| 2 | #include <sys/driver_hooks.h> |
| 3 | |
| 4 | set_driver_hook(H_COMMAND, value) |
| 5 | |
| 6 | <value> being: |
| 7 | |
| 8 | int <closure>(string command, object command_giver) |
| 9 | int <name>(string command, object command_giver) |
| 10 | |
| 11 | DESCRIPTION |
| 12 | Optional hook to parse and execute commands. If this hook is |
| 13 | used, it bypasses the normal command parsing done by the |
| 14 | driver (including the MODIFY_COMMAND and NOTIFY_FAIL hooks). |
| 15 | |
| 16 | The hook is called with two parameters: the command received |
| 17 | from the living (interactive user or NPC), and the living |
| 18 | object (the 'command giver') itself. The hook has to return |
| 19 | non-0 if the command was found and executed, and 0 otherwise. |
| 20 | |
| 21 | At the time the hook is called, query_command() returns the |
| 22 | command string and this_player() returns the living object. |
| 23 | query_verb() and query_notify_fail() return 0. |
| 24 | |
| 25 | If the hook is a string, it is the name of an lfun in the |
| 26 | command giver; if the hook is a lambda closure, it is bound to |
| 27 | the command giver before the call. |
