Function: guardRender()

function guardRender(
   app, 
   onFail, 
   failures?
): () => void;

Defined in: src/diagnostics/renderGuard.ts:16

Replaces Pixi's render on the ticker with one that survives a throw and reports a renderer that keeps failing. A ticker listener that throws never asks for the next frame, and Stage's per-step guard covers the game's steps, not the renderer's: a render that threw on its first frame froze the canvas in silence while the page went on. A single bad frame is let go; failures in a row are reported once. Returns the uninstall, which puts Pixi's own render back.

Parameters

Parameter	Type	Default value
app	Application	undefined
onFail	(detail, err) => void	undefined
failures	number	30

Returns

() => void
