[SRC] Atcommand Events

Fox RM · 16 декабря, 2014

Доброго времени суток, сразу скажу по поводу исходников, нашел мод в своем старом эмуле, соответственно мод написал [ToastOfDoom], под eAthena (в rAthena ,по моему, есть по дефолту этот скрипт.)

Мод включает в себя 3 команды, а именно:

bindatcmd (<atcmd>,<event>);

Да бы каждый раз не править src , в первой строке atcmd - вводите название команды (бинд) , во втором event - название лейбла который будет использовать скрипт нпц. Чтобы все стало понятней, ниже будет рассмотрен пример работы.

unbindatcmd(<atcmd>);

Это позволит удалить все существующие привязки к определенной atcmd.</span><br />

useatcmd(<atcmd string>);

Работает по принципу atcommand() . Более подробный принцип работы увидете ниже, в примере.

Когда atcmd перенаправляется к лейблу, параметры этого atcmd передаются следующими переменными:

. @ atcmd_command $: atcmd который используется.

. @ atcmd_numparameters: количество параметров

. @ atcmd_parameters $ [-]: Параметры, указанные в массиве

Пример:


- script atcmd_sample_inject -1,{
OnInit:
bindatcmd("warp", "atcmd_sample_inject::OnAtCmd");
end;

OnAtCmd:
if(Zeny >= 1000) {
set Zeny, Zeny - 1000;
useatcmd "@warp " + .@atcmd_parameters$[0] + " " + .@atcmd_parameters$[1] + " " + .@atcmd_parameters$[2];
} else {
dispbottom "Sorry... you need at least 1000z to use this service";
}
end;
}

Соответственно вводите в игре @warp и в работу включается лейбл OnAtCmd: ,объяснять его работу не буду, т.к все итак понятно.

Непосредственно сам код:
