Object instantiation upon triggerS?

Hello,
I have a scenario where I would like all the triggers that my main camera 'stays' in, to instantiate specific game objects to be at the location(s), rotation(s) of each trigger. My main camera can be inside 2 or more triggers at the same time, which there is a rigidbody and a sphere collider attached to the camera. I am using the OnTriggerStay() function, but that function can only focus on 1 trigger at a time. I would like to have it so the first instance of OnTriggerStay() cleans up the list of triggers in my c# code, and each unique trigger after that re-adds each trigger to the 'list'. Then, I can instantiate game objects to be at those locations and rotations. The scaling doesn't matter and can be the original sizing of the game object, and not the trigger. This will make it so I can have a building, and when I stand at a certain part of the building, only the room I am standing in, gets rendered, and if I am standing near 2 rooms, 2 rooms get rendered... and a room is the game object I'd like to instantiate per trigger. How would I do this? Thank you.

 

From your description, I don't think

OnTriggerStay 

is your best choice. Consider using

OnTriggerEnter 

to instantiate a room, then

OnTriggerExit 

to destroy it.

 

Thank you. That worked.
