Reveal next letter on Input.anyKeyDown

Questions & Answers

Hey all,

I’m very new to code so please forgive my noobish ways. I’m trying to write a simple code that reveals the next letter in a paragraph of text with Input.anyKeyDown. Basically I want it to show one letter at a time no matter the key you press.

While searching for an answer I came across an AutoType script. With many failed attempts to edit it for my needs I decided to come here to ask for help.

using UnityEngine;
using System.Collections;

public class TextAuto : MonoBehaviour 
{

		public float letterPause = 0.05f; //NOT NEEDED
		public GUIStyle font;
		string message;
		string text;
		
	void Start (){

			message = "Welcome new warrior! This is a blue screen, you must fight your way out! " +
				"Without any hands or other parts. This may take some time...";
			text = "";
			//StartCoroutine(TypeText());
			
		}
		
	IEnumerator TypeText (){
			foreach (char letter in message.ToCharArray()) 
			{
				text += letter;
					
				yield return 0;
				yield return new WaitForSeconds (letterPause);
			}      
		}
		
	void OnGUI(){
			GUI.Label(new Rect(0, 0, 256, 1024), text, font);    
	}
		
	void Update(){
			
		if(Input.GetKeyDown (KeyCode.Return)){
				
			StopAllCoroutines();
				text = message;
		}
	   

	}
}

Cheers

I see no need for a coroutine; it looks like you are trying to use the coroutine to time the new characters output, rather than base it on a keypress, as you said was desired.

I would try something like this (I have not complied the below, so it may have typos):

int counter;

void Start (){
 
             message = "Welcome new warrior! This is a blue screen, you must fight your way out! " +
                 "Without any hands or other parts. This may take some time...";
             text = "";
             counter=0;
             
         }

Update()
{

    if(Input.anyKeyDown)
    {
      text += message[counter++];
    }
}
