 +====== Particle generator examples ======
 +
 +
 +This articles contains a number of [[ded:​generator|particle generator definition]] examples.
 +
 +(The syntax of these DED examples is not the most exemplary. The Stages in particular should be made more readable.)
 +
 +
 +===== Lost Soul flames =====
 +
 +
 +This generator is used to create the effect of flames for the Lost Soul in jDRP 1.1
 +I have used the Mobj type so that all Lost Souls share the same number of particles.
 +This is important, otherwise Doomsday might slow to a crawl if there are 100 Lost Souls in view and it's trying to spawn eg 200 particles for each. 
 +Furthermore because of the generator limit (256 active generators) I have used the mobj type as Doomsday treats all Lost Souls as THE SAME generator. So 100 Lost Souls == 1 generator when using the mobj type.
 +  ​
 +  Generator {
 +    Mobj = "​SKULL"​
 +    Flags = blend | srcvel | srcdir | static
 +    Center { -1 0 22 }
 +    Speed = .6
 +    Speed rnd = .4
 +    Spawn radius = .8
 +    Spawn age = -1
 +    Max age = -1
 +    Particles = 600
 +    Spawn rate = 1.2
 +    Vector { 0 -2 0}
 +    Vector Rnd = 4
 +  ​
 +    Stage { Type= point Flags= bright Tics= 1 Radius= 12 Bounce= 0 Resistance= .1 Color { 1 .9 .7 .7 } }
 +    Stage { Type= tex07 Flags= bright Force { 0 0 .04 } Tics= 20 Radius= 12 Bounce= 0 Color { 1 .9 .4 .7 } }
 +    Stage { Type= tex07 Flags= bright Force { 0 0 .04 } Tics= 10 Radius= 15 Color { .6 .2 0 .5 } }

 +  }
 +
 +
 +
 +===== Barrel explosion =====
 +
 +
 +This generator is used to create the effects of pieces of broken barrel bouncing
 +around after a barrel is destroyed. It is only one of several generators used for
 +the Barrel Explosion. It is a good example of a generator that uses model particles
 +(note the models are defined elsewhere) and the Alt Start to create two different
 +pieces of barrel using the same generator. This helps to cut down the number of
 +active generators so we don't go over the limit. Notice the empty stage 6, this
 +stops particles in the first group of stages from "​rolling over" into the second
 +group.
 +
 +<​code>​
 +Generator {
 +  State = "​BEXP3"​

 +
 +===== Rain =====
 +
 +
 +This generator is used to create the effect of rain. The rain will be visible in all sectors with flat "​F_SKY1"​ as the ceiling. This generator provides a good example of how flat based generators work. Notice that it makes use of the **density** flag to produce an even distribution of particles in 128x128 blocks rather than per sector. Without this flag particles would "bunch up" in small sectors. Also, notice that we make use of the **distance** property to reduce the amount of rain being rendered to particles that are within 1024 world units of the camera, because this generator produces somewhat heavy rainfall it is not noticeable that the particles in the distance are not being drawn.

 +    Flat = "​F_SKY1"​

 +===== Particle Generators added to jHeretic teleporters =====
 +

 +This is included as an example of tying particle generators to stationary mobjs (as opposed to the lost souls which were mobile). Additionally it also shared in the benefit of reducing the total number of generators used.
