Member Function Documentation

DrawGizmos()

override void AC.NavigationEngine_PolygonCollider.DrawGizmos ( GameObject navMeshOb )

virtual

Draws gizmos in the Scene/Game window.

Parameters

navMeshOb

The NavigationMesh gameobject to draw gizmos for

Reimplemented from AC.NavigationEngine.

GetPointNear()

override Vector3 AC.NavigationEngine_PolygonCollider.GetPointNear ( Vector3 point, float minDistance, float maxDistance )

virtual

Finds a random position surrounding a given point on a NavMesh.

Parameters

point	The given point on the NavMesh
minDistance	The minimum distance between the given point and the random point
maxDistance	The maximum distance between the given point and the random point

Returns

A random position surrounding the given point. If a suitable point is not found, the original point will be returned.

Reimplemented from AC.NavigationEngine.

GetPointsArray()

override Vector3[] AC.NavigationEngine_PolygonCollider.GetPointsArray ( Vector3 startPosition, Vector3 targetPosition, AC.Char _char = null )

virtual

Calculates a path between two points.

Parameters

startPosition	The start position
targetPosition	The intended end position
_char	The character (see Char) who this path is for (only used in PolygonCollider pathfinding)

Returns

The path to take, as an array of Vector3s.

Reimplemented from AC.NavigationEngine.

GetPrefabName()

override string AC.NavigationEngine_PolygonCollider.GetPrefabName ( )

virtual

Gets the name of a "helper" prefab to list in the Scene Manager.

Returns

The name of the prefab to list in SceneManager. The prefab must be placed in the Assets/AdventureCreator/Prefabs/Navigation folder. If nothing is returned, no prefab will be listed.

Reimplemented from AC.NavigationEngine.

NavigationMeshGUI()

override NavigationMesh AC.NavigationEngine_PolygonCollider.NavigationMeshGUI ( NavigationMesh _target )

virtual

Provides a space for any custom Editor GUI code that should be displayed in the NavigationMesh inspector.

Reimplemented from AC.NavigationEngine.

OnReset()

override void AC.NavigationEngine_PolygonCollider.OnReset ( NavigationMesh navMesh )

virtual

Called when the scene begins or is reset.

Parameters

navMesh

The NavigationMesh that is active in the scene.

Reimplemented from AC.NavigationEngine.

ResetHoles()

override void AC.NavigationEngine_PolygonCollider.ResetHoles ( NavigationMesh navMesh )

virtual

Integrates all PolygonCollider2D objects in the polygonColliderHoles List into the base PolygonCollider2D shape. This is called automatically by AddHole() and RemoveHole() once the List has been amended

Reimplemented from AC.NavigationEngine.

SceneSettingsGUI()

override void AC.NavigationEngine_PolygonCollider.SceneSettingsGUI ( )

virtual

Provides a space for any custom Editor GUI code that should be displayed in SceneManager.

Reimplemented from AC.NavigationEngine.

TurnOn()

override void AC.NavigationEngine_PolygonCollider.TurnOn ( NavigationMesh navMesh )

virtual

Enables the NavMesh so that it can be used in pathfinding.

Parameters

navMeshOb

The NavigationMesh gameobject to enable

Reimplemented from AC.NavigationEngine.
