Every list item in a context-menu is an Action(). Located at the heart of server/player/action.js, the Action() class is straight forward and simple. Most of the meat of its method reside in the player handler file at server/player/handler.
When you click any item in a context-menu, the event fires off player:context-menu:action to the server. Upon reading it, the following happens:
'player:context-menu:action': (incoming) => {
const miscData = incoming.data.data.item.miscData || false;
const action = new Action(incoming.data.player.socket_id, miscData);
action.do(incoming.data.data, incoming.data.queueItem);
},The miscData is data attached based on the context. For example, if the context is wearSlot, the miscData will be the integer of the slot it clicked on. If it's inventorySlot, then it will attached the slot # it clicked on.
Upon the execution do(), the action prepares the data for the player event handler. It will also make some calculations such as the tile ID it clicked on (if applicable), and to queue other actions (if applicable). After all is done, the player events handler takes over.
When an action is executed, it uses the actionId provided and looks inside the server/players/handlers/actions/index.js and looks for the appropriate method.
Then, it will perform the task and hand and update the global world object accordingly and send the Socket update back to the client or all clients.
