The big picture

For 3D games (and to some extent, 2D games as well), a fundamental class of object is the Vector3 class objects that store and manipulate (x, y, z) values representing locations in a 3D space. If we draw an imaginary arrow from the origin (0, 0, 0) to a point on the space, then the direction and length of this arrow (vector) can represent a velocity or force (that is, a certain amount of magnitude in a certain direction).

If we ignore all the character controller components, colliders, and the physics system in Unity, we can write code that teleports objects directly to a particular (x, y, z) location in our scene. Sometimes, this is just what we want to do; for example, we may wish to spawn an object at a location. However, ...
