Implementing Steam Workshop + Mac/Linux beta uploaded

As you know, over the last few weeks we've been breaking all links between the game and The main reasons for this are to solve all problems people were having with logging in and other server communication. What this means is that every feature requiring a web request to has to be rewritten to use some kind of alternative resource. These features may need to retrieve or save some data, like what suit the player is wearing. Most of the features were like this, only needing the link to to store or load some data. These features could be easily replaced by using the Steam Cloud to store the data. Steam Cloud doesn't complain if the player doesn't have an internet connection (it just saves locally, and 'syncs' with the cloud when it can).

Some of the features requiring, however, needed a little more work. Some of these features are the following:

Synchronization of customization in multiplayer
The only thing that was sent to the other player directly was the user ID. Using these IDs, each player's customization was downloaded from More on how was replaced for this feature in Jeroen's part below.

Community missions
The community mission feature is one of the few actually needing some kind of central place to store data. This is because potentially every player can create a community mission, so you can't just send it to other players like the customization in a multiplayer session.
We thought the best central place to store community missions was Steam Workshop. This Steam feature is a good fit for community missions, as it is designed for storing user generated content. What this means is that if World of Diving community missions work with Steam Workshop, you get a lot of features already implemented into Steam for free. These features include commenting and voting on items and using the Steam overlay to remove or edit items. Unfortunately in this case we already implemented these features, so they won't be very beneficial for us.

Early this week we also put up Mac and Linux versions for the World of Diving beta, so players on these platforms can also enjoy the latest (but potentially unstable) features. I'll copy the warning of last week so it won't be forgotten:

WARNING: For those entering the beta, after opting in, you shouldn't opt-out of it and play the live version. If you do this, everything should work (but this isn't tested), but all actions you then do on the live game will not be transferred when the update goes live or you re-join the beta. This is because the user data is only transferred to your local machine (and the Steam cloud) once.

AI update

Last week I have been working on more fish! We have managed to push a lot more performance out of Unity by both changing our way of thinking about the AI and working around some of the slow implementations of Unity. The major change that we have applied is that all AI is now calculated on other threads instead of the main Unity thread. A bonus perk we achieved by using this method is that we can keep the game on a high framerate, even if the AI calculations become too heavy. We are still discussing about what will happen when the update rate drops under 60hz. Possibilities we are exploring are the following: tuning down the AI complexity ( which is a very dangerous change -- one of the main AI calculations is the avoidance of objects. If we simplify these calculations we will go back to flying and penetrating fish ), making some fish move away from the vision of players and then dissapear, so we practically only have to simulate less AI, and the last one is to simply lower the update rate of the AI, which will make fish appear stuttery, but won't have weird behaviours.

Last week I gave you a bonus GIF with a lot of arrows "swimming" around. I will do a follow up on this in the coming weeks. Our new AI system provides us with a base for some major gains. More about this soon!

Continued unlinking of

This week we have continued the implementation of local user data using the Steam cloud.

Previously, the customization of other players was retrieved from, so to fix multiplayer and customization of other players, this needed to be synchronized efficiently over the network. So I've implemented this using the Photon network system we use.
Another issue that was still standing was daily missions and XP rewards from daily missions. This has been implemented now without the use of the server, so players can once again level up their character. Stay tuned for next week for an update to the beta.

I like this update. Something I'd love to see implemented is the ability to create your own levels? might satisfy everyone while we all wait for procedural generation.

I remember that one of the advantages of moving to Unity 5 was the capability of getting more objects into the environment. Now with Trevor's performance improvements to the fish AI, the dream of a more dynamic level is coming about. Nice work guys!

Good point, just did!

So, are you going to update to Unity 5.2 like Subnautica just did? Also, you really need to update the water surface and light grading by depth in the game like "Stranded Deep" did and "Subnautica" will be this week in Experimental for the eventual "H2.O" update. Proper lighting that changes by depth and realistic surface water with waves and foam are a must for a game like this.

In this pre-alpha trailer, you can see the surface water with very nice physics: . I can't believe this was almost 2 years ago....
