Dialogue with GetKey - Codes

Question

Hello everyone, I'm new to programming but have been able to make a basic demonstration for a game that I am now trying to flesh out a bit. But I keep running into a problem. I tried making a dialog system that ended up looking a bit like this:

public float conversation;

void Update(){

 if (Input.GetKeyDown(KeyCode.Space)){
     panel.SetActive(true);
     text.text="Hello.";
     conversation=1;
 }
 if (conversation==1 && Input.GetKeyDown(KeyCode.Space)){
     conversation=2;
     text.text="What's up?"; 
 }    
 if (conversation==2 && Input.GetKeyDown(KeyCode.Space)){            
     panel.SetActive(false);

}

Basically what happens is I run the script (the trigger works fine so far) and it just skips through the entire dialog to the end. I've tried using .GetKeyDown, .GetKeyUp... and even having a float that would count down (countdown-= Time.deltaTime) and even to only read this part of the script if it is countdown<=0. None of these solutions has worked.

If anyone has ideas, please feel free to share because I'm at a bit of a loss.

There is a single keyword you need to fix this: "else"
Notice that if the first condition is true- you MAKE the second condition true (and so on).
So, if you just add an else before if (conversation==1.. (and all those that follow), it will ensure that only ONE dialog option get executed per call to Update()

Alternatively: you could use the 'return' keyword, at the end of each dialog option. But this assumes there is nothing else in update you need to execute lower down. Also, take a look at the c# case..switch command, perfect for this sort of thing!

Thank you so much! It worked like a charm... It was a bit embarrassing, having all sorts of things run perfectly fine but no functioning dialog system in a story heavy game.
