Boulder Dash Forum

OK, this time, I make sure to ask a question the correct answer of which doesn't overstrain myself )

In total, how many levels are there in BD1&2 where you cannot collect any bonus diamonds? (Intermissions do count; every difficulty level counts seperately.)

65.

I come to a different number. Perhaps you make a list of your levels that I can compare with mine.

Correction: 70
My list here:

BD1 all levels:
C
D
Q
R
K
L
S
T

BD1 single levels
B/3
E/5
F/4
F/5

BD2 all levels:
Q
L
S
N
T

BD2 single levels:
G/3

You actually can collect worthless (ie, value = 0) extra diamonds in:
BD2 R
BD2 O

Q, R, S, T are the intermissions.
I hope, I didn't have overseen anything.

Yepp, 70 is correct!
BTW, the bonus value in BD2, O is not zero but 10 (just as the initial value)!

Your turn now.

In the BD1 engine, you have a cave with amoeba somewhere in the top part, a magic wall in the center part and more amoeba in the bottom part. A boulder is falling into the magic wall right at the beginning and activates it. Milling time is set to 1 second. The rest of the cave may be anything you like.

How can you convert the amoeba into diamonds without enclosing all amoeba pieces (yes, BadDog73's suggestion does count as enclosing) and without destroying the amoeba part above the magic wall?

Can't you simply enclose only the amoeba at the top with walls?

When the boulder falls into the magic wall, the cavescan restarts, and the growing spaces for the bottom amoeba are not counted by the engine. This way the top part is not destroyed, and not all amoeba is enclosed.

Exactly. Your turn.

A combined question this time:

Which elements from the BD1 engine are not (visibly) used for Random Fill in BD1? The same question for Object commands.
What are the changes w.r.t. the used elements in BD2 and BD3?

(Initial fill and the border placement do not count; also birth/explotion stages and different states or directions of the same element do not count.)

Here's my list:

BD1: not used in randfill:dirt*, magicwall, butterfly, amoeba, steelwall, inbox, outbox
not used as object: steelwall
BD2: not used in RF:dirt*,wall, magicwall**, butterfly, amoeba, inbox, outbox, steelwall, slime, expwall
not as object: none
BD3: not used as RF: steelwall, dirt*, wall, butterfly, amoeba, inbox, outbox
not as object: dirt***, steelwall

I only mentioned the items that actually occured in the particular games.
Remarks:
*Of course dirt was randomly set in many caves, but as far as I know, it was the initial fill element every time in which the other elements were filled.
** In cave K, there are randomly set magic walls, but they are actually an object (the "add"- object)
*** There are caves where dirt is a regular element, but it is always the initial fill element.

Hope I've not forgotten anythiong!

EDIT: correction: In BD3, dirt WAS used as object in the ints, with space as initial fill!

Almost correct... One element is missing in each list. And in one of the random fill lists there's an element too much.

Two remarks:
- It's not "random" by means of an 'Add=' object.
- It's not dirt or the space element. Because the initial fill is usually one of these two, I don't bother whether they count as "visible" in the random fill.

OOPS!! Of course random amoeba WAS used in BD2, cave B! I'm still thinking about the missing element/s...

In BD3, there's missing "falling boulder" as regular object and "diamond birth" as randfill. (But as you said, these should not count.)

In the other lists (BD1&2) I can't find anything missing. The following elements were used:
BD1: dirt, space, boulder, diamond, inbox, outbox, firefly, butterfly, wall, magicwall, steelwall, amoeba (have I forgotten any??)

These objects were all used in RF respectively as objects- except the ones I listed up. I can give examples for every element.

In BD2, slime and growingwall were added. Again, I cannot find anything missing. Am I silly now??

Explodable Steelwall?
