Global Growth Multiplier

⚡ Global Growth Multiplier & Per-Crop Tuning

The Growth Multiplier Engine allows server administrators and players to fine-tune the growth speed of agriculture worldwide or tailor specific growth curves per plant species.

📐 Multiplier Calculation Math & Resolution

The random tick loop intercepts plant growth via BlockStateBaseMixin and GrowthHelper.handleRandomTick:

1. Hierarchy Resolution

1. Dynamic Specific Override ($> 0$): If a specific crop rule is set, it overrides the global multiplier.
2. Frozen / Disabled ($-1$ or Global $0$): Cancels random ticks and offline Continuum deltas completely ($0%$ growth).
3. Inherit Global ($0$): Falls back to the global multiplier $M$.

2. Slowed Growth ($0 < M < 100$)

When $M < 100$, random ticks execute with a probability of $\frac{M}{100}$. For example, at $M = 50$, random growth ticks occur at 50% of vanilla speed.

3. Accelerated Growth ($M > 100$)

When $M > 100$, the engine calculates guaranteed extra random tick runs $E$:

$$E = \left\lfloor \frac{M}{100} \right\rfloor - 1$$

A fractional remainder check with probability $\text{rem} = M \pmod{100}$ awards an additional tick run.

4. Max-Age Early-Break Optimization

During accelerated loops (e.g. $M = 500$, executing 5 runs), handleRandomTick queries AgrarianCropRules.isMaxAge(currentState) after each run. The moment the crop reaches maximum maturity (e.g. Wheat Age 7), the loop terminates immediately, saving unnecessary block evaluations.
