Question [1.0.0-exp.8] Breaking changes questions

1) Both World.GetExistingSystem<GhostPredictionSystemGroup>().PredictingTick and
World.GetExistingSystem<ServerSimulationSystemGroup>().ServerTick change to SystemAPI.GetSingleton<NetworkTime>().ServerTick?

2) World.GetExistingSystem<GhostPredictionSystemGroup>().Time.DeltaTime change to SystemAPI.Time.DeltaTime?

 

Hello @optimise,

Very good question !

Can you please share your manifest.json because i am struggling to migrated from 0.51 to 1.0 with all the dependencies.. ?

 

That is what we used for the migration of our current netcode project and it worked as expected.

Also don't forget to remove the checks to prediction and instead use the `WithAll(typeof(Simulate)`, which is a lot more pleasant than before.

@Ali_Bakkal You just need to upgrade everything to 1.0, dependencies should be automatically handled. With what are you exactly struggling?

 

Unity does not offer automatic upgrade, so i change directly the version inside of the manifest.json. And when i put : Entities, replace Hybrid by entites.graphics and Netcode to 1.0, i have dependency errors.. can you please send me a copy of your manifest.json in order to check all my dependencies..

Thanks in advance

 

If you can’t upgrade directly from the package manager it’s probably because you aren’t using the right unity version.

Which unity version are you currently using in the project?

 

I am using Unity 2020.3.30f1, which version should i use then ?
(which is stable to build on Linux, Macos, Android and iOS)

 

If you want to use 1.0.x you need to use 2022.2.x (currently in beta).

otherwise you need to stay on 0.53

 

(if you use netcode you currently can’t build for any platform, it’s a known issue and they are working on it)

 

Ok Thank you @Occuros for your help !

 

Not really understand what u mean. Can u show me an example?

 

Do u mean when u the system is at PredictedSimulationSystemGroup and you are updating owner predicted/predicted ghost, you need to put WithAll<Simulate>() into the ghost? Btw then do we still need to call predictedghost.ShouldPredict() from PredictedGhostComponent just like at 0.51?

 

There is also now a different way how you can handle inputs.

No more Tick is required, and events are supported (so you can be sure that jump button gets processed):

Code (CSharp):

1. public struct PlayerInput : IInputComponentData
2. {
3.     public int Horizontal;
4.     public int Vertical;
5.     public InputEvent Jump;
6. }

So it is no more a buffer, but you get the correct input for the frame you are processing in the prediction.

The documentation is a little problematic as it still uses the previous way in the `GettingStarted` section, and in the `Command Stream` section, it still uses the deprecated `GenerateAuthoringComponent` attribute.

But if you use the bakers instead the `Command Stream` section should be up to date (I think correct @CMarastoni ?)


At least we managed to get our project fully up and running in the editor.

 

I see but currently I have a lot of systems at PredictedSimulationSystemGroup still using predictedGhostComponent.ShouldPredicted(). Can I still keep it first until I have time to upgrade to this new way? Btw if I understand correctly, seems like there's typo for code snippet. I guess new way should like that right?

Code (csharp):

1.  
2. Entities.WithAll<Simulate>().Foreach(Entity ent, ref MyCompo compo)=>
3. {
4.  
5. })
6.  

 

For my old Command Buffer way I put

One more question want to confirm about this. Will this WithAll<Simulate>() without if PredictedSimulationSystemGroup.ShouldPredict(component) check still working properly if it's query the child ghost entity of owner predicted/predicted ghost? This child ghost entity is part of the owner predicted/predicted ghost that is child of it that u can fold/unfold at Entities Hierarchy window. From what I see child ghost entity also have Simulate tag component.
