2021-06-03Codechange: use "[[maybe_unused]]" instead of a wide variety of other ways ↵Patric Stout
we had While at it, replace OTTD_ASSERT with WITH_ASSERT, as this is always set if assert() is valid. No matter if NDEBUG is set or not.

2021-03-26Feature: allow setting a custom terrain type to define highest peakPatric Stout
At least, TGP will try to reach it. It heavily depends on the map if it is reachable at all. But for sure it will do its atmost to get there!
2021-03-26Feature: auto-detect map height limit based on generated mapPatric Stout
This opens up the true power of the TGP terrain generator, as it is no longer constrainted by an arbitrary low map height limit, especially for extreme terrain types. In other words: on a 1kx1k map with "Alpinist" terrain type, the map is now really hilly with default settings. People can still manually limit the map height if they so wish, and after the terrain generation the limit is stored in the savegame as if the user set it. Cheats still allow you to change this value.
2021-03-26Change: rename setting "max_heightlevel" to "map_height_limit"Patric Stout
This better reflects what it is, and hopefully removes a bit of the confusion people are having what this setting actually does. Additionally, update the text on the setting to better inform users what it is doing exactly, so they can make an educated decision on how to change it. Next commit will introduce an "auto" value, which should be the new default. The rename has as added benefit that everyone will start out on the "auto" value.
2021-03-26Feature: setting to indicate desert coverage for tropic climatePatric Stout
This is an indication value; the game tries to get as close as it can, but due to the complex tropic rules, that is unlikely to be exact. In the end, it picks a height-level to base the desert/tropic line on. This is strictly seen not needed, as we can convert any tile to either. But it is the simplest way to get started with this without redoing all related functions.
2021-03-26Feature: setting to indicate snow coverage for arctic climate (replaces snow ↵Patric Stout
line height) Setting the snow coverage (in % of the map) makes a lot more sense to the human, while still allowing the niche player to set (by finding the correct %) a snow line height they like. This makes for easier defaults, as it decoupled terrain height from amount of snow. Maps can never be 100% snow, as we do not have sprites for coastal tiles. Internally, this calculates the best snow line height to approach this coverage as close as possible.
2021-01-08Fix: for arctic and tropic, make sure we have at least a few hills (#8513)Patric Stout
Without hills, not all industries can be generated, which means that with a default configuration you get errors. This is far from optimal, of course. This now forces that there is at least some hills, even when you are using very-flat. This is a stopgap solution, but a proper solution requires a full rewrite of the terrain generator, which is not a 2 minute (or even 2 week) job. To make sure flat is still flat-ish, reduce the default snow-line-height to 10, making it look a lot better on smaller maps. This is a compromise between being able to have flat maps and still having all industries on arctic.
