DEVLOG 6 - Crash, Crash, Crash and…. Crash

 
What I did
After spending several hours designing my ECS architecture, I realized I could do better, so I basically started from scratch and, as I mentioned in the previous devlog, I chose to use Archtypes so everything would be extremely efficient. Maybe I’m a bit too obsessed with performance…
 
The Problem
Anyway, after finishing the entire system, I started the app and it crashed. After several hours of debugging with simple print(); I thought the problem was in the memory, but I couldn’t figure out where… I finally decided to use Address Sanitizer, a tool that alerts you to out-of-bounds writes or reads, which allowed me to pinpoint the problem. I had performed a nonsensical multiplication, so the memory pointer was pointing to the wrong place, specifically to the end of the allocated memory portion, causing the metadata to be overwritten. (Apparently, when allocating memory, the program itself allocates additional memory slices that store information about the allocated memory portion.) The problem was that the app didn’t always crash, only sometimes, and I didn’t understand why. But I finally managed to get it working…
 
The Result
At the moment, this is a single entity, and since I haven’t tested the rest of the code, such as the destruction logic and entity transitions from one archtype to another, there are likely other bugs waiting for me.
