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.

Example Code

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

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(

Parameters

Return

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

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.

GetNormal()

This action returns the normal vector of this collision.

Return

Libraries.Compute.Vector2: the normal vector of this collisio

GetPoint()

This action returns the clipping point of this collision.

Return

Libraries.Compute.Vector2: the clipping point of this collisio

GetSeparation()

This action returns the minimum distance between the two objects colliding.

Return

number: the minimum distance between the two objects collidin

Initialize(Libraries.Game.Physics.CollisionPositionConstraint pc, Libraries.Game.Collision.PhysicsPosition2D xfA, Libraries.Game.Collision.PhysicsPosition2D xfB, integer index)

This action initializes the variables stored inside this class.
