Here is the last v0.8 update (but for possible hot fixes).

In addition to the sand graphic and other various improvements and bug fixes, two major bugs from the previous v0.8.3 have been fixed : the trucks loading too slowly, and the game freezing when building a rail end over a pentagon (in a specific direction). Very sorry for those bugs!

We are now going to focus on the v0.9, which will bring a lot of new content and a simple story.
v0.9 will be incompatible with previous saves (starting with the next beta update), so I've created a "v0.8.4 backup" steam branch. This way you will always be able to continue to play with older games.



Improvements:
- Sand on shores
- Changed items Max Count UI
- GeForce Now activated
- Dynamite can dig in negative altitudes
- Ships in transports help page
- New help page about Backup Supply Option
- Reduce tiny ponds (holes) at the world generation

Balance:
- Smooth terrain tool softer
- Ships loading/unloading drones priority improvement
- Level 2 requires more factories

Bugs fixes:
- Fixed trucks loading speed
- Fixed crash crash buliding rail end over an heptagon
- Fixed camera view area (sometimes the ground was disappearing)
- Fixed input key change bug
- Fixed city supply / waste centers panels colors
- Fixed mineral ground color with the non default mineral options
- Fixed corrupted saves making the save page UI going crazy

Minor:
- Add an error message if we try to load a new save with an old game build

As long as water is not too deep, roads and rails will now automatically become bridges when above water. And as they are now created procedurally, it also fixes their visual glitches (near pentagons).



Major Improvements:
- Automatic rails and roads bridges

Improvements:
- FX: Trees moving with wind
- FX: desert wind and particles, forest leaves
- Sun in the skybox
- Reduce warnings size (grouped)

Balance:
- Initial water quantity (world creation option) balance.
- Water apparition a bit more slowly
- Faster trains loading/unloading acceleration
- Colors change on overlay selection and lines
- Pumping stations still works over a bit of water

Bugs fixes:
- Fixed visual glitches of roads and rails near pentagons or on strong elevations
- Fixed lua mods loading: only load "mod.lua" file, which must include the others (it was loading all .lua files)
- Fixed city cars not visible in pause
- Fixed sound effect in pause
- Alt tab doesn't freeze enhanced view anymore
- Fixed road pathfinding and pentagons/heptagons

Minor:
- fixed mineral creation in dev mod
- Retake of dead city models
- Display active mods in home screen
- Wiki updated
- Rail stop model changed
- Modding: recipes duration can be modified
- Modding: option refund not free

This update brings some nice little vehicles flying over cities to make them more lively, a new skybox (no more of the low resolution one), and a lot of bug fixes and improvements, mostly from player feedbacks and suggestions (thanks again for your help!).



Improvements:
- Added flying cars in cities (visual effect)
- New skybox (infinite resolution)
- Help pages updated
- More items & recipe visibles in choice popup

Balance:
- Give more assembly plants and factory at new game start

Bugs fix:
- Fixed dynamite recipe (requires oxygen)
- Fixed freeze with corrupted dump item
- Fixed freeze at loading with corrupted dam pump item
- Fixed some issues with depot or lines having a bad item assigned (potentially creating corrupted depots or dumps)
- Fixed some errors when selecting a recipe
- Fixed depots & containers altitude update with water altitude change
- Fix links opening steam instead of browser
- Fixed some corruption cases
- Fixed city duplication in creative mod
- Fixed city enhancedview color
- Fixed keyboard (including WASD) locked when pressing Return on a item count limit or city name
- Fixed credits ending
- Fixed boats coming out of water at game load

Minor:
- Added a tooltip for the item count limit
- Updated localisation
- Set backup depot text bigger
- Some hidden stuff for v0.9

Here is a small update, mostly to fix various issues from v0.8.0. Especially one, very bad, that was happening sometimes after destroying an item in a new world. I'm very sorry for everyone that experienced it.

(Edit) The Steam Workshop has also been activated.


Improvements:
- Ships: add sounds, smoother movement

Bugs fix:
- Fixed the "destroy item" bug
- Fixed water freeze for in games played more than 80 hours (simulation time)
- Ships: fix destination change and deletion bug ; remove buoy build fx
- Fixed resources of depot destroyed when change of item
- Fixed invisible water on reload
- Fixed water glitch on dam deletion on ground

Minor:
- Fixed +1 pop achievement for mods with different nb of cities
- Fixed refund of cross ways
- Warnings about water stay longer
- Ships try to reroute less often
- Modding: Default mod modifications commented ; change upload confirmation text
- New hint about recycling
- Add link to workshop
- Escape close console
- Fixed "Full" on assembly plants with full inputs.
- Fixed UI issue when planet name too long

v0.8 is a major update for the planet's environment. Enjoy the new world generation with vast oceans and container ships to cross them. Open paths with the new dynamite and terrain tools. Get a better overview of your industry with a new zoom that show the atmospheric currents and cloud simulation, and an enhanced and unified view. Visualize ground humidity and choose between the five available trees, each with their own temperature and humidity requirements.
Five musics have also been added, and the original soundtrack will be available in a few days (for $5).

I suggest to start a new world to enjoy the new generation, but you can continue your old save. However, it will add a lot of water. If you wish to avoid such change, you can activate the "v0.7.5" beta (in the "beta" menu of the steam properties of the game) to keep playing the old version.
Edit: if you have installed a bepinex mod, you might have to remove it, as it could make the loading freeze.

The game will have a 20% discount during the Summer Sale, and then its price will increase from $12 to $14. It was the same with v0.7 and will be the same with v0.9: the idea is that you pay only for what is already done, rather than for promises.

HOTFIX on 2024-07-01 :

Plan B - v0.8.0 build 881 HOT FIX

• Fixed loading freeze when a default mod was created, and fix issues when removing a mod
  
• Fixed freeze with some corrupted containers dump items
  
• Fixed some refresh of normal texture

Here are some news about the v0.8 update! It's progressing well and should soon be complete.

Here is what is already done:
- new ocean and mountain generation, and improved water simulation.
- new view with visible clouds and city lights, and improved enhanced view (cf. screenshots below).
- dynamite (and other terraform tools) item.
- basic modding support (lua files to change item parameters and balance, 3D models, textures, sounds, etc.)
- additionnal musics

And here is what is yet to be done (if no unexpected issue) :
- container ships
- two new trees types
- improve mineral & cities placement at planet generation.

As with the previous major update, the price of the game will rise a bit. From $12 now it will rise to $14, but only after a 20% discount for a week at v0.8.0 release.
As i had explained before, the idea is that you pay only for what is already done, no promises, and future update are bonus.
The soundtrack will also be made purchasable with this v0.8.

A summary of the roadmap:
- v0.7 was about quality of life updates
- v0.8 is about the planet generation, the environment, the modding
- v0.9 will be about new content (new items, objectives and a simple story)
- v1.0 final release will be about the same as v0.9, once it's enough polished and balanced.

v0.8 is progressing well: new ocean generation, basic modding support and new views (one with visible clouds) are done. Don't hesitate to activate the beta branch to test it! Still a few features to work on before releasing it to everyone.

So, in the meantime, I would like to rewrite here an old post from twitter (2019!) that was explaining the hexagonal generation I've developped for Plan B. Here it is:


How to create a sphere made of hexagons? Hexagons of similar size and orientation?

The most common way to do that is to start from a regular icosahedron (solid of 20 of equilateral triangles), then subdiving each triangle (sphere tessellation). Each triangle vertex becomes an hexagon, as you can see in this pic (credits https://twitter.com/AndyGainey ; I'll come back to him):
Here is a sphere with 5 subdivisions (~10,000 hexagons). It's very nice, that's what I initially planned to use... but it's actually bad for a game. Not because of the 12 hidden pentagons, but because of the non-uniformity of the size, shape and orientation of the hexagons.
Here is what you can see at different positions of the sphere ; north pole being on top. Hexagons are of various shape, size, and orientation ; the result would be awful when you scroll in the game, very disturbant.
There are other ways to do this sphere tessellation, like the very interesting Healpix, which garantees the same size for each area, but have non-uniform shape, and squares instead of triangles/hexagons. https://healpix.sourceforge.io http://montage.ipac.caltech.edu/docs/HEALPix/
A very special and incredibly imaginative solution is the one of
@AndyGainey, explained in detail here: http://experilous.com/1/blog/post/procedural-planet-generation
To avoid avoid pentagones and predictable irregularities, he decided to do the total opposite: going full irregularity.
When irregularity (in size, shape and number of edges) is everywhere and random, the surface actually becomes regular - homogeneous in its irregularity. Really brillant, but not what I need for my game, as I really want regular hexagons.
So, what I do is that I divide the sphere in vertical "slices". Inside each slice, the triangles/hexagons are set in perfectly horizontal rows, and are (almost) pefectly equilateral. The non-uniformity is grouped in the links between slice.
One big advantage is that the more hexagons there are, the more regular it becomes. And for my game, I'll have a lot, lot of hexagons. Here is the sphere with a few thousands ones.
And here is a portion of the surface, with a few millions of hexagons. Can you spot the irregular shapes ? Not easy ! They should definitely not be a problem when playing on this field.
The "Icosahedron tessellation" method produces only 12 pentagons. With my method I get much more: 720 for a sphere of 14000 hexagons (5%). But the more hexagons, the better the ratio is. For 10 millions of hexagons, only 0.2% are pentagons or heptagons.
I have calculated the variation in the triangles edge lengths (are hexagons are uniform in shape and size ?): I get a coefficient of variation of 6.5% for the icosahedron tessellation ; but only 1.6% with my method.
The best advantage of my solution is about the orientation of the hexagons (are they "horizontal" ? I check the angles of the triangles edges). I get a coefficient of variation of only 3.8%, compared to the 55% with the icosahedron tessellation!


Here it is. 5 years later, i have no regret using this system, i still can't think of a more suited one. Although, i can say now that i definitely underestimated the technical complexity of using this system in a full game, to properly manage the slices borders.

If I had had more time, i would have loved to research further in this matter. Maybe find a way to avoid the slices. Or something else.
If any of you know of some interesting research about it, i'd be very interested to know about it!

Finally, the major performance increase upgrade is live! You might get x2 or better boost in framerate.
It was a much bigger task than anticipated, but we took the time to explore every optimisation that we could think of. And it was definitely worth it, the result is much better than anticipated.

We also took the opportunity to add the long requested intermediary zoom (between the zoomed levels with all details and the planet-scale view).

We also worked on several v0.8 very nice features, but those are hidden for now... Don't hesitate to activate the beta branch and/or follow the discord to get news of them in the following days!

And so this v0.7.5 was the last of all "quality of life" updates, now we'll work full time on new features, for v0.8 (water, terrain, environment) and then v0.9/v.1.0 (story & new items/objectives).
