 # Writing your own Plugins
 
-So, you love the functionality of the webclient, but your game has specific types of text that need to be separated out into their own space, visually.  There are two plugins to help with this.  The Goldenlayout plugin framework, and the older Splithandler framework.

 You can then add "mycomponent" to an item's componentName in your goldenlayout_default_config.js.
 
 Make sure to stop your server, evennia collectstatic, and restart your server.  Then make sure to clear your browser cache before loading the webclient page.

-## Older Splithandler
-The splithandler.js plugin provides a means to do this, but you don't want to have to force every player to set up their own layout every time they use the client.
-
-Let's create a `mygame/web/static_overrides/webclient/js/plugins/layout.js` plugin!
-
-First up, follow the directions in Customizing the Web Client section above to override the base.html.
-
-Next, add the new plugin to your copy of base.html:
-```
-<script src={% static "webclient/js/plugins/layout.js" %} language="javascript" type="text/javascript"></script>
-```
-Remember, plugins are load-order dependent, so make sure the new `<script>` tag comes after the splithandler.js
-
-And finally create the layout.js file and add the minimum skeleton of a plugin to it:
-
-```
-// my new plugin
-var my_plugin = (function () {
-    let init = function () {
-        console.log("myplugin! Hello World!");
-    }
-
-    return {
-        init: init,
-    }
-})();
-plugin_handler.add("myplugin", my_plugin);
-```
-
-Now, `evennia stop`, `evennia collectstatic`, and `evennia start` and then load the webclient up in your browser.
-Enable developer options and look in the console, and you should see the message 'myplugin! Hello World!'
-
-Since our layout.js plugin is going to use the splithandler, let's enhance this by adding a check to make sure the splithandler.js plugin has been loaded:
-
-change the above init function to:
-```
-let init = function () {
-    let splithandler = plugins['splithandler'];
-    if( splithandler ) {
-        console.log("MyPlugin initialized");
-    } else {
-        alert('MyPlugin requires the splithandler.js plugin. Please contact the game maintainer to correct this');
-    }
-}
-```
-
-And finally, the splithandler.js provides provides two functions to cut up the screen real-estate:
-    `dynamic_split( pane_name_to_cut_apart, direction_of_split, new_pane_name1, new_pane_name2, text_flow_pane1, text_flow_pane2, array_of_split_percentages )`
-and
-    `set_pane_types( pane_to_set, array_of_known_message_types_to_assign)`
-
-In this case, we'll cut it into 3 panes, 1 bigger, two smaller, and assign 'help' messages to the top-right pane:
-```
-let init = function () {
-    let splithandler = plugins['splithandler'];
-    if( splithandler ) {
-        splithandler.dynamic_split("main","horizontal","left","right","linefeed","linefeed",[50,50]);
-        splithandler.dynamic_split("right","vertical","help","misc","replace","replace",[50,50]);
-        splithandler.set_pane_types('help', ['help']);
-
-        console.log("MyPlugin initialized");
-    } else {
-        alert('MyPlugin requires the splithandler.js plugin. Please contact the game maintainer to correct this');
-    }
-}
-```
-
-`evennia stop`, `evennia collectstatic`, and `evennia start` once more, and force-reload your browser page to clear any cached version.  You should now have a nicely split layout.
