World Coordinates to Screen Coordinates Transformation

This script is an example of how to display on-screen objects (sprite textures, text, rectangles, etc.) linked to 3D coordinates in the game world.

Its purpose is to explain to those interested the principles of transforming world 3D coordinates into on-screen 2D coordinates,

as well as the principle of obtaining the size of the on-screen object, which depends on the distance between the player and the coordinates to which the object rendering is linked.

In this example, the coordinates are taken just above the '$' pickup on Grove Street.

The script does not carry any gameplay significance; it is needed for developing new scripts using the transformation of world 3D coordinates into on-screen 2D coordinates.

Example of possible use:

- when writing a script for store purchases to display the quantity/price of goods right above the item

- displaying the name of the interior above the marker

- creating a unique pointer to something.
