Nobody selects larvas directly? I guess I am a computer then. Way worse than Alphastar tho.

Ha! So I always did that in Brood Wars, but in SC2, I put each hatchery on a hotkey (0, 9, 8, etc.) and then just pick the units I want to queue up. No need to select individual larva any more.

I like to map tilda, tab, and caps lock to 0, 9, and 8 so that my left hand doesn't have to reach as far.

New players (like when I first played) are likely to select individual larva before they do tutorials or learn the hotkeys, but you're right that high level players would almost never select one directly. Maybe after a hatchery has died and there are still larva remaining?

No, it doesn't select the larvae by dragging, it just selects them instantly from the other side of the map. I'd guess it either has a hotkey for the hatcheries and press it and the larvae key instantly without it showing in the replay, or it has a cheat ability to instantly select larvae.

Its API allows it to select units arbitrarily from anywhere (regardless of camera). Camera vision only controls the specificity of data it sees for on-screen units.

Oh, interesting. Thanks for clarifying.

For the type of beast AlphaStar is, they do not sound like simple tasks at all.
