# BurstDiscard attribute
|
|
|
|
If you're running C# code not inside Burst-compiled code, you might want to use managed objects, but not compile these portions of code within Burst. To do this, use the `[BurstDiscard]` attribute on a method:
|
|
|
|
```c#
|
|
[BurstCompile]
|
|
public struct MyJob : IJob
|
|
{
|
|
public void Execute()
|
|
{
|
|
// Only executed when running from a full .NET runtime
|
|
// this method call will be discard when compiling this job with
|
|
// [BurstCompile] attribute
|
|
MethodToDiscard();
|
|
}
|
|
|
|
[BurstDiscard]
|
|
private static void MethodToDiscard(int arg)
|
|
{
|
|
Debug.Log($"This is a test: {arg}");
|
|
}
|
|
}
|
|
```
|
|
>[!NOTE]
|
|
>A method with `[BurstDiscard]` can't have a return value.
|
|
|
|
You can use a `ref` or `out` parameter, which indicates whether the code is running on Burst or managed:
|
|
|
|
```c#
|
|
[BurstDiscard]
|
|
private static void SetIfManaged(ref bool b) => b = false;
|
|
|
|
private static bool IsBurst()
|
|
{
|
|
var b = true;
|
|
SetIfManaged(ref b);
|
|
return b;
|
|
}
|
|
```
