Fine, make a level..
a NPC:

if (timeout||playerenters) {
this.msg=123456;
unset this.msg;
timeout=0.05;
message #v(this.msg);
}

Try that.

He is setting a string, not a variable.

setstring this.word,Blah;
unset this.word;

message #s(this.word);

Will still message Blah.

Not when I tried it x.x think about it, here's the logic:
if you do setstring clientr.test,hi; and you open the attributes, the string is shown in the flags section therefore it can be unset. If you still dont believe me, try this, its a weapon called Test:

NPC Code:

---

if (actionserverside) {

  putnpc2 playerx,playery,{

    if (created) message I'm here;

    if (playerchats) {

      if (strequals(#c,set)) setstring this.test,hi;

      if (strequals(#c,unset)) unset this.test;

      if (strequals(#c,say)) message #s(this.test);

    }

  }

}

//#CLIENTSIDE

if (weaponfired) {

  triggeraction 0,0,serverside,Test,;

}

---

just say "set" "say" you'll see the npc say hi
then say "unset" "say" the npc will then say nothing b/c this.test is no longer there

NPC Code:

---

if(created)

set flag name;

---

Use unset flag name in that case, not with variables or strings :P

That's what i was saying..

geez lame people.
find another thread. this one has already been answered.







and to delete a string use setring

NPC Code:

---

setstring <string>,;
