Creating a Rogue-like (like Vampire Survivors) in Unity — Part 19: Upgrading the Level-up UI

This article is a part of the series:
Creating a Rogue-like Shoot 'Em Up (like Vampire Survivors) in Unity

12 May 2024: The article has been updated with some new content. The updated sections are labelled in boxes like these below.

While working on the next part of the Vampire Survivors series, one of our Patrons reported a bug with our weapon upgrade UI system in this forum topic. Basically, if you already have the maximum number of weapons / passives in your inventory, the level-up UI will still continue to give you new weapons / passives as upgrade options. These upgrade options, however, are unselectable, because the function that is fired when they are clicked on will fail, as the PlayerInventory will fail to add the item.

What began as (what I thought was) an easy bug fix became an entire part in the series, because the bug fix turned out to require a bigger overhaul on our scripts than I expected.

Hence, we have this part of the tutorial series.

Creating a Rogue-like (like Vampire Survivors) in Unity — Part 18: Implementing a Dynamic Stats System and UI

This article is a part of the series:
Creating a Rogue-like Shoot 'Em Up (like Vampire Survivors) in Unity

In earlier parts of our series, we only implemented 6 different stats on our player. Vampire Survivors, however, has many more stats than that, so in Part 15, we created a newer way to manage stats that made it easier for us to add more stats in the future.

In this part, we are going to add these stats, and create a new, dynamic, and extremely easy-to-use UI element that will automatically update itself whenever we add new stats, so we don't have to create a new UI setup whenever a new stat is added.

Creating a Rogue-like (like Vampire Survivors) in Unity — Part 17: Fixing Pickup Collection

This article is a part of the series:
Creating a Rogue-like Shoot 'Em Up (like Vampire Survivors) in Unity

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).
