Journey's end

Hello everyone, today will be my last devlog about my game engine. I will talk about how I fixed the remaining bugs in my engine, why I think this is a good place to end it off and what my next project will be. Let's get started

Starting with the bugs, I had 2 remaining issues:

1. A rendering and physics position mismatch
2. Wrong terrain collision detection

Physics Position Mismatch

The physics position mismatch basically meant that i couldn't update the object's position manually using code and the physics engine had full control, which screwed up my debug editor.

The solution was pretty straightforward, instead of manually setting the position of my model's transform, i had to set the physics' engine transform instead using Jolt's own interface:

  bodyInterface.SetPosition(...);
  bodyInterface.SetRotation(...);

Actually pretty easy, but it took a bit to figure out.

And that was it for the first bug.

The second one with the terrain collision isn't completely fixed, but I actually do not have the energy to work on it anymore since I've been trying to fix it for more than 2 weeks.

I've gotten it in a decently good spot, the collision is almost correct, but there's a weird offset applied to the collisions' position, making it not exactly on the terrain mesh. I've honestly tried everything and I could not get it to work.

If anyone has experience with this, I'd greatly appreciate it if you would look in the code and perhaps find the issue, im very curious what's causing it!

Well, that's about it for the engine this week, and probably for a long time. This will be my last blog about the game engine, for reasons stated in my last blog.

It has been my biggest project yet and I've learnt a lot about:

• Graphics programming
• C++ (memory management, performance)
• Engine arhitecture

And this begs the question:

What will be my next project?

A compiler!

I have a few reasons for this:

• I want to learn how compilers work under the hood
• I think it's really cool to make your own custom programming language
• It'll be a good addition to my portfolio

I'll be writing it in C, one of my favourite languages and a nice breath of fresh air after all that C++.

I'll go more in-depth about the compiler next blog, when I will also start writing code for it, stay tuned!

It's a little bittersweet to move on after all this time, but I know it's the right call. And for the last time:

Goodbye everyone, see you next week.
