Won't detect players touching NPC

I'm trying to script some sort of an event, and I'm having a little trouble. Basically, the point is not to get hit by the blocks randomly warping around the room. I've got that sorted. Now, I can't seem to get the NPC to detect if it's hit a player! Can somebody tell me what I'm doing wrong?

PHP Code:


		
			
function onCreated() {
  setTimer(0.05);
  setshape(1,32,32);
}

function onTimeout() {
  
  if (this.on == 1) {
    this.timer -= 1; // Start the count down
    this.x = random(3.5,57.5);
    this.y = random(18,46);
   
    if (player.x in | this.x, this.x + this.width | && player.y in | this.y, this.y + this.height|) {
      player.chat = "I've been hit!";
    }
  }
  
  if (this.timer == 0) {
    this.on = 0; // Stop warping
  }
  setTimer(0.05);
}

Edit
I think I've found my issue. It can't detect the players x and y co-ords server side? It worked when I created a new NPC and made it clientside. If I do this to my NPC, players won't be able to see the same X and Y of the block that other players see, and that's what I'm trying to do. Anybody got any ideas?

Just wondering if I could use a triggeraction to get around this. Would it be possible to send a triggeraction from the serverside to the clientside?

Edit
I've managed to put the movement and whatever clientside, and trigger the movement via the serverside using triggeraction. Now, I need help again trying to make the NPC detect if a player is in it's x and y.

PHP Code:


		
			
/*
Timer is the amount of time it takes
to warp around the room. The higher the
timer, the longer the warp session is.
*/
function onPlayerChats() {
  if (player.guild != "Events Team") {
    return;
  }
  if (player.chat == ":warp") {
    triggeraction(31,33,"start",NULL);
  }
}

function onActionhit() {
  player.chat = "HAS BEEN HIT!";
}

//#CLIENTSIDE

const TIMER = 25;

function onCreated() {
  setTimer(0.05);
  setshape(1,32,32);
  this.height = this.width = 32;
}

function onTimeout() {
  this.chat = "Status:" SPC this.on;
  if (this.on == 1) {
    this.timer -= 1;
    this.x = random(3.5,57.5);
    this.y = random(18,46);
    if (player.x in | this.x, this.x + this.width | && player.y in | this.y, this.y + this.height|) {
      triggeraction(player.x, player.y, "hit", NULL);
    }
  }
  if (this.timer == 0) {
    this.on = 0;
    this.x = 31;
    this.y = 33;
  }
  setTimer(0.05);
}

function onActionstart() {
  this.on = 1;
  this.timer = TIMER;
}

First off: you don't even have a player scope in that timeout. You will have to loop through all players and check them all. Also, this.width and this.height are set by setShape() already, I believe, and even if they aren't, they're way off. You want them in tiles, not pixels.

I think I get what you mean by looping through the players, and I had a hunch that the setShape() set the width and height, but wasn't sure so I dumped the height and width check just for good measure. Also, how would I detect the tiles instead of pixels?

I was just saying that your width/height should be 2 instead of 32, since you already are checking for tile coordinates.

So, are you saying I should use setShape(1,2,2);?
Don't think that's what you're saying since I tried that and it didn't work.

No :oo: But this line:

PHP Code:


		
			
if (player.x in | this.x, this.x + this.width | && player.y in | this.y, this.y + this.height|) {

Doesn't make sense if you have width/height as 32, which you did.

Finally fixed this :P Thanks for your help crow (+rep)

PHP Code:


		
			
/*

function onPlayerChats() {

    return;
  }

  if (player.chat == ":warp") {
    triggeraction(this.x,this.y,"start",NULL);
  }
}

//#CLIENTSIDE

const TIMER = 50;

function onCreated() {
  setTimer(0.05);
  setshape(1,32,32);
  dontblock();
  this.ox = this.x;
  this.oy = this.y;
}

function onTimeout() {
  if (this.on == 1) {
    this.timer -= 1;
    this.x = random(3.5,57.5);
    this.y = random(18,46);
    if (player.x in | this.x - 1, this.x + 1 | && player.y in | this.y - 1, this.y + 1 |) {
      player.x = 30;
      player.y = 7;
    }
  }
  if (this.timer == 0) {
    this.on = 0;
    // Set back to original positions.
    this.x = this.ox;
    this.y = this.oy;
  }
  setTimer(0.05);
}

function onActionstart() {
  this.on = 1;
  this.timer = TIMER;
}

While setshape parameters are in pixels, npc.width and .height are actually in tiles. So Emera had this part right, maybe with the exception of checking player.x and player.y, those being the top left of the player rather than the center - player.x + 1.5 and player.y + 2.

I don't think having the NPC move clientside is a good solution, as everybody will see it differently on their own client, so you won't be able to see others get hit before they're eliminated. The event would probably be more fun if the NPC moved serverside via the move() function at high speeds, you could then check for an intersect in the clientside portion of the script in a timeout.

I know it usually does this, but he had set width and height to 32 manually in his first code snippet. Not even sure how the NPC reacts to that or if that's even possible though.
