1 | /* | |
2 | * roleplay commands for charybdis. | |
3 | * | |
4 | * adds NPC, NPCA, and SCENE which allow users to send messages from 'fake' | |
5 | * nicknames. in the case of NPC and NPCA, the nickname will be underlined | |
6 | * to clearly show that it is fake. SCENE is a special case and not underlined. | |
7 | * these commands only work on channels set +N | |
8 | * | |
9 | * also adds oper commands FSAY and FACTION, which are like NPC and NPCA | |
10 | * except without the underline. | |
11 | * | |
12 | * all of these messages have the hostmask npc.fakeuser.invalid, and their ident | |
13 | * is the nickname of the user running the commands. | |
