Core rules
- Rendering and simulation distances are separate concepts.
- Only sufficiently loaded chunks run all game ticks.
- Portals, spawn regions and commands can affect chunk loading.
Edition and version notes
The core concept exists in the current game, but exact timings, update order, available recipes, commands and edge cases can differ between Java and Bedrock or change between releases. Use the versioned data pages for identifiers and the Java-vs-Bedrock guides for known edition differences.
