Amazing thriftstore haul today! Never ever in my life would I have expected to find a CIB GBA 😱

and finally, we changed the lock screens of our workstations to the following image - which was also rendered on a real PS1 (screenshot from emulator though for simplicity), with a hacked BIOS to display the Guerrilla logo in PS1 colours.

and a little hidden birthday message for those that input the correct secret code (yes, ofcourse it was the Konami code 😂).

for a bit of interaction, I had added a "firework" particle that shoots up every time you press one of the corresponding icon buttons.

We had a celebration party at the office, so obviously I took the opportunity to make something which ran on real hardware!
I made an infinite loop of logo variants Guerrilla had over the years. Cycling randomly every 20 seconds (or if you press start button), with a bit of camera animation added.

Happy 30th anniversary to my all-time favourite game console!
I have been up to some cool stuff recently, which I did for @guerrilla.bsky.social - let me show in a thread ❤️

omg, I was given a zippo display, and its absolutely perfect for gameboy games!!

Still have to fix colours (and UV’s) for this, but it does allow for less artifacts closer up to the camera this way!

Spent a pretty long time rewriting my entire renderer focussing on better maintainable code. Unfortunately performance was sacrificed in doing so, but I can do cool things now like dynamic subdivisions!

the box is a little beat, but the console is in absolute mint condition!!

Then I only have to query the ray against a few boxes (drawn in red if hit), and I only need to test like 10-15 triangles instead of 1200 at that point!
Performance has greatly increased on this (and I fixed some division by zero issues too!).
Next up; animations!

I have spent the last few days optimizing my raycast queries. I am using a ‘BVH’, which is pretty much a fancy subdivided octree holding references to subsets of triangles of a bigger mesh. Generated at loadtime:

I have once again expanded my legs with nerdy artwork 🤓😂

I have Raycasts to Triangles working finally as well! That took me an entire damn week to figure out 😖
With that though (pending some optimizing), I should have nearly programmed all components to start making games with this engine/framework!

Raycast to AABB working now as well! :D

Raycast to sphere working now too! This one took me quite a bit to figure out, mostly due to fixed point math 😂

More progress; Been slowly building my own collision system!
Have AABB and Sphere colliders all working properly now..
Next is to add Raycast to these types, and then do a polygon check for that too.
Ideally I would add cylinders, and that would cover most needs for any basic game!

Absolutely loved all of Indiana Jones and the Great Circle ❤️ Cannot wait for the DLC!

also implemented AABB intersections, which work, but need to think of a good way to actually handle the collisions (just resets to last ‘good’ position for now 😂)

Holiday also means more PS1 engine progress! I got (face) normals generated at load time, and light calculated on those to shade the faces.
Absolutely gonna need a fuck ton of optimization 😂

My Holiday started this week, so naturally I go clean around the house. Genuinely forgot I had this stored, and I am not sure how many I own anymore now 😅 I think this is the 3rd or 4th one 😱
