Essentially, in my project there is a prefab, known as a "latch". The latch can be instantiated by players, leading to an unknown amount of latches. The problem is that each latch needs to have a separate global variable, or some way to communicate with the scene's other objects while distinguishing itself from the other prefabs.

Now, I have an idea, but I don't know the coding to create it - or whether it's possible. Could a new latch, upon entrance to the scene, "count" all the other latches then make a new global variable based upon how many other latches currently exist? (Example: If the latch is the 64th, then it would create a global variable "latch64".) Can this be done? If so, how? If not, does anybody else have any ideas?
