[Script] Console Rich Text Messages.

Send lines of text in Rich Text format.

The lines are shown from a GUI.BeginScrollView element that allows us to move through the list.

This would be the console code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3.  
4. public class Console : MonoBehaviour {
5.  
6.     public Font font;
7.     public int sizeFont = 15;
8.     public FontStyle styleFont = FontStyle.Normal;
9.     public Color colorFont = Color.grey;
10.     public TextAnchor aligment = TextAnchor.UpperLeft;
11.     public float heightLine = 20f;
12.     public Rect rectConsole = new Rect(10f,10f,400f,100f);
13.  
14.     List<string> linesConsole = new List<string>();
15.     int numLines;
16.  
17.     GUIStyle style = new GUIStyle();
18.     Rect rectLine, viewScroll;
19.     Vector2 positionScroll = Vector2.zero;
20.  
21.  
22.     void Start(){
23.  
24.         this.style.font = this.font;
25.         this.style.fontSize = this.sizeFont;
26.         this.style.fontStyle = this.styleFont;
27.         this.style.normal.textColor = this.colorFont;
28.         this.style.alignment = this.aligment;
29.         this.style.richText = true;
30.         this.numLines = this.linesConsole.Count;
31.         this.rectLine = new Rect(this.rectConsole.x+5f,0f,this.rectConsole.width-10f,20f);
32.         this.viewScroll = new Rect(0,0,this.rectConsole.width-25f,this.rectConsole.height);
33.     }
34.  
35.     void Update(){
36.  
37.         if(this.numLines!=this.linesConsole.Count){
38.  
39.             this.numLines = this.linesConsole.Count;
40.             this.viewScroll.height = Mathf.Max(this.rectConsole.height,(this.numLines+1)*this.heightLine);
41.             this.viewScroll.y = this.rectConsole.height-this.viewScroll.height;
42.             this.positionScroll.y = this.viewScroll.height-this.rectConsole.height;
43.  
44.         }
45.  
46.     }
47.  
48.     void OnGUI(){
49.  
50.         GUI.Box(this.rectConsole,"");
51.  
52.         this.positionScroll = GUI.BeginScrollView(this.rectConsole,this.positionScroll,this.viewScroll);
53.  
54.         float LowMargin = this.rectConsole.y + this.rectConsole.height - this.heightLine;
55.         float UpLimit = this.positionScroll.y + this.viewScroll.y - this.heightLine;
56.         float LowLimit = UpLimit + this.rectConsole.height;
57.  
58.         for(int i=1;i<=this.linesConsole.Count;i++){
59.  
60.             this.rectLine.y = LowMargin-i*this.heightLine;
61.             if(this.rectLine.y<UpLimit) break;
62.             if(this.rectLine.y>LowLimit) continue;
63.             GUI.Label(this.rectLine,this.linesConsole[this.linesConsole.Count-i],this.style);
64.  
65.         }
66.  
67.         GUI.EndScrollView();
68.  
69.     }
70.  
71.     public void AddLine(string linea){
72.  
73.         this.linesConsole.Add(linea);
74.  
75.     }
76.  
77. }
78.  

After, from other scripts you can add lines to the console by AddLine (string line) function, for example:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class controlConsole : MonoBehaviour {
5.  
6.     public Console console;
7.     public Color colorPlayer = Color.red;
8.     public string namePlayer = "Player";
9.     public Rect rectTextField = new Rect(100f,500f,500f,30f);
10.     public int maxCharactersTextField = 50;
11.  
12.     string line="";
13.  
14.     void OnGUI(){
15.  
16.         string str = GUI.TextField(this.rectTextField,this.line,this.maxCharactersTextField,GUI.skin.textField);
17.  
18.         if(str.Contains("\n")){
19.  
20.             if(this.line.Length>0){
21.  
22.                 console.AddLine("<size=12><color=#"+RGBToHex(this.colorPlayer)+">["+this.namePlayer+"]</color></size>"+this.line);
23.                 this.line="";
24.  
25.             }
26.  
27.         } else this.line = str;
28.  
29.     }
30.  
31.     static string RGBToHex (Color color) {
32.  
33.         string Hex = "0123456789abcdef";
34.  
35.         int red   = (int)(color.r * 255f);
36.         int green = (int)(color.g * 255f);
37.         int blue  = (int)(color.b * 255f);
38.         int alfa  = (int)(color.a * 255f);
39.  
40.         return (Hex[red/16]+Hex[red%16]+Hex[green/16]+Hex[green%16]+Hex[blue/16]+Hex[blue%16]+Hex[alfa/16]+Hex[alfa%16]).ToString();
41.  
42.     }
43.  
44. }
