# SETech scene-entity schema for JSON generation
# Emit each entity as: { "type": "<TypeName>", "members": { ... } }
# Scalars ( float / int / bool / enum ) are JSON STRINGS, e.g. "1.5", "true", "Point".
# Nested types ( colors, vectors, transforms ) are { "type":..., "members": {...} } objects.
# Text after // is an explanatory comment, not part of the JSON.
# 'script API' lines list the methods AngelScript behaviors can call on that type's
# handles; every listed reflected member is also a direct script property ( owner.m_Xxx ).

## Audio: sound effects and music ( SESynthSceneEntity )
# There are no audio assets. Every sound is synthesized at runtime, so a
# generated scene can have complete audio without shipping a single file.
#
# SOUND EFFECTS - add one entity named "Sfx":
#   { "type": "SESynthSceneEntity", "members": {
#     "m_strEntityName": "Sfx", "m_bGenerateSong": "False", "m_fVolume": "0.7" } }
#   Resolve instrument names ONCE in OnInit, then trigger by index - a game
#   fires effects on every collision and keypress, so the trigger path must
#   not carry a name:
#     SESynthSceneEntity@ sfx; int fxZap = -1;
#     void OnInit() {
#       @sfx = cast<SESynthSceneEntity>(gWorld.FindEntityByName("Sfx"));
#       if (sfx !is null) fxZap = sfx.FindInstrument("Zap");
#     }
#     // at the event:  if (sfx !is null) sfx.PlayEffect(fxZap, 64, 0.8f);
#   PlayEffect takes ( instrumentIndex, midiNote, velocity 0..1 ) and needs no
#   stop call - effect instruments release themselves. Vary the midi note to
#   make repeated events sound different rather than adding instruments:
#   pitch by row, by lane, by combo count.
#   Effect instruments:  Beep Laser Zap Explosion Coin Thud Whoosh
#   Musical instruments: Lead Bass Pad Pluck Bell Harpsichord Flute Strings
#                        Kick Snare Hat
#   Typical mapping: shoot=Laser, hit/break=Zap, pickup/goal=Coin, jump=Beep,
#   land/impact=Thud, death=Explosion, dash/strafe=Whoosh.
#
# MUSIC - add a second entity named "Music" that composes from a seed:
#   { "type": "SESynthSceneEntity", "members": {
#     "m_strEntityName": "Music", "m_strSongFile": "Database/Synth/<name>.xml",
#     "m_bGenerateSong": "True", "m_iSeed": "1234", "m_fTempoBPM": "120",
#     "m_iBars": "8", "m_Scale": "NaturalMinor", "m_iRootNote": "57",
#     "m_bAutoPlay": "True", "m_fVolume": "0.5" } }
#   Leave SongFile EMPTY for a generated soundtrack: the same seed always
#   yields the same song, so naming a file only writes a copy that then
#   shadows the seed. Name one only for a hand-authored song. Scales:
#   Major NaturalMinor
#   Dorian Phrygian Mixolydian PentatonicMinor. Minor scales and a faster
#   tempo read as tense or driving; Major and a slower tempo read as calm.
#   Scripts drive it with PlaySong StopSong PauseSong ResumeSong, and SetTempo
#   ( a multiplier, so raise it as the game speeds up ).
#   Set an authored SongFile with GenerateSong False to play a fixed song
#   instead; a named song file is never overwritten by generation.

## World gameplay properties ( SESceneWorld )
# Set via a top-level "world" key next to "entities" in a command or scene file:
#   "world": { "members": { "m_strPlayerCameraName": "<camera entity name>" } }
# Scripts reach the live world through the global gWorld.
### SESceneWorld
{ "type": "SESceneWorld", "members": {
  "m_strPlayerCameraName": "<string>"    // gameplay property: SECameraSceneEntity to render from while Playing
} }
// script API ( callable on a SESceneWorld@ handle in AngelScript; reflected members are direct properties ):
//   void AddEntity(SESceneEntity@)  - AddAnEntity
//   SESceneEntity@ FindEntityByName(string)  - find an entity by its object name ( resolve once, not per frame )
//   int GetEntitiesCount()  - number of entities in the world
//   SESceneEntity@ GetEntity(int)  - entity by index
