I have the code here and it should work. so the only reason why it isn't working is that I'm give the wrong position fore the player.

Just in case I also tryed the code in c++ in a test envirment that I made since I can't debug in lite-c becouse I have no debug window...

so if anyone can point me in the right way I thank you, and to further clarify I am using the plBiped01 that came along with lite-c.

function checkInTalkRange()
{
...var talkEvents = 2;
...var radius2 = 100*100;
...var x0 = 0;
...var y0 = 0;
...x0 = my.x;
...y0 = my.y;
...var i = 0;
...while(i < talkEvents)
...{
......var x1 = 0;
......var y1 = 0;
......x1 = npcX;
......y1 = npcY;
......var dx = 0;
......dx = x1 - x0;
......var dy = 0;
......dx = y1 - y0;
......var distance = 0;
......distance = (dx*dx) + (dy*dy);
......if(distance < radius2)
......{
.........talk();
......}
...i += 1;
...}
}

the problem is that the distance seams to get the wrong numbers and the my.x my.y should be from the plBiped01 altough they are called forth in a difrent file named talk so maybe thats the problem.

I used the ... to show the height in the code since it seams to delete my spaces when I past.

I can offer you to look at the function c_scan
Also, it had very goor description(how c_scan cone works) somewhere in the Aums, but i dont remember, where exactly it was

I have looked at c scan but I have to admit I have no idea what it does. by the looks of it it just makes 4 difrent scan object and I really have no idea how to work with it.

It is the Aum54.
But vec_dist is a good choice too.

I agree with Ralph, your code looks very complicated, I must admit that I dont really understand it, all of your code can be consolidated into just the one line which Ralph wrote

Anyway, vec_dist isnt equal to c_scan :)))
on the other hand, Raven, you can combine vec_dist with pan of the eitity ^^

thank you fore all the help so far but I still have a question.

what is the true x,y,z value's from the player biped

becouse it has

multiple x declerations and I am not sure wich one gives it's true position

Take this.. Its about c_scan cone

thx
