GitHub Desktop for Unity - Part 2

GitHub Desktop for Unity — Part 2: How to resolve merge conflicts

This article is a part of the series:
Using GitHub Desktop for Unity collaboration

In the second part of this series, we explore a very common problem that teams usually run into when collaborating on GitHub Desktop—merge conflicts. These can cause significant delay to your work, as you are forced to handle them when they occur before progressing; and it can take a fair bit of time and skill to solve them.

Resolving them incorrectly can also cause work progress to be lost.

Hence, in this article, we’ll be covering what they are, how you can avoid them, and how you can resolve them.

Shallow vs. deep copying in Python

Shallow vs. deep copying in Python

If you’ve worked with Lists in Python before, you’ll quickly realise that they work differently from primitives like integers and strings. Consider the following:

a = "hello"
b = a
a = "world"
print(a) # Outputs world
print(b) # Outputs hello

Notice that changing the value of a does not change the value of b. This is called passing by value. In Python, Lists do not behave this way:

a = [2, 3, 4, 5]
b = a
a.append(6)
print(a) # Outputs [2, 3, 4, 5, 6]
print(b) # Outputs [2, 3, 4, 5, 6]

In the above example, notice that changing the value of List a also changes the value of List b. This is because both a and b are referring to the same List, and this is called passing by reference.

The definitive guide to installing Unity in 2024

Unity has seen growth in leaps and bounds since its humble beginnings in 2005, having IPO-ed for a whooping US$1.3 billion in September 2020. It is also looking at releasing Unity 6 — chock with a whole bunch of new features — at the end of 2024.

Since its tremendous growth over the past 3 decades, the Unity Engine has also changed significantly over the past decade, so much so that it has become difficult to set up and use, especially for new users. If you’re just getting your toes wet with the engine for the first time, here is a guide to help you figure out how to set it up — the trouble will be worth it, because it is one of the easiest game engines to use, and also one of the most robust game engines out there.
