How to display a struct field in inspector?

Hello!

I have problems while trying to show

Code (csharp):

1. public Rect2 rect;

in inspector,
where Rect2 is a struct:

Code (csharp):

1. [System.Serializable]
2. public struct Rect2
3. {
4.     public bool a;
5.     public int b;
6.     public int c;
7.  
8. }

If I make it a class, then everything works ok:

Code (csharp):

1. [System.Serializable]
2. public class Rect2
3. {
4.     public bool a;
5.     public int b;
6.     public int c;
7. }

Is it possible to show a struct in inspector? Vector3, Rect, Vector2 are all structs and we see them in the inspector, so I am a little bit confused.

Thank you!

 

Not much help but a search would have thrown this up...

That other thread pretty much sums it up. In short, you're out of luck

I seem to be one of the few who thinks being able to serialize custom structs in Unity would be useful. But, I would guess there's a valid technical reason it's not supported.

As for Unity's own struct types, I imagine those are just handled as special cases.

 

For the record, since this is the first Google result that comes up when you search for it: this works now.

You do have to use System.Serializable and make sure your struct members are public, but assuming you do that, it works fine, both for single members and for arrays of them.

 

Pretty old post but I can confirm the above is true. Thanks Joe!

[System.Serializable] right above your declared struct.

 

This still doesn't work for me. I have this:

Code (CSharp):

1. [System.Serializable]
2.     public struct EquippedItem
3.     {
4.         public long id;
5.         public string type;
6.         public string name;
7.         public string equipmentSlot;
8.     }

however, nothing shows in the inspector anyway

 

It will work as long as you have a field of the type EquippedItem exposed to the inspector. Normally via a MonoBehaviour or a ScriptableObject.

 

It should. Please show the MonoBehaviour where you're using this.

(Doh! Sniped by @BoredMormon!)

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.Networking;
4. using UnityEngine.UI;
5. using System.Linq;
6.  
7. public class PartySystem : NetworkBehaviour {
8.  
9.  
10.     [SyncVar]public string partyName = "";
11.     [SyncVar]public int partyLevel = 0;
12.     [SyncVar]public float partyEXP = 0f;
13.     [SyncVar]public int maxMembers = 5;
14.     [SyncVar]public string partyLeader = "";
15.  
16.     [System.Serializable]
17.     public struct EquippedItem
18.     {
19.         public long id;
20.         public string type;
21.         public string name;
22.         public string equipmentSlot;
23.     }

That's my script

 

You need to add public EquippedItem equippedItem; to your variable declarations.

 

thanks

 

Thanks, it worked!

 

Hello Kiwasi! Can we use [System.Serializable] to display variables kept inside a nested structure.....

 

Hai! I had tried [System.Serializable] for simple structure with few variables. But that is not listing up in the Inspector. Could anyone please help!! The structure is kept within monobehaviour .

 

Please post the code (use the Insert Code button, located between the movie filmstrip and the floppy disk icon in the toolbar, to format it correctly). Show both where the struct is declared, and the MonoBehaviour where you are using it.

 

Code (CSharp):

1. using System;
2. using System.Net;
3. using System.Net.Sockets;
4. using System.IO;
5. using System.Runtime.Interopservices;
6. using UnityEngine;
7. using System.Threading;
8. public class NetworkServer:MonoBehaviour
9. {
10. public int portAddress;
11. public int AltHold,AP_Engage;
12. SampleData sData = new SampleData();
13. [System.Serializable]
14. public struct tempControls
15. {
16. public float gama;
17. public float track;
18. }
19. [System.Serializable]
20. public struct Controls
21. {
22. public float gama_ref;
23. public float track_error;
24. public tempcontrols tc;
25. }
26.  

That's my script

 

You would have to have a variable of type 'tempControls' and 'Controls' to see them in the inspector. Maybe just 'Controls' in your case, and you'd see that plus the tempcontrols member.

 

Thank u.Can you explain me with an code snipppet.

 

a code snippet of making a variable?

Code (csharp):

1. public Controls myControls; // wow! :)

try that.

 

Thanks a lot .Finally it worked.
still I have a doubt whether it is mandatory to make my class as Monobehaviour.

 

Hai! I had tried listing up variables of a structure in an inspector.,I succeeded,Thanks a lot methos5k and kiwasi. But i wish to configure a particular set of gameobjects(switches) to do particular animations depending upon structure variables , which i wish to configure through inspector.

Below SwitchTypeis is an enum which tells the switch type. Refer the snap attached, through which switch type will be configured. Similarly, I wish Onswitch,Offswitch,Ontoidleswitch,Offtoidleswitch,OntoOffswitch and OfftoOnswitch to be a structure variable which i wish to list up in the inspector just like enum-dropdown.

Current These variables "Onswitch.... OfftoOnswitch" were declared public keycodes to make the action.

Code (CSharp):

1. switch (SwitchTypis)
2.         {
3.         /*******************************OnOffType****************************************************/
4.         case SwitchType.OnOffType:
5.             if (Input.GetKey (Onswitch))
6.                 //Anim2.Play ("OnOffType");
7.                 anim.SetBool ("OnOffStatus", true);
8.  
9.             if (Input.GetKey (Offswitch))
10.                 //Anim2.Rewind ();
11.                 anim.SetBool ("OnOffStatus", false);
12.             break;
13.             /*********************************PullOnOffType**************************************************/
14.         case SwitchType.PullOnOffType:
15.             if (Input.GetKey (Onswitch))
16.                 //Anim2.Play ("OnOffType");
17.                 anim.SetBool ("OnOffStatus", true);
18.  
19.             if (Input.GetKey (Offswitch))
20.                 //Anim2.Rewind ();
21.                 anim.SetBool ("OnOffStatus", false);
22.             break;
23.             /**********************************OnIdleOffType*************************************************/
24.         case SwitchType.OnIdleOffType:
25.             if (Input.GetKey (Onswitch))
26.                 anim.SetInteger ("Switchpos", 1);
27.  
28.             if (Input.GetKey (Offswitch))
29.                 anim.SetInteger ("Switchpos", 2);
30.  
31.             if (Input.GetKey (Offtoidleswitch))
32.                 anim.SetInteger ("Switchpos", 3);
33.  
34.             if (Input.GetKey (Ontoidleswitch))
35.                 anim.SetInteger ("Switchpos", 5);

37.             if (Input.GetKey (Ontooffswitch))
38.                 anim.SetInteger ("Switchpos", 4);

40.             if (Input.GetKey (Offtoonswitch))
41.                 anim.SetInteger ("Switchpos", 6);

43.             /***********************************PullOnIdleOffType************************************************/
44.         case SwitchType.PullOnIdleOffType:

@adityasreenivas, that is getting well off the topic of this (old) thread. Please start a new thread with your question about animating based on a public enum or integer.

 

Putting all together:
* struct should be marked by [Serializable]
* and it should be declared as public with public fields

 

for the record this will do fine:

Code (CSharp):

1. public class Exmple : MonoBehaviour
2. {
3.         public Data D = new Data{};
4. }
5.  
6. [System.Serializable]
7. public struct Data
8. {
9.     public uint Var;
10. }
