Any way to schedule a series of Jobs in array?

Hi, I have some jobs, which are similar & parameterless. So I want to put them into an array to schedule and then combine the dependency, instead of doing it one by one.

I try this, but the complier complain that:

Spoiler

The type 'Unity.Entities.JobForEachExtensions.IBaseJobForEach' must be a non-nullable value type in order to use it as parameter 'T'

Code (CSharp):

1.  
2.         using Unity.Jobs;
3.         using static Unity.Entities.JobForEachExtensions;
4.  
5.         public IBaseJobForEach[] Jobs = {new xJob(), new yJob()};
6.  
7.         public JobHandle ScheduleJobs()
8.         {
9.             foreach (var job in Jobs)
10.             {
11.                 new SleepConsiderJob().Schedule();
12.             }
13.         }

Any suggestion would be appreciated!

 

Storing a struct in an array typed as an interface will result in a boxing conversion, essentially wrapping it in a reference type. The extension method has no way of knowing that whats in there is actually a value type and the Schedule extension requires a value type.

Set the type of your array to the actual type of the job, not the IJob interface.

 

When i need to combine several jobs (more than 3) i use this:

Code (CSharp):

1.     public static JobHandle CombineDependencies(params JobHandle[] jobs) {
2.       var deps = default(JobHandle);
3.       for (var i = 0; i < jobs.Length; ++i)
4.         deps = JobHandle.CombineDependencies(deps, jobs[i]);
5.       return deps;
6.     }

 

Combinedependencies takes a nativearray<jobhandle>

 

That's right. Forgot about it.

 

Your code works fine! Thanks!
