Class RenderManager

Constructor of canvas manager

Canvas rendering context settings

Clears the canvas directly

Clears the canvas content through the layer system.

First checks plugins registered in the dedicated #canvasClearPlugins array, then iterates all layers in ordinal order (0–7) for any additional canvasClear implementations. Plugins registered on multiple layers are only visited once (deduplicated via a visited set).

The first plugin that returns true short-circuits the clear. If no plugin handles it, falls back to canvasClear which respects actualOptions.clear.

Destroying object actions

Generic draw method for drawing stuff on the canvas context

Draws the specified particle in the canvas

Draws stuff using the given plugin, using the given particle

Draws all particles for the current frame via the layer-based rendering pipeline.

Layer order (back to front): 0. BackgroundElement — auto-draw background.element via ctx.drawImage

1. BackgroundDraw — execute background.draw(ctx, delta) callback
2. BackgroundMask — plugin.canvasPaint() for each plugin
3. CanvasSetup — plugin.drawSettingsSetup(ctx, delta) for each plugin
4. PluginContent — plugin.draw(ctx, delta) for each plugin
5. Particles — particles.drawParticles(delta) (core particle rendering)
6. CanvasCleanup — plugin.clearDraw() + plugin.drawSettingsCleanup() for each plugin
7. Foreground — reserved for future overlay/fx

Initializes the canvas element

Initializes the plugins needed by canvas.

Assigns each plugin to ALL layers where it has relevant hooks, not just one primary layer. This enables plugins that implement multiple hooks (canvasPaint→BackgroundMask, drawSettingsSetup→CanvasSetup, drawSettingsCleanup→CanvasCleanup) to participate in all the layers they need.

Hook-independent features (particleFillColor, particleStrokeColor, drawParticle, drawParticleSetup, drawParticleCleanup) are collected into separate arrays for per-particle use during rendering.

Initializes the updaters needed by canvas

Paints the canvas background

Paints the canvas background with an optional base color

Paints an image on the canvas with the given opacity

Sets the canvas rendering context

Sets the canvas rendering context settings

Stops the renderer and clears the canvas

Updates the cached background element from the effective container options
