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.
Get stuck into this physics tutorial if you really want to get your head around games design!
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.
