How to Create a personalized kind of ".ToString()" with parameters ?

Hello there^^.

I'm not sure the description of the thread is exact but basically what i try to do is to create something like this (in C#) :

Code (CSharp):

1. float number = 50000000;
2. string tmpNumber = "";
3.  
4.    method .ToString("Optimized")
5. {
6.     if (number > 1000){
7.         tmpNumber = (int)(number/1000)+" Mega";
8.     }
9.     if (number > 1000000){
10.         tmpNumber = (int)(number/1000000)+" Giga";
11.     }
12.     if (number > 1000000000){
13.         tmpNumber = (int)(number/1000000000)+" Tera";
14.     }
15.     // display that tmpNumber instead of Number
16. }
17.  
18. //textNumber = number.ToString("Optimized");
19. Debug.Log(number.ToString("Optimized"));
20. // i should see   " 50 Giga"

I want to automatically with the .StringOptimized, display string depending of their lenght, for Display Damages purpose.
The thing is i have no idea about how to create in Unity something like this personnalized .Component, as a .ToString() or so.

If someone can enlight me about this i would be really gratfull (i'm not asking for my complete component but at least a way to create some personnalized .Component close to this^^.
Thanks.

Baku.

 

not a js user... so there might be typos in here but something like this:

Code (csharp):

1.  
2. //unityscript
3.  
4. function ToStringOptimized(float f) : string
5. {
6.     string tmpNumber = "";
7.  
8.     if (f > 1000)
9.     {
10.         tmpNumber = (int)(f/1000)+" Mega";
11.     }
12.     if (f > 1000000)
13.     {
14.         tmpNumber = (int)(f/1000000)+" Giga";
15.     }
16.     if (f > 1000000000)
17.     {
18.         tmpNumber = (int)(f/1000000000)+" Tera";
19.     }
20.    
21.     return tmpNumber;
22. }
23.  
24.  
25.  
26. float number = 50000000;
27. string textNumber = "";
28. textNumber = ToStringOptimized(number);
29. Debug.Log(textNumber);
30.  

 

hi, i'm also no JS user but i don't think you have to pass a float in JS! In c# in works like this:

Code (CSharp):

1. float number = 50000000;
2. string tmpNumber = "";
3.     public string ToOptimizedString()
4. {
5.     if (number > 1000){
6.         tmpNumber = (int)(number/1000)+" Mega";
7.     }
8.     if (number > 1000000){
9.         tmpNumber = (int)(number/1000000)+" Giga";
10.     }
11.     if (number > 1000000000){
12.         tmpNumber = (int)(number/1000000000)+" Tera";
13.     }
14. return tmpNumber;
15.     // display that tmpNumber instead of Number
16. }

hope this helps

EDIT: uh but is see that you should use ELSE IF statements... otherwise every if statement is true for big numbers

 

oh, good point... might be an idea to do this with a switch statement based on the "power" of the number rather than discrete if/if else statements


edit: I actually had to look it up... my math teacher would be horrified! Mathf.Log10()

http://docs.unity3d.com/ScriptReference/Mathf.Log10.html

 

Ho i'm sorry it was supposed to be a C# script, i said "Function" because its not a method but something else i though.
But i'ts not really a method function i try to do, its a permanent ".ToStringOptimized" i want to add in Unity to be able to call it in any script like we can use a .ToString().

I basically know how to convert a string like this with a normal method, but i want to create/add in for exemple "
UnityEngine;
or System.Collections;
or System.Collections.Generic;"
Add this .ToStringOptimized as a permanent attribut i can use everywhere, not calling a method everytime, if you see.



I'm gonna try your solutions see if it works and get back to you, thanks a lot^^.

 

you can use "ToString()" on objects because they have implemented that function. It's not one "central" function.

You could look into setting up a static class with this as a static function (pass number by parameter in that case). You'd only need to set that up once in your project

i.e.

Code (csharp):

1.  
2. SomeStaticClass.ToOptimizedString(number);
3.  

then it's like using Mathf.



The interface that needs to be implemented for ToString

Hey Bakudan, my solution should work for you, you just have to implement the ToStringOptimized() method i wrote in every class where you want to use it. but i think this should only be 1 or just a few. It's the same as the ToString() Method... it is implemented in every class like int, float etc

 

Yes it works perfectly indeed, with you Solutions PBeast and LeftRighty i made this :

Code (CSharp):

1.  
2.     public static string ToStringOptimized(float f,int d)
3.     {
4.         string tmpNumber = "";
5.         string Decimal = "F" + d.ToString ();
6.         if (f > 1000) {
7.             tmpNumber = (f / 1000).ToString (Decimal) + " Mega";
8.         } else if (f > 1000000) {
9.             tmpNumber = (f / 1000000).ToString (Decimal) + " Giga";
10.         } else if (f > 1000000000) {
11.             tmpNumber = (f / 1000000000).ToString (Decimal) + " Tera";
12.         } else {
13.             tmpNumber = f.ToString ("F0");
14.         }
15.        
16.         return tmpNumber;
17.     }
18.     }

I was in fact missing the "return" and "string method" stuff, i'm just beginning at coding^^.

And i'm now using this in a public static states so i can use it all along my scripts, thanks a lot again, i can now display my damages without insanely long numbers haha (i'm doing a little HeroesClicker/TapTitan project for fun)
