    if I have a JobComponentSystem called BuildPhysicWorld that returns

    Code (CSharp):
    1. return JobHandle.CombineDependencies(FinalJobHandle, inputDeps);
    and then I have a system like

    Code (CSharp):
    1. [UpdateAfter(typeof(BuildPhysicsWorld)), UpdateBefore(typeof(EndFramePhysicsSystem))]
    2. class CharacterEnvironmentCollisionSystem : JobComponentSystem
    would I need this:

    Code (CSharp):
    1. protected override JobHandle OnUpdate(JobHandle inputDeps)
    2. {
    3. inputDeps = JobHandle.CombineDependencies(inputDeps, _buildPhysicsWorldSystem.FinalJobHandle);
    to be sure that the job will be scheduled after the job from BuildPhysicWorld or it should be not necessary? I am not sure if the previous handle is passed somehow inside the next inputdeps and in this case I wouldn't need to do it, but it's just gut filling, the related code is not simple to follow.

    The dependency system should handle it fine without having to manually handle the dependencies yourself (which is the primary point of the system really) as long as you use the system and aren't sharing containers etc outside of it.
