Minecraft Modding: Laser Gun

While guns are not terribly interesting, this tutorial will cover one rather tricky thing to do in Minecraft, which is often associated with guns: raycasting. Simply put, this is the process of finding what object we are looking at. No command is sadly able to do that, so we will need to come up with an alternative solution.

Delegates, Lambda Expressions & Closures in C#

If you are familiar with programming, you might have heard of a specific paradigm called functional programming. Most modern languages, such as Java and C#, have integrated some functional elements over time. Other, like Scala and Haskell, were built around that very idea of functional programming.

This online course will look at some of the functional features available in C# 3.0, including the concept of anonymous functions, delegates and lambda expressions. But before doing that, we need to understand what functional programming actually means.

If you are interested, keep reading, and we will explore the following topics:

  • Anonymous functions
  • Delegates
  • Anonymous delegates
  • Multicast delegates
  • Lambda expressions
  • Lambda statements
  • Expression-body members
  • Expression trees
  • Local functions
  • Closures

Tentacle Suckers Shader

Following the unexpected success of the tutorial on Inverse Kinematics for Tentacles, I have decided to share the shader that I used to make them so realistic.

If you are not familiar with shaders, fear not. This tutorial will be target at beginners, and you’ll only need a basic understanding of how Unity works.

  • Introduction
  • Part 1. Creating a new Shader
