Libraries.Game.Collision.GlobalCollisionPoints2D Documentation

This class calculates the actual collision points between two 2D objects in global coordinates. Because the collision points stored inside the "LocalCollisionPoints2D" are approximations/relative collision points, the result from this class should be considered as the correct value for collision points.

Actions Documentation

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns a CompareResult. The compare result is either larger if this hash code is larger than the object passed as a parameter, smaller, or equal.

Example Code

use Libraries.Language.Support.CompareResult
        Object o
        Object t
        CompareResult result = o:Compare(t)

Parameters

Return

Libraries.Language.Support.CompareResult: 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(t)

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 obtains the direction of the normal impulse that should be applied object B from object A in global coordinates.

Return

Libraries.Compute.Vector2: the direction of the normal impulse that should be applied.

GetPoints()

This action returns all of the collision points in global coodinates.

Return

Libraries.Containers.Array: all of the collision points.

GetSeparations()

This action returns how much separation is between object A and object B.

Return

Libraries.Containers.Array: how much separation is between object A and object B.

Initialize(Libraries.Game.Collision.LocalCollisionPoints2D collisionPoints, Libraries.Game.Collision.PhysicsPosition2D xfA, number radiusA, Libraries.Game.Collision.PhysicsPosition2D xfB, number radiusB)

This action calculates the variables to GlobalCollisionPoints2D.
