BuoyancyDebugSystem

Remarks

The half of the sixth verb that was owed. The lines were written and tested and the verb was registered, and nothing joined them: no host copied WaterDebug.ShowBuoyancy into Enabled and no host called Draw. So the toggle set a bool that nothing consumed, in the editor's Water menu as well as the console.

⚠ Show is a delegate because the flag is in an assembly this one must not reference. WaterDebug lives in Vixen.Rendering.Water, and § D1 puts the physics join in its own assembly precisely so that nothing linking Jolt is linked by a renderer — reaching for the flag from here would drag a graphics device into the path a dedicated server runs. So a host that has both writes the join once, at registration: Show = () => WaterDebug.ShowBuoyancy. Left null, Draw's own Enabled is honoured, which is what a headless build or a test drives it with.

⚠ Read once a frame rather than subscribed to. The flag is a static a console verb writes at any moment; a system that cached it would draw one frame behind every toggle, and the frame somebody is looking at when they press the key is the one that matters.

⚠ PreRender, and both neighbours decide it. TransformSystem writes the WorldTransform the pontoons are placed from in LateUpdate, so anything earlier draws the spheres where the body was; and the accumulator is drained during Render and aged after it, so anything later draws into a frame that has already been recorded. Neither failure says anything — the picture is a lag or an empty screen.

Fields and properties (4)

• public Func<bool>? Show

  Where the host's water.showBuoyancy is, or null to drive Draw directly.

• public BuoyancyDebugDraw Draw

  The lines themselves, so a host can change the arrow scale.

• public int Frames

  How many frames this has drawn into the accumulator.

• public SystemAccess Access

Methods (3)

• public BuoyancyDebugSystem(BuoyancySystem buoyancy, DebugDraw into)

  The frame that joins water.showBuoyancy to BuoyancyDebugDraw.

• public override JobHandle Update(in SystemContext context, JobHandle dependency)

  Runs the system.

• public void Step(World world)

  Copies the flag across and draws one frame's worth.
