Pirate Bases, Raids, and Objectives

A primary gameplay role  of player-built colonies is getting the player into trouble. Generally speaking, this trouble should be resolved through combat, since combat with context and real stakes is fun. And, after all, what would be the point of building a battlestation if your colonies never got attacked?

One natural source for this kind of trouble is, of course, pirates.

Revisiting the Intel UI

How the player finds out about what’s going on in the Sector – and specifically, what opportunities there are for them to take advantage of – is really important. Some examples of this kind of information, or “intel”, are a bounty posted by a faction, a mission to analyze a probe on the outskirts of the Sector, ongoing hostilities between major factions, the player’s recent discoveries, and so on.

Minefields

Space-mines are too cool a concept not to get into Starsector at some point. We’ve talked about them internally many times in the past, and while the idea is very neat indeed, there are several design pitfalls to watch out for. What I’d like to do in this post is talk about the design process for minefields – what the impetus for adding them was, how I approached their initial design, and how it evolved during the implementation.

Motivation
First off, why add mines now? The answer is for orbital station battles – those present several design challenges, one of which is that they both need to start off strong at the lowest “orbital station” tier, and grow in power as they progress to “battlestation” (tier 2) and “star fortress” (tier 3).

A battlestation is notably bigger and stronger than an orbital station, and that’s nice upgrade. A star fortress, however… one can’t just glom on more modules and make it bigger. Having too many modules makes a station fight less interesting – the station becomes just a mass of stuff to shoot at rather than individual modules with strengths and weaknesses.

What we want is for the star fortress upgrade to make the battlestation more powerful while not compromising what makes the original design interesting. There are several components to this, and one of them is a minefield maintained around the star fortress.

Orbital Fleet Behavior

This blog post is a bit different than usual – instead of talking about a major new game mechanic, I’d like to instead take a quick – but in-depth – look at something relatively minor, but that I thought was interesting. I will, of course, continue to write regular-style blog posts as well.

In Starsector, fleets will often orbit a planet for some time – trade fleets offloading cargo, patrols preparing for duty, and so on. The orbits of some well-to-do colonies can get quite crowded, with fleets overlapping each other and being difficult to pick out. This isn’t a huge problem in terms of game mechanics, but it’s still occasionally inconvenient and just messy to look at.

The other day, encountering a particularly egregious case, I wrote a quick algorithm for the fleet AI to use to avoid overlapping other orbiting fleets  as much as possible.

Blueprints, Doctrine, and Production

How starships get produced has been heavily abstracted so far – there’s a colony, and it spawns fleets made up of faction-appropriate ships, and that’s about all there was to it. To be fair, that’s all that needed to be there, since it was not something the player could interact with in more detail than attacking those fleets.

Now that the player can establish colonies and manage a faction of their own, we need more detail. Not so much that it’s a chore to manage, but enough to cover the things the player will naturally want to do.

If you’ve been keeping track of the backstory, most heavy manufacturing in the Sector is done using “blueprints” – precise specifications for building a ship or a weapon, that an automated factory can use to build the item. Copying these is difficult-to-impossible, and their dwindling supply contributes to the gradual decline of the Sector. This is the base we’ll use to develop the manufacturing mechanics, making adjustments to cover the demands of gameplay, as needed. That is to say, if blueprints have to work a certain way for the gameplay to come together, then hands will be waved.

Blueprints
A “blueprint” is an item the player can find and right-click to “learn”. For example, they might acquire the blueprint for a Medusa-class destroyer or a Heavy Mauler, a ballistic weapon. This works similarly to how players learn new hull-mods. After a blueprint has been learned, the player’s heavy industry becomes capable of producing the items in question – there are lots of details here, and we’ll get to those in a bit, but that’s the basic system.
