Variables problem

I got a particle script from a friend to learn but I coudnt put it in the level right. I got it actualy to appear in the level (the script is a class) but I cant get the x to appear at this.smokex and this.smokey even though in the script I have it set to be there.

NPC Code:

// NPC made by Irata

if (created){

this.smokex=x;

this.smokey=y;

}

join smoketest;

and in the particle script I use

NPC Code:

if (created||timeout){

with (findimg(200)){

x=this.smokex;

y=this.smokey;

}

timeout=0.05;
}

PHP Code:


		
			
with (findimg(200)){

x=this.smokex;

y=this.smokey;

}

You need to use thiso. if you're in a with() block.

I just put that but it didnt work.

PHP Code:


		
			
if (created||timeout){

  with (findimg(200)) {

  x=thiso.smokex;

  y=thiso.smokey;

    }

    timeout=0.05;

}

Im guessing its reading the var wrong from the basic script with join in it.

PHP Code:


		
			
if (created){

this.smokex=x;

this.smokey=y;

}

join smoketest;

This is the basic object (in the level)

do you have attachtoowner set in the particle? and what layer are you using for the particles? If you're using 4+ (I believe) they are screen coordinates and not level coordinates.

this is all I used in the object in the level:

PHP Code:


		
			
if (created){

this.smokex=x;

this.smokey=y;

}

join smoketest;

i used attachtoowner just now. Didnt work.
And the layer is 2

PHP Code:


		
			
if (created){ 

thiso.smokex=x; 

thiso.smokey=y; 

}

You have to set thiso.smokex and thiso.smokey which is compeletely different from this.smokex and this.smokey.

Could I see some of the particle modifyer code? Perhaps you are using some kind of static x and y modification in the code, and are not relying on the position of the NPC.

.. thiso. is used to access this. variables in the parent.

PHP Code:


		
			
function onCreated() {

  this.test = "Weee";



  with(findNPC("SomeDB-NPC")) {

    this.blah = thiso.test;

  }

}

this.blah in SomeDB-NPC will now contain "Weee"
