Learn when and how to use PixiJS ParticleContainer to batch thousands of sprites, the prerequisites for texture compatibility and properties masks, and how to verify batching is working.
PixiJS scenes with hundreds of sprites usually stall on draw calls and off-screen work. Group textures, cull with cullArea, and animate with deltaTime.
PixiJS Containers group display objects and define local coordinate spaces. Learn how parent transforms propagate to children, when nesting helps, and how to verify global positions without guesswork.
When to use PixiJS RenderTexture, compare it to alternatives, and see a minimal example that creates, renders, and displays a RenderTexture in a scene.
A decision guide for picking PixiJS container types when rendering thousands of sprites, covering draw‑call batching, interactivity, filter support, and mobile GPU constraints with concrete code patterns and validation steps.
Deeply nested Containers in PixiJS can cause CPU bottlenecks during transform updates. Learn how to balance logical hierarchies with performance using flattening and bitmap caching.
Rendering thousands of sprites in PixiJS can choke performance. Learn when to swap a plain Container for a ParticleContainer, the trade‑offs you’ll face, and a concrete example that keeps FPS high.
Learn how PIXI.settings.RESOLUTION maps logical pixels to device pixels, why a fixed default can blur sprites on retina or waste memory on low‑end phones, and how to cap it per device class.
PixiJS batches sprites that share a texture into a single WebGL draw call — but filters, masks, blend modes, and interleaved textures silently split batches. Here's how batching works, what breaks it, and how to verify it with real draw-call counts.
