Check Need EndWhether the trigger is allowed to send an "End" event, if there is no "Begin" event. True = an event will be sent, False = no event will be sent.
Ignore BusyCan the target be used while the player is busy?
Trigger only

A special property that governs whether a node just monitors the instance of a universal Use logic of an interactive object (loot, weapon, etc.) or whether it creates an instance of a script-specific Use logic for non-interactive ones (such as scenery or set-dressing elements that need to be manipulated for gameplay purposes).

  • If TRUE, it will simply fire the event when the player interacts with the target, provided the target is an already universally interactive object by itself (loot, weapon, etc.).
  • If FALSE, it will enable a non-interactive entity, specified as the target, for the player to interact with, then fire the event, if the player enquiries so.

Note, that it is very important to set Trigger only to TRUE, if you specify a universally interactive object (loot, weapon, etc.) as the target. Otherwise the engine will crash.

This is because an object can't handle both USE logic instances (universal and script-specific ones) at the same time. It's one or the other.

Hold CountThe amount of time (seconds) that the player needs to hold the use key/button to utilize an object.
