defensebuild_ga will build unit only when computer have air force.. I guess it is the same as defensebuild_gg.

Hmm, sometimes it goes ahead and spams units anyways, though not as badly. It just seems to go crazy when it comes across defensebuild.

Nerco FTW!

Hey guys. I'm back after a long period of hibernation. I've decided to finish this old project I started on a while ago.

Anyway, after studying this thread and other Zerg AI scripts, I have made some changes to the Zerg script used in my mod. It works now, building drones and attacking accordingly, however there is an unexpected crash somewhere that continues to elude me.

Yes, I've implemented 'build(1, Zerg Drone, 40)' scripts because quite frankly, that is the only way I can get the AI to build drones correctly.

The --dronebuild-- code works very usefully as well; the AI will construct a drone every now and then, or replace drones that were used to morph into structures.

Now, the crash occurs a few minutes after the AI builds their fifth and final hatchery (Save for hatchery's in expansions). I've studied the script along that closely, however my scripter-in-training eyes can't locate the error.

Other then the crash, the AI works flawlessly. It still spams Hydralisks, however not in the large quantity as it once did.

Hmm well I've had a look and here are some things to consider checking,

-defensebuild_gg(2, Zerg Zergling) in --ZMCx 0000-- this command to my knowledge wasn't designed for repeated calls, could cause isses however is untested.

-evolution chamber upgrades look funny, 3 multiruns + upgrade calls in main, though I believe it shouldn't be an issue its hard to see what it will do just looking at the script.

-in block1 should consider replacing "expand(5, ZMCx 0000)" with "expand(99, ZMCx 0000)". To my knowledge only the 99 version of expand was really designed to be called multiple times. (The other ones can be called multiple times as well but they don't produce more expands, just maintain that number. Also their behaviour is questionable, particularly for numbers >3)

-defensebuild_gg(1, Zerg Zergling) in block1 same concern as first point.

I removed those and changed that, but to no avail; The mod still crashes.

After closer examination, I've noticed that the crash actually occurs a few minutes after the AI upgrades Zerg Carapace level 2. I'm positive it's around there.

I'll keep looking.

I added in build statements for tech buildings so I could run the script in a normal game using the BWAILauncher.

I found that a crash resulted on the replay AIvsAI ZvZ Tenago.rep at 15:32 game time.

It generates an "Instruction referenced memory that could not be read" terminal error.

This crash was found to be generated by the multirun block --dronebuild--.

By disabling the repetition of this block by replacing "goto(dronebuild)" with "stop()" the script no longer crashed and the two zerg battle it out till about 27:37 game time at which point one of them wins.

These are the files used in this test,
[spoiler]Original script with tech buildings added:
(found to crash on AIvsAI ZvZ Tenago.rep)
[attachment=2691:originalWithTech.txt]

Modified script
(same as originalWithTech.txt except "goto(dronebuild)" replaced with "stop()" and no longer crashes)
[attachment=2692:modifiedWithTech.txt]

Replay used for test:
[attachment=2693:AIvsAI_ZvZ_Tenago.rep][/spoiler]

Yay! It doesn't crash anymore!

Thank you for the help, I probably never would have found it out on my own
