Protobufs / cs_gameevents.proto

CS2-specific game event protobuf messages. These are temporary entity (TE) events and game events broadcast from the server to clients that are within the relevant PVS or listening for the event type. Identified by the ECsgoGameEvents enum (450–453).

CMsgTEPlayerAnimEvent

Msg TE Player Anim Event MsgTE TEPlayer PlayerAnim AnimEvent player event data

Temporary entity event that triggers a networked animation event on a player's animation graph (jumps, land, crouch transitions, etc.).

Field	Number	Label	Type	Default	Description
player	1	optional	fixed32	16777215	Entity handle (packed as fixed32) of the player triggering the animation event.
event	2	optional	uint32		Animation event ID matching an entry in the player's animation graph.
data	3	optional	int32		Optional integer payload passed to the animation event handler.

CMsgTERadioIcon

Msg TE Radio Icon MsgTE TERadio RadioIcon player

Triggers the radio-icon animation above a player's head when they use a radio command, showing team-mates which player is communicating.

Field	Number	Label	Type	Default	Description
player	1	optional	fixed32	16777215	Entity handle (packed as fixed32) of the player using the radio command.

CMsgTEFireBullets

Msg TE Fire Bullets MsgTE TEFire FireBullets origin angles weapon_id mode seed player inaccuracy recoil_index spread sound_type item_def_index sound_dsp_effect ent_origin num_bullets_remaining attack_type extra player_inair player_scoped tick

Temporary entity event broadcast when a player fires a weapon. Received by all clients within PVS range of the shooter's origin.

The seed field allows clients to reproduce the exact bullet spread using the same PRNG as the server, enabling accurate hit-registration replay in demo parsers.

Field	Number	Label	Type	Default	Description
origin	1	optional	CMsgVector		World-space muzzle position from which the bullet was fired.
angles	2	optional	CMsgQAngle		Aim angles (pitch, yaw) at the moment of fire.
weapon_id	3	optional	uint32	16777215	Item definition index (item_definition_index_t) of the weapon fired. Maps to entries in items_game.txt.
mode	4	optional	uint32		Fire mode – 0 for primary, 1 for secondary/burst.
seed	5	optional	uint32		PRNG seed used to reproduce the bullet spread trajectory.
player	6	optional	fixed32	16777215	Entity handle of the player who fired (packed as fixed32).
inaccuracy	7	optional	float		Inaccuracy value at time of fire, affecting spread cone.
recoil_index	8	optional	float		Recoil accumulator index used for kick-back calculations.
spread	9	optional	float		Weapon spread value at time of fire.
sound_type	10	optional	int32		Sound type index controlling which fire-sound variant plays.
item_def_index	11	optional	uint32		Item definition index of the firing weapon (same as weapon_id for most weapons).
sound_dsp_effect	12	optional	fixed32		DSP (digital signal processing) effect hash applied to the fire sound.
ent_origin	13	optional	CMsgVector		World-space origin of the firing entity (may differ from muzzle origin for some weapon types).
num_bullets_remaining	14	optional	uint32		Clip ammo remaining after this shot.
attack_type	15	optional	uint32		Attack type identifier (0 = primary, other values for special modes).
extra	16	optional	CMsgTEFireBullets.Extra		Optional nested Extra message with additional precision data for demo analysis.
player_inair	17	optional	bool		True when the player was airborne at the moment of firing.
player_scoped	18	optional	bool		True when the player was zoomed/scoped at the moment of firing.
tick	19	optional	int32		Server tick on which the shot was fired.

Referenced by (1): CMsgTEFireBullets

Field	Number	Label	Type	Default	Description
aim_punch	1	optional	CMsgQAngle
attack_tick_count	2	optional	int32
attack_tick_frac	3	optional	float
render_tick_count	4	optional	int32

CMsgPlayerBulletHit

Msg Player Bullet Hit MsgPlayer PlayerBullet BulletHit attacker_slot victim_slot victim_pos hit_group damage penetration_count is_kill through_smoke

Sent to the attacker (and optionally team) when a bullet registers a hit. Used by the client to display hit-marker feedback and play hit sounds.

Wire id: ECsgoGameEvents.GE_PlayerBulletHitId = 453

Field	Number	Label	Type	Default	Description
attacker_slot	1	optional	int32	-1	Player slot index of the shooter.
victim_slot	2	optional	int32	-1	Player slot index of the entity that was hit.
victim_pos	3	optional	CMsgVector		World-space position of the victim at the moment of impact.
hit_group	4	optional	int32		Hit-group constant (head=1, chest=2, stomach=3, leftarm=4, rightarm=5, leftleg=6, rightleg=7).
damage	5	optional	int32		Raw damage dealt before armour reduction.
penetration_count	6	optional	int32		Number of surfaces the bullet penetrated before this hit.
is_kill	7	optional	bool		True if this hit resulted in the victim's death.
through_smoke	8	optional	bool
