(TagMetaOffset + ValueOffset) -/+ PrimaryMagicThe offset in the tag index is the address to it's tag data in memory. The "magic" values are used to find the offset in the file.grimdoomer wrote:I don't think I understand. Are you saying that I read the value in the map, and that is the memory address?
So I should goto the tags RawOffset + valueoffset?LuxuriousMeat wrote:The offset in the tag index is the address to it's tag data in memory.

but yeah, back in 05 I think it was, I worked on a C++ codebase for dealing with halo 2 maps and other related data on the PC but by designing the implementation after how the game deals with content and memory so in the end I'm just loading the map into the base address and saving me hours of extra work writing fixup code and processor power running that code.
