Yello!

While developing some functions to rotate entites around I encountered a Problem with the fatan function. I suspected this to be the atan2 function, which is an extended version of the tan function, however fatan does merely return values of atan(y/x) if x!= 0 and 0 otherwise.

for anyone who is interested there is a simple way to circumvnt this limitation:

Code:

---

function atan2(y, x)
{
	if(x>0) {
		return(fatan(y,x));
	} else {
	if(x<0) {
		return(fatan(y,x)+180);
	} else {
		return(sign(y)*90);
	}}}
}

---

I was just wondering if fatan´s behaviour is intended. Took me a few hours to catch that one...
