The developer walks through instance rendering for weed meshes, creating textured 3D models, weed lifecycle management (growth, density caps, serialization), weeding tools with different area effects, plant health impact from nearby weeds, compost modifiers that affect weed growth speed, and an aggressive invasive weed species that spreads like an infection and requires consistent weeding or weed killer to eradicate. Settings are externalized to a text file for easy balancing without code changes. ## Full article daily.dev links to this article rather than hosting it.
