Right now i'm trying to figure out the randomly spawning guards on Surface. I went through some of the code using the Goldeneye Setup Editor and while it's extremely difficult to follow what's happening i could make out a rough algorithm:
(There are 4 spawning guards and each of them runs this code seperately)
1. Start cycle counter
2. If cycle counter > 120 continue else wait (simply wait 2 seconds)
3. Reset cycle counter
4. If cycle counter > 120 continue else wait (wait 2 seconds again, the game checks some objective bits during this)
5. Seed random Byte (I want to know this byte)
6. If Seeded byte > 200 continue (So i can know if this is true or false)
7. If Seeded byte > 50 continue (Dunno why they do this, should always be true since value is already determined to be bigger than 200??)8. Spawn Guard
This code determines WHEN one of the 4 guards spawn. When that happens, the game simply checks which "room" Bond is in, and has 4 pre-determined spawn locations for each room, i.e one location for each of the 4 guards. But since the guards spawn at diffrent times, they can still end up in seemingly random locations.
In my 1:44 run, Guard #4 spawned by the houses where the alarm and camera is, and this can only happen if Bond is located near the grenade launcher hut when 4th guard spawns.
Here's the code in it's original form:

Anyway, i guess this is jibber-jabber for most poeple. My point is that the RNG which seeds the bytes could be very useful to understand. Not only for this level but for all levels.
Edit: I found the addresses of the 4 guards timers!
Edit2: Seems like these addresses are not static, so the addresses will be diffrent each time you play. Should be easy to find though since after you've gotten a bit into the level they start to continously count to 120 and then reset. Over and over and over...
Locking these values to 0(or sub 120) will hinder the guards from spawning completely. Would be great for DLTK lol if it was allowed. I guess this is a good step forward since we now know when their timers start(it's not immediately), and when the random seeding occurs. I'll continue investigating this..
These WIPs are insane. I can't believe you're actually saving time WITHOUT lookdown. Seriously, great job. I think on levels like Surface, if it's super laggy no matter what, then you should use lookdown there. Like, only do it if it makes a significant difference.
Thanks.
I honestly don't think lookdown makes as much diffrence as we thought. Surface will give a definite answer but i'd be suprised if i loose alot considering i've lost nothing so far.
--------------------------------------------------------------------------------------------
The guards timers on surface appareantly don't start until you enter one of these rooms:
So no random guards until then. Could be useful for DLTK since you can get the large key and second key(by luring the large key guard through window, like the TAS'es) before a single guard comes out. Also you can control their spawn locations by remaining in a single room for a while. It should be easy to get to safe too before any guards have spawned and are close enough to kill Bond.
Edit: Above statement is wrong, this provides no help for DLTK simply because 007 mode works diffrently than 00A(besides the guard settings). If you start up surface on 00A and just wait, no guards will come, ever. But on 007 they will appear. So on 007 their spawning works diffrently for some reason.
I wonder if there are any other fundamental diffrences between 007 and 00A?

I've always thought it's because in DLTK we set their reaction speed to 100%.
Seems like you're doing a good job figuring out how the guards work.

Nope, even with normal 00A settings they spawn immediately. Also tested with reaction speed 0%.
Seems like you're doing a good job figuring out how the guards work.
Yeah i know pretty much everything about how they work but without the randomly seeded numbers i don't stand much chance manipulating them(except trial and error method which i'm trying to avoid).
I wonder if there are any other fundamental diffrences between 007 and 00A?
This is probably well known, but there are several levels where body armor exists on 00, but not on 007. Iirc, these are:
Silo
Statue
Jungle (second armor)
Beyond that, I had never heard any other differences before. Really interesting research, Henrik! Encourages me to spend more time in GE Setup Editor and see if I can find any more differences.
Yeah you can really learn alot from the GE Setup Editor, and also memory watching although that's much harder. I also realized that the GE hacking community has already identified tons of memory addresses(although it seems to be diffrent then the emulated memory...) and figured out alot of the game's mechanics.
About RNG's, i've been trying for a while now to find the seeded values but without luck. When you don't know exactly when a value is seeded or for how long it remains unchanged or even how it behaves, how the hell do you find it? RNG's have been found for pretty much every RPG ever and lots of other games and i assume there must be similar issues there?? Surely there must be some general approach to this?
Alright, i made a post over at shootersforever forums and they knew precisely where i could find the random seeds. So after some converting to anti-ds mupen's address space:
008F0EF4
008F0EF6
(Unsigned short)
These can be read as a single double word or seperately. Locking these values can produce some cool effects such as guards throwing grenades over and over and over.

(too lazy to test it myself + more a suggestion than a question)
Does shooting affect the RNG? (each shot has an inaccuracy-offset.... but is that based on an RNG or just a preset pattern? :))
008F0EF4
008F0EF6
(Unsigned short)
These can be read as a single double word or seperately. Locking these values can produce some cool effects such as guards throwing grenades over and over and over.
I just see values that move around when I look at those addresses. How would you use them to get a grenade? Does it have to be some specific value? I would probably need some guard position addresses too... this feels a bit above my head, but it's great you found them so you can make use of them.
Presumably the guards have a list of behaviors they can choose from randomly, based on the RNG value. E.g. 0-10: crouch and shoot; 11-20: stand and shoot; 21-30: run to the side; 31-40: gun jams; 41-50: throw grenade, etc. So you have to get the RNG to the right value at the time the guard is choosing his behavior (obviously he's not choosing a new behavior every frame) if you want him to throw a grenade.
Probably the best way to figure this out is to manually set the RNG value and observe how the guards behave. For example, if you fix the RNG to 0, then the guards should always do the same action, assuming that the random number is the only input on their behavior. Actually behavior probably depends also on the guard's position with respect to the player (for example, IIRC guards never shoot unless they're on the same horizontal plane as the player), but at least for a given RNG value and situation the guard should always do the same thing. Anyway, once you've determined the values you need you can go about figuring how to achieve them without cheating.
Pyrel - an open-source rewrite of the Angband roguelike game in Python.
Well obviously they move around since they are randomly generated numbers. When for example a guard decides what action to use, they grab the first byte from one of the addresses and then compares it to some pre-determined values. So for example if a guard is gonna pull a nade, the byte must be a number between 0 and 10. 11-50 means sidestep etc...
Edit: yeah what Derakon said pretty much ^^ The Ge Setup editor can reveal exactly what numbers are needed for certain actions.
Probably the best way to figure this out is to manually set the RNG value and observe how the guards behave. For example, if you fix the RNG to 0, then the guards should always do the same action, assuming that the random number is the only input on their behavior.
This is precisely what i did and when locking the value to 0 every guard who can throw a nade will always do so, no exceptions.

Finally!! This has taken longer because i can only work on weekends now but still a crazy amount of work put into this. I was forced to use lookdown for a very brief moment when entering the safe hut because lag was crazy there and i would've lost tons of time. Otherwise this was pretty much perfect.
Bunker is gonna be a nice vacation now...

Heh very smooth :D Seems that you took much more care in preserving 'fast-run' :)
Did you happen to play around with the juggle-the-key-out-of-the-hut idea? :D
I think the Large key is what opens the safe hut so juggling the key is useless. Also me and Simon tested it during last run so i'm pretty sure it's impossible(some keys can only travel up/down, not sure if that was the case here)
Bunker 1 Finished
Time: 54.7
Time is identical to my last run though i used the slower start to save real-time. 53 or low 54 might be possible with cinema watching, i found a few places where my old run lost time.

Edit: LOL i found my old files from last run and it appears that my rerecord count back then was nothing compared to now. I've used 40k more already :P
I can't download your bunker because I get a virus warning from that site. you could upload it here instead: http://dehacked.2y.net/microstorage.php
i made a ge tas too, i'll upload it today maybe , i found a small possible time saver u might not know.
i would rather see u go for ingame time
