Hello,

First thing first, thanks a lot for your amazing work, it’s really a pleasure to follow your step by step tutorial, really good explained, and easy to follow.

I’m sorry, but i can’t resolve this by myself:

Step 1 = select Garlic Character Step 2 = upgrade Knife lvl 2 and collect Spinach Step 3 = loot the treasure chest Step 4 = upgrade Garlic lvl 2 and this is what happen

(My garlic has 3 level)

Can you paste your InventoryManager code here as well?

An ArgumentOutOfRangeException happens when you try to access an array value that is larger than the size of the array itself. For e.g., if an array has 2 items, and you try to access arr[6], it will cause this error.

Hello :)

I’ve made some changes (if i chose Garlic Character, i can have the evolved knife and it is well replace) The problem come in all case if i want upgrade a weapon after knife evolution.

i’m trying to follow the Part 15 who changes everythings, and it’s 20 minuts of video for an hour of comprehension, several issues incoming and i broke my eyes comparind your code and mine, but it’s fine, i do my best :)

(i have other problems and no solution for moment health bar decrease is ok, but not increase, it’s not killing the following steps, so i don’t care about it for moment oO )

Thanks for all, really, i wish i can help you back soon (business is business and you deserve it)

I think I was on the verge of finding it when I saw the -1 in part 15, but I had no idea how to integrate it. I think it’s unnecessary to fix this bug, because from part 15, things really start to get serious. I admit the system was rather cumbersome to manage. I’m not spoiling the rest, but the wave management also seems to have a problem in my opinion, because the way the number of mobs is handled is either global or really works randomly (I think).

Thank you my friend. I’m glad I can help.

I’m not spoiling the rest, but the wave management also seems to have a problem in my opinion, because the way the number of mobs is handled is either global or really works randomly (I think).

You’re right, that’s why I redesigned the enemy spawning system in Part 21, to make it more stable: https://blog.terresquall.com/2024/07/creating-a-rogue-like-vampire-survivors-part-21/

I think I was on the verge of finding it when I saw the -1 in part 15, but I had no idea how to integrate it.

Let me know if you need more help fixing this.
