Error with IJobForEach

So, i have this script:

Code (CSharp):

1. namespace Game.Systems {
2.    using Unity.Entities;
3.    using Unity.Burst;
4.    using Game.Data;
5.    using Unity.Jobs;
6.    using UnityEngine;
7.  
8.    public class InputSystem : JobComponentSystem {
9.       [BurstCompile]
10.       struct InputJob : IJobForEach<InputData> {
11.          public float horizontalAxis;
12.          public float verticalAxis;
13.  
14.          public void Execute(ref InputData inputData) {
15.             inputData.Horizontal = horizontalAxis;
16.             inputData.Vertical = verticalAxis;
17.          }
18.       }
19.  
20.       protected override JobHandle OnUpdate(JobHandle inputDeps) {
21.          InputJob job = new InputJob() {
22.             horizontalAxis = Input.GetAxis("Horizontal"),
23.             verticalAxis = Input.GetAxis("Vertical")
24.          };
25.  
26.          return job.Schedule(this, inputDeps);
27.       }
28.    }
29. }

and i'm receiving this error:

when i remove the interface the error goes away, so i don't know what to do.
Is this an error in this interface or am i doing something wrong?

I followed the example in https://docs.unity3d.com/Packages/com.unity.entities@0.0/manual/entity_iteration_job.html

 

InputData needs to be a struct instead of a class. In addition, the InputData struct cannot have unmanaged fields.

 

thank you. i feel ashame of finding github and finding that InputData needs to be IComponentData.

Thank you for reply.

 

No shame in making mistakes mate.
