You can check if a script is running serverside, clientside or in singleplayer using functions provided by ACSUtils.
In singleplayer, the same engine instance is both a server and a client. Both IsServer()
and IsClient()
return true in singleplayer.
In ZDoom and GZDoom multiplayer (but not Zandronum's), all players are both servers and clients, just like in singleplayer.
bool IsServer()
– returns true if the script is running on a server.bool IsClient()
– returns true if the script is running on a client.bool IsServerOnly()
– returns true if the script is running on a server that is not also client.bool IsClientOnly()
– returns true if the script is running on a client that is not also server.The definitions above enable writing ACS code that functions correctly in both singleplayer and multiplayer without singleplayer being a special case.
