Is it possible to make larva's non-stop creating, the action (trigger)with create unit's larva reqires creep dosen't work. This is a way to make zerg fast bulding unit's - don't wait for the time when larva i spawned. Usually you have to make a 60 hive's lol.

You can't create larva with triggers, so unless you want to make a mod, you can't speed up larva spawn time.

Well you could have a computer player w/ like 100+ hatches, and move the larva over, but eventually you would need to wait for the larva spawn on those as well.

Stack about 300 hatcheries?

I guess, but pressing S (select all larvae) will only select the larvae from that hatch, so you would have to manually select.

Click and drag, it's easier anyway.

Well, since it's probably not a melee map, it doesn't matter (though pressing hotkeys is faster than click and drag).

51 Locations, label them whatever you want, and no, do not put WHATEVER YOU WANT on all the locations. Ensure that the last location surrounds the 50 current locations
50 Locations must be 3x4

Trig-1
Spawn Hatchery at loc A (larva will spawn)
wait 3 mill sec
Remove/kill Hatchery at loc A
wait 3 mill sec
Preserve Trigger

Trig-2
Run AI Script Junkyard Dog at Loc-51
Move to "Area"
OR
Move to "Area"
Run AI Script Junkyard Dog at "Area"
