"""Compare Horizon's light engine with the vanilla 26.3 server.
|
|
|
|
Builds a scene of slabs, stairs, snow layers, trapdoors, lanterns, glass,
|
|
leaves, water and glowstone in a fresh vanilla world, lets the vanilla light
|
|
engine settle, stops the server so the SkyLight/BlockLight arrays are saved,
|
|
then relights every saved chunk with `examples/probe/light_parity` and requires every
|
|
value to agree. The example also replays block edits through the incremental
|
|
`light::relight` and checks them against a full relight.
