How to use the JPCT to achieve smoke,explosions,fountains ,fire and other special effects? :'(
One way is to use a particle system. jPCT itself doesn't include one but there are some basic implementations in various projects of mine. Have a look at the sources linked to in this thread: http://www.jpct.net/forum2/index.php/topic,2784.0.html (http://www.jpct.net/forum2/index.php/topic,2784.0.html)
Alien Runner as well as the An3DBenchXL contain a simple particle system. Maybe that helps to get you started.
