bsp文件:BSP结构文件分析整理总结

on 2009-2-12 in 游戏开发 | 0 Comment


直都想把Hl2BSP文件给分析分析的前也尝试过很多次可直进展缓慢昨天又看了下个BSPLoad源码终于知道是个什么概念了…………
\"\"
头文件中包含:ＢＳＰ文件版本号等信息．


\"\"\" align=top>structdheader_t
...{
\"\"\" align=top>ident;
\"\"\" align=top>version;
\"\"\" align=top>lump_tlumps[HEADER_LUMPS];
\"\"\" align=top>mapRevision;//themap\'srevision(iteration,version)number(addedBSPVERSION6)
\"\"\" align=top>};

这个结构体包含以下信息:
ident BSP文件类型(idIBSP ValveVBSP)
version 版本信息
lump_t 数据块信息
mapRevision 地图修改信息

lump_t结构体如下:


\"\"\" align=top>structlump_t
...

{
\"\"\" align=top>fileofs,filelen;
\"\"\" align=top>version;//defaulttozero
\"\"\" align=top>charfourCC[4];//defaultto(char)0,(char)0,(char)0,(char)0
\"\"\" align=top>};

fileofs 偏移位置也就是在文件中起始位置
filelen 长度
version 版本
fourCC[4] ４位…………没有太明白它含义读取出来都是０
