Overview 4: Processors

Processors

Processors defines the policy that a compound skill uses to access its children. We define the following processors:

• Serial (->): The default processor. Process children in sequence until all succeed. Restarts finished (succeeded/failed) skills. Returns on first occurrence of a running of failed skill.
• SerialStar (->*): Like serial, but keeps memory of which nodes previously succeeded and does not tick them again. The memory index is reset on failure, success or preemption.
• Selector (?): Process children in sequence until one succeeds, ignoring failures. Returns on first occurrence of a running or successful skill.
• SelectorStar (?*): Like Selector, but keeps memory of which nodes previously succeeded and do not tick them again. The memory index is reset on failure, success or preemption.
• ParallelFf (Parallel First Fail): Process children in parallel until all succeed. Stop all processes if a child fails.
• ParallelFs (Parallel First Stop): Process children in parallel until one succeed. Stop all processes if a child finishes (succeeded/fail).

Decorators

Decorators modify the return state of a Processor. The available decorator is currently:

• NoFail: Returns only running or success. Failure state is converted in Success state.
