This is my first time using Unity (and my third time creating a game in general), so I hope I can provide the needed information to solve this problem.

I want to create a turnbased system for my 2D Top/Down Rougelike. After the Generation of the dungeon, there will spawn x Enemys based of choosen difficulty and choosen quest.

How should each turn look like?
Player for example is a Orc, so he gets 7 movement. (meaning he can move 7 tiles.)
  In his turn he can move for example 3 tiles, then attack, 2 tiles, use a potion and then uses his last 2 tiles of movement. And then he presses "End Turn" and then the enemys go through there turns (based of which typ of creature there are). The Player can skip his turn completly, attack and dont move or only move. But he always needs to press the "End Turn" Button.

What I would do, too solve this issue:
I would create a boolean for every single enemy and the player, then turn them true or false. And whatever boolean is true, that person can do his turn. But to check this, I would need to put it in the "Update" method. So on every frame there would be x+1 checks (all Enemys plus player), who can move or not.

A second idea would be, to put the player and the enemy in a array, sort by speed variable (so who goes first, and who goes last) and then I would have my turn order without any boolean. But this still leaves the question, how I would prevent the player of moving or doing stuff, while it is not there turn.

I dont thing any of them would be a good idea. Since I use now Unity, I hope there is a better option for this. And just a heads up, english isnt my first language, but I hope you can understand me. I will happily answer any question.
