Editing Particle system (section)

== Developer-friendly particle system tools ==
Particle systems code that can be included in game engines, digital content creation systems, and effects applications can be written from scratch or downloaded. [[Havok (software)|Havok]] provides multiple particle system APIs. Their Havok FX API focuses especially on particle system effects. [[Ageia]] - now a subsidiary of [[Nvidia]] - provides a particle system and other game physics API that is used in many games, including [[Unreal Engine 3]] games. Both [[GameMaker Studio]] and [[Unity (game engine)|Unity]] provide a two-dimensional particle system often used by [[indie art|indie]], hobbyist, or student game developers, though it cannot be imported into other engines. Many other solutions also exist, and particle systems are frequently written from scratch if non-standard effects or behaviors are desired.
