Character movement with vectors- Vector scaling

Posted By Kirti P

In this tutorial we are going to learn how to scale vectors. A scalar has magnitude (size) only. A vector has both magnitude and direction.

Consider the previous example of Pacman(P). Let us assume that the Pacman is moving along the right with a velocity \vec V.

If we want to double the velocity of Pacman, we should multiply with 2 i.e 2*\vec V . In terms of x and y componets, 2 \vec V = ( 2* \vec Vx , 2*\vec Vy).

We can also half the velocity, in which case  \vec V /2 = (  \vec Vx /2 , \vec Vy /2).
