integer hash code of the object.

GetInformation(Libraries.Game.Physics.CollisionSolverInformation3D information)

Parameters

GetItemA()

This action returns the first 3D item that is joined by this Joint3D.

Return

Libraries.Interface.Item3D: the first 3D item that is joined by this Joint3D.

GetItemB()

This action returns the second 3D item that is joined by this Joint3D.

Return

Libraries.Interface.Item3D: the second 3D item that is joined by this Joint3D.

GetNext()

This action gets you the next information about a joint (stored in another Joint3D) inside a linked list of Joint3Ds.

Return

Libraries.Game.Physics.Joints.Joint3D: the next joint.

GetPrevious()

This action gets you the previous information about a joint (stored in another Joint3D) inside a linked list of Joint3Ds.

Return

Libraries.Game.Physics.Joints.Joint3D: the previous joint.

GetType()

This action returns the type of joint that you have.

Return

integer: the type of joint that you have.

InCollisionGroup()

This action returns whether this joint is been accounted for in a collision group.

Return

boolean: true when the joint has already been assigned to a collision group, false if the joint is not
