Libraries.Game.Physics.Mass2D

Mass2D is a class representing a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D
use Libraries.Compute.Vector2

Vector2 vectorSetting
vectorSetting:Set(8.0, 9.0)
Mass2D mass
mass:SetMass(5.0)
mass:SetInertia(2.0)
mass:SetCenter(vectorSetting)

number newMass = mass:GetMass()
number newInertia = mass:GetInertia()
number newX = mass:GetCenter():GetX()
number newY = mass:GetCenter():GetY()
output "The new mass has a mass of " + newMass + ", inertia of: " + newInertia + ", x center at: " + newX + ", and y center at: " + newY

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 returns a copy of the current mass. The copied mass will have the same mass, center, and inertia as the current mass.

Example Code

use Libraries.Game.Physics.Mass2D
    use Libraries.Compute.Vector2

    Vector2 vectorSetting
    vectorSetting:Set(8.0, 9.0)
    Mass2D massBeingCopied

    //setting the mass that we will copy
    massBeingCopied:SetMass(5.0)
    massBeingCopied:SetInertia(2.0)
    massBeingCopied:SetCenter(vectorSetting)


    //copy the mass
    Mass2D copyMass
    copyMass = massBeingCopied:Copy()
    number copiedMass = copyMass:GetMass()
    number copiedInertia = copyMass:GetInertia()
    number copiedX = copyMass:GetCenter():GetX()
    number copiedY = copyMass:GetCenter():GetY()
    output "The copy of the mass has a mass of " + copiedMass + ", inertia of: " + copiedInertia + ", x center at: " + copiedX + ", and y center at: " + copiedY

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 gets the vector that points to the center of the mass in 2D.

Example Code

use Libraries.Game.Physics.Mass2D
    use Libraries.Compute.Vector2

    Vector2 centerOfMassSetting
    centerOfMassSetting:Set(1.0, 3.0)

    Mass2D mass
    mass:SetCenter(centerOfMassSetting)

    Vector2 centerOfMass
    centerOfMass = mass:GetCenter()

    number xComponent = centerOfMass:GetX()
    number yComponent = centerOfMass:GetY()
    output "The center of mass vector is: <" + xComponent + ", " + yComponent + ">"

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action sets the inertia of a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D

    number inertiaSetting = 5.0
    Mass2D mass
    mass:SetInertia(inertiaSetting)

    number inertiaValue = mass:GetInertia()
    output "The inertia of mass in 2D is: " + inertiaValue

This action returns the mass of a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D

    Mass2D mass
    mass:SetMass(0.5)

    number massValue = mass:GetMass()
    output "The mass that you have set is: " + massValue

This action sets the properties of a 2D mass using another 2D mass.

Example Code

use Libraries.Game.Physics.Mass2D
    use Libraries.Compute.Vector2

    Vector2 vectorSetting
    vectorSetting:Set(8.0, 9.0)
    Mass2D mass1
    Mass2D mass2
    mass1:SetMass(5.0)
    mass1:SetInertia(2.0)
    mass1:SetCenter(vectorSetting)

    mass2:Set(mass1)
    number newMass = mass2:GetMass()
    number newInertia = mass2:GetInertia()
    number newX = mass2:GetCenter():GetX()
    number newY = mass2:GetCenter():GetY()
    output "The new mass has a mass of " + newMass + ", inertia of: " + newInertia + ", x center at: " + newX + ", and y center at: " + newY

This action sets the vector that points to the center of a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D
    use Libraries.Compute.Vector2

    Vector2 centerOfMassSetting
    centerOfMassSetting:Set(1.0, 3.0)

    Mass2D mass
    mass:SetCenter(centerOfMassSetting)

    Vector2 centerOfMass
    centerOfMass = mass:GetCenter()

    number xComponent = centerOfMass:GetX()
    number yComponent = centerOfMass:GetY()
    output "The center of mass vector is: <" + xComponent + ", " + yComponent + ">"

This action sets the inertia of a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D

    number inertiaSetting = 5.0
    Mass2D mass
    mass:SetInertia(inertiaSetting)

    number inertiaValue = mass:GetInertia()
    output "The inertia of mass in 2D is: " + inertiaValue

This action sets the value of mass of a mass in 2D space.

Example Code

use Libraries.Game.Physics.Mass2D

    Mass2D mass
    mass:SetMass(5.5)

    number massValue = mass:GetMass()
    output "The mass of this mass in 2D is: " + massValue
