Yea, just wondering, say you had a tree and 5 apples, and you wanted to find which apple was the closest of all 5. I was thinking instance_nearest, but it returns any object.

Ideas please?

Code: [Select]
var idd;
var sqr_distance;
var xx, yy;
idd=0;
sqr_distance=-1;//default distance
xx=x;
yy=y;
with apple
{
 if (sqr_distance==-1||sqr(xx-x)+sqr(yy-y)<sqr_distance)
 {
  sqr_distance=sqr(xx-x)+sqr(yy-y);
  idd=id;
 }
}
//idd is the id of the nearest apple. If idd=0, then there are no apple instances in the room

instance_nearest(x,y,obj) Returns the id of the instance of type obj nearest to (x,y). obj can be an object or the keyword all.

Put apple for obj? Looks like it should work..
