State Transitions — Values & Checks

Assumptions

• Time unit: days. grow() called once per day and increments age by 1.
• Ranges: health, waterLevel, sunExposure ∈ [0,100].
• Seasons: Spring, Summer, Autumn, Winter (affect water usage).
• Clamp health/water/sunExposure to [0,100] after any update.

Season multipliers (water usage)

Season	Multiplier
Spring	0.9
Summer	1.3
Autumn	1.0
Winter	0.8

Overview table (per-state parameters)

Parameter / State	Seed	Vegetative	Mature	Dead
Acceptable age range (days)	0 — 6	7 — 29	30 — 119	≥ 120 (terminal)
Acceptable health range	30 — 100	40 — 100	30 — 100	0
Acceptable water range	40 — 100	25 — 100	30 — 100	0
Acceptable sunExposure range	20 — 100	40 — 100	40 — 100	0
Per-day baseline water usage (units/day)	6	10	8	0
Per-day health gain if minima met (units/day)	+4	+3	+1	0
Min water required for daily growth check	40	30	30	0
Min sunExposure required for daily growth check	20	40	40	0
Transition target	Vegetative	Mature	Dead	(none)
Transition condition (single-tick)	age ≥ 7 AND health ≥ 50 AND water ≥ 50 AND sunExposure ≥ 30	age ≥ 30 AND health ≥ 60 AND water ≥ 40 AND sunExposure ≥ 50	age ≥ 120 OR health ≤ 0	—
On successful transition: water reset	25	40	0	0
On successful transition: health reset/minimum	max(current,50)	max(current,60)	0	0
On successful transition: sunExposure reset	50	60	0	0
Notes	grow(): apply baseline water usage * season multiplier, then if water & sun meet minima add health gain, then check transition	same flow as Seed but with vegetative params	same flow; if transition to Dead set all to 0	terminal — no changes

Explicit per-state grow() checks (order of operations)

1. Increment plant.age by 1.
2. Compute water usage: usage = round(baseline_water_usage * season_multiplier).
3. Update water: waterLevel = clamp(waterLevel - usage, 0, 100).
4. If waterLevel >= minWaterForGrowth AND sunExposure >= minSunForGrowth then health = clamp(health + healthGainIfGood, 0, 100).
   • Otherwise health unchanged (no consecutive-day penalties in this simplified model).
5. Check transition conditions for the current state (single-tick checks listed above).
   • If condition met, set new state and apply resets:
     • Seed → Vegetative: water := 25, health := max(health,50), sunExposure := 50
     • Vegetative → Mature: water := 40, health := max(health,60), sunExposure := 60
     • Mature → Dead: health := 0, water := 0, sunExposure := 0
6. No reverse transitions. Dead is terminal.

Quick reference — transition conditions only

From -> To	Condition
Seed -> Vegetative	age ≥ 7 AND health ≥ 50 AND water ≥ 50 AND sunExposure ≥ 30
Vegetative -> Mature	age ≥ 30 AND health ≥ 60 AND water ≥ 40 AND sunExposure ≥ 50
Mature -> Dead	age ≥ 120 OR health ≤ 0
Dead -> (none)	n/a

Example numeric day flow (Seed, Spring)

• baseline water usage = 6; Spring multiplier = 0.9 → usage = round(5.4) = 5
• waterLevel := waterLevel - 5
• if waterLevel ≥ 40 and sunExposure ≥ 20: health += 4
• if age becomes ≥ 7 and health ≥ 50 and waterLevel ≥ 50 and sunExposure ≥ 30 → transition to Vegetative and apply resets
