Making Objects Move

Unity is a great taster for the types of game development tools that are used by professionals but it isn’t a substitute for being a great digital artist or knowing maths and physics well so that you can write computer code – that’s why we’ve tried to add some notes about maths and physics concepts. 

"You may be able to drive a car without knowing how the engine works but if you want to build a car you need to be a great engineer. So it is with computer games."

Using Linear Paths to Control the Motion
of Objects

The ability to evaluate a game object’s position along a linear straight path is a very basic requirement of most game engines. For 2D and 3D games, this is usually a case of simply translating the game objects position vector by a fixed direction vector every update. The following examples explain how to find the equation of a line using two points, first in 2D space, then in 3D space.
