Custom Processor throwing error.

I have simple Vector3 processor like this :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. #if UNITY_EDITOR
6. using UnityEditor;
7. #endif
8.  
9. using UnityEngine.InputSystem;
10.  
11. #if UNITY_EDITOR
12. [InitializeOnLoad]
13. #endif
14.  
15. public class InputProcessorRotate : InputProcessor<Vector3>
16. {
17. #if UNITY_EDITOR
18.     static InputProcessorRotate()
19.     {
20.         Initialize();
21.     }
22. #endif
23.  
24.     [RuntimeInitializeOnLoadMethod]
25.     static void Initialize()
26.     {
27.         InputSystem.RegisterProcessor<InputProcessorRotate>();
28.     }
29.  
30.     public Vector3 axis;
31.     public float angle;
32.  
33.     public override Vector3 Process(Vector3 input, InputControl control)
34.     {
35.         var rotation = Quaternion.AngleAxis(angle, axis);
36.         return rotation * input;
37.     }
38.  
39.     //...
40. }

It read correctly in the processor list in Input Asset Window but on adding it to list , throws following exception

Code (CSharp):

1. ArgumentException: Don't know how to convert PrimitiveValue to 'Object'
2. Parameter name: type
3. UnityEngine.InputSystem.Utilities.PrimitiveValue.ConvertTo (System.TypeCode type) (at Library/PackageCache/com.unity.inputsystem@1.0.0-preview.7/InputSystem/Utilities/PrimitiveValue.cs:227)

So i went through the built in processors and it seems there is no out of box support for drawing default serialized unity types.In my case Vector3 property is the issue.

Would be great if we could have better auto handling of those properties for inspector in future.

 

Did you find a solution to this? I'm having the same issue with a Vector2.

 

Sort of. You can write custom inspector for your processor. as explained in the docs : https://docs.unity3d.com/Packages/c...ual/Processors.html#writing-custom-processors

You need to do manually draw Vector2/Vector3 GUI field using relevant API. In your case you can use https://docs.unity3d.com/ScriptReference/EditorGUILayout.Vector2Field.html

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.InputSystem.Editor;
3. using UnityEditor;
4.  
5. public class InputProcessorRotateEditor : InputParameterEditor<InputProcessorRotate>
6. {
7.     public override void OnGUI()
8.     {
9.         var axis = new Vector3(target.x, target.y, target.z);
10.         axis = EditorGUILayout.Vector3Field("Axis", axis);
11.         target.x = axis.x;
12.         target.y = axis.y;
13.         target.z = axis.z;
14.     }
15. }
16.  

 

Hi, I tried your fix but doesn't do fix the issue for me. Did you change something in your processor code to make it work ? fields x, y ,z are not here on your first message. would you mind sharing the all code ?

 

I have also just run into this problem. I do not have a solution yet.
