Question Burst error BC1064, Why float3 is unsupported

Burst error BC1064: Unsupported parameter `Unity.Mathematics.float3` `pivot` in function `DestructionSystem.rotateAroundPoint(Unity.Mathematics.float3 pivot, Unity.Mathematics.quaternion targetRotation, Unity.Mathematics.float3 itemPosition, Unity.Mathematics.quaternion itemRotation, ref Unity.Mathematics.float3 finalPostion, ref Unity.Mathematics.quaternion finalRotation)`: structs cannot be passed to or returned from external functions in burst. To fix this issue, use a reference or pointer.

 

Unity.Mathematics.quaternion is same error, so what is the correct usage of the float3 and quaternion in static method with [BurstCompile]

 

Pass your data by 'ref' or 'in', or use Jobs

 

yeah, it works. But I hope I can use it like 'float', don't need to use 'ref' at all.

 

You don't really lose much if you specify "in" for the struct parameters, just a change from copying the structs to getting a pointer to the value in the stack or a compiler-generated temporary variable when necessary. You don't even need to specify "in" when calling the methods if you don't have other by-value overloads that would be prioritized.
