Libraries.Game.Collision.Shapes.Box Documentation

This class describes the box shape in 3D.

Inherits from: Libraries.Language.Object, Libraries.Game.Collision.Shapes.CollisionShape3D

Actions Documentation

CalculateLocalInertia(number mass, Libraries.Compute.Vector3 inertia)

This action approximates the mass moment of inertia of a box relative to that box's local origin.

Parameters

CalculateTemporalBoundingBox(Libraries.Game.Collision.PhysicsPosition3D currentTransform, Libraries.Compute.Vector3 linearVelocity, Libraries.Compute.Vector3 angularVelocity, number timeStep, Libraries.Game.BoundingBox temporalBoundingBox)

This action calculates the rectangular cube that will contain both the object in its position currently and also contain the object in a position after "timeStep" seconds from now.

Parameters

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.

Parameters

Return

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

Example

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

ComputeBoundingBox(Libraries.Game.BoundingBox boundingBox, Libraries.Game.Collision.PhysicsPosition3D transform)

This action finds the bounding box that would bound the Box in its current position.

Parameters

Copy()

This action sets another box to have the properties of the current box.

Return

Libraries.Game.Collision.Shapes.CollisionShape3D:

Equals(Libraries.Language.Object object)

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

Parameters

Return

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

Example

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

GetAngularMotionDisc()

This calculates the maximum distance between any point to the center of the 3D object.

Return

number:

GetBoundingSphere(Libraries.Compute.Vector3 center)

This action finds the center (relative to the object's local origin) and the radius of a sphere that would bound the object that is at its current position.

Parameters

Return

number:

GetChildCount()

This action returns how many children shapes are attached to this box.

Return

integer:

GetEdge(integer i, Libraries.Compute.Vector3 pa, Libraries.Compute.Vector3 pb)

This action calculates the vertices that makes up one of the edges of this box.

Parameters

GetHalfExtentsWithMargin()

This action returns a vector that records information about the box's width, height, and depth with an offset.

Return

Libraries.Compute.Vector3:

GetHalfExtentsWithoutMargin()

This action returns a vector that records information about the box's width, height, and depth without an offset.

Return

Libraries.Compute.Vector3:

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

GetLocalScaling(Libraries.Compute.Vector3 out)

This action returns how the 3D object has been scaled to the shape that it has right now.

Parameters

Return

Libraries.Compute.Vector3:

GetMargin()

This action returns the offset of the box that will bound the object to prevent objects going through each other graphically.

Return

number:

GetNumberOfEdges()

This action returns 12 for 12 edges that makes up a box.

Return

integer:

GetNumberOfPlanes()

This action returns 6 for 6 planes that makes up a box.

Return

integer:

GetNumberOfVertices()

This action returns 8 for 8 vertices that makes up a box.

Return

integer:

GetNumberPreferredPenetrationDirections()

This action calculates the preferred number of directions to check if another object has penetrated this box.

Return

integer:

GetPlane(Libraries.Compute.Vector3 planeNormal, Libraries.Compute.Vector3 planeSupport, integer i)

This action returns one of the 6 planes that made up the bounding box for this box.

Parameters

GetPlaneEquation(Libraries.Compute.Plane plane, integer i)

This action calculates the equation of one of the planes that makes up a box.

Parameters

GetPreferredPenetrationDirection(integer index, Libraries.Compute.Vector3 penetrationVector)

This action calculates one of the directions to check if another object has penetrated this box.

Parameters

GetType()

This action returns what type of 3D object the 3D object is.

Return

integer:

GetVertex(integer i, Libraries.Compute.Vector3 vertex)

This action returns the ith vertex of this box.

Parameters

IsInside(Libraries.Compute.Vector3 point, number tolerance)

This action calculates if a point is inside the box.

Parameters

Return

boolean:

LocalGetSupportingVertex(Libraries.Compute.Vector3 vector)

This action finds the vertex with an offset (margin) of the 3D shape that is furthest away in a direction specified by "Vector3 vector".

Parameters

Return

Libraries.Compute.Vector3:

LocalGetSupportingVertexWithoutMargin(Libraries.Compute.Vector3 vector)

This action finds the vertex with an offset (margin) of the 3D shape that is furthest away in a direction specified by "Vector3 vector" without an offset.

Parameters

Return

Libraries.Compute.Vector3:

Scale(Libraries.Compute.Vector3 scale)

This action scales the Box from its current size.

Parameters

Set(number width, number height, number depth)

This action sets the properties of this box using passed in sizes.

Parameters

  • number width
  • number height
  • number depth

SetLocalScaling(Libraries.Compute.Vector3 scaling)

This action scales the size of the Box from its original size.

Parameters

SetMargin(number margin)

This action sets the offset of the box that will bound the object to prevent objects going through each other graphically.

Parameters

  • number margin

SetType(integer type)

This action sets what type of 3D object this 3D object is.

Parameters

  • integer type
