PiD Item Specs

Ron Hunsinger <listreply1@erstesoft.com> in a Story forum post writes:

The following is a reformatted dump of the internal table that PiD uses to describe item types. The data does not appear in any resources or saved files; it had to be extracted from the data initialization code of the 68K version of PiD (version 2.0).

The formatting will almost certainly come out wrong here. Sorry about that. I did try to add enough punctuation that the lines can still be uniquely parsed, with some extra characters to make it easier to identify the fields even though they don't line up.

The first two columns are just labels (item # and an abbreviated item name). The remaining columns are:

Frame: which image from resource '.256'(128). There is no palette adjustment, since items by definition can be picked up and carried between different levels, which would be using different palettes.

Usage: Each item has its own specific usage, but they fall into groups that have many behaviors in common. (For example, all weapons are different, but they behave alike in that they can be wielded and produce similar messages when you pick them up and put them down.) Internally, the game assigns a "usage number", from 0 to 9, to each item. Each group has specific messages that are displayed when you begin to use one, append to the inventory line while the item is "in use", or displayed when you stop using them. For some groups, the only difference in how they act is that these messages are different. I've arbitrarily picked mnemonic names for these groups:

Usage=0 (nouse): You can't use these items. Double-clicking on such an item in your inventory produces the message "You don't seem to be able to do anything with the ^1." (An unusable item may still be useful. For example, you can open/close the Canvas Bag, and put stuff in it, but you can't "use" it.)

Usage=1 (???): Behaves just like "nouse", but its volume is variable. PiD does not have any items with this usage.

Usage=2 (consume): When you double-click on such an item to "use" it, something unique to the item happens, and then the item is removed from your inventory. Potions and the Easter Egg have this usage.

Usage=3 (weapon): To use a weapon, it must not be in a container, and if it needs ammo you must have some. Your current weapon is put away, and this weapon (if different from what was your current weapon) becomes current. The begin/during/after messages are "ready", "(in hand)", "put away".

Usage=4 (crystal): To use a crystal, it must not be in a container. Your current crystal is put away, and this one (if different) is wielded. The messages are "ready", "(ready)", "put away".

Usage=5 (instant): Using this type of item does something, but the item itself is unaffected and remains in your inventory. Any messages are unique to the item.

Usage=6 (light): To use a light, it must not be in a container. Using a light toggles its "in use" flag, and also toggles a related flag the program can examine without having to search your inventory. The messages are "turned on", "(on)", "turned off".

Usage=7 (wear): Same as usage 6, except the messages are "worn", "(worn)", "removed".

Usage=8 (watch): Same as usage 6, except the messages are "worn", "(on wrist)", "removed".

Usage=9 (???): Same as usage 6, except the messages are "worn", "", "removed". There are no items in PiD with this usage.

The next column is the number of points (gold stars, hence the asterisk) you earn the first time you pick one of these items up.

Then there's the weight of the item, nominally in ounces, but the actual unit is 1/28th of a Kilogram. There will be some rounding error when these weights are converted to decimal for display. Weight is tracked but ignored in PiD.

The next column is the "volume" of the item. Volume determines how many things you can put in a container. The combined volume of all items in a container cannot exceed the container's capacity.

The $value is the value of the item. (Multiply the values in the table by 100. The unit is $0.1K.)

The final column combines two attributes of a container. Each item has a capacity, which is the maximum combined total of all items you put in the container. An item with a capacity of 0 is not a container. The other attribute controls what types of items can go into the container. A non-negative value means only that specific item can go in the container. (For example, the P4 pistol can only contain P4 ammo.) Negative values are wild-cards: -1 matches anything, -5 matches any kind of 40mm ammo, -6 matches any kind of AK ammo. The final column combines these as "none" if the item isn't a container, or itemType(capacity) if it is.

Note that the table says the Cedar Box can contain anything. There's a separate table specifically for the Cedar Box that limits it to holding only these items: Flashlight, Knife, WeaponP4, AmmoP4, AmmoMP, AmmoAKPlain, AmmoAKHE, AmmoAKSabot, AmmoM16, AmmoColt, Ammo40HE, Ammo40Frag, Ammo40Proj, SilverMedal.

Note that many of the "junk" items (notes, pamphlets, etc.) have zero volume. You can add them freely to containers without using up any space. (But they still count toward the hard limit of 256 items in your inventory.)

The table contains a number of unused entries, with all values zeroed out, EXCEPT that they forgot to zero out the frame # for item 67. The corresponding image is a tiny irregularly shaped red something-or-other. The shape dumper programs show a number of similar-appearing unused images in an assortment of colors. Make of that what you will.

For those who don't like my re-formatting, here's the original unformatted hex dump of the table:
