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 [code]receiver[/code] object with a signal to the chosen [code]method[/code] name.

To disable the dispatch of a callback from an agent use [method agent_set_callback] again with a [code]null[/code] object as the [code]receiver[/code].
