Er, sure, that'd be great.

I don't know if my current armor system revision is working yet, though, and haven't set up expressions (I started to, but realized that I need to learn how everything works in order to get things working properly.)

I did have a thought today, we should maybe have some way to differentiate between table-specifc values and globally available values. I was thinking maybe a "g." prefix for all global variables, but, hmm. I'm going to sleep on it.

I = input vector
N = normal of surface
R = output reflection vector

||I||=||N||=||R||=1 (there all unit length, ie normalized)
I, R, and N are coplaner

I•N = -R•N

-I+R=N

(-I)+R =  N

(-I+R)•N = N•N =

(-I•N)+(N•R) =

(-I•N)+(-I•N) =

2(-I•N) =  

-I + R = N = 2(-I•N)N



tada-> "R = 2(-I•N)N + I "

so to code that would be (remembering parameters off top of head)

void vm_vec_reflect(vector*out, vector*norm,vector*in){
float d= -2*vm_vec_dot(in,norm);
vm_vec_scale(out,norm,d); //assumeing (dest,src,float)
vm_vec_add2(out,in);
}
