See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Particle System Name (effect_name) <string>

The name of the particle system to spawn. NOT the name of a PCF file!

Start Active? (start_active) <boolean>

Whether the particle system should begin as soon as the entity spawns.

Control Point 1 (cpoint1) to Control Point 63 (cpoint63) <targetname>

Parents a control point to the given entity's origin. If any value is left blank all subsequent values will be ignored.

Tip.pngTip:Control point 0 is the origin of the info_particle_system itself.

Note.pngNote:Because the control point is configured on the client, the entity you specify must exist there. This means that most invisible entities (info_target is an exception, as it has the "Transmit to client" spawnflag) will not work. Your best bet is an info_particle_system, e.g. itself or another one with blank particle name.

Control Point 1's Parent (cpoint1_parent) to Control Point 7's Parent (cpoint7_parent) <integer>

The control point to act as a parent to this one.

Flag as Weather? (flag_as_weather) <boolean> (not in Left 4 Dead series Left 4 Dead series Alien Swarm Portal 2 Counter-Strike: Global Offensive )

Is this particle system going to be used as a weather effect? If so the particle system will not be rendered if the user has disabled weather effects.

snapshot_file (snapshot_file) <string> (only in Counter-Strike: Global Offensive )

Note.pngNote:Only CSGO ? Loads file "particles/%s.psf"
// Init from a DMX (.psf) file
