{{this is a|console command|name=impulse}}
__NOTOC__
It is a generic client-side [[console command]] that is used to send commands to the [[server]] without modifying the [[usercmd]].

The advantage is that new commands can be added without compatibility-breaking networking changes; the disadvantage is that only one impulse can be sent at a time, and that the commands themselves are non-descriptive.

{{confirm|Impulses are not [[prediction|predicted]].}}

Syntax:<pre>impulse NUMBER</pre>

Impulse commands are generally used for development functions and/or cheats, and almost all require {{ent|sv_cheats}}. See <code>[[CBasePlayer]]::ImpulseCommands()</code>, <code>CBasePlayer::CheatImpulseCommands()</code> and <code>CHL2_Player::CheatImpulseCommands()</code>.

==Impulses==
===General===
These are available in most or all Source games.

|-
|-
!81
|
| Gives the player a {{ent|weapon_cubemap}}, used to test [[cubemaps]].
|-
!100

!102

| Spawns a [[VPhysics]] human skull (<code>models\Gibs\AGIBS.mdl</code>) from inside the player (might land behind you). Meant to spawn a "random" gib and seems to be used in [[Half-Life: Source]].
|-
!103

|-
!106
|
| Prints the class, [[targetname]] and [[model]] of the entity under the crosshairs to the console.
|-
!107

|-
!195, 196, 197
| Nonfunctional
| Supposed to show the shortest path to the nearest air, large, and human nodes respectively.
|-
!200
|
| Plays the current [[viewmodel]]'s holster animation. Doesn't actually prevent attacking. (The current weapon just won't be visible.) Not all weapons have holstering sequences.
|-
!201
| Not a cheat

Sound files must be Source-compatible [[WAV]] files under 128KB (512KB in newer engines). Jingles function using the same system as sprays, and are subject to the same anti-spam cooldown. {{note|This works with the SDK codebase, but games seem to typically disable jingles.}}
