MapHacker is a command line tool which can
list sprites from maps and their coordinates
patch maphacks into maps
check maphacks for duplicate or out-of-range entries
diff maps and create/update maphacks from the diff (so you can adjust angles directly in Mapster32)
1) Install it
MapHacker is a Perl program, so you need to install Perl. I suggest ActivePerl. Maphacker is not tested under Linux and will probably fail due to the case sensitive file system.
Make a folder in your Duke folder and add:
your maps (you have to extract them from the GRP, I used Roma Loom's GRPViewer)
NAMES.H from the EDuke32 zip
Maphacker.cmd from maphacker1.0.zip
2) List sprites and build patchmaps
Now run it. Open a command window, cd to your MapHacker folder and type:
maphacker maps 603,1294,1323,1334
It should print no messages. When it is finished, there is a new subfolder “hackmaps”, and a new file “spritelist.txt”.
The spritelist lists all maps which contain the sprites you entered, the positions of the sprites, and their names (if available in names.h). The hackmaps folder has copies of these maps in it. If you open one of them in Mapster 32, you will find that the sprites are already rotated like they are in the game with maphacks applied. That’s because MapHacker patched the Hacks into the maps by rotating the sprites by their hack offset. (Maphacker applied ALL hacks, not just the hacks for the sprites you entered).
To get a complete sprite reference, type
maphacker maps all
You will get an error message if the hackmaps dir is already present, so delete it first. MapHacker won’t overwrite your (maybe already patched !) maps.
3) Fix angles
Open the patched maps (not the original ones !) in Mapster32. Navigate to the sprites in your list using the coordinates:
hit esc for loading
zoom out using the mouse wheel
press shift to get a coordinate cross
right click when you’re close enough
switch to 3D mode with Enter (on the numpad)
you can move around with cursor keys
move mouse curse on sprite and rotate it with “,” and “.” (shift for fine adjustment)
hit esc and save it
(that’s Mapster 4 dummies, like myself :-) )
4) Update Hacks
and Maphacker will compare all maps in the hackmaps dir with the originals, calculate the differences between the sprite angles, and update your maphack files by these values.
