Mouse Screen Coordinates to Game Viewport Coordinates | Coding a 2D Game Engine in Java #30

Описание: Join the Discord:   / discord  

In this episode we fix the bug from the last episode where the mouse coordinates were being calculated incorrectly because of the new position of the game viewport. This was a simple fix by calculating the world coordinates using screen coordinates relative to the game viewport's position and size.
