To make it more clear, I’m new to Unreal and can’t find a video to help, but I want to have trigger boxes that activate certain things (lights going off, etc) but I’m unsure how to change it so it won’t trigger until a certain point. So if I have one at the front door, I don’t want it to be when he enters, but maybe 30 minutes into the game when they leave instead? Hopefully I’ve made that a little understandable, but can someone help because I can’t find an answer online
Hey @WellKnownTV! Welcome to the forums!
So this is something you will want to be in the Level Blueprint. You can call things in the LBP that are in the level - in this case a collision volume (trigger box). You can have the box have a boolean that can activate or deactivate said box, (by using a branch activated true/false by that boolean).
In the LBP, when something happens, you can call those boxes and set their boolean that allows them to work to True. 
You just need some sort of additional trigger to activate an event or function to do so, on the Level blueprint itself.

Hey @WellKnownTV! Welcome to the Forums!
To add on a bit more to what @Mind-Brain has explained above, if you are planning to move from level to level, these variables can be saved using a game instance. So if your main level is a hub world for example, if you need to move to a different map to get another plot point or item to progress, you can come back to this level and still update as intended.
Check out this non-Epic tutorial showing a basic example of how to use game instances:

Thank you so much for this! I thought it was a boolean but wasn’t too confident on how to do it, but this helps a lot!
Thank you for sending this video link, I was thinking of doing this if nothing else worked, and now I can use both methods, so thank you
