I've setup myself in second floor of the new house, the fiber + router are too far. Solutions were:

1. ethernet cable to upstairs: intrusive
2. powerline ethernet: no hw in local shops
3. wifi booster: never worked for me, dont trust it

So ethernet cable to upstairs it is 😅

Been going through a big house move, and just now I had some time to sit for the first time, setup the workstation, and count the days that passed.. I thought I didn't commit anything for 2 days, turns out it was 4.. I'm not sure where that extra 48 hours went 😅

A few hours of face-desk + face-palm interactions in the name of Hugo and I have a full conversion that I'm happy with! https://t.co/JvsGt59EFB

<rant> Ugh I'm tired of having to fix my blog every few months because Gem/Bundler/Ruby broke things again for that specific Jekyll version I use. Honestly the dependency hell in that stack is as bad as NPM. I think I'm gonna move to Hugo, hopefully Go's stability infected Hugo.

It's time to share the github since I got something working at last: https://t.co/wH92mprWRu
#golang #goimo

[ZenithSal @zenithsal]

Ok, gonna be remaking an old Flash game of mine that was a retro FPS but because I'm working on multiple projects I'm just gonna aim to finish one milestone at a time rather than invest the rest of the year into this to completion.

I saw a video about [Kaiju engine](https://t.co/gfmtm2qokA) by @ShieldCrush , which is being written using Go as well, the developer decided to use Bullet3, I hope Goimo could become a candidate one day 😌

[ZenithSal @zenithsal]

After nearly 8 days of full time work on porting and lots of learned lessons, I finally have something working! though a little too excited mathematically I'm still elated to have a starting point to usable physics now in native Go no wrappers involved 🤩 #golang

[ZenithSal @zenithsal]

I've dived head first into porting OimoPhysics to Go. I'm about 25% into porting. Go has been a pleasure, except for one part.. generics. The limitations point to an incomplete design but it's a fairly new part of the language so there's still room to evolve. #golang

[ZenithSal @zenithsal]

Milestone wolftest is done! cut many corners and pushed many issues unto next milestone.

One issue in is a lag spike when picking up boxes, best guess is a significant GC spike somehow even though it's just 4 nodes. I'm new to Go so haven't dueled with its GC yet.

Next: Physics

[ZenithSal @zenithsal]

The first milestone is almost done, got 5 features left. Next milestone might be porting Oimo physics to Go, looking forward to that! ⚙️ 🚒 📐 #go #g3n

[ZenithSal @zenithsal]

Been a few busy ones but managed to get a bunch of infrastructure work in. Solved lots of architectural issues. I have a growing wishlist of modifications to apply to G3N, but so far got everything I needed in. I'd like to delay forking G3N as much as I can.

[ZenithSal @zenithsal]

Woho pistol socket node exported from Blender works! I just can't help but feel something is off, probably my imagination 😂

[ZenithSal @zenithsal]

Native physics simulation using Go will be hurt by Go's lack of SIMD support (I think SIMD support is planned for next year).

Regardless, a library that's good enough to run on javascript/as3 7 years ago should run great in native Go.

[ZenithSal @zenithsal]

Go's ecosystem really needs a native physics solution, I'm considering porting [OimoPhysics](https://t.co/gpawbOGjpe) to native Go at least the parts I need. It's only 15k Haxe lines.

We'll see.

[ZenithSal @zenithsal]

Got the FPS model (arm) to look and behave better: doesn't overlap world geometry, and also pitches up and down with the camera.

Looked into 3D physics solutions, Go can use C libs via cgo but suffers a context overhead. There's a bullet C API but its unmaintained and outdated.

[ZenithSal @zenithsal]

* find a solution to prevent arm from overlapping level geometry
* find or model a pistol for use as the default gun
* gun pickups in level
* animate arms for holding the gun and for firing
* attach pistol to hand bone
* fire pistol visual effect
* and adding basic sound effects

[ZenithSal @zenithsal]

Lots of progress since last build. Camera and FPS model needs better placement and I'll have to apply pitch rotation to it as well (yaw only wont work).

[ZenithSal @zenithsal]

Here's a quick video to show my progress so far

[ZenithSal @zenithsal]

Then drew an obj_map which is another png that uses a messy encoding to describe what each pixel in the level_map means.

It started simple, but digging in I found encodings for animated tiles, door events, probability spawns, etc
