as2fm.scxml_converter.scxml_entries.scxml_bt_ticks.BtChildStatus

class as2fm.scxml_converter.scxml_entries.scxml_bt_ticks.BtChildStatus(child_seq_id: str | int, target: str, condition: str | None = None, body: List[ScxmlAssign | ScxmlIf | ScxmlSend] | None = None)

Bases: ScxmlTransition

Process the response received from a BT child.

__init__(child_seq_id: str | int, target: str, condition: str | None = None, body: List[ScxmlAssign | ScxmlIf | ScxmlSend] | None = None)

Generate a BtChildStatus instance.

Parameters:

• child_seq_id – Which BT control node children to tick (relative the the BT-XML file).

• target – The target state to transition to.

• condition – The condition to check before transitioning.

• body – The body to execute before the transition.
