Question Xbox controllers order persistency

Hi, i am trying to create a system to be able to have a dynamic amount of xbox controllers playing the game.

I had something working by calling Input.GetJoystickNames() and using the position of non empty names in the array to determine the joystick number. But there is a problem with this approach.

Lets say for example i have 2 controllers and my name array will look like that

Code (CSharp):

1. string[] name = Input.GetJoystickNames()
2.  
3. name[0] "Xbox Controller" // Player 0 using joystick 0
4. name[1] "Xbox Controller" // Player 1 using joystick 1

To access the input of the players i use the positions in the array as their "joystick index".
in this case, Players 0 and 1 will respectively access the inputs from joysticks 0 and 1, this worked even when the array was filled with "ghost controllers" (this is how we will call the empty names Input.GetJoystickNames() returns when controllers are plugged / unplugged) ex:

Code (CSharp):

1. name[0] ""
2. name[1] "Xbox Controller" // Player 0 using joystick 1
3. name[2] ""
4. name[3] "Xbox Controller" // Player 1 using joystick 3

At first this used to work exactly as i wanted i to, when i disconnected / reconnected a controller, the name at its position in the array became empty and upon reconnection, it would reappear at the same position, there was consistency.

MY PROBLEM :

After a bit of testing messing with reconnections / disconnections, i realised "sometimes" the controller don't go back at the same place in the array but instead, gets a new place further, leaving his first position apparently empty, forever.

I looked if it was possible to find some "controller serial number" or some kind of unique and persistant ID assigned to each controllers but i couldnt find answers so here i am. Thank you for your help.

 

I think i found a solution, didin't realised there was a new input system

¯\_(ツ)_/¯
