Creating a Rogue-like (like Vampire Survivors) in Unity — Part 22: Curse Boosts and All Enemy Stats

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

This article will be free until the accompanying video is released.

Now that we have the revamped enemy system that makes the enemy spawning much more exciting, let’s look at how we can improve the depth of enemy interaction in our game. In Part 4, when we first implemented stats for the enemy, we only had health, move speed and damage. In this part, we are going to add all the enemy stats you find in Vampire Survivors on our enemies, so that we are able to create enemies with more depth.

In Part 7 of our series, we created an enemy spawning system so that we had a way to generate enemies and run the core gameplay loop of our game. The enemy spawning system that we created then had a couple of limitations. For example, it was not possible to spawn the infamous Flower Wall that you saw in the Vampire Survivors game.

Flower Wall — By the end of this tutorial, you will be able to do this.

Hence, we're setting out to improve our enemy spawning system so that this sort of spawn becomes possible.

So, in Part 19, we overhauled the level-up screen so that it became modular, and made it responsive as well, so that it would display properly in different screen resolutions. In Part 20, we will do the same thing for our inventory slots.

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.
