Command Bytecode Arguments Description
cls_skill 0x0e Long Entity_DPID
Short Struct_Offset
Fixed Skill
Send an entity skill (TCP).
Struct_Offset gives the byte offset
of the skill in the
A4_ENTITY struct.
cls_skill3 0x0f Long Entity_DPID
Short Struct_Offset
Fixed Skill[3]
Send an entity vector skill (TCP).
Server Messages
The following commands are used for transferring information from the server to either a
specific client, or to all clients connected. Server-client communication uses the reliable TCP
protocol for important messages, and the unreliable UDP protocol for unimportant messages.
Command Bytecode Arguments Description
svc_fill 0x01
Filler byte for inflating TCP and
UDP messages to at least 8 bytes.
svc_create 0x03 Short Entity_Index
Short Identifier
Created entity with given index
(TCP).
svc_remove 0x04 Short Entity_Index
Removed entity from server (TCP).
svc_entsound 0x05 Short Entity_Index
Short Sound_Index
Scale(2000) Volume
Long Sound_Handle
Play an entity sound on the clients
(UDP).
svc_effect 0x06 Short Action_Index
Short Number
Position Start[3]
Fixed Vel[3]
Generate a particle or beam effect on
the clients (UDP).
svc_info 0x07 Long 0x11191218
Byte Protocol_Version
Float Server_Time
Float Frame_Time
Send a sync value and the server
time to the clients (TCP). This is sent
once a frame.
svc_var 0x0a Short Var_Index
Short Var_Length
Fixed Var[Var_Length]
Send a variable to all clients (TCP).
svc_string 0x0b Short String_Index
String Text
Send a string to all clients (TCP).
svc_skill 0x0e Short Entity_Index
Short Struct_Offset
Fixed Skill
Send an entity skill particularly to
the entity's client (TCP).
Struct_Offset gives the byte offset
of the skill in the
A4_ENTITY struct.
svc_skill3 0x0f Short Entity_Index
Short Struct_Offset
Fixed Skill[3]
Send an entity vector skill
particularly to the entity's client
(TCP).
svc_update1 0x40..0x7f Short Entity_Index
(Parameters see below)
Update entity parameters 1 (UDP).
svc_update2 0x80..0xbf Short Entity_Index
(Parameters see below)
Update entity parameters 2 (UDP).
