[SOLVED] WithDeallocateOnJobCompletion with multiple ForEach

Hello there
I have a system running two jobs in parallel that use the same chunk array. Something like so:

Code (CSharp):

1. protected override void OnUpdate()
2. {
3.     // ... some logic ...
4.  
5.     // get chunk array
6.     var impact_chunks = impact_group.CreateArchetypeChunkArrayAsync(Allocator.TempJob, out var impact_handle);
7.     Dependency = JobHandle.CombineDependencies(Dependency, impact_handle);
8.  
9.     // schedule first job
10.     var handle1 =
11.     Entities
12.     .WithReadOnly(impact_chunks)
13.     .ForEach(( /* ... */ ) =>
14.     {
15.         // ... some logic here ...
16.     })
17.     .ScheduleParallel(Dependency);
18.  
19.     // schedule second job
20.     var handle2 =
21.     Entities
22.     .WithReadOnly(impact_chunks)
23.     .ForEach(( /* ... */ ) =>
24.     {
25.         // ... some logic here ...
26.     })
27.     .ScheduleParallel(Dependency);
28.  
29.     Dependency = JobHandle.CombineDependencies(handle1, handle2);
30. }

How can I make sure that my chunk array is disposed after both jobs are completed ?
- I cannot use WithDeallocateOnJobCompletion on the first job
- I cannot use WithDeallocateOnJobCompletion on the second job without forcing it to run after the first one (not ideal)
- If I want to use WithDeallocateOnJobCompletion on a third job depending on these two jobs, this new job must use the chunk array in its logic, otherwise this throws an error 5local variable not captured as it is not used)

What is the official recommended solution to this case?

 

Code (CSharp):

1. Dependency = impact_chunks.Dispose(Dependency);

 

Amazing thanks! I don't know how I missed that in the doc
