2. How to trigger the player say something after closing a readable. I know how to make him say something after picking something up with a trigger once -> atdm:voice thingy, but when I target the readable instead of the item nothing happens. I know that you can make an objective trigger after closing (or only when opening?) a readable, so I feel like it must be possible on voice as well?
You'd need to make a hidden irreversible objective to close the readable. You need to enter the name of the atdm:voice... entity into the "Completion Target" box so that when the objective completes, it triggers the completion target.
