PDFs (Portable Document Format) is a widely used file format for documents, eBooks, and other files. However, extracting text and images from a PDF can be challenging, especially when dealing with large PDF files or… Read More »How to Extract Text and Images from a PDF File
In this tutorial, you will learn the factory design pattern and implement a factory design pattern using C# to create objects of similar types dynamically. Contact me Find the GitHub repository of this tutorial at… Read More »Implement a Factory Design Pattern using C#
This tutorial will show how to implement A* pathfinding in mazes in Unity2D by applying a generic pathfinder. We are not limited to using A* alone. We can use any pathfinders (A*, Djikstra or Greedy-best… Read More »Implement A* Pathfinding in Mazes in Unity2D
This tutorial will show how to implement mazes in Unity2D by applying the backtracking algorithm with an explicit stack. Contact me Find the GitHub repository of this tutorial at https://github.com/shamim-akhtar/tutorial-maze. Introduction to Mazes Not too… Read More »Implement Mazes in Unity2D
This tutorial will implement a reusable Finite State Machine using C++. We will then illustrate the concept by applying the implemented Finite State Machine in a few example use cases. Refactored the code and Updated… Read More »Reusable Finite State Machine using C++
Flocking and Boids Simulation The video shows my experimentation with Flocking and Boids Simulation in Unity2D using Coroutines. The rules include Cohesion, Alignment, Separation, Obstacle Avoidance and Flee from Predator. The below video shows the… Read More »Flocking and Boids Simulation in Unity2D
In this tutorial, we will learn to implement runtime depth sorting of sprites in a layer. Typically, you can associate a RenderOrder to a sprite in Unity editor. However, there may be situations where you… Read More »Runtime Depth Sorting of Sprites in a Layer
In this tutorial, we will learn to implement a constant size sprite in Unity2D so that zooming in or zooming out won’t change the sprite’s size. Contact me Find the GitHub repository of this tutorial… Read More »Implement Constant Size Sprite in Unity2D
In this tutorial, we will learn to implement camera pan and zoom controls in Unity2D. We sometimes require independent camera controls in many 2D applications, where the camera is not attached to the main character.… Read More »Implement Camera Pan and Zoom Controls in Unity2D
In this tutorial, we will implement a drag and drop item functionality in Unity. We will drag a UI item and drop it to instantiate a prefab on a 3D scene. Contact me Find the… Read More »Implement Drag and Drop Item in Unity
