For use with key exists:

es_xset key_exist 0
es_exists key_exist key Sounds event_var(userid) // checks if a key named with their userid exists
if (server_var(key_exist) = 0) do
{
//do code if key doesn't exist i.e. create the key
}
else do
{
//do code if key exists.
}

For use with userids:

es_xset userid_exists 0
es_xexists userid_exists userid 34
if (server_var(userid_exists) == 1) then kickid 34

For use with maps:

es_xset map_exists 0
es_xexists map_exists map cs_italy
if (server_var(map_exists) == 1) then changelevel cs_italy

Notes

• You should always use es_set before es_exists because the variable is not always set to the correct value.
• Es_exists script looks up if a script is loaded by ES.
