Actions Documentation

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)

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)

GetAnchorA()

This action sets whether this joint is INACTIVE, AT_LOWER, AT_UPPER, or EQUAL.

Return

Libraries.Compute.Vector2:

GetAnchorB()

This action returns whether this joint is INACTIVE, AT_LOWER, AT_UPPER, or EQUAL.

Return

Libraries.Compute.Vector2: the state of the joint.

GetCollideConnected()

This action returns whether the connected joints can collide or not.

Return

boolean: whether the connected joints can collide or not.

GetEdgeA()

This action returns the first JointEdge2D stored inside this Joint2D.

Return

Libraries.Game.Physics.Joints.JointEdge2D: the first JointEdge2D stored inside this Joint2D.

GetEdgeB()

This action returns the second JointEdge2D stored inside this Joint2D.

Return

Libraries.Game.Physics.Joints.JointEdge2D: the second JointEdge2D stored inside this Joint2D.

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()

GetItemA()

This action returns the first 2D item that is joined by this Joint2D.

Return

Libraries.Interface.Item2D: the first 2D item that is joined by this Joint2D.

GetItemB()

This action returns the second 2D item that is joined by this Joint2D.

Return

Libraries.Interface.Item2D: the second 2D item that is joined by this Joint2D.

GetNext()

This action gets you the next information about a joint (stored in another Joint2D) inside a linked list of Joint2Ds.

Return

Libraries.Game.Physics.Joints.Joint2D: the next joint.

GetPrevious()

This action gets you the previous information about a joint (stored in another Joint2D) inside a linked list of Joint2Ds.

Return

Libraries.Game.Physics.Joints.Joint2D: the previous joint.

GetReactionForce(number inverseTimeStep)

This action sets the second 2D item that is joined by this Joint2D.

Parameters

  • number inverseTimeStep

Return

Libraries.Compute.Vector2:

GetReactionTorque(number inverseTimeStep)

This action returns the second 2D item that is joined by this Joint2D.

Parameters

  • number inverseTimeStep

Return

number: the second 2D item that is joined by this Joint2D.

GetState()

This action returns whether this joint is INACTIVE, AT_LOWER, AT_UPPER, or EQUAL.

Return

integer: the state of the 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 the items in this joint is in a collision group with other items.

Return

boolean: true if the items in this joint is in a collision group with other items.
