Physics in Realtime? Framerate Independent

Hi,

After noticing that some of the physics examples are playing TOO fast, I came across some threads with work arounds for forcing physics to update at Unity's fixed delta time.

Although I'm finding that using the work around, the physics plays back too SLOW and looks like slow motion.

I wanted to ask if there is more recent information on this? or any updates to the Physics packages that address this.

Thanks!!

Code (CSharp):

1. using Unity.Entities;
2.  
3. public class FixedTimeStep : ComponentSystem
4. {
5.     private bool once = false;
6.  
7.     protected override void OnUpdate()
8.     {
9.         if (false == once)
10.         {
11.             FixedRateUtils.EnableFixedRateWithCatchUp(World.GetOrCreateSystem<SimulationSystemGroup>(),
12.             UnityEngine.Time.fixedDeltaTime);
13.             once = true;
14.         }
15.     }
16. }
17.  

 

It might be these error messages that are slowing down the physics with EnableFixedRateWithCatchUp enabled. Im getting thousands of them, anyknow familiar with this?

2. Unity.Entities.ComponentSystem:Update() (at Library/PackageCache/com.unity.entities@0.9.1-preview.15/Unity.Entities/ComponentSystem.cs:108)
3. Unity.Entities.ComponentSystemGroup:UpdateAllSystems() (at Library/PackageCache/com.unity.entities@0.9.1-preview.15/Unity.Entities/ComponentSystemGroup.cs:134)
4. Unity.Entities.ComponentSystemGroup:OnUpdate() (at Library/PackageCache/com.unity.entities@0.9.1-preview.15/Unity.Entities/ComponentSystemGroup.cs:120)
5. Unity.Entities.ComponentSystem:Update() (at Library/PackageCache/com.unity.entities@0.9.1-preview.15/Unity.Entities/ComponentSystem.cs:108)
6. Unity.Entities.DummyDelegateWrapper:TriggerUpdate() (at Library/PackageCache/com.unity.entities@0.9.1-preview.15/Unity.Entities/ScriptBehaviourUpdateOrder.cs:200)

 

I narrowed it down to the MousePickBehaviour.cs script. It doesn't seem to be compatible with the FixedUpdate. Not sure how to fix it though.
