One ui text with various numbers

how is it possible to change ui text content (in this case numbers) by clicking on an arrow ui button respectively from 1 till 5? each step it adds 1 value untill it gets for example to 5 ?
thanks.

 

Have an integer as a variable of the monobehaviour. Have two methods, one that increments this number and one the decrements the number. Hook up the events to each button - You cand do this in the editor OnClick property for the button. Have a third method witch sets the text to this number (ToString()). The increment method and decrements method should call this method after they modify the number.

You might consider a slider as a better UI design for something like this though. One slide action as apposed to multiple clicks of multiple buttons.

 

Korno thanks for your help, but i cannot use slider though while i have those 2 arrows, u know. also onclick from arrow ui button already is used by another script. can you please write that code so so generally and i will fulfill the rest as you said by methods and other things. only i need the base form . thanks.

 

You can have multiple Handlers for the OnClick method of a button by the way.

I cant write any code for you as I don't have my dev box with me now. Try yourself first and I will take a look if you struggle.

 

ok man i will start it out right now. will tell you by problems as if it is so. anyway,thanks na?!

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class changeprices : MonoBehaviour
5. {
6.  
7.     public int prices;
8.  
9.  
10.     public void increaseprice()
11.     {
12.        
13.     }
14.  
15.     public void decreaseprice()
16.     {
17.  
18.     }
19.  
20.     void setvalue()
21.     {
22.        
23.     }
24. }

this is up to this point, is it correct, how to increment some integer value?

 

something like this:

Code (CSharp):

1.   public class changeprices : MonoBehaviour
2.     {
3.  
4.         public int prices;
5.  
6.         public UnityEngine.UI.Text text;
7.  
8.         public int max = 5;
9.         public int min = 0;
10.  
11.         public void Start()
12.         {
13.             if (text == null) throw new ArgumentException("text not set ");
14.             if (max < min) throw new ArgumentException("max < min...");
15.             if (max == 0) throw new ArgumentException("max = 0");
16.             // start in the middle;
17.             prices = max / 2;
18.         }
19.  
20.         public void increaseprice()
21.         {
22.             prices = prices == max ? max : prices++;
23.             setvalue();
24.         }
25.  
26.         public void decreaseprice()
27.         {
28.             prices = prices == min ? min: prices--;
29.             setvalue();
30.         }
31.  
32.         void setvalue()
33.         {
34.             text.text = prices.ToString();
35.         }
36.     }

make sure you hook up increaseprice and decreasprice in the editor.

 

The type or namespace name `ArgumentException' could not be found. Are you missing a using directive or an assembly reference?
whats the problem?
