Math little problem
Author
Hello,
I'm reviewing my math for the moment, but I'm stuck on this simple problem.
The data at my disposal :
My location inside a vector called Location.
My direction inside a vector called Direction.
The distance of the move called Distance
How can I compute my new location based on those data :
NewLocation = Location where I apply a move of Distance unit in the direction Direction.
I know it's quite easy, but I really don't know how to do it :(
Tx you for your help !
Is distance a scalar?
If so, the equation is exactly as you described:
NewLocation = location + distance * direction.
If so, the equation is exactly as you described:
NewLocation = location + distance * direction.
If you don't want to overload the + and * operators, it would be
for(int i=0;i<2;i++) NewLocation = Location + Distance * Direction;

I suppose that my Direction vector must by normalized for working ?
I suppose that my Direction vector must by normalized for working ?
Yes... assuming your vectors use floats. If they are ints, a normalized direction vector won't work too good.
If you're going to just multiply the distance by the Direction vector, yes, it must be normalized.
