1) using ProxySpace with more than one client, with separate bus spaces

if only one client is using a remote server, only step (a) and step (d) are relevant. The clientID argument can be left out then.

before you start
|
||
|
|
|
||
|
|
remember to synchronize your system clocks. This can be done by:
|
||
|
|
@section{definitionList}
|
||
|
|
|
||
|
|
## in macOS || SystemPreferences>Date&Time: set emphasis::"Set Date & Time automatically":: to true.
|
||
|
|
## in Linux || set the ntp clock
|
||
|
|
::
|
||
|
|
a local time server is better than the apple time server. if you cannot sync the time, you can set the server latency to
|
||
|
|
@racketblock[nil::. This will break the pattern's functionality though.

|

@section{subsection}
|

|
|
a) boot the (remote) server and create a local model
|
||
|
|
|
||
|
|
|
||
|
|
@racketblock[
|
||
|
|
s = Server("serverName", NetAddr(hostname, port));
|
||
|
|
s.options.maxLogins = 16; // or the maximum number of participants in the network
|
||
|
|
s.boot; // you cannot directly boot a remote server instance, but this initializes everything that is needed
|
||
|
|

|
||
|
|

@section{definitionList}
|

|
|
## serverName || can be any name
|
||
|
|
## hostname || is an ip address, or if you have a name resolution, a network name
|
||
|
|
## port || the port on which the server is listening. default is 57110

b) from each client, initialize the default node and set notify to true:
|
||
|
|
|
||
|
|
|
||
|
|
@racketblock[
|
||
|
|
s.boot; // this will initialize the tree and start notification
|
||
|
|
|
||
|
|
// if needed, a server window can be created:
|
||
|
|
s.makeWindow;
|
||
|
|
::

|
|
||
|
|
|

]
|
||
|
|
@section{subsection}
|
||
|
|
c) now create a ProxySpace from the server:
|
||
|
|
|
||
|
|
|
||
|
|
@racketblock[
|
||
|
|
p = ProxySpace.push(s);
|
||
|
|
::
