How to wait for user input in a Turn-Based Game

Questions & Answers
1

Hope I can find some help here (once again) after thinking a lot myself about the problem without finding a solution…

So here’s what I want to do: I have a turn-based battle system that is based on a “big” while-loop. In this while-loop I call a method “Move();”, this method will show the GUI if the mob is a player or get a move automatically if the mob is a npc. The problem I get here is that I don’t know how I could freeze/stop the code here until the user has pressed a GUI.button (and thus select a move). The code in the while-loop will just continue to the next part of the code and everything will become a mess (since the players move = null).

What I’ve tried: Creating a new “IEnumerator Wait()” that will “yield return new WaitForSeconds(0.1f);” while the GUI is shown (the GUI will dissappear after a GUI.Button is clicked on) (I would call Wait() from Move()). This however does not work since the while-loop here does not in fact stop the “big” while-loop which it is called from from continuing.
If it was possible I would just call a method that shows the GUI.Buttons and then requires a “return”, but this is not possible since the only(?) way to show GUI.Buttons is through “void OnGUI()”.

EDIT: The “big” while-loop can not be a Enumerator since the class is not derived from MonoBehaviour (and can thus not use StartCorountine). I tried to rewrite it so it was based of MonoBehaviour but ran in to all sorts of errors when trying to call it.

EDIT #2: I have found a way to successfully make the “big” while-loop a coroutine and execute it :slight_smile: But the question remains how I could wait for a user-input through GUI.Button.

ouch, what a messy method…

you can try something like this

//pseudocode

bool hasPlayermoved  = false;



void move()
{
if(hasplayerMoved)
{
//do my stuff because the player has moved
//at the end of this function you can say 
hasPlayerMoved = false;
}
}

you can set hasPlayerMoved after the player has selected their move. if this Boolean is false, unity will ignore all of the code inside the if(hasPlayerMoved) curly braces.

hope this helps a bit.
