    Class InteractionListener

    Listener for interaction events between two interactors.

    Fires when two objects matching options1 and options2 start, continue, or stop interacting with each other according to interactionType.

    Valid events: CbEvent.BEGIN, CbEvent.ONGOING, CbEvent.END.

    • BEGIN fires once when the interaction starts.
    • ONGOING fires every simulation step while the interaction persists.
    • END fires once when the interaction ends.
    const listener = new InteractionListener(
      CbEvent.BEGIN,
      InteractionType.COLLISION,
      playerType,
      groundType,
      (cb) => { console.log('player landed'); },
    );
    space.listeners.add(listener);

    • get precedence(): number

      Execution priority of this listener relative to other listeners for the same event and objects. The direction depends on the listener type (inherited from Haxe nape):

      • BodyListener / ConstraintListener: higher values run first; on a tie the listener added last runs first.
      • InteractionListener / PreListener: lower values run first; on a tie the listener added first runs first. When several PreListeners return a flag for the same pair the last one called wins — so the highest precedence has the final say.

      Returns number
