Hi, do I need to add [BurstCompile] for calculateA() and calculateB(), or is it already covered, because OnUpdate() has already the tag? public partial struct TestSystem : ISystem { [BurstCompile] public void OnUpdate(ref SystemState state) { TestSystem.calculateA(); // Burstcompi…

Regarding your System implementation: [image] When, where, and why to put [BurstCompile], with mild under-the-hood explanation Unless you try really hard, all C# called from bursted code is bursted. (Source: https://discussions.unity.com/t/896228 ) So your OnUpdate method has the BurstCompi…

[image] FaithlessOne: Regarding your Job implementation: Nothing is bursted. You have to put the BurstCompile attribute onto the Execute method. Nope, that’s not required. Rest looks correct. If in doubt what’s compiled and what’s not - use Burst Inspector. If respective jobs / methods are …

[image] FaithlessOne: Regarding your Job implementation: Nothing is bursted. You have to put the BurstCompile attribute onto the Execute method. BurstCompile attributes on classes/structs should be used to help Burst finding the methods to be bursted, they itself do not cause Burst compilation o…

Decent heuristic: If you’re seeing it in the Burst inspector, it’s definitely Burst-compiled. Another one: If you’re using it from a Burst-compiled method, it’s definitely Burst-compiled. (You cannot call managed code from Burst, it simply won’t compile, and you’ll see errors in the console and in …

[image] Samsle: Thanks for that!! I just had to update Rider, but it seems it only works for ISystem, but not IJobEntity. Yeah, the update somehow made it worse. Idk how. Probably going to be fixed eventually. [image] Samsle: So does this mean already that calculateX() is compiled with B…

Thank you for clarifying! :slight_smile:
