This is merely a GitHub repost of zcmd by ZeeX because it does not exist on GitHub making package management with sampctl difficult.
The original topic and documentation is here.
@Zeex: If you want to host this on your own account, open an issue and I will delete this repository.
Simply install to your project:
sampctl package install Southclaws/zcmd
Include in your code and begin using the library:
#include <zcmd>
For usage documentation, please see the original post linked above.
Quick example in case that link ever breaks:
CMD:help(playerid, params[]) {
SendClientMessage(playerid, 0xFFFF00FF, "This is the help command");
return 1;
}
