Struct veloren_common::path::Chaser

pub struct Chaser {
    last_search_tgt: Option<Vec3<f32>>,
    route: Option<(Route, bool)>,
    astar: Option<Astar<Vec3<i32>, DefaultHashBuilder>>,
}

A self-contained system that attempts to chase a moving target, only performing pathfinding if necessary

Fields

last_search_tgt: Option<Vec3<f32>>

route: Option<(Route, bool)>

bool indicates whether the Route is a complete route to the target

astar: Option<Astar<Vec3<i32>, DefaultHashBuilder>>

We use this hasher (AAHasher) because: (1) we care about DDOS attacks (ruling out FxHash); (2) we don’t care about determinism across computers (we can use AAHash).

Implementations

impl Chaser

pub fn chase<V>( &mut self, vol: &V, pos: Vec3<f32>, vel: Vec3<f32>, tgt: Vec3<f32>, traversal_cfg: TraversalConfig, ) -> Option<(Vec3<f32>, f32)>

where V: BaseVol<Vox = Block> + ReadVol,

Returns bearing and speed Bearing is a Vec3 dictating the direction of movement Speed is an f32 between 0.0 and 1.0
