you appear to be missing a number of banners? (i.e. those which have automatic colouring)

http://www.ultimateamiga.com/HostedProjects/GamesCorner/TheCryptOfBloodwych/Maps/bw_keep_3.jpg

^^ look in th efirst main room after the recruitment area... there are various signs i have shown as 'white' which are generated at random (or rather, seeded "random"...)

here is my stone-wall code, which includes banners and gems etc.

like before, it probably uses some modulo functions where it would be better using bit-test functions... sorry about that!


to read about how switches are defined, see also here:
http://www.ultimateamiga.com/index.php/topic,8908.msg39953.html#msg39953
because the below code refers to a function which reads-in the relevant switch operation.

Good spot, missed that group off..



Also I'm looking into a new features which will let me support real time map editing in the Amiga/ST Versions when played on a emulator, also this will allow you to have a real time map which updates the player location

[MadMunky]

Real Time Player tracking is now working for Steem, I need to clean up the code and decide if I want to read all of the ST Memory so I can update the whole map (open/closed doors etc) then once this is all working nicely I'll add in a WinUAE option

[MadMunky]

I got real time tracking working with winaue also.

Horace any chance you want to share the source of your editor so I can try add all the same features as I can see any reason why I cant make my version support the same + Atari/PC support also

Had to add the option for winuae to rescan the memory as sometimes it will find the data in the HDD image not the live game

[MadMunky]

Not sure if you guys know this but the Level Data is always 5122 Bytes apart

So MOD0 + 5122 bytes = Serpent Tower Data

This is the same on Atari and Amiga

[MadMunky]

So live mapping is now working (read-only atm) but with the live data there is some different values have you seen these two before?

01 43
00 43

This is normally a Pillar/Bed but do you know what that 4 Means?

Also do you have any code for the different doors as I still need to fix this.

*UPDATE* Ah its cause there is items on the floor

[Hungry Horace]

i will upload the source for you when i get the chance

looking at map data as AB CD, in your example C = 4

bits are switched on/off in this value, to show what is 'occupying' the space. You will generally only see this when you look at 'live' data

this is entirely from memory, but i *think*....

bit 0 (usually C=1 ) is used for a door lock , bit 2 (C=4) you have just said is an object....   bit 3 (C=8) iirc is a person (monster or champion).... that leaves bit 1 (C=2) must be a spell in that location. e.g. a fireball that has been launched or similar.

obviously these can then also be combined if several of them are true!


what door code are you after? metal doors? i posted this already...

http://www.ultimateamiga.com/index.php/topic,8806.msg44182.html#msg44182

[MadMunky]

Cheers again Horace not sure how i missed the door code :s

Doors now working

[Hungry Horace]

as promised, attached is the editor source code. i cant be 100% it's the latest version, but it has all of the map code (converting to both text, and AMOS style draw commands) in it.

I'm not sure there is much 'extra' to learn from it... i did try to create a "standard" input/output file format that could potentially become cross-platform (the .map and .obj files that it creats be substituted directly into the PC version for example) ... however, when i tried to put my new levels into the ST version, it didnt want to run - this may be related to the ST versions copy protection though. 


to answer your other PM question MM, i have never created any remake of BW... i have some basic wall-drawing code for AMOS but i didnt write it, and it isnt very good tbh!! (for map/editing purposes your ST/UAE plugins are far better!!)

anyway, hope this helps, and sorry for the delay - kind of been busy of late!!

[MadMunky]

Thanks Horace, just taken a quick read though and its amazing how similar we have done things but I cant see any code about objects in the file which is what I was really after

Also did you have any of the graphics still like monster images/object images as all the ones I ripped where from the PC version so will need to redo them otherwise, any chance in your Bloodwych font saves me having to make it

I'll make sure your not reading any map data I've missed and then on that side we should be same, do you happen to know if the location of the Bloodwych data is different in different version of the Amiga disks/HDD version as I'll try add support to import/export as many formats as possible

[Hungry Horace]

there should be object code, because there is an object stack-editor and a way to place them.

they arent 'displayed' on the map though. i will check the most recent code for you later today if i can

there are definitely two different versions on the amiga, with different offsets for the data - i think they may have fixed a couple of bugs (like where some objects on the floor are displayed in front of the wrong things, like people's feet) .... not sure of the exact changes!!

i will also dig out the monster /character graphics for you, but the font was made by my brother, so i may have to simply 'draw' all of the font-characters onto an image file for you!!

[Hungry Horace]

ok, so it seems you were right - that code was quite out of date!

I have exported the code from the last version i had - you should find this more useful i hope!!


edit: all monsters / characters .gif attached also

edit 2: and now the font image thing .... although you may need a 'pure' output, this is just a screen grab from OSX... let me know if you need it 'clean'

Any chance you can open source your map viewer code?  Don't worry about clean up, everyone's code is a mess   It'd be another resource for the rest of us that might want to spend time bringing Bloodwyche out of the darkness.  I know I've tried disassembling it several times, but unfortunately given up.

shame - i'd love to see the Amiga Bloodwych fully disassembled and commented.... then we could start thinking about adding new functions, switches, objects, etc

i can dream!!

10 grand and I'll disassemble it and provide you with portable C source code.  Maybe even an Android port.  Too many other things to do, otherwise.
