CS怎么在加阴影（在控制台里面）？

在脚本里面加入 alias dev1 "developer 1"
alias dev0 "developer 0"
alias snp "snp1"
alias snp1 "+attack2; wait; -attack2; hud_draw 0; alias snp snp2; dev1; echo -[Zoom 1-; dev0"
alias snp2 "+attack2; wait; -attack2; alias snp snp3; dev1; echo -[Zoom 2]-; dev0"
alias snp3 "+attack2; wait; -attack2; hud_draw 1; weapon_knife; lastinv; alias snp snp1; dev1; echo -[Unzoom]-; dev0"
alias sec "sec1"
alias sec1 "bind mouse2 snp; alias sec sec2;dev1; echo Sniper Blackout LoadeD; dev0"
alias sec2 "bind mouse2 +attack2; alias sec sec1; hud_draw 1;dev1;echo Sniper Blackout UnLoaded; dev0"
bind [ sec1
bind ] sec2

好象在设置里面有个显示玩家阴影，打勾就行了

那是什么命令？？
