_NetworkHistoryServer

Inherits: Node

Tracks the history of objects' properties

Description

Specifically, history is stored for rollback state properties, rollback input properties, and synchronized state properties.

Keeping history lets rollback restore earlier game states for resimulation, and enables _NetworkSynchronizationServer to send diff states by comparing against historical data.

Method Descriptions

void register_rollback_state ( Node node, NodePath property )

Register a rollback state property

---

void deregister_rollback_state ( Node node, NodePath property )

Deregister a rollback state property

---

void register_rollback_input ( Node node, NodePath property )

Register a rollback input property

---

void deregister_rollback_input ( Node node, NodePath property )

Deregister a rollback input property

---

void register_sync_state ( Node node, NodePath property )

Register a synchronized state property

---

void deregister_sync_state ( Node node, NodePath property )

Deregister a synchronized state property

---

void deregister ( Node node )

Deregister a node, no longer tracking any property it had registered using any of the register_*() methods

---

void ignore ( Node subject )

Do not record subject

Can be used in _rollback_tick() in case node prediction is enabled, but state can't be reasonably predicted.

Subjects stay ignored until flush_ignores() is called. This is done by default after every rollback tick.

---

void flush_ignores ( )

Clear the list of ignored subjects

Calling this method undoes all previous ignore() calls.

---

int get_latest_state_tick_for ( Array subjects, int tick )

Return the latest tick where any of the subjects had rollback state data available

---

int get_state_age_for ( Array subjects, int tick )

Return how old is the latest rollback state data for any of the subjects, in ticks

---

int get_latest_input_for ( Array subjects, int tick )

Return the latest tick where any of the subjects had rollback input data available

---

int get_input_age_for ( Array subjects, int tick )

Return how old is the latest rollback input data for any of the subjects, in ticks

---
