📖 Overview

Collapsible Game Rules includes interactive UI controls and built-in Game Rule presets, allowing players to configure complex world settings with single-click profiles or intuitive sliders instead of typing raw integer values into text boxes.

🏰 Built-in Presets Matrix

Preset ID	Display Title	Game Rule	Configured Value	Gameplay Impact
builder	🏰 Builder Mode	doDaylightCycle doWeatherCycle doMobSpawning keepInventory mobGriefing doFireTick	false false false true false false	Ideal for creative building: freezes sun/weather, stops mob spawns, disables creepers/fire spread.
fast_play	⚡ Fast Play	randomTickSpeed playersSleepingPercentage keepInventory	10 0 true	Fast-paced survival: accelerates crop growth ($3\times$), allows single-player sleep skipping, keeps inventory.
hardcore	💀 Hardcore Realism	naturalRegeneration doInsomnia playersSleepingPercentage	false true 100	Extreme survival: disables passive health regen (golden apples/potions required), enforces phantom spawns.

🎚️ Interactive Slider Widget (IntegerSliderWidget)

The IntegerSliderWidget replaces raw numeric text fields with draggable sliders for smooth integer adjustments.

Mathematical Normalization Formulas

When setting a slider position from an integer value $v$: $$\text{normalized} = \frac{\text{clamp}(v, \text{min}, \text{max}) - \text{min}}{\text{max} - \text{min}}$$

When computing the resulting integer value from the slider position $p \in [0.0, 1.0]$: $$\text{calculatedInt} = \text{min} + \text{round}\left(p \times (\text{max} - \text{min})\right)$$

🔘 Boolean Toggle Widget (BooleanToggleWidget)

The BooleanToggleWidget provides instant visual feedback for binary rules:

• State: TRUE (ON): Renders ✔ ON in ChatFormatting.GREEN over a green background fill (0x4400FF00).
• State: FALSE (OFF): Renders ✖ OFF in ChatFormatting.RED over a red background fill (0x44FF0000).
• Mouse Press: Single click toggles state and executes the consumer callback onToggle.accept(newState).

┌─────────────────────────┐     ┌─────────────────────────┐
