====== Script to prevent actor from walking thanks to 3d/2d conversion imperfection ======

Sometimes you can encounter the following problem. Your actor stands at some spot he/her walks thanks to the hotspot clicking. You click again on the hostspot and actor strangely enough turns around. This is caused thanks to 3d/2d space conversion and the problem is that the actor thinks, that he has to walk one pixel to the side.

Fix is simple: create a script which you attach to your actor. Inside put the following code:

<code script>#include "scripts/base.inc"
 
var C_DX = 2; // thresholds which define that the actor is on one place 
var C_DY = 2;
 
function abs(X)  //returns absolute value of the number
{
    if (X <0) X = X*-1;
    return(X);    
}
 
method GoTo(DestX,DestY)
{
    
    if (abs(this.X - DestX) < C_DX && abs(this.Y - DestY) < C_DY) return; // Let's not spin by approx clicks.    
        this.GoTo(DestX,DestY);
}</code>
