I also implemented the collision system in ECS following https://www.fatoldyeti.com/posts/roguelike4/

But some places I could go through walls, and sometimes I was blocked by some invisible blocks.
I couldn't see the pattern and the tiles seemed to be at the right places. So I decided to debug it the classical way: `printf` to the rescue!

`.` are the floor and `#` are the walls. They should be all around, but clearly, they aren't. There is a pattern to figure out, but it eluded me until I counted it.

For performance reason, all the tiles were added in a slice, instead of slices of slices.
I added them one after another in a double loop.

Basically, I inverted x and y, and so it was creating a slice of column first then rows. But I was displaying them and computing them by rows first and column next.

Pretty basic error, but the debug print made it all clear very fast.

I hacked on roublard since, I added some kind of "torch" light to the character, and made the whole environment dark with no ambient light.
It changes the mood!

#golang #g3n #roublard

IT'S ALIVE!

Now I can move the character.

It was way more adaptation as ebiten is more immediate mode and g3n is more retained, but I kind of like it as it is. I don't have a render loop, it is handled by the 3D engine.
I just use the update loop to update the position based on KeyPress events.

Problem is, now it interacts with the camera control as well, so I get to move my character and change the camera settings as well.

Finally I'm finished with gosnake, release time! 🕺

GoSnake v1.0 🐍

* Windows: https://zenithsal.cloudmillgames.com/assets/releases/gosnake/gosnake-v1.0-win64.zip
* Linux: https://zenithsal.cloudmillgames.com/assets/releases/gosnake/gosnake-v1.0-linux.zip

Learned a lot about Go from this. The code is horrendous due to my experimentation and I should really have followed a style guide, but hey .. it-works-on-my-PC (™️) 🎆
