How to backup map?

Why would it be acceptable here when it is considered a GAT (Game Altering Technique?)

Explain.

If you use the -seed command you're a hack and deserve all the ridicule you get. Nuff' said.

Correct me if I'm wrong but I believe I have seen previous threads on "-seed" in the SPF, and the general consensus was that you can use "-seed" to change the map, as long as you quit d2 and took out the "-seed" after you got the correct map on. That way you don't exploit the messing up of the randomness...

Last time I knew the -seed command was not allowed if it's allowed then why not allow -act5? Or the -BOTD one as well ;)

There have been multiple discussions, theories showing that seed does affect drops or doesn't...

Personally, I do not see what is right about it.
 
You are correct that keeping "-seed" after the line while running that does affect drops...

HOWEVER, when you change the map, and then remove seed and reload diablo 2... does it not remove the parts where it affected drops?

this is highly unlikely. it's more a myth like "cell phones on airplanes are dangerous" The seed # is only part of the random number calculation used by a complex game like D2. Mostly likely, the seed # is combined with something like the computer clock, to generate a truly random number. to accomplish what you say, you'd have to use the same seed # and go back in time and start playing at the exact same millisecond.

The truth is, the seed command doesn't affect drops. at all. ever.

Such confidence AnonPoster? Seems a little rude to state it like what your saying is fact with out you testing or having some sort of documentation or discussion to reference.

So I decided to take the empirical approach.

Test Process:

Setup:
Find a wp with a prop(s) close by.
Once found, save that map seed and close D2.
Then change the command line to include the -seed command.
Start D2.

Process:
Choose char and difficulty.
Run directly to town wp and then choose waypoint.
Pop all props that are close by in the same order and following the same path.
Screenshot.
Collect items for fingerprint analysis later on.
Save and exit game.
Start the process again.

Results:

These are my main examples. More are available upon request.

Conclusion:
Keeping the -seed command in the command line WILL give you the same drops assuming you do not alter the seed by changing path's or other. (Note: I'm unsure of all actions that will change the drop) You WILL get the same item type and fingerprint if you there is no change in the seed. It is not a good idea to run with the map seed active.

Some items of interest:

Was interesting trying this. Before this run I had found three items of the same type and fingerprint, but it was normal item so I wanted to make sure that if the item were magical or whatnot that it would still roll the same. Luckily I was able to get the set item to pop up.

Known actions that change the drop:
You need to stay on the same path to get the same drop.
Using atma (with autosave on) changes what drops.
Dropping an item from your inventory changes your drops for that run. However if you drop an item each time you run, you get the same drops.

This was from a time when this was being discussed "around". This was in 1.10.

From SPF Stick "Gameplay affecting techniques" said:
However, it also allows for the recovery of maps if a player accidentally changes difficulties or joins a multiplayer game. The consensus of the SPF is that the -seed command can be used to recover a map. However, once the map is recovered, the player should exit the game, clear "-seed" from the command line, and return to playing as this prevents abuse. Under no circumstances should map seeds be shared with other forum members. You should be up front about your use of this command when seeking to trade as well.

This pretty much says what I mentioned earlier.

Everyone doesn't have to agree with it, but this is the current view on the seed command at the SPF. Until we complain or the mods or admins change it.
 
Nice investigation, Chase. It's fun to see evidence about this. Personally, I don't like the -seed command. It has too many weird consequences, and I don't like to mess with it. I don't think it is "cheating" but just like anything else, be honest about using it...
 
I have a question Chase.. you said you ran it while "-seed" was still there correct? Did you try changing the map, then quitting D2 then removing "-seed" from the startup line and restarting D2?

I know that "-seed" being there does affect item drops (its always been said that it does), but I'm really wondering about does the changing of map THEN reentering it. If that does affect the drops.. it woul dbe interesting to find out if its for one run, or maybe for all? That way this can be settled slightly.

I'll probably try it myself.. soon.

That is a good question! I should have done it as a control for my experiment. :eek:

I just did about 5 runs using the same technique as before and I found that not even the props are the same each run. (Slightly different location or type, and sometimes not even there) I also didn't find any pattern in the prop drops. (not even base item type...much less a dupe) Although, it still should warrent some further testing. I hope you give it a try Bull(R).


edit:I didn't use the -seed command and then quit the game and then remove seed command and restart. I felt it was equivical to starting up a game with a char with a explored map and then running the props. I'm rather confident this would be the equivilant of doing the above. Although you should give it a shot.
 
I will, right now my brother needs the computer and I have a really good countess map... so I don't want to play around and find using -seed to get back this map would affect drops and I couldn't do it.

I'll probably try sometime tomorrow.. doing 5 or so runs with -seed there
and 5 or so with -seed gone, we'll see.
 
Well I have proceeded to do my "test".

The initial results were the same as chase, I found a WP near the black marsh area... went to ATMA to get the mapseed... and then added "-seed" to the game.

My first run I got this:
Amulet of the Colossus
Required Level: 22
Item Version: 1.10 Expansion
Item Level: 38
Fingerprint: 0xf9b33644
+49 to Life

Which yes, I did ID in game (to see if that would affect anything). I kept the amulet for the next run in which I recieved 137 gold. I thought this was wierd, shouldn't seed have screwed with the drops?

I decided to mule that amulet to a character in atma (who I now deleted) to see if not holding onto the item would make a difference. Reran this map again and low and behold:
Amulet of the Colossus
Required Level: 22
Unidentified
Item Version: 1.10 Expansion
Item Level: 38
Fingerprint: 0xf9b33644
+49 to Life

I didn't Identify this one, but its the exact same item (with fingerprint). Okay, so did this mean as long as you held the item you couldn't get that same drop again?

Reran it around 10 times in a row while in possession of the amulet and recieved: 137 gold, 137 gold, 137 gold, 137 gold, you get my point. I never touched the gold, as I didn't want to fiddle with my experiment. I then proceeded to pick up the 137 gold (which I dropped after the test was completed) and reran, seeing if having this gold in my possession would alter the drop in the same way that having the amulet did.

NOPE. Next run recieved another 137 gold. But then again, gold does not have a fingerprint.. so maybe the game checks for the item fingerprint and then only drops that same item if it doesn't already exist in game (makes sense).

Then it was on to what I was wondering, now running the same map; same everything.. but removing "-seed" and restarting the program. Next run I entered after starting D2 up normally went like this:
Walked to WP
Took it to Black Marsh
Walked to where the stone was..
Saw there was no stone.

So I had just removed seed and the stone dissapeared... I ran it three more times and all of the chests/stones/etc moved each of these times.

What did I learn?
- Keeping "-seed" in the startup line DOES affect drops.
- If you possess an item, the game will not drop the same item in the game, even if "-seed" is still there.
- Once you remove "-seed" the drops aren't affected as the chests move like normal.

So I hope this helps people in believing what I've said all along:
You can change your map, if you do use "-seed" however... CLOSE DIABLO 2 and REMOVE "-seed" BEFORE running. Then restart Diablo 2 as usual, and from what it seems drops aren't affected!
