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 will return an integer mask based on the contained VertexAttribute objects. The integer mask is calculated by using bitwise Or operations on the usage value of each VertexAttribute.

Parameters

Return

boolean:

FindByUsage(integer usage)

Parameters

  • integer usage

Return

Libraries.Game.Graphics.VertexAttribute

GetAttribute(integer index)

Parameters

  • integer index

Return

Libraries.Game.Graphics.VertexAttribute

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()

GetIterator()

Return

Libraries.Containers.Iterator

GetMask()

This action will return an integer mask based on the contained VertexAttribute objects. The integer mask is calculated by using bitwise Or operations on the usage value of each VertexAttribute.

Return

integer:

GetOffset(integer usage)

Parameters

  • integer usage

Return

integer

GetSize()

Return

integer

HasAttribute(integer attributeCode)

This action tests if a particular type of VertexAttribute (as identified by its integer code) is present in the VertexAttributes. Most commonly, the code should be one of the constants in this class, such as POSITION or NORMAL.

Parameters

  • integer attributeCode: An integer representing a VertexAttribute, such as the POSITION constant in this class

Return

boolean:

SetAttributes(Libraries.Containers.Array<Libraries.Game.Graphics.VertexAttribute> array)

Parameters
