NPC spawing point????

[Saint Revla]

function onCreated() 
  setshape(1, 32, 32);

function onActionDied() 
  setlevel2("levelname", x, y);

//#CLIENTSIDE
function onPlayerDies() 
 triggeraction(x + 0.5, y + 0.5, "Died", null); 

Or

//#CLIENTSIDE 
function onPlayerDies() {  //function for when the player dies 
 setlevel2("Name.nw",X,Y);  //syntax: setlevel2(LevelNameInString,x,y); 
} 

I can't really understand what you mean by spawning?
The above is for when a player dies, spawn.

 Spoiler

If you meant the below.

If you mean regular npcs, such as objects. Then you can just place them using the NPC-Icon everywhere you want. They can spawn when player touches, set timer or if a player enters an area.
