Description

A link between two positions onNavigationRegion3Ds that agents can be routed through. These positions can be on the sameNavigationRegion3D or on two different ones. Links are useful to express navigation methods other than traveling along the surface of the navigation mesh, such as ziplines, teleporters, or gaps that can be jumped across.

Property Descriptions

boolbidirectional =true🔗

• voidset_bidirectional(value:bool)

• boolis_bidirectional()

Whether this link can be traveled in both directions or only fromstart_position toend_position.

boolenabled =true🔗

• voidset_enabled(value:bool)

• boolis_enabled()

Whether this link is currently active. Iffalse,NavigationServer3D.map_get_path() will ignore this link.

Vector3end_position =Vector3(0,0,0)🔗

• voidset_end_position(value:Vector3)

• Vector3get_end_position()

Ending position of the link.

This position will search out the nearest polygon in the navigation mesh to attach to.

The distance the link will search is controlled byNavigationServer3D.map_set_link_connection_radius().

floatenter_cost =0.0🔗

• voidset_enter_cost(value:float)

• floatget_enter_cost()

When pathfinding enters this link from another regions navigation mesh theenter_cost value is added to the path distance for determining the shortest path.

intnavigation_layers =1🔗

• voidset_navigation_layers(value:int)

• intget_navigation_layers()

A bitfield determining all navigation layers the link belongs to. These navigation layers will be checked when requesting a path withNavigationServer3D.map_get_path().

Vector3start_position =Vector3(0,0,0)🔗

• voidset_start_position(value:Vector3)

• Vector3get_start_position()

Starting position of the link.

This position will search out the nearest polygon in the navigation mesh to attach to.

The distance the link will search is controlled byNavigationServer3D.map_set_link_connection_radius().

floattravel_cost =1.0🔗

• voidset_travel_cost(value:float)

• floatget_travel_cost()

When pathfinding moves along the link the traveled distance is multiplied withtravel_cost for determining the shortest path.

Method Descriptions

Vector3get_global_end_position()const🔗

Returns theend_position that is relative to the link as a global position.

Vector3get_global_start_position()const🔗

Returns thestart_position that is relative to the link as a global position.

boolget_navigation_layer_value(layer_number:int)const🔗

Returns whether or not the specified layer of thenavigation_layers bitmask is enabled, given alayer_number between 1 and 32.

RIDget_navigation_map()const🔗

Returns the current navigation mapRID used by this link.

RIDget_rid()const🔗

Returns theRID of this link on theNavigationServer3D.

voidset_global_end_position(position:Vector3)🔗

Sets theend_position that is relative to the link from a globalposition.

voidset_global_start_position(position:Vector3)🔗

Sets thestart_position that is relative to the link from a globalposition.

voidset_navigation_layer_value(layer_number:int, value:bool)🔗

Based onvalue, enables or disables the specified layer in thenavigation_layers bitmask, given alayer_number between 1 and 32.

voidset_navigation_map(navigation_map:RID)🔗

Sets theRID of the navigation map this link should use. By default the link will automatically join theWorld3D default navigation map so this function is only required to override the default map.
