hi.
if you will have many triggers to interact you should not do trigger events on each object, but have a trigger on your player to detect those objects.
if you get many triggers looking for player, it will hit performance.
you can use tags like Door / Key / Item / etc to know what you detect, and you can store the object that you detected.
Then on those object you can set a fsm Called (for Example) Data.
And you can access then with Get/Set Fsm actions and/or Send event by name (for example to open a door)
