I am just about to believe this statement. How many presents on average do you need to open to get a snowglobe in a pre-wall world?

Don't know if this matters in the %s, but one of those snow globes was pre-wall, the other two post-wall.

On the other hand, the Wiki says that snowglobes only drop in hardmode.

[Darvi]

the Wiki says

That should tell you all there is to say on the matter.

[AlStar]

Hmm, I'd swear that I got one of them before I defeated the wall.

But if the Wiki says they're only available in hardmode, then maybe I'm misremembering things.

Nice to see that I got the drop % just about right though.

[The Merchant Of Menace]

The wiki may be, and probably is, wrong. It's user edited after all.

[Girlinhat]

I spent a few nights grinding zombies in my "run this dungeon" world, and got no snowglobe.  I'll readily believe that it's hardmode only, perhaps when opened in hardmode, though.

[Metalax]

Yes, it was corrected last night but someone has changed it back to being incorrect. Globes do drop on pre-wall worlds but with a lower chance.

[Shadowlord]

I stopped playing since 1.1.1 made all my housing invalid, personally (apparently it's the doors being open).

[Metalax]

Is your housing at or close to the minimum size? I kept having problems with it going invalid when doors were left open when I was using a minimum size layout, which may be the case here.

[eerr]

I spent a few nights grinding zombies in my "run this dungeon" world, and got no snowglobe.  I'll readily believe that it's hardmode only, perhaps when opened in hardmode, though.

It appears to me as either really random, diff chance per harder monster, or per monster killed X times.

I farmed the dungeon for bones and got like jack shit for snowglobes.

one?
I ran out of space before it dropped.

Go farm unicorns or corruption for presents and you might have better luck.

Best bet might be hell in prewall.

[Girlinhat]

Just got my first globe, decided to fight it out on top of my base (which is underground like a proper dwarven base).  I hope I get more snowglobes from the presents dropped by these snowmen

[0x517A5D]

The Wiki is correct.

If the present is opened in a hardmode world, there is a 1 in 14 chance of getting a snow globe.

It's purely random, it does not depend on monster strength or how many monsters you've killed.

I just verified this by disassembling the executable.

    ldc.i4.s 14                         // get a random number between 0 and 14-1.
    callvirt int32 [mscorlib]System.Random::Next(int32)

    brfalse.s check_if_we_should_create_candy_cane_blocks // if not hard mode, skip to next section,
                                        // which will create candy cane blocks.

So grind in softcore if you want, but open them in hardmode.

[eerr]

I grind ages of presents in dungeon.

...

one snowglobe.

over 1k bricks.

sure there isn't more to it?

Probably.

Maybe.  I just repeated my scan for the snowglobe constant, and found what appears to be a second route for their creation.

Near the end of this snippet, a random number is generated.  One of the possible values is 0x25A, which is the constant for the snowglobe.  And that number is fed right into a subroutine named NewItem.  So it does appear to be a second route for generating snowglobes.

Among other tests, this snippet checks that the dying monster is of "type 0x79".  I interpret that to mean that only one type of monster can drop these particular snowglobes.  I don't know what that monster is, though.

Also, this snippet is only reached if the game is not in hardmode.  (I didn't show that test-and-branch in the snippet.)

Edit: Correction: the code tests that the monster type is not 0x79.  Monster type 0x79 cannot generate snowglobes.

Edit: Correction: cancel all of this.  This code does not generate snowglobes at all.  I just checked the definition of System.Random.Next:

Return Value
A 32-bit signed integer greater than or equal to minValue and less than maxValue; that is, the range of return values includes minValue but not MaxValue. If minValue equals maxValue, minValue is returned.

So this code generates numbers greater than or equal to 0x257, and less than 0x25A.  So the three possibilities are 0x257, 0x258, and 0x259.

This is just the present-dropping code.

[Trapezohedron]

Guess I was right after all. There are no snowglobes pre-wall. That should clear things up.

Time to initiate operation Merry Christmas pt.2.
