Libraries.Game.Collision.CollisionIdentifier2D Documentation

This class identifies the two objects' shapes that are involved in a collision and what type of collision is involved (vertex with vertex collision, vertex with face collision, face with face collision). This class is used internally by BroadphaseCollision2D and by CollisionPoint2

Inherits from: Libraries.Language.Object

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.Game.Collision.CollisionIdentifier2D other)

This action is used to compare between identifiers to see if they are equal.

Parameters

Return

boolean: true if they are equal, false if they are not equa

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.

Flip()

This action flips the A object with the B objec

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.

GetIndexA()

This action gets the group index of object A.

Return

integer: the group index of object

GetIndexB()

This action gets the group index of object B.

Return

integer: the group index of object

GetTypeA()

This action returns whether object A is colliding with its edge or vertex.

Return

integer: the type of collisio

GetTypeB()

This action returns whether object B is colliding with its edge or vertex.

Return

integer: the type of collisio

Set(Libraries.Game.Collision.CollisionIdentifier2D other)

This action sets the current CollisionIdentifier2D using another CollisionIdentifier2D.

Parameters

SetIndexA(integer indexA)

This action sets the group index of object A.

Parameters

SetIndexB(integer indexB)

This action sets the group index of object B.

Parameters

SetTypeA(integer typeA)

This action sets whether object A is colliding with its edge or vertex.

Parameters

SetTypeB(integer typeB)

This action sets whether object B is colliding with its edge or vertex.
