Need Help - Detection
 

I was wondering if there was anyway to detect if a moving NPC touches a player, or is a certain distance from a player so that the NPC can carry out something.
ie.
A moving NPC touches the player and their health is reduced.

If anyone could guide me towards how you would go about doing this it would be appreciated. :)

if (playertouchsme) ?
or
loop through every player using distance formula to check if they're within a distance.
Distance formula: D=((x1-x2)^2 + (y1-y2)^2)^(1/2)
where (x1,y1),(x2,y2) are the coordinates of the two objects (this case npc and player)

if (playertouchsme) only triggers when the obvious happens: the player touches the NPC, not the other way around. To do what you're wanting, you would need to have a timeout constantly check the distance of the player from the NPC, as was already mentioned. However, use 0.5 at the end of that formula rather than (1/2). There's no need for extra calculation there.

o_O Why can't you just use testplayer to see if it is close enough to touch the npc

What does getting the index of a player...o wait you mean like
testplayer(x,y)? where x and y are the coordinates of the npc?

Serverside scripting functions:

NPC Code:

---

pindex = getnearestplayer(x,y)

with (players[pindex]) {

  distance = ((x-playerx)^2+(y-playery)^2)^0.5;

  if (distance<2)

    // do stuff

}

---

or

NPC Code:

---

pindexes = getnearestplayers(x,y,playerhearts>=3)

for (i=0; i<arraylen(pindexes); i++) {

  with (players[pindexes[i]]) {

    distance = ((x-playerx)^2+(y-playery)^2)^0.5;

    if (distance<2)

      // do stuff

  }

}

Hehe, I didn't know there was a getnearestplayers ;-)
cool

Why isnt there a ; at the end of the getnearestplayers?

a typo

OMG Stefan, a type?!? lol j/k this proves that everyone makes mistakes ;)

Same concept. It's still going to have to be used in a timeout, or in a movementfinished block.

I thought we weren't allowed to post full scripts ? Bad stefan. Bad boy.

He did it twice though... =o

Shh! he will smite thee for unmasking his fallous!!
yes I made that word up, it's a very good word if I may add

*gets back to updating commands.rtf* ... *wonders if anyone cares about the updated commands.rtf*

Oh dear god i do.

Add getnearestplayers, command wench.
