Callback called at the end of the RVO process. If a callback is created manually and the agent is placed on a navigation map it will calculate avoidance for the agent and dispatch the calculated [code]safe_velocity[/code] to the [param receiver] object with a signal to the chosen [param method] name.
[b]Note:[/b] Created callbacks are always processed independently of the SceneTree state as long as the agent is on a navigation map and not freed. To disable the dispatch of a callback from an agent use [method agent_set_callback] again with a [code]null[/code] object as the [param receiver].
Sets the callback [param object_id] and [param method] that gets called after each avoidance processing step for the [param agent]. The calculated [code]safe_velocity[/code] will be dispatched with a signal to the object just before the physics calculations.
[b]Note:[/b] Created callbacks are always processed independently of the SceneTree state as long as the agent is on a navigation map and not freed. To disable the dispatch of a callback from an agent use [method agent_set_callback] again with a [code]0[/code] ObjectID as the [param object_id].
