Levers and Interactable Objects

Overview

Interactable objects are defined through a C++ class in bulkobjects/psinteractableactor.cpp , this class is blueprint enabled, so you can see it from the editor. In the editor there are items you can use in Blueprints/InteractableActors.

There are different types of actors like:

• lights (can be turned on and off)
• doors with 2 states (open / close)
• doors with 3 states (open on the outside / closed / open on the inside)
• gates with 2 states (open and close) , you can set the direction to be left/right/up/down. This will determine the direction the door will slide when activated
• levers with 2 states (up and down).

All interactable actors have these properties:

• InteractDistance : player distance required to use the item
• SoundOnToggle : sound played when you use the item
• linkedActors : actors which will be triggered when using this item (must be also interactable actors)
• DisableDirectInteraction : if set to true it prevents the player to use this item. Can be used for gates, which are triggered by a lever, and we dont want the player to be able to open the gate directly.
• linkedActorsToggles : List of actors which toggled this item. We keep track of this to then toggle the final item. Example for a door requiring multiple levers to be opened, you will list here all the levers.
• trapProperties: if trapped, these are the properties, see Traps
