setEnterCallback(%status)

I would think that this method for the trigger would be reqiuired in order to "allow the trigger to be on".

I am studying the Rainy Day Tut and it's trigger has no reference to this in it's code.

///trigger method
setEnterCallback(%status)

///a working trigger
if (!isObject(WateringBehavior))
{
   %template = new BehaviorTemplate(WateringBehavior);
   
   %template.friendlyName = "Watering Behavior";
   %template.behaviorType = "Trigger";
   %template.description  = "Defines when to begin watering";
}

function WateringBehavior::onEnter(%this, %object)
{
   %object.startWatering();
}

function WateringBehavior::onLeave(%this, %object)
{
   %object.endWatering();
}
