What Most Bots Get Wrong in the Early Game

Apr 30th 2025

Why hello Reader,

You’re scrubbing through the replay, watching that final fight, and you get that familiar feeling — thinking, yep, this is where it all fell apart. Pause, rewind. Actually, the match was lost way earlier, somewhere in the opening few minutes.

In our recent Debug clinic, yup, same story: Dogtato’s Botato was technically solid, but still got flattened by an early proxy rush. A couple of things we picked up on could have set up a different outcome.

In Case You Missed It

  • MicroBot – Overclock continues work on concave formation logic
  • Exploring whether group movement or individual unit control performs better in micro skirmishes

Scout, Scout, Scout

Bot responses only get better with more information, not less.

One tiny scout — one worker — could have changed the whole match. Storing what it sees, checking if there’s no expansion at the natural base less than three minutes in, could flag that something funny’s going on and trigger a code response.

Cancel That

When a building is under construction and starts taking damage, coding a function to cancel the building when it drops below 10% HP can reclaim precious minerals your bot can use for a response. It could be the difference between getting that defensive unit out or hitting the loss screen.

Flexible Build

“What should it build next?” is one of those choices bot makers get tripped up on because you don’t play the game yourself. “Just build a little of everything” might seem like a good default, but telling your bot to walk blindly down tech tree paths can leave it wide open.

Code in build orders that produce an army able to handle most race matchups but that stay flexible enough to respond. You can find good ones on Spawning Tool by searching for economic builds with your bot’s race letter (Protoss, Zerg, Terran) vs X. Example: “P v X” means Protoss vs all races. Or use a Bronze to GM build, like this Terran one from PiG.

Play the opening right, and you won’t have to hack in a dozen edge-case patches later.
