Types

type Advanced 

type Advanced = class

Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.

type Any 

type Any interface {
	gd.IsClass
	AsNavigationPathQueryParameters2D() Instance
}

type Extension 

type Extension[T gdclass.Interface] struct{ gdclass.Extension[T, Instance] }

Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension

func (*Extension[T]) AsNavigationPathQueryParameters2D 

func (self *Extension[T]) AsNavigationPathQueryParameters2D() Instance

func (*Extension[T]) AsObject 

func (self *Extension[T]) AsObject() [1]gd.Object

func (*Extension[T]) AsRefCounted 

func (self *Extension[T]) AsRefCounted() [1]gd.RefCounted

type ID 

type ID Object.ID

ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.

func (ID) Instance 

func (id ID) Instance() (Instance, bool)

type Instance 

type Instance [1]gdclass.NavigationPathQueryParameters2D

Instance of the class with convieniently typed arguments and results. 

var Nil Instance

Nil is a nil/null instance of the class. Equivalent to the zero value.

func New 

func New() Instance

func (Instance) AsNavigationPathQueryParameters2D 

func (self Instance) AsNavigationPathQueryParameters2D() Instance

func (Instance) AsObject 

func (self Instance) AsObject() [1]gd.Object

func (Instance) AsRefCounted 

func (self Instance) AsRefCounted() [1]gd.RefCounted

func (Instance) ExcludedRegions 

func (self Instance) ExcludedRegions() []RID.Any

The list of region Resource.IDs that will be excluded from the path query. Use NavigationRegion2D.GetRid to get the Resource.ID associated with a NavigationRegion2D node.

Note: The returned array is copied and any changes to it will not update the original property value. To update the value you need to modify the returned array, and then set it to the property again.

func (Instance) ID 

func (self Instance) ID() ID

func (Instance) IncludedRegions 

func (self Instance) IncludedRegions() []RID.Any

The list of region Resource.IDs that will be included by the path query. Use NavigationRegion2D.GetRid to get the Resource.ID associated with a NavigationRegion2D node. If left empty all regions are included. If a region ends up being both included and excluded at the same time it will be excluded.

Note: The returned array is copied and any changes to it will not update the original property value. To update the value you need to modify the returned array, and then set it to the property again.

func (Instance) Map 

func (self Instance) Map() RID.NavigationMap2D

The navigation map Resource.ID used in the path query.

func (Instance) MetadataFlags 

func (self Instance) MetadataFlags() PathMetadataFlags

Additional information to include with the navigation path.

func (Instance) NavigationLayers 

func (self Instance) NavigationLayers() int

The navigation layers the query will use (as a bitmask).

func (Instance) PathPostprocessing 

func (self Instance) PathPostprocessing() PathPostProcessing

The path postprocessing applied to the raw path corridor found by the PathfindingAlgorithm.

func (Instance) PathReturnMaxLength 

func (self Instance) PathReturnMaxLength() Float.X

The maximum allowed length of the returned path in world units. A path will be clipped when going over this length. A value of 0 or below counts as disabled.

func (Instance) PathReturnMaxRadius 

func (self Instance) PathReturnMaxRadius() Float.X

The maximum allowed radius in world units that the returned path can be from the path start. The path will be clipped when going over this radius. A value of 0 or below counts as disabled.

Note: This will perform a circle shaped clip operation on the path with the first path position being the circle's center position.

func (Instance) PathSearchMaxDistance 

func (self Instance) PathSearchMaxDistance() Float.X

The maximum distance a searched polygon can be away from the start polygon before the pathfinding cancels the search for a path to the (possibly unreachable or very far away) target position polygon. In this case the pathfinding resets and builds a path from the start polygon to the polygon that was found closest to the target position so far. A value of 0 or below counts as unlimited. In case of unlimited the pathfinding will search all polygons connected with the start polygon until either the target position polygon is found or all available polygon search options are exhausted.

func (Instance) PathSearchMaxPolygons 

func (self Instance) PathSearchMaxPolygons() int

The maximum number of polygons that are searched before the pathfinding cancels the search for a path to the (possibly unreachable or very far away) target position polygon. In this case the pathfinding resets and builds a path from the start polygon to the polygon that was found closest to the target position so far. A value of 0 or below counts as unlimited. In case of unlimited the pathfinding will search all polygons connected with the start polygon until either the target position polygon is found or all available polygon search options are exhausted.

func (Instance) SimplifyPath 

func (self Instance) SimplifyPath() bool

If true a simplified version of the path will be returned with less critical path points removed. The simplification amount is controlled by SimplifyEpsilon. The simplification uses a variant of Ramer-Douglas-Peucker algorithm for curve point decimation.

Path simplification can be helpful to mitigate various path following issues that can arise with certain agent types and script behaviors. E.g. "steering" agents or avoidance in "open fields".

type PathPostProcessing 

type PathPostProcessing int //gd:NavigationPathQueryParameters2D.PathPostProcessing

const (
	// Applies a funnel algorithm to the raw path corridor found by the pathfinding algorithm. This will result in the shortest path possible inside the path corridor. This postprocessing very much depends on the navigation mesh polygon layout and the created corridor. Especially tile- or gridbased layouts can face artificial corners with diagonal movement due to a jagged path corridor imposed by the cell shapes.
	PathPostprocessingCorridorfunnel PathPostProcessing = 0
	// Centers every path position in the middle of the traveled navigation mesh polygon edge. This creates better paths for tile- or gridbased layouts that restrict the movement to the cells center.
	PathPostprocessingEdgecentered PathPostProcessing = 1
	// Applies no postprocessing and returns the raw path corridor as found by the pathfinding algorithm.
	PathPostprocessingNone PathPostProcessing = 2
)
