Physis v0.1.0 — Changelog

🌼 New Feature: Golden Dandelion — Environmental Freeze

A new powerful flora item has been introduced: the Golden Dandelion. When placed, it creates a 10-block radius frozen zone that completely halts all plant growth and propagation within its area of effect.

Freeze Mechanics

• Complete Growth Suppression — All saplings within the frozen zone are prevented from growing into trees, even with Bone Meal.
• Bone Meal Blocked — Bone Meal has no effect on any plant, crop, or sapling inside the frozen area.
• Vegetation Spread Halted — Grass, flowers, bushes, moss, vines, and all other vegetation will no longer spread or propagate within the zone.
• Mod-Driven Expansion Frozen — The mod's own forest expansion, edge growth, and vegetation distribution systems fully respect the frozen zone.

Visual & Audio Feedback

• Placement Effects — When placed near active flora, a spinning particle ring (END_ROD) animates around the 10-block perimeter, accompanied by a beacon deactivation sound.
• Freeze Particles — Snowflake and End Rod particles appear on a random sample of affected plants, indicating the freeze effect. Limited to 15 blocks max to maintain performance.
• Unfreeze Particles — Upon removal, Happy Villager and Composter particles bloom on affected flora, symbolizing the return of growth.
• Sound Design — Subtle beacon sounds play on placement and removal (volume 0.8), providing clear auditory feedback without being intrusive.

Smart Flora Detection

• Intelligent Scanning — The system scans the 10-block radius for actual vegetation before activating effects. Placing the dandelion on barren terrain triggers no visual or audio feedback.
• Tree Validation Integration — Uses the mod's existing TreeValidator system (BFS algorithm) to distinguish real natural trees from player-built wooden structures. Wooden houses will not trigger the effect.
• Self-Exclusion — The Golden Dandelion itself is excluded from flora detection, preventing false positives.

Exceptions (Intentional)

• Leaf Litter — Trees within the frozen zone will continue to drop leaf litter naturally.
• Cherry Petals — Cherry trees will still shed pink petals on the ground beneath them.

These cosmetic drops are preserved to maintain visual atmosphere without affecting gameplay balance.

Technical

• Extracted all Golden Dandelion logic into a dedicated GoldenDandelionHandler.java class for clean code separation.
• Added BoneMealItemMixin to intercept bone meal application at the engine level.
• Added getValidTreeBlocks() to TreeValidator for reusable tree block collection.
• Particle sampling uses Fisher-Yates shuffle for unbiased random selection.
• All area scans run only on placement/removal events — zero per-tick overhead.
