In the next part of our tutorial series, we will be implementing a save functionality for our coins and coin pickups. We'll be introducing a coin system that persists across play sessions, allowing players to track their progression. Alongside this, we'll add new pickups that reward players with coins during gameplay.

Currently, there are no persistent rewards tied to completing levels. By introducing collectible and usable coins, we create a more engaging experience where players feel rewarded for their efforts and have meaningful goals to work toward.

Update 18 February 2024: Added a new section to fix a bug with the health bar not updating after picking up a health potion.

If you've been following our series for some time, one thing that you will be aware of is that our pickup system is a little janky, because sometimes our items will miss the player if he is moving too fast, or moving at an odd angle (thanks to g Dni for pointing this out).

If you’ve ever used a Rigidbody component in Unity, you may have seen a couple of settings on the component which may be a little difficult to understand the meaning of. On this site, we have covered what some of these settings mean and what they do, such as:

• The Collision Detection property, which controls what kind of collision detection mode your Rigidbody is using. This is because using the wrong Collision Detection mode can cause tunnelling.
• The Interpolate property, which controls how a Rigidbody’s position updates, and prevents things like camera jitter when used properly.

When using Unity to develop games, many people may choose to use Plastic SCM to collaborate with their team. However, with multiple people working on the same project, a merge conflict may sometimes occur.

While I was doing SEO for this blog in the past few couple of days, I’ve come across a set of HTTP security headers I’ve never heard of before. These are a set of HTTP headers that you can deploy on your website(s) to tell browsers how to interact with your site in a variety of situations, and they can help to prevent things like cross-site request forgery or iFrame injection XSS attacks from happening on your site, as well as improve your website(s) SEO score (apparently).

Needless to say, I immediately sought to implement them. If you’re looking for some settings that you can copy and paste right into your own web server, read on further.

Recently, while working on one of my projects in Unity, I opened one of my C# scripts, and… my Unity Editor decided to get itself stuck on the loading screen for a really long time. This led me to search online for a fix, and it took me quite some time.

If you’re experiencing the same issue, this article is for you. Hopefully, you won’t take as much time as I did to fix this error.
