classRenderPassInspectorLayer

@codexo/exojs/debug / debug / stable

Debug layer that lists every RenderNode with an active filter chain each frame. Renders a compact text panel with per-drawable rows showing the filter sequence, bounding-box dimensions, and mask/cache status. Use during development to answer: - "Is my filter actually attached?" → it appears in the list - "Why does my frame have N render passes?" → see total pass count - "Is this drawable being re-rendered or cached?" → `[cached]` flag For deep per-pass inspection (intermediate render-target contents, GLSL/WGSL source, uniform values), use Spector.js or Chrome DevTools' WebGPU panel - the engine emits debug-group labels around filter and mesh-custom-shader passes so those tools show meaningful pass names.

Constructors1
new(app: ApplicationTop-level engine instance. Owns the canvas, render backend, scene-stack controller, the core systems (input, interaction, audio, coroutines, tweens, animations…): RenderPassInspectorLayer
Methods6
destroy(): void
Release any scene-graph nodes or resources owned by this layer. Called by DebugOverlay.destroy. The base implementation is a no-op; subclasses override to tear down their Container subtrees.
pipelineRows(): RenderPipelineRowOne row of a RenderPipeline listing produced by RenderPassInspectorLayer.describePipeline. Identity is the pass object; `label` is display-only (no names are r…[]
Depth-tagged rows for the inspected pipeline (empty if none is set).
render(backend: RenderBackend): void
Submit the panel's Container subtree to the backend for drawing.
setPipeline(pipeline: RenderPipelineAn ordered list of RenderPass steps, played once per frame against a RenderingContext. A `RenderPipeline` is **itself a `RenderPass`**, so pipelines nest freel… | null): this
Set a RenderPipeline to list beneath the filter chains, or null to clear it.
update(_delta: SecondsA length of time in seconds. The unit every duration in the public API is expressed in - frame deltas, the fixed step, elapsed totals, timer limits. It is a `n…): void
Walk the scene graph and collect filter-chain entries for every RenderNode with at least one filter. Replaces the previous frame's snapshot. The current snapshot is exposed via entries for tests and external consumers.
describePipeline(pipeline: RenderPipelineAn ordered list of RenderPass steps, played once per frame against a RenderingContext. A `RenderPipeline` is **itself a `RenderPass`**, so pipelines nest freel…): RenderPipelineRowOne row of a RenderPipeline listing produced by RenderPassInspectorLayer.describePipeline. Identity is the pass object; `label` is display-only (no names are r…[]
Flatten a RenderPipeline into depth-tagged rows, recursing into nested pipelines. Pure and app-independent: identity is the pass object and label is display-only - no names are required.
Properties5
visible: boolean
entries: readonly RenderPassInspectorEntrySnapshot of one drawable's filter chain at the moment the inspector collected it. Held by reference inside RenderPassInspectorLayer for the duration of one fra…[]
Read-only snapshot of the entries collected on the most recent update call. Useful for tests and for external tooling that wants to render its own visualisation rather than use the built-in panel.
pipeline: RenderPipelineAn ordered list of RenderPass steps, played once per frame against a RenderingContext. A `RenderPipeline` is **itself a `RenderPass`**, so pipelines nest freel… | null
The pipeline currently being inspected, or null.
totalPasses: number
Total pass count across all collected entries.
viewMode: DebugLayerViewModeDetermines the coordinate space a DebugLayer renders into. `'screen'` uses the overlay's pixel-space view; `'world'` uses the scene's current world-space view…
Whether this layer renders in the scene's world-space view or in a screen-space (canvas-pixel) view. Defaults to 'screen'. Subclasses override to return 'world' when rendering at actual scene positions.
