Now if we need to determine the direction of a vector within two given positions then the resultant vector is the answer. As we have seen above, geometrically it is represented as a line segment with the arrow showing us the direction. Vector helps us in getting the direction from one point to other. The answer is quite simple again, Vector. You must have seen many games having automatic follow mechanics, and you might have once thought about how it is being crafted and done so seamlessly. Mathematically this same thing can be expressed in terms of expression which is shown below. So, the position of the Object “A” in vector form would be Vector2(3,4), where Vector2 represents the 2D vector and (3,4) tells us the coordinates of the position. Now, this can be stored as a 2D vector as we are dealing with 2 quantities and in 2D Space. This means the position of the Object A is at (3,4), i.e., Object A is 3 Units Right from Origin and 4 Units Up from the Horizontal Line or the Origin. This notation can be written as A(x,y) which can also be written in terms of value as A(3,4). Let say, the Object “A” is 3 units right to the origin and 4 units up from the origin, where the position of the Origin is universally considered as O (0,0). As the Object “A” is in a 2d space the location or the position of the Object would be denoted by the help of x and y coordinates. The 2D space has 2 coordinates, x going horizontally and Y going Vertically perpendicular to X. Let’s understand how it is done, for example, let’s consider an object naming “A” in 2D space. As we just discussed above, the Vectors can be helpful to store data in various forms from 1D Vector to 4D Vector depending upon requirement in the Game Development phase. Here in this section, we will see the role of Vectors for Position in Games. So here we will be discussing the Fundamentals of Vector Math and its application in Game Development. The First and Foremost essential thing in the field of Math and Game Development is Vectors, not just in Games but Vectors have many real-world applications and are considered to be one of the base pillars in the field of Math. The basics of Math would initially help all the beginners to kickstart their journey in the field of Game Development. But now a major question from most of the beginners to answer here is, do we really require Math in Game Development? You might have guessed the answer from the above details but to clear again the answer is quite simple, Yes, we do require but initially, the level would be much lower. The mechanics of the game completely depends on the game type and vary accordingly, for example, for some games Physics plays a heavy role in the entire game, and for others, it’s just Transform, the logic, and Animation that does the job. A well-balanced game with good visuals, music, game design, and good mechanics would make up to the top charts with good retention over the period. Game Mechanics primarily decides how interactable and impactful your game feels and this depends on programmers how to join all the pieces together. But have you ever wondered even after Good Graphics, Game Design, and Sound Design, why a game still lacks the proper game feel? Well, that goes straight to the Mechanics of the game. This journey of Game Development includes various aspects of making a game like for example Graphics Designers making awful visuals, Sound Designers creating some breathtaking music, Programmers giving life to the game, and many more things. It’s quite an interesting journey how we develop a game from scratch and craft some beautiful experiences throughout.
