Struct de_pathing::fplugin::FinderPlugin

pub struct FinderPlugin;

This plugin registers systems which automatically update the path finder when static solid objects are added or removed from the world.

World Update

• Each solid static object’s ichnography (a convex polygon) is offset by some amount. See crate::exclusion.

• Overlapping polygons from the previous steps are merged – their convex hull is used. These are called exclusion areas.

• Whole map (surface) is triangulated with Constrained Delaunay triangulation (CDT). All edges from the exclusion areas are used as constrains. See crate::triangulation.

• Triangles from inside the exclusion areas are dropped, remaining triangles are used in successive steps.

• A visibility sub-graph is created. The each triangle edge is connected with all neighboring triangle edges. See crate::finder::PathFinder::from_triangles.

Trait Implementations

impl Plugin for FinderPlugin

fn build(&self, app: &mut App)

Configures the [App] to which this plugin is added.

fn ready(&self, _app: &App) -> bool

Has the plugin finished its setup? This can be useful for plugins that need something asynchronous to happen before they can finish their setup, like the initialization of a renderer. Once the plugin is ready, finish should be called.

fn finish(&self, _app: &mut App)

Finish adding this plugin to the [App], once all plugins registered are ready. This can be useful for plugins that depends on another plugin asynchronous setup, like the renderer.

fn cleanup(&self, _app: &mut App)

Runs after all plugins are built and finished, but before the app schedule is executed. This can be useful if you have some resource that other plugins need during their build step, but after build you want to remove it and send it to another thread.

fn name(&self) -> &str

Configures a name for the [Plugin] which is primarily used for checking plugin uniqueness and debugging.

fn is_unique(&self) -> bool

If the plugin can be meaningfully instantiated several times in an [App], override this method to return false.
