Setup

Positions:

• upgrader creep next to the controller
• storage structure next to the upgrader
• filler creep next to the storage
• pathStart position next to the storage

From pathStart all (sources, controller, mineral, mid of each exit) paths are calculated and saved. The longest path is used to place structures (spawn, extension, lab, observer, terminal, tower) next to it. Next to filler a link, tower and power_spawn is located. Links are placed next to the sources and at the paths to the exits. Layers of walls are placed at the exits, positions within the precalculated paths are replaced by ramparts.

Pathing

Paths are precalculated and cached and reused by most of the creeps.

Swamps are ignored because roads will be built automatically over time. The creeps only move on the precalculated paths (to reduce complexity). Instead, blockers are recognized and structurer are sent to destroy the structure, carry creeps try it as well.
