半条命2mod使用方法以及出错解决方案
1、打开游戏目录，并把mod文件夹直接放入里面
2、在游戏目录里找到hl2.exe,并右键点击然后点属性创建快捷方式
3、右键点击快捷方式，再点属性。在目标一栏的最后面加上一段话：
-game 你mod的名字(注意大小写-game前面有空格)
4、然后就能用刚才的快捷方式直接进mod了！如果出错请看下面
1、在Mod文件夹找到maps文件夹并打开，里面找到background_01.bsp
可以删除也可以改下名字（删除记得备份一个）
2、这个解决办法我转载了Steam社区一位老司机的一个方案
将以下代码复制到并替换原来的gameinfo
HL2 -» "SteamApps\common\Half-Life 2\hl2\gameinfo.txt"EP2 -» "SteamApps\common\Half-Life 2\ep2\gameinfo.txt"
代码：(半条命2的mod):"GameInfo"{ name "mod名字" game "mod名字" title "mod名字" title2 "" type singleplayer_only icon "resource\icon" homepage "" developer "" FileSystem { SteamAppId 220 SearchPaths { game_lv hl2/hl2_lv.vpk game+mod hl2/hl2_sound_vo_english.vpk game+mod hl2/hl2_pak.vpk game |all_source_engine_paths|hl2/hl2_textures.vpk game |all_source_engine_paths|hl2/hl2_sound_misc.vpk game |all_source_engine_paths|hl2/hl2_misc.vpk platform |all_source_engine_paths|platform/platform_misc.vpk mod+mod_write+default_write_path |gameinfo_path|.. game+game_write hl2 gamebin hl2/bin game |all_source_engine_paths|hl2 platform |all_source_engine_paths|platform } }}
