Nevertheless I had nothing to do this Sunday afternoon and got around implementing a particle engine.
I like programming particle engines. A particle engine was my first and most major contribution to The Mana World. My first thought was porting the TMW particle engine to Javascript as-is (just using JSON instead of XML for particle definitions), but then I decided that a different architecture is much more suitable for JS. Instead of defining the physical properties of each particle type in an XML file (or rather JSON), I decided to implement the physical behavior of each type with a function.
