Passing array into a Job from external source

Hi

I have a class running a variety of jobs, and I want to pass an array of floats into this class from an external class so that one of the Jobs can access it.

Currently I have

In Job handling class

public NativeList<float>Values

And initialised

Values = new NativeList<float>(0, Allocator.Persistent);



On struct : IJobParallelFor

[ReadOnly] public NativeList<float>JobValues


In struct Constructor

JobValues = Values



External class

* parentClass.Values = anArray.ToNativeList<float>(Allocator.Persistent);

And then run the jobs on parent class



Receiving error
A Native Collection has not been disposed, resulting in a memory leak. Allocated from: { refers to the * line above }

I am confused as I thought persistent allocation of native objects did not require disposal.
If they do, I am not sure where to Dispose() in this stack?

Is this even the right way to pass variables into a Job from a third party?


Thanks for any tips.

 

You still need to dispose them eventually when they are no longer needed. For example:

Code (CSharp):

1. void OnEnable()
2. {
3.     Values = new NativeList<float>(0, Allocator.Persistent);
4. }

Code (CSharp):

1. void OnDisable()
2. {
3.     Values.Dispose();
4. }

 

Right however keep in mind that a line like this

will replace the old native array without disposing it. If the native list is created outside, you shouldn't manually create another NativeList

 

I think this was the issue. I was creating a new NativeArray and assigning from external source. I should just modify the single original nativearray and let it be disposed once.
