Particles roots & vine system

Particles Roots & Vine System is a Unity particle-based surface-following system for creating organic crawling effects such as roots, vines, ivy growth, magical trails, spreading energy, insects, sparks, and other particles that move along walls, floors, rocks, and mesh surfaces.

The system controls particle movement so particles can detect nearby colliders, stay close to the surface, and continue moving along it instead of flying freely. It is useful for procedural-looking growth effects, wall-crawling particles, fantasy magic, nature effects, horror environments, and sci-fi surface energy effects.

The script supports corner following, forward blocker detection, surface offset control, layer filtering, and original particle speed preservation. You can still use standard Particle System modules such as Noise, Color over Lifetime, Size over Lifetime, Trails, and Texture Sheet Animation to customize the final look.

Features:

• Particles move along nearby surfaces
• Works with Unity Particle System
• Supports walls, floors, rocks, columns, and mesh colliders
• Corner and surface normal following
• Anti-penetration blocker check
• Layer mask control for detected surfaces
• Adjustable surface offset and search distance
• Preserves original particle speed
• Can be combined with Particle System Noise
• Useful for roots, vines, ivy, magic, energy, sparks, and crawling effects

Requirements:

Objects that particles should follow must have colliders. For best results, set the Particle System Simulation Space to World.
