Dune II editor with 1.07 support


Recommended Posts

I said a MISSION, as in the mission SCRIPT FILE. Why would that script change the mouse cursor pos at the start of the mission?

[BASIC]
LosePicture=LOSTVEHC.WSA
WinPicture=WIN2.WSA
BriefPicture=REPAIR.WSA
TimeOut=0
MapScale=0
CursorPos=795
TacticalPos=468

LoseFlags=1
WinFlags=3

Starting a mission doesn't affect the actual position of the mouse cursor in the game (I tested that), and it overall doesn't seem very useful to me, if it changes from the moment the player moves his mouse.

Yes, in the original missions it selects the player's Construction Yard, and also prevents it's buildup animation from being played (you can observe in some DuneX missions with a pre-placed player's base that structures that are not selected play the buildup animation right at the start of the mission).

next version will have a slightly modified layout, and will use multi-dimensional arrays for everything related to the main types list (units/structs/houses becomes [0,1,2]), which removes a ton of exceptions from the code and generally makes my life easier :D

Theoretically, this should make it easier to add even more types to the editor, but there's still one huge problem with that though... at this moment, to get the name of an item in the units/structures/houses list (eg. "Carryall", "Hi-Tech", "Ordos"), it actually has an array (1,1,0) which tells it which option from the options list for that type to use to get that string. So to get a unit name, it looks at option #1 for the units (=name reference) and uses the resulting string as name. The function used for this is exactly the same as the one used to draw the values in the second column of the options.

Basically, this means the name has to come from one of the unit's options, which means there's no support for types without a name reference tongue.png

Hey Nyerguds,

I was wondering if it would be possible to implement a feature in your editor where you can compare a given field value for all structures/units at the same time. I have attached a screenshot from a dinky BASIC program I wrote quite a while ago to give you an idea of what I mean. Basically, lets say you have an unknown field, rather than having to go through all the units/structures to see how the value changes, you can just display that one field for all structures/units on the screen at once. It makes it easier to see patterns etc.

Keep up the awesome work :)

Hmm... that shouldn't be too hard... but I'll have to think about how to adapt the interface for it.

I could just make it as second column in the units list... showing the hex value of whatever's currently selected in list #3. I could make it a standard feature for hexadecimal mode, even.

Though this still doesn't show all values at the same time... after all, the full list is longer than the screen (except for houses)

I could also do it as basic popup box like the editing or help boxes. I'll have to make sure it's big enough though... I already got a smart abbreviation method to shorten any string to 4 chars (this is used for the prerequisites), so I can use that for this too...

Problem is that I have to choose for either one scrolling list, or hardcoding a multiple-columns view, which limits support for possibly much larger type lists added in the future.

I tried getting your editor to work on linux, but when trying to run it, I get this:

Runtime error 218 at $0000000000401884

  $0000000000401884

  $000000000040207E

  $000000000040AF3C

  $000000000040B15B

  $0000000000400178

I don't know much about pascal at all (I only wanted to run the editor to better understand the source;p),

but I had to fix some warnings and errors to get it to build with fpc, so I'll attach the resulting patch

at least...

What I specifically wanted to figure out was the version detection:

    dunever:  array[0..4] of string[7] = ('DEMO','1.00','1.07-US','1.07-EU','1.07-HS');

    //place of the identification string (gamenamestr) in each version

    verAddress:array[0..4] of longint = (225278,229282,228274,229682,229586);

    // Correction to make file addresses out of exe references for each version

    refAddress:array[0..4] of fourbyte = (($32, $4D, $90, $F0),

                                          ($33, $2B, $81, $10),

                                          ($32, $EC, $85, $00),

                                          ($33, $44, $7F, $80),

                                          ($33, $3E, $7F, $E0));

I was thinking that refAddres found at the offset verAddres might be what identified the version,

but I couldn't make much sense to that..

Any hints? :)

well, you have to make sure to understand that these rows of 8 bits (datatype 12-19 in my editor) are all read from one single byte... if you look at the getDataLen function in my code you see the length of each entry type in the list. The bits are done so only the last of the 8 options actually has size "1". The first 7 all have size 0, making the editor read these 8 options from that one same byte before continuing to the next.

So I guess that part is wrong in your structs there. These 8 options together are really only one byte each time. In your structs it are 8 bytes.

oh, never mind, I figured it out when I looked closer into the 4 byte data I actually found at those offsets. :)

"verAddress" is just the offset of the exe filename string (normally "dune2.exe", but can be modified) in each version. "refAddress" is unrelated to that; it's used to get the string address from a string reference in the editing data. "dunever" is just the string to show in the editor; it has no relation to the actual identification process.

As for getting it working in Linux, I use FreePascal (from the Dev-Pascal suite), which, unlike normal pascal, allows functions that return custom defined datatypes. All internal traffic in my editor uses these FourBytes. Though this was mostly done because I didn't know I could use bit shifting and AND/OR functions to easily get separate bytes from a larger 4-byte value. Heck, I still haven't figured out if there's an actual unsigned integer type in Pascal. Hence why I used bytes :P

Ah... honestly, I don't have a clue how that works. There doesn't seem to be any indication of when the next actual byte in the struct starts, using that bit indication system... unless the format actually requires you to define all 8 bits.

yeah, but notice the ':' at the end of the declarations, 'uint8_t foo:1' refers to the first bit, 'uint8_t foo:2' the second, etcetc. :)

That doesn't sound right. It's the bit count. So :2 is 2 bits. Layout is undefined by C++ (compiler depended).

EDIT: Forgot to mention, the bitfields were most likely done using ENUMs, the IDA DB has them mapped out if u just wanna copy/paste (nothing fancy ever happens with the OptsWoca fields, etc) the data is never copied from the internal hardcoded structures... tests are done directly against them

yeah, you're right, I'm mixing things, but doing like segra suggested as in Dune 2 will probably be my way to go anyways. :)

nyerguds, I was talking about data structures, not buildings ;)

segra: cool, but how many entries for filedata & actiondata?

Also, do you have any example code making use of these structures?

Any updates on your emc code would also be welcome btw. :)

thx!

action table is 14 entries

file table is 671 entries, terminated with a null entry

havnt worked with the action table yet so im not sure of what its for

filetable however is checked if opening of a file from the disk fails, it searches for "filename" in the table, reads the "parent index" field (which is the index of a pak file), and attempts to read "filename" from the pak

gonna do some decoding of those unit script functions again in a few days, so will see what can be done ;)
