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].
Sets the callback that gets called after each avoidance processing step for the [param agent]. The calculated [code]safe_velocity[/code] will be passed as the first parameter 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 an empty [Callable].
