}
Fields§
§model: Model<Vertex>
§stale_flag: bool
Used to garbage-collect tethers that no longer exist.
Because a tether is not an entity, but instead a relationship between
two entities, there is no single ‘event’ that we can listen to in
order to determine that a tether has been broken. Instead, every tick,
we go through the set of tethers that we observe in the world and
mark their entries in the tethers
map below with a flag.
At the end of the tick, every unmarked tether in the tethers
map below
can be deleted.
Every tick, the ‘alive’ state of the flag flips between true
and
false
to avoid the need to wastefully reset the flag of every
alive tether on each tick (this is a common optimisation in some garbage
collection algorithms too).
