_RollbackSimulationServer

Inherits: Node

Runs gameplay simulation during rollback

Description

Rollback involves restoring the game state to an earlier point in time and re-running game logic from there. This class tracks which nodes participate in rollback, which of them need to be actually simulated, and runs the simulation itself.

Node simulation honors scene tree order. Processing order and physics processing order are not considered.

To participate in rollback, call register() using the method to call to simulate the node. Only one Callable can be actively registered per node.

Methods

void	deregister_rollback_input(Node node, Node input)
bool	is_predicting_current()
Object	get_simulated_object()
void	simulate(float delta, int tick)

Method Descriptions

void register ( Callable callback )

---

void deregister_rollback_input ( Node node, Node input )

Deregister input from providing input for node

---

bool is_predicting_current ( )

Return true if the currently simulated node is being predicted

---

Object get_simulated_object ( )
