Design

The AI automatically generates a layout for the room and builds the structures for the current RCL. A scout creep or observer explores external harvest rooms. New rooms are acquired if the current number doesn't fit the GCL. Fallen rooms will be survived and basically defended. The AI sends some waves of auto attacks. Minerals are fetched from the extractor and transported to the terminal. Reactions are basically implemented. Depending on a threshold minerals are sold on the market.

Base building

Logic

The number of structures are checked and if applicable new constructionSites are places. Links are triggered to transfer energy to link near the storage. Towers attack incoming creeps or heal my creeps. If no spawn is available nextroomer from other rooms are called, to build up the room.

The basic creep is the harvester which can make sure, that enough energy will be available to build the rest of the creeps. For this we check if a harvester is within the room, otherwise spawn it. For the rest a priority queue is used.

Role

  • upgrader get energy from the storage, puts it into the controller.
  • filler get energy from a link and transfers it to the tower or storage.
  • sourcer get energy from source.
    • Controlled room: Transfers the energy to the link.
    • External room: Builds container, fills container, calls carry to get the energy.
  • reserver reservs an external controller and calls sourcer.
  • carry gets energy from the target container and fills structures and storage on the way back. If there is a creep in front the energy is transfered.
  • scout Breadth-first search based room exploring.
  • harvester moves on the harvester path, and transfers energy to free structures on the path. On low energy in storage, the harvester falls back to the start up phase without relying on anything (storage, links, other creeps).
  • nextroomer moves to target room and builds up that room.
  • repairer build walls and ramparts.

Routing

The routing from start to end is first done on room level:

  • Find Game.map.findRoute(start, end) plus the start room added as first entry in the array. This is stored together with the routePos in memory of the creep.
  • Inside a single room:
    • First room (routePos == 0): Own rooms have a layout set with a path to each exit pre-calculated. The first part of the path name is Start and the second the room to move to.
    • Last room (routePos == route.length -1): the targetId is stored in the memory of the creep. So the first part of the path name is the previous room and the second part is the targetId.
    • Rooms on the path: The previous room is the first part of the path name, the next room is the second part of the path name. The path is cached in the memory of the room with a created attributes to allow invalidation.
