Button with a variable

Hi
I've been programming in Unity recently so I'm a complete newbie.

I would like to create a button that would be responsible for selecting the type of water.

By clicking on the button, the next type would be selected and sent to the HexMapEditor as an int.

How to do it?

example code

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3.  
4.  
5.  
6. public class MltCapBtn : MonoBehaviour
7. {
8.     public int curVal = 0;
9.     public Sprite[] sprites;
10.     public GameObject Logo;
11.     void Awake()
12.     {
13.         curVal = 0;
14.  
15.         // get second function and target object
16.         Button btn = GetComponent<Button>();
17.         var func = btn.onClick.GetFunction(1);
18.         var target = btn.onClick.GetTargetObject(1);
19.  
20.         // set CurVal as parameter
21.         btn.onClick.Function(1) = target.func(curVal);
22.     }
23.  
24.     public void IfClick()
25.     {
26.         curVal++;
27.         if (curVal >= sprites.Length)
28.             curVal = 0;
29.    
30.         Logo.GetComponent<Image>().sprite = sprites[curVal];
31.     }
32. }
33.  

 

Wow, you are working way too hard to set up that button. All that code in your Awake method is not needed. Set up the button's onClick event in the inspector: just drag in the object that you want to handle it (probably whatever has this script on it, or maybe the HexMapEditor), and select the method that should handle the click. If that method takes a numeric parameter, you can type the value you want it to use right there in the inspector too.

 

I would like many time

Func (range values)
SetPlayer (-1 .. 7)
SetWater (-1 .. 2)
SetBrushSize (0 .. 4)
SetElevationLevel (0 .. 5)
SetHouse (0 .. 2)
SetTower (0 .. 2)
SetFarm (0 .. 2)

Etc.. I think, universal method can be usefull, for next function in editor.

 

We do click handler assignments at work, and it's fine to do it that way. But @JoeStrout was still correct in that you're making it way more complicated than it needs to be.

Code (CSharp):

1. // Assign references to these bad boys in the Inspector
2. [SerializeField] private Button btnDoThatThang;
3. [SerializeField] private Button btnDoAnotherThang;
4.  
5. void Awake() {
6.     btnDoThatThang.onClick.AddListener(DoThang(1));
7.     btnDoAnotherThang.onClick.AddListener(DoThang(2));
8. }
9.  
10. private void DoThang(int thangToDo) {
11.     // This is where you do your thang
12. }

 

Its not solve my problem.
