triggeraction x,y,action,params;

Take this example:

NPC Code:

---

if (weaponfired) {

  triggeraction playerx+1.5+vecx(playerdir)*2,playery+2+vecy(playe  rdir)*2,myaction,#a;

}

---

That will trigger an action at the specified X and Y coordinates. The action name is myaction. There is 1 parameter, which is the account name of the player.

NPC Code:

---

if (actionmyaction) {

  message #p(0);

}

---

If this npc gets activated by the weapon triggeraction, it displays the first parameter as it's message.

#p(n) is a string value which holds the nth action. n is any number between 0 and whatever Stefan made the maximum value be, which I think is 4.

ok so if i did ....

if (weaponfred) {triggeraction 24,34,my action,#a;
}

if (my action) {
putexplosion3,x,y;
}

That would put an explosion there right ? (at 24,34)

No.

triggeraction x,y,action,param;

X and Y are the coordinates of the triggeraction event. Action is the action. Param are the parameters.

NPC Code:

---

if (weaponfired) {

  this.x=24;

  this.y=34;

  triggeraction playerx+1.5+vecx(playerdir),playery+2+vecy(playerd  ir),explosion,#v(this.x),#v(this.y);

}



if (actionexplosion) {

  this.explosionX=strtofloat(#p(0));

  this.explosionY=strtofloat(#p(1));

  putexplosion 3,this.explosionX,this.explosionY;

}

---

In this code, it sends a triggeraction with the parameters 24 and 34. 24 is saved in the string #p(0) and 34 in the string #p(1). Once the NPC which holds the action is activated, it sets the values of #p(0) and #p(1) into the variables this.explosionX and this.explosionY. It then uses those variables to create the explosion.

  this.explosionY=strtofloat(#p(1));

  putexplosion 3,this.explosionX,this.explosionY;

Please explain the 'vecx(playerdir),playery+2+vecy(playerdir)
what does the vecx and vecy stand for ? (vecinity ??)

*zips in to beat Boco*

Please explain the 'vecx(playerdir),playery+2+vecy(playerdir)

As stated in commands.doc:

vecx( dir ) vertical movement vector (0,-1,0,1)

vecy( dir ) horizontal movement vector (-1,0,1,0)

If you know arrays, you'll know that it will call one of those four numbers based on the players direction.

And that's the best I'm explaining ^_^;

i think i have a somewhat ok understanding now ...
