Retry with Delay

Export

Goal

Use this pattern when an Action may fail temporarily and should be attempted again without retrying every update.

Tree structure

Place a Selector beneath Until Success. Put Try Action first. Put a Sequence containing Wait Before Retry and a task that returns Failure second.

Until Success retries an action through a Selector whose fallback Sequence waits before returning Failure.

How it runs

Try Action runs first. Success ends both the Selector and Until Success. On Failure, the fallback Sequence waits and then returns Failure; Until Success responds by beginning another attempt.

Variations

Until Success has no attempt limit. Use a custom retry Decorator when the operation must return Failure after a fixed number of attempts. For an endless environmental behavior, make sure Try Action is inexpensive and the Wait prevents constant work.

Tasks used in this tree

Until Success, Selector, and Wait plus a result-returning Action from Actions.
