This event type continually checks if its Conditions have become True, if so the actions will be executed. An event of this type with no Conditions will trigger immediately upon server start.
This is an Ongoing event. It will check if its Conditions have become True each server tick. This means that if the Conditions were True the previous tick and are still True in the current tick, nothing will happen. At least one Condition needs to go back to False for it to become True again.
