Feature Tour

A sample of six levels joined by portals, each leaning on a group of features, which doubles as a benchmark when left on its title screen.

What's new

  • Feature Tour, a sample of six levels joined by portals:
    • the garden: materials, sky light, shadows, a glTF model and tweens
    • the workshop: 252 crates, joints, triggers, a mesh collider and reverb
    • the night market: 16 lights, point light shadows, nested prefabs and an additive scene
    • the foundry: about 10,000 particles
    • the puppets: 48 skinned rigs on animator state machines
    • the arcade: 400 scripted squares, a coroutine, events and a save
  • The player, the camera, the HUD and the music carry over from level to level.
  • A benchmark. Left on its title screen for six seconds, Feature Tour starts an autopilot that walks every level along a route. It is what we run with --stats-log before and after an optimisation.

Fixed

  • An event listener now goes away with the entity that owns it.
