I've tried a variety of different ways, but they all seem inconsistent so I'll just show and ask. I'm trying to detect the player on an npc, which really seems easy enough but for some reason acts very strange with this code.

PHP Code:


		
			
if (player.x > this.x && player.x < this.x+2 && player.y > this.y && player.y < this.y+2)

Now I am doing this check in a timeout and clientside, and yes I did set a timer. What I see it doing is checking for the player inside these positions.
What it actually does is, sometimes it checks for the player.
My Timer is set at .1 so that's not the problem. Also i've played with the plus and minus from the this.x and this.y, but it just seems that it doesn't always catch the player on top of the npc which would be these coordinates.
Any suggestions would be awesome.

I assume there is a reason you would like to use a timeout in your code for this.
This should determine when the player is within the circle with a radius of 1 tile:

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

    onTimeout();

}



function onTimeout() {

    temp.a = {player.x, player.y, 0};

    temp.b = {thiso.x, thiso.y, 0};

    temp.distance = vectordist(temp.a, temp.b);

    if (temp.distance < 1) {

        echo("touching npc");

    } else {

        echo("not touching npc");

    }

    setTimer(0.1);

}

If you wanted to test if the player is within a 2x2 square this should work:

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

    onTimeout();

}



function onTimeout() {

    temp.a = {thiso.x, thiso.y, thiso.x+2, thiso.y+2};

    if (player.x > temp.a[0] && player.x < temp.a[2] && player.y > temp.a[1] && player.y < temp.a[3]) {

        echo("touching npc");

    } else {

        echo("not touching npc");

    }

    setTimer(0.1);

}

If you do not want to use a timeout:

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

    setshape(1,32,32);

}



function onPlayerTouchsMe() {

    echo("touching npc without a timeout");

}

I haven't tested these examples but I hope they help you.

Slight side note but you can specify ranges rather than using multiple && e.g.

PHP Code:


		
			
  if (player.x in |this.x, this.x+5| && player.y in |this.y-5, this.y|)

    this.chat = "FOUND YOU!";

I'd nest the y test but going off your example. Can still look neat(ish) without having to declare temp vars :)

Ok so this is what I'm trying to accomplish with the player coordinate checks.
Its a ladder and I'm using a custom movement system. I need to place an enable and disable custom movement but I haven't yet.
This script seems to work fine if I come top down, but if I start at the bottom it doesn't work at all.
Any help is appreciated.

PHP Code:


		
			
//#CLIENTSIDE

function onTimeout() {

  if (player.y in |y-.5,y+3|)

    Movement.ReplaceAni("climbidle","idle");

    Movement.ReplaceAni("climb","walk");

    this.ladder = false;

}



function onPlayerTouchsme() {

  if (player.y in |y-.5,y+3|) { 

    this.ladder = false;}

  else {

  player.dir = 0; 

  this.ladder = true;

  setTimer(0.1);   

  Movement.ReplaceAni("idle","climbidle");

  Movement.ReplaceAni("walk","climb");    

  }

}



function onKeyPressed(code,key) {

  if (this.ladder) {

    player.dir = 0;

      if (keydown(2)) { 

          player.y+=0.3;

          freezeplayer(.7);

      } else if (keydown(0)) { 

          player.y-=0.15;

          freezeplayer(.4);

      } else if (keydown(1)) {

          player.dir = 0;

          return;

      } else if (keydown(3)) {

          player.dir = 0;

          return;      

      }

    }

}

bump... still need help...

use disabledefmovement and attackplayertoobj. There was a ladder help script a few weeks ago, use the forum search function.

Try something like this:

- Check if the player touched the ladder
- If touched, "attach" the player to ladder
- Disable the player's normal movement
- While "attached" make sure the player is still on the ladder and check for keystrokes, move the player if necessary.

PHP Code:


		
			
//#CLIENTSIDE

function onPlayerTouchsMe() {

  if (!this.ladder) {

    this.ladder = true;

    player.x = this.x;

    setTimer(0.05);   

  } 

}



function onTimeout() {

  if (player.y in |y-1.5, y+3|) {

    if (keydown(0)) player.y -= 0.15;

    if (keydown(2)) player.y += 0.3;

  } else {

    this.ladder = false;

    Movement.ReplaceAni("idle","climbidle"); 

    Movement.ReplaceAni("walk","climb");      

  }

  if (this.ladder) setTimer(0.05);

}

Custom movement system..... disabledefmovement won't work and I don't believe attackplayertoobj is a real command. I've tried attachplayertoobj from that script, but I'm not use to using it.
Thanks MrOmega

Just seems when I use the player coordinates it doesn't function correctly. I tried this, and it's the same thing I was trying to accomplish just better, but it still doesn't seem to work. I guess I need to attachplayertoobj after all?
Thanks anyway fp4!
