How to Get Your Units Unstuck


@mindme , @ketroc , and @chad join me on tackling one of the most persistent bot problems: stuck units. The session dives into SC2 action errors, pathing queries, observer mechanics, cyclone and banshee edge cases, and how emergent behaviors like concaves, baiting, and mineral-line pathing arise without being explicitly scripted.

Key Takeaways:

  • :brick: Action errors are the key to detecting stuck units by listening for failed abilities like “could not reach target” and reacting immediately.
  • :compass: Pathing queries confirm real traps by testing reachability to known valid locations before triggering rescue logic.
  • :hammer_and_wrench: Rescue logic beats prevention alone using medivacs, warp prisms, or liftable structures to extract trapped units.
  • :eye: Observer mechanics enable smarter expansion control by revealing edge creep tumors that block base placement.
  • :brain: Emergent micro outperforms rigid scripts as swarm-style decisions naturally create concaves, baiting, and flanks.
  • :bullseye: Effect-based intel expands awareness by tracking lurker spines, liberator zones, and other non-unit threats.
