HowTo: NativeText to float ?

Scripting Burst

I’m seeing the following error while trying to parse some floats out of some NativeTexts I’m passing into a job via a NativeHashMap.

C:\GitLab\Unity Projects\sim-studio\SimStudio\Assets\Scripts\Simple Earth 3D\SpawnManager.cs(228,1): Burst error BC1016: The managed function `Unity.Collections.NativeText.ToString(Unity.Collections.NativeText* this)` is not supported

 at SpawnManager.UpdateSatellitePositionsJob.Execute(SpawnManager.UpdateSatellitePositionsJob* this, int index, UnityEngine.Jobs.TransformAccess transform) (at C:\GitLab\Unity Projects\sim-studio\SimStudio\Assets\Scripts\Simple Earth 3D\SpawnManager.cs:228)
 at UnityEngine.Jobs.IJobParallelForTransformExtensions.TransformParallelForLoopStruct`1<SpawnManager.UpdateSatellitePositionsJob>.Execute(ref SpawnManager.UpdateSatellitePositionsJob jobData, System.IntPtr jobData2, System.IntPtr bufferRangePatchData, ref Unity.Jobs.LowLevel.Unsafe.JobRanges ranges, int jobIndex)

While compiling job:
UnityEngine.Jobs.IJobParallelForTransformExtensions+TransformParallelForLoopStruct`1[[SpawnManager+UpdateSatellitePositionsJob, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]], UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null::Execute(SpawnManager+UpdateSatellitePositionsJob&, 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)

Example code of what I’m trying to do

//*** As input to a job
NativeHashMap<NativeText, NativeText> record = new NativeHashMap<NativeText, NativeText>(3, Allocator.TempJob);
record.Add(new NativeText("abc", Allocator.TempJob), new NativeText("123", Allocator.TempJob));
record.Add(new NativeText("bcd", Allocator.TempJob), new NativeText("234", Allocator.TempJob));
record.Add(new NativeText("cde", Allocator.TempJob), new NativeText("345", Allocator.TempJob));


//*** Later inside of a job that's Burst compiled
float x = float.Parse(record[new NativeText("abc", Allocator.TempJob)].ToString());
float y = float.Parse(record[new NativeText("bcd", Allocator.TempJob)].ToString());
float z = float.Parse(record[new NativeText("cde", Allocator.TempJob)].ToString());

Unity.Mathematics.float3 myVector = new Unity.Mathematics.float3(x,y,z);

Question

  • Is it possible to pass a string into a burst compiled job and extract a float value from it? How?

You can easily find the above method by just searching “Parse” in the search box for that package’s documentation. Get into the habit of digging around on the internet a bit.
