adding things to an array at runtime

playerCamera = GameObject.FindWithTag(“Player”).transform;

i need to find away to generate terrain around a player currently i do it based on the location of the player but when a second connects it dosent generate around him, my theroy is you add new players to an array and generate the terrrain around the contents of the array is this correct? and if so how would i do it

Well to add things to the array simply callback the number, for instance myArray[2]= MyObject; MyObject will be set on the slot number 2.

If you mean to increase the array list, I do not know how to do that on the fly.
