[v0.0.7] Implement Grass System

[jacuzzicoding]

Description

Implement a grass system that serves as both a visual enhancement to the world and a food source for herbivore NPCs like deer. The grass should grow over time, be affected by environmental factors, and be consumed by animals.

Requirements

• Create GrassComponent and GrassSystem for handling grass mechanics
• Implement visual representation of grass (can be simple shapes initially)
• Add growth mechanics tied to time and environmental factors
• Implement interaction with animals (grazing)
• Create regrowth mechanics after being eaten
• Add seasonal effects on grass growth (if applicable)

Technical Details

• New components/systems needed:
  • GrassComponent for individual grass properties
  • GrassSystem for managing growth and interactions
  • Integration with TimeManager for growth cycles
  • Spatial partitioning for efficient grass management
• Performance considerations:
  • Instanced rendering for grass
  • Level-of-detail system for distant grass
  • Culling for off-screen grass

Acceptance Criteria

• Grass spawns naturally in appropriate world areas
• Grass visually represents its growth state
• Grass grows over time based on environmental factors
• Animals can interact with grass (grazing mechanics)
• Grass regrows after being consumed
• Performance remains stable with large amounts of grass
• System is extensible for future plant types
