Resources
src: https://git.runewiki.org/Old_Engine/WorldMap
jar: https://runewiki.org/archive/worldmap/WorldMap-1.0.jar
data: https://runewiki.org/archive/worldmap/3xx-worldmap.jag
Functions
Click and drag the mouse to pan around the map.
Press "E" to export an image of the full worldmap. In the original source, it was saved as a raw RGB image and the image dimensions was in the file name. If you use my fork it will be exported to PNG for you.
Loading Data
Initially the client will try to read worldmap.dat from the cache directory (e.g. C:\.file_store_32). It will check the SHA signature of the file against Signature.sha saved in the applet code.
If that fails, the client attempts to load the latest worldmap.jag archive. If the applet is running as a frame it will load it locally from the working directory as "worldmap.jag." Otherwise, it will download from an HTTP server (the codebase of the applet or localhost). It will only download up to Signature.len bytes and must be changed if there is a data update.
When downloading remotely the URL it loads is "worldmap" + sha + ".jag", where sha is half of the SHA signature represented as bytes, and concatenated:
for (int i = 0; i < 10; i++) {
sha = sha + Signature.sha[k];
}
worldmap.jag Files
worldmap.jag is a BZip2 archive like the ones stored in main_file_cache.idx0.
The files it has inside are:
- size.dat
- labels.dat
- floorcol.dat
- underlay.dat
- overlay.dat
- loc.dat
- mapscene
- mapfunction
- b12_full
- index.dat
Some of these files are already available in the game cache.
