Job struct being forced into auto layout.

[inner yarrow]

Hello. I am getting this error:

(0,0): Burst error BC1045: Struct `TerraPunk.UnitManagement.PathfinderJob&` with auto layout is not supported

 at Unity.Jobs.IJobExtensions.JobStruct`1<TerraPunk.UnitManagement.PathfinderJob>.Execute(ref TerraPunk.UnitManagement.PathfinderJob data, System.IntPtr additionalPtr, System.IntPtr bufferRangePatchData, ref Unity.Jobs.LowLevel.Unsafe.JobRanges ranges, int jobIndex)


While compiling job:
Unity.Jobs.IJobExtensions+JobStruct`1[[TerraPunk.UnitManagement.PathfinderJob, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]], UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null::Execute(TerraPunk.UnitManagement.PathfinderJob&, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null|System.IntPtr, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089|System.IntPtr, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089|Unity.Jobs.LowLevel.Unsafe.JobRanges&, UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null|System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089)

Why is it being forced into auto layout?

(your link doesn't work)

just fixed it like rn

thanks though lol

[visual talon]

public readonly UnsafeList<(int3 position, float weight)> neighbors;

pretty sure this will be your issue

you can use tuples in burst

but you can't pass them across the mono <-> burst barrier

because they have different layouts

    public struct Pair
    {
        public int3 position;
        public float weight;
        public Pair(int3 position, float weight)
        {
            this.position = position;
            this.weight = weight;
        }
    }```
replacing with that and it compiles fine

ok I'll just make a pair then yea.

let me try

@visual talon thank you, that was causing it. However, I was not passing the tuple between the mono<->burst barrier to my knowledge.

[visual talon]

burst doesn't know that

private NativeList<Node> _openNodes;

is part of your job struct

[inner yarrow]

oh well how would I use a tuple in burst context then?

[visual talon]

just passed within methods

useful for a return from 1 method and using the result etc

really looking forward to struct records when we get them for this case though
