Question IJobForEach to IJobChunk

Hi All!
I've got a problem with IJobChunk implimentation.
Execute in SpriteSheetAnimation_Job not invoking.
So, my code:

Code (CSharp):

1. public struct SpriteSheetAnimation_Data : IComponentData
2. {
3.     public int currentFrame;
4.     public int frameCount;
5.     public float frameTimer;
6.     public float frameTimerMax;
7.     public Quaternion rotation;
8.     public Vector3 scale;
9.     public Color32 color;
10.     public Vector4 uv;
11.     public Matrix4x4 matrix;
12. }
13. [BurstCompile]
14. public struct SpriteSheetAnimation_Job : IJobChunk
15. {
16.     public ComponentTypeHandle<SpriteSheetAnimation_Data> spriteSheetAnimationData;
17.     public ComponentTypeHandle<Translation> translation;
18.     [ReadOnly]
19.     public float deltaTime;
20.     public void Execute(ArchetypeChunk chunk, int chunkIndex, int firstEntityIndex)
21.     {
22.         var sad = chunk.GetNativeArray(spriteSheetAnimationData);
23.         var t = chunk.GetNativeArray(translation);
24.         for (int i = 0; i < chunk.Count; i++)
25.         {
26.             var isad = sad[i];
27.             var it = t[i];
28.             isad.frameTimer += deltaTime;
29.             while (isad.frameTimer >= isad.frameTimerMax)
30.             {
31.                 isad.frameTimer -= isad.frameTimerMax;
32.                 isad.currentFrame = (isad.currentFrame + 1) % isad.frameCount;
33.                 isad.uv.x = 1f / isad.frameCount;
34.                 isad.uv.y = 1f;
35.                 isad.uv.z = isad.uv.x * isad.currentFrame;
36.                 isad.uv.w = 0f;
37.                 isad.matrix = Matrix4x4.TRS(it.Value, isad.rotation, isad.scale);
38.             }
39.         }
40.     }
41. }
42. public class SpriteSheetAnimation_Animate : JobComponentSystem
43. {
44.     private EntityQuery m_Query;
45.     protected override void OnCreate()
46.     {
47.         m_Query = GetEntityQuery(
48.             ComponentType.ReadWrite<SpriteSheetAnimation_Data>(),
49.             ComponentType.ReadWrite<Translation>());
50.     }
51.     protected override JobHandle OnUpdate(JobHandle inputDeps)
52.     {
53.         var sad = GetComponentTypeHandle<SpriteSheetAnimation_Data>();
54.         var t = GetComponentTypeHandle<Translation>();
55.         var job = new SpriteSheetAnimation_Job
56.         {
57.             spriteSheetAnimationData = sad,
58.             translation = t,
59.             deltaTime = Time.DeltaTime
60.         };
61.         return job.Schedule(m_Query, inputDeps);
62.     }
63. }

This old code with IJobForEach (working fine)

Code (CSharp):

1. public class SpriteSheetAnimation_Animate : JobComponentSystem
2. {
3.  
4.     [BurstCompile]
5.     public struct SpriteSheetAnimation_Job : IJobForEach<SpriteSheetAnimation_Data, Translation>
6.     {
7.         public float deltaTime;
8.  
9.         public void Execute(ref SpriteSheetAnimation_Data spriteSheetAnimationData, ref Translation translation)
10.         {
11.             spriteSheetAnimationData.frameTimer += deltaTime;
12.             while (spriteSheetAnimationData.frameTimer >= spriteSheetAnimationData.frameTimerMax)
13.             {
14.                 spriteSheetAnimationData.frameTimer -= spriteSheetAnimationData.frameTimerMax;
15.                 spriteSheetAnimationData.currentFrame =
16.                     (spriteSheetAnimationData.currentFrame + 1) % spriteSheetAnimationData.frameCount;
17.  
18.                 spriteSheetAnimationData.uv.x = 1f / spriteSheetAnimationData.frameCount;
19.                 spriteSheetAnimationData.uv.y = 1f;
20.                 spriteSheetAnimationData.uv.z = spriteSheetAnimationData.uv.x * spriteSheetAnimationData.currentFrame;
21.                 spriteSheetAnimationData.uv.w = 0f;
22.  
23.                 spriteSheetAnimationData.matrix = Matrix4x4.TRS(translation.Value, spriteSheetAnimationData.rotation, spriteSheetAnimationData.scale);
24.             }
25.         }
26.     }
27.  
28.     protected override JobHandle OnUpdate(JobHandle inputDeps)
29.     {
30.         var job = new SpriteSheetAnimation_Job
31.         {
32.             deltaTime = Time.DeltaTime
33.         };
34.         return job.Schedule(this, inputDeps);
35.     }
36. }

Please, advice me, how can i solve this issue.

 

You're copying the struct value when doing

var isad = sad[i]

, so after doing your computations you need to assign it back the original array

 

Thank you,
