Not because it saves you from frustration. That's why I strongly refer people to use their own engine, unless they make heavy use of Unity's Asset Store, which is IMO the only reason to go Unity.

Otherwise it just takes time, but it's a consistent amount of time (the rate at which I learn), with the added benefit that I understand everything low level & know my own code inside & out. It's always when other people enter the fray, I bog down enormously. I rarely have a problem learning fundamentals / low level stuff, but nearly always have a problem learning to use other people's tools, assets, code, etc.

Really, all of game development is 99% learning how to do or thinking of what to do versus actual doing. However these types of situations are probably the exception forcing you to deal with rare edge cases as they lead to game breaking inventory duplicates or really bad data synchronization problems.Ĭlick to expand.So true.
For most situations like this I would even advise that getting something out there in front of players is more important that worrying about 99.999% edge cases. Having two players take the same item from the same chest at precisely the same instance just isn't going to happen that often. Worst part of this is that you must account for extreme edge case conditions. For a lot of these issues you must force the server to be authoritative and this means the server must verify and approve cases like moving inventory to and from a chest, using items, interacting with npc inventories, etc. These are some of the hardest issues to debug you will ever face as a developer. These are intermittent issues when they manifest and hard to track down. The biggest issues with multiplayer is now we have to worry about data collisions, data synchronization and racing conditions.

In a multiplayer environment, you'll wish it was that simple:ġ) a player opens a chest and triggers an open chest event that is sent to serverĢ) the server processes the open chest even, pulls the chest inventory from the database and sends it to the playerģ) the player processes an open chest response event and fills a local data type with the chest inventory data sent from the server.Ĥ) the player either opens a chest ui display either when they initially hit open or when they receive the open chest response event, either way we need to handle the possible delay of data in some way ("loading." on the chest ui screen, etc)ĥ) when a player takes inventory from the chest, they send a put/take chest inventory event with inventory taken or placed in the chestĦ) either update the result of taking or placing inventory immediately (and eventually update agian with step 10) or wait for the response from the server to update the displayħ) the server processes the take/put chest inventory event, updating the database for both the player and the chest, the server verifies that the proper items inventory is available for the player to take transferring only what is availableĨ) the server sends out a take/put chest inventory response event, containing all of the updates it actually did (note that this could be different than what the player actually requested to be done)ĩ) the server also sends out a chest inventory update event to all other players that have that chest open as the chest inventory has now changed in some way.ġ0) the taking/putting player processes the take/put chest inventory response from the server possible reconciling any differences between what the server updated and what the player expected to be updated.ġ1) the player updates the display of both the chest inventory and player inventory based on the new dataġ2) other players that have this particular chest open process the chest inventory update event from the server updating their local data and updating the chest inventory display. In a single player environment this pretty easy:ġ) when a player opens a chest, pull the inventory for the chest from the database (for things like this I use sqllite)ģ) when a player transfers an item to or from the chest, update the players inventory, update the chests inventoryĤ) update display of both player inventory and chest inventory For instance, I just recently added support for chests to my current project.
The biggest issue I see with Multiplayer development is the way is scales the simplest of tasks. This learning curve shouldn't be taken lightly though, I still feel, after years of being a developer, that most of the time spent is in learning versus doing. Eventually you will get good enough with your tool of choice that you can avoid most pitfalls. Though the OP seems to have the most issue with the technical learning curve of the sweat of tools available to solve networking in Unity, I feel this problem is at least solved by experience.
