Struct EntityScheduler 

pub struct EntityScheduler<T> {
    pub time: i64,
    /* private fields */
}

The entity manager’s buckets: which entities are visited in each simulation iteration, and the time each one has had since its last visit. T is the caller’s value for an entity.

Fields

time: i64

The current game time.

Implementations

impl<T> EntityScheduler<T>

where T: Copy,

pub fn register(&mut self, value: T, bucket: usize) -> usize

Register an entity in a bucket, at the end, with its last visit set to now. Returns its handle. Bucket 6 means “not scheduled”: the entity is registered but never visited.

Original: FUN_1400c9d70.

pub fn register_extra(&mut self, value: T, bucket: usize) -> usize

register in the extra handle space (from EXTRA): the same buckets, cursors and timing, without taking a placed entity’s index.

pub fn contains(&self, handle: usize) -> bool

Whether handle was registered.

pub fn bucket(&self, bucket: usize) -> &[usize]

A bucket’s handles in visiting order.

pub fn cursor(&self, bucket: usize) -> usize

A bucket’s cursor, the slot its next visit starts at.

pub fn schedule(&self, handle: usize) -> (usize, i64)

An entity’s bucket (6: none) and last visit time.

pub fn restore( &mut self, order: &[Vec<usize>; 5], cursors: [usize; 5], saved: &[(usize, usize, i64)], )

A saved game’s bucket lists, cursors and schedules: order lists each bucket’s handles in its saved order, saved each saved entity’s bucket (6: none) and last visit time. Registered entities the save does not know keep their bucket and follow its listed ones.

pub fn take_visits(&mut self) -> Vec<(T, i64)>

The values visited since the last call, each with the time since its previous visit, in visiting order (the bucket pass’s scheduled components run for these).

pub fn advance(&mut self, dt: f32)

Advance the clock by dt seconds. Then the caller visits each bucket, then removes the entities that were deleted.

Original: FUN_1400c9560 (the clock).

pub fn visit_bucket(&mut self, bucket: usize) -> Vec<(usize, T, i64)>

Visit one bucket: from its cursor, at most its quota of entities or one full round. Each visit gives the entity’s handle, value and the time since its own last visit. Entities registered during the visits wait until the next iteration.

Original: FUN_1400c9560.

pub fn remove(&mut self, id: usize)

Remove an entity: it swaps places with the last entity of its bucket, and the cursor does not move. Call it after all visits of the iteration, as the original deletes late.

Original: FUN_1400c8db0.

Trait Implementations

impl<T> Default for EntityScheduler<T>

where T: Copy,

fn default() -> EntityScheduler<T>

Returns the “default value” for a type.
