Question I cannot add my resolution dropdown to the slot in my inspector.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Audio;
5. using UnityEngine.UI;
6.  
7. public class SettingsMenu : MonoBehaviour
8. {
9.     public AudioMixer audioMixer;
10.  
11.     public Dropdown resolutionDropdown;
12.  
13.     Resolution[] resolutions;
14.    
15.     void Start()
16.     {
17.         resolutions = Screen.resolutions;
18.  
19.         resolutionDropdown.ClearOptions();
20.  
21.         List<string> options = new List<string>();
22.  
23.         for (int i = 0; 1 < resolutions.Length; i++)
24.         {
25.             string option = resolutions[i].width + "x" + resolutions[i].height;
26.             options.Add(option);
27.         }
28.  
29.         resolutionDropdown.AddOptions(options);
30.     }
31.  
32.  
33.     public void SetVolume (float volume)
34.     {
35.         audioMixer.SetFloat("Volume", volume);
36.     }
37. So up above I have
38.  
39.     public void SetQuality (int qualityIndex)
40.     {
41.         QualitySettings.SetQualityLevel(qualityIndex);
42.     }
43.  
44.     public void SetFullScreen (bool isFullScreen)
45.     {
46.         Screen.fullScreen = isFullScreen;
47.     }
48. }
49.  

Up above I have: public Dropdown resolutionDropdown; and thats where I would throw in my actual drop down UI but for some reason it won't let me, I am following a tutorial and the person doing it did it without any trouble and I cannot seem to find anything wrong. This is for a options menu BTW, ty in advance!

 

I don't see anything immediately wrong with your class here, are you sure you're trying to drag and drop the game object which has the Dropdown component on it?

 

Im pretty sure I am, the dropdown is a text mesh pro dropdown but I wouldn't think that would be an issue. When I created the object I just went to UI then Dropdown-text mesh pro and after I set it up I couldn't drag it into my resolution dropdown.

 

Try to replace this:

Code (CSharp):

1. public Dropdown resolutionDropdown;

with this:

Code (CSharp):

1. public TMP_Dropdown resolutionDropdown;

Also I think you will need at the top of your file the

Code (CSharp):

1. using TMPro;

 

This works for me:

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3. using UnityEngine.Audio;
4. using TMPro;
5.  
6. public class SettingsMenu : MonoBehaviour
7. {
8.     public AudioMixer audioMixer;
9.     public TMP_Dropdown resolutionDropdown;
10.     Resolution[] resolutions;
11.  
12.     void Start()
13.     {
14.         resolutions = Screen.resolutions;
15.         resolutionDropdown.ClearOptions();
16.         List<string> options = new List<string>();
17.         for (int i = 0; 1 < resolutions.Length; i++)
18.         {
19.             string option = resolutions[i].width + "x" + resolutions[i].height;
20.             options.Add(option);
21.         }
22.         resolutionDropdown.AddOptions(options);
23.     }
24.     public void SetVolume (float volume)
25.     {
26.         audioMixer.SetFloat("Volume", volume);
27.     }
28.     public void SetQuality (int qualityIndex)
29.     {
30.         QualitySettings.SetQualityLevel(qualityIndex);
31.     }
32.     public void SetFullScreen (bool isFullScreen)
33.     {
34.         Screen.fullScreen = isFullScreen;
35.     }
36. }

 

Got it to work!! TY!!!

 

Index was outside the bounds of the array.
Hmm just got this error after trying to press play.

 

Code (CSharp):

1. for (int i = 0; 1 < resolutions.Length; i++)

1 <

should be

i <

 

Perfect it worked!! Thanks again!!
