Summary
Function: vector vLin( list v, float t, integer Loop );
Linearly interpolates between two vector points in a list of vectors that define a path.
Returns a vector
| • list | v | |||
| • float | t | |||
| • integer | Loop |
Specification
<lsl>vector pLin(list v, float t, integer Loop){
float l = llGetListLength(v); t *= l-1;
float f = (float)llFloor(t);
integer i1 = 0; integer i2 = 0;
if(Loop){ i1 = (integer)(f-llFloor(f/l)*l);
++f;i2 = (integer)(f-llFloor(f/l)*l);
} else {
if( f > l-1 ) i1 = (integer)l-1;
else if( f >= 0 ) i1 = (integer)f;
if(f+1 > l-1 ) i2 = (integer)l-1;
else if(f+1 >= 0 ) i2 = (integer)f+1;
}
vector v1 = llList2Vector(v, i1);
vector v2 = llList2Vector(v, i2);
t-=f;
return v1*(1-t) + v2*t;
