[FIXED in Burst 1.0.0 preview 9]Does Burst Compiler support System.Boolean (bool) type ?

I have a job like this :

Code (CSharp):

1. [BurstCompile]
2.     struct CopyUnitHasTarget : IJobProcessComponentDataWithEntity<TargetComponentData>
3.     {
4.         public NativeArray<bool> UnitHasTarget;
5.  
6.         public void Execute(Entity entity, int index,[ReadOnly] ref TargetComponentData targetComponentData)
7.         {
8.             if (targetComponentData.Target.Index > 0)
9.                 UnitHasTarget[index] = true;
10.             else
11.                 UnitHasTarget[index] = false;
12.         }
13.     }

While running, Burst compiler show out a error :

Unexpected exception Burst.Compiler.IL.CompilerException: Error while verifying module: Stored value type does not match pointer operand type!

  store i32 %value, i8* %2, align 1

I suppose that Burst compiler doesn't support bool type , I am using Unity 2019.2.0a9 + Burst 1.0.0.preview4

 

thanks for your reply. How can I update to lastet Burst ? I can not update with Package Manager

 

I am using Unity 2019.2.0a9 and i've upgraded just fine. If not try clearing you cache (delete Library folder)

 

I have to remove both Library + Packages folder, then Install Burst package before install Entities Package. thanks

 

I've upgraded to Burst 1.0.0 preview8 but still got same error

 

Bool is not a blittable type, as can be seen here:
https://docs.microsoft.com/en-us/dotnet/framework/interop/blittable-and-non-blittable-types
The easiest way around this is to use a Bool that's backed by a Byte.
An example can be found here:

Of course you could potentially also use bit-shifting, and store multiple bools into a single data-type

 

Thanks , nice work!

 

Yes It's be fixed!!!

 

In this context, doesn't that mean that we could perform a job on NativeArray<NativeArray<T>>? is NativeArray a managed or unmanaged type?

It doesn't seem to work
