info_particle_system is a point entity available in all Source games since Source 2007. It dispatches and offers some control over a specified particle system.

Keyvalues

Name (targetname) <string>: The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report. 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.
Flag as Weather? (flag_as_weather) <boolean> (in all games since ): 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.
Render in front? (render_in_front) <boolean> (only in ): Hack to allow particles to render in front of everything else.
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 those following it will be ignored.
Tip:Control point 0(1) is the origin of the info_particle_system itself.

Note: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.

snapshot_file (snapshot_file) <string> (only in ): Note:Only CSGO ? Loads file "particles/%s.psf"
// Init from a DMX (.psf) file
CParticleSnapshot::Unserialize
Todo: More info

Start: Tell the particle system to start emitting.
Note:To forcibly restart an effect, you must fire Stop first. Start has no effect if the server thinks the system is already running.

DestroyImmediately (in all games since ) (also in ): Particle system disappears immediately instead of fading out.

StopPlayEndCap (in all games since ): Tells the particle system to stop emitting but also play its End Cap State

Note:This can be useful to fade out particles with long lifetimes, that otherwise wouldn't go away with the normal Stop.
