This section delves into character movement through vectors, highlighting the significance of geometry and trigonometry in this context. For shooter games, leveraging vectors and measurement is essential for precise enemy targeting and elimination.

When moving a character across the screen, determining their direction of movement is paramount. This is where vectors, denoted as V→, come into play.

If you have a character and you want to move him or her across your screen. You can draw the direction of movement of your character. Vectors serve as fundamental elements in video game development, encompassing both orientation (represented by angle θ) and magnitude (known as the range or L). Understanding these components allows developers to precisely control the character’s movement.

• In the video below, it is clear that, by changing the angle and V0 other parameters are changed and all of these and other points are common and practical in the mobile game industry, especially hypercasual games.

Vectors have two main parts: direction (which includes angle, orientation, or rotation) and magnitude (how far the vector goes, also known as range). You can think of the path a vector follows as a function with different domains. More details on this topic will be explained in a future article.

A long vector drawn as X is moving very fast; a very short vector means X is moving slowly; if it is zero, it means X is not moving at all. This is that thing that is used in mathematics and physics, although as a development we need to do something different because we use a computer and it can be difficult to use this formula in the computer.

On top of this, we can show (overrightarrow{V}=(x,y))  and this is for games. With the x portion and y portion and by this way you can devide your vector into its portions. Some useful things are that we know the position of X. And every position is shown with P= (x,y) and the new position of

• Another use of vectors is in geometric transformations, which are especially practical, in puzzle games, that are shown in the below.
