I'm new to this forum and not quite sure where to post this question. So please, if anyone would like to move it to a more decent place...
After my "Sacred 2 Gold" with "Ice & Blood" expansion has slept for a few years on my hdd I decided to revive it a bit. I'm not only playing a new character from scratch, I explored the files in the game directory as well. And there I found the PoiData.txt.
Those files doesn't seem to be documented very well. At least I found no source via Google. A few pages list the files and maybe even describe the intention of it, but I found nothing about the technical details of them.
I coded a program in VB.Net to load a map image (I found one large 12000x12000 jpg somewhere) and import the PoiData.txt. A bit scaling (actual test at 2000x2000) and I got a result that looks not that bad, but quite not correct, either.
I tried to use the ScreenX and ScreenY directly and draw circles with 20px diameter. Most of the markers are a bit off course, but not that far away from reality. Interestingly enough the markers are left and right, above and below the wanted position.
So I think I have to use the Offx / OffY and maybe the WidX / WidY, too.
I scaled the circle by 1250*WidX and 750*WidY and now for example the Thylysium marker almost exactly covers the city on the map. Some other markers seem to sit correct now, too. But others still are a bit off.
And I have no idea how to use the OffX / OffY information.
Can anybody help me with that? Or is there already a documentation for it?
