Libraries.Game.Physics.ConstraintDescription3D

This class stores different constraint values that allows us to describe a joint constraint.

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)

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)

This action returns a number whose reciprocal will be used to scale the impulse change applied to linear velocity.

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action initializes this ConstraintDescription3D such that this class is used to store one constraitn on one rigid body. action Initialize(Matrix3 world2A, Vector3 relativePosition1, Vector3 relativePosition2, Vector3 jointAxis, Vector3 inertiaInverseA, number massInverseA) linearJointAxis:Set(jointAxis) aJ:Set(relativePosition1):CrossProduct(jointAxis) world2A:Transform(aJ) bJ:Set(jointAxis) bJ:Scale(-1) Vector3 temp temp:Set(relativePosition2):CrossProduct(bJ) bJ:Set(temp) world2A:Transform(bJ) minvJt0:SetX(inertiaInverseA:GetX() * aJ:GetX()) minvJt0:SetY(inertiaInverseA:GetY() * aJ:GetY()) minvJt0:SetZ(inertiaInverseA:GetZ() * aJ:GetZ()) minvJt1:Set(0, 0, 0) diag = massInverseA + minvJt0:DotProduct(aJ) end

This action returns a number whose reciprocal will be used to scale the impulse change applied to angular velocity if this ConstraintDescription3D describes 2 constraints shared by two different rigid bodies.

This action returns a number whose reciprocal will be used to scale the impulse change applied to angular velocity if this ConstraintDescription3D describes 2 constraints on the same rigid body.

This action returns the relative velocities between two 3D objects whose constraints are stored inside this ConstraintDescription3D.

This action initializes this ConstraintDescription3D such that this class is used to store the angular constraint between two rigid bodies.

This action initializes this ConstraintDescription3D such that this class is used to store the angular constraint between two rigid bodies.

relativePosition1: relative position of constraint coordinate system center in world coordinates relativePosition2: relative position of constraint coordinate system center in world coordinates This action intializeds the description such that this ConstraintDescription3D is used for the constraint between two different rigid bodies.
