Deallocate native array - multiple jobs

I've the following case:

I create a RaycastCommand job and I wan't to use the result in multiple other jobs.
After all jobs have finished the NativeArray's should be dealocated by the jobs.

The thing is, I don't want to call jobHandle.Complete() to wait for all jobs and to dealocate the native arrays manually.

Is there a way to use DeallocateOnJobCompletion then all jobs have been finished?

The workaround would be to create a RaycastCommandJob and therefore NativeArrays of commands and results for each job which works with the RaycastCommand...

Code snipped:

Code (CSharp):

1.  
2.  
3.     struct JobA : IJob {
4.         [DeallocateOnJobCompletion] [ReadOnly] public NativeArray<RaycastCommand> RaycastCommands;
5.         [DeallocateOnJobCompletion] [ReadOnly] public NativeArray<RaycastHit> RaycastHits;
6.  
7.         public void Execute() {
8.             // do something
9.         }
10.     }
11.  
12.     struct JobB : IJob {
13.         [DeallocateOnJobCompletion] [ReadOnly] public NativeArray<RaycastCommand> RaycastCommands;
14.         [DeallocateOnJobCompletion] [ReadOnly] public NativeArray<RaycastHit> RaycastHits;
15.  
16.         public void Execute() {
17.             // do something
18.         }
19.     }
20.  
21. protected override JobHandle OnUpdate(JobHandle inputDeps) {
22.         if (!Input.GetMouseButtonDown(0)) {
23.             return inputDeps;
24.         }
25.  
26.         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
27.         NativeArray<RaycastCommand> raycastCommands = new NativeArray<RaycastCommand>(1, Allocator.TempJob);
28.         NativeArray<RaycastHit> raycastHits = new NativeArray<RaycastHit>(1, Allocator.TempJob);
29.         raycastCommands[0] = new RaycastCommand(ray.origin, ray.direction, maxHits: 1);
30.         inputDeps = RaycastCommand.ScheduleBatch(raycastCommands, raycastHits, 1, inputDeps);
31.      
32.         var jobA = new JobA { RaycastCommands = raycastCommands, RaycastHits = raycastHits };
33.         var jobB = new JobB { RaycastCommands = raycastCommands, RaycastHits = raycastHits };
34.         inputDeps = jobA.Schedule(inputDeps);
35.         inputDeps = jobB.Schedule(inputDeps);
36.         return inputDeps;
37.     }

 

I'm not sure if this would be the best idea... but you could create a job that does nothing except deallocate those arrays. Combine all your other jobs in to one job handle and pass that do this job as its dependency.

 

Sometimes it's so simple...

Thank you

 

You could try [DeallocateOnJobCompletion] as a clarification like:

Code (CSharp):

1. public struct MyJob : IJob
2. {
3.     [DeallocateOnJobCompletion]
4.     public NativeArray<byte> data;
5.     {...}
6. }

But there is an issue here saying this may not work sometimes...
