插件中的这一句不明白，register_forward是干什么的

normen2

register_forward(FM_Touch, "forward_touch")
转发？

Rulzy

forward在这个地方我也不知道怎么翻译比较好，有向前、转发的意思。这个函数的作用是注册一个forward，比如你说的例子，当发生Touch（接触）事件时，就会执行forward_touch函数。比如，你可以在此函数中，判断玩家是否接触到掉到地上的枪。

Ryu2877

于fakemeta模块中，

其他的语言没学不清楚，不过在PAWN中，个人习惯理解为“转寄”；

具体意义在于：

某一个功能模块（HL引擎或其他mod dll中）“触发”（注意这里，此时功能模块“仍未”

按“原始”参数执行）时，把原功能函数的“原始”参数“转寄”到AMXX插件中你指定的

函数中（pass），此时你可以直接获取、更改（替换）某些参数，以达到你需要的结果，

当然也可利用来做你自己函数的触发“事件”。

其实就是weaponarena.amxx武器竞技场
运行一段时间就出这个错误，时间再长点就出个hlds.exe，什么内存不能读，挂起死在那里。

在 entity_get_string(toucher, EV_SZ_classname, g_classnames[0], 14) 这句前面加个判断试试：
if(!is_valid_ent(toucher) || !is_valid_ent(touched) return FMRES_IGNORED

最好在 new CsTeams:team = cs_get_user_team(touched) 前面再加个判断：
if(!is_user_connected(touched)) return FMRES_IGNORED
