This is your 23rd thread in the NPC Scripting forums that I have counted asking for help, and still, you do not read what people say. This annoys me, and others, so please learn to read what is said when people try to help.
What ApothiX says is correct. Add your parameters to the triggeraction (#v(mousex) and #v(mousey)). For example.
PHP Code:
triggeraction 0,0,serverside,MyWeapon,place,#v(mousex),#v(mousey);
... and read them on the serverside using strtofloat(#p()). For example.
PHP Code:
if (actionserverside)
{
if (strequals(#p(0),place))
{
putnpc2 strtofloat(#p(1)),strtofloat(#p(2)),join classname;
}
}
