Overview
Happy New Year!! After taking a break last month, I am back in full swing development. Expect a bi-weekly update for the next 2-3 months.
Improved AI
Opponent AI is the most important and complex part of Star Scum. Creating an opponent AI that can play a complex card game with a large board, hidden information and arbitrary cards and do it fast enough to not make the player wait too long even on older hardware, has been quite a journey. This patch is the next big step in that journey.
Over the course of the game's development, I experimented with a number of approaches, some of which worked really well but were too slow for the complexity of the game. Recent optimizations in how the card scripts sequence events into the game allowed me to run simulations fast enough to try an all around better approach to how the AI makes decisions. I will probably write a separate post just on this, but in short, the AI is now smarter, faster and uses a lot less memory! It's also more inventive, unpredictable and interesting to play against.
There are a few drawbacks to it as well; because it a bit more loose, it will sometimes play cards that do not do anything or even benefit the opposing player, especially on lower difficulties. But I find the overall improvements to be worth the occasional really bad decisions. This algorithm also opens up a lot more room for tweaking decision heuristics, so I am confident I can help guide the AI from making them.
Crystalloid Updates
Crystal Growth (and by extension Crystalloid decks) have so far been the most experimental and thus most broken cards. This update reworks them to be less random and they now grow towards closest teleporter when on friendly ship and towards the core when it's on the enemy ship. They now also grow by cloning instead of by spawning a new Crystal Growth, inheriting all of their attributes. These changes make them into a much more formidable foe.
