ludic/examples/events/mod_events.ludic
Orkuncakilkaya bf36bc8a8f refactor(runtime,packages,examples): named constants, package enums, idiom sweep
- runtime: HEADLESS_FRAME_PATH, STICK_DEADZONE / STICK_LEFT_X/Y, key and
  byte codes as char literals throughout (`k == 'w'`, `fill(rt_map, ' ', …)`)
- ludic.gameplay/stats: drop the duplicate `stat_field` (it answered "atk"
  for every build stat); Stats.base uses stats_field_name
- ludic.shooter: compare aim modes and fire patterns with AimMode.* and
  WeaponPattern.* instead of raw ints; STICK_RIGHT_X/Y
- ludic.npcai: DecisionMade / brain_set_state use AiState.*
- examples/games/menu.ludic uses Font.load / Ui.* with FONT_PATH and
  BACKDROP named; strings.ludic header says what it prints
- whole tree: `x = x + 1` → `x += 1` (single-term right-hand sides only),
  `0 - x` → `-x`, ASCII codes → char literals; every .ludic and every
  ```ludic fence reformatted with the fixed formatter (whitespace only)

# mod_events.ludic — the event bus with two listeners on one event, driven from
# Ludic (replaces the former tests/mod_c/mod.c foreign-mod host). A public event
# `Damage` has two @On listeners: one prints the amount, one accumulates a total.
# Emitting it twice runs both listeners each time. Prints 10 / 32 / 42.
program ModEvents {
var total: int = 0
event Damage { amount: int = 0 }
@On(Damage) handler Native { print(amount) } # prints each hit
@On(Damage) handler Accum { total += amount } # sums them
entry {
emit Damage(amount: 10) # Native prints 10
emit Damage(amount: 32) # Native prints 32
print(total) # 42
}
}
