NUKI1 in Retrospective / +dev-log

See here NUKI1 - Nuki and I +explore the Galaxy - on baden.dev

Quick introduction

NUKI1 or Nuki and I explore the Galaxy is a +puzzle-platformer mix, and my first commercially released game.

I tried to create a new unique genre-mix (in the somehow worn out +platformer genre) implementing ideas that lingered in my mind for years, +a lot of those inspired by some good old DOS games I played.

Concept

At first I wanted to make a top-down puzzler game, but felt that I +needed more “action” and “physics” like advanced and precise platformer +movement and artillery-game and rocket movement.

Also, an inventory system with object interaction like in a RPG and +puzzles that you need to solve in real life (on paper/via web +lookup/etc.) were on my list.

At the end I decided to make the game in 10 unique levels and +integrate all of my crazy genre-mix-ideas.

Implementation

I started the game in Python only using tkinter as a “side-project”, +when I hit performance problems and coincidentally bought an ODROID GO +SUPER device for cheap.

I thought it would be nice to support the ODROID, and from then on I +rewrote the game in C++ with ODROID support in mind (wasn’t far +anyways).

I only wanted to use minimal dependencies, so it was SDL and +tinyxml2, the rest of the game I wanted to write completely on my own, +since that’s where the fun lies! Writing physics/vector/math/… classes +and basically the entire engine on my own!

Programming

Not so fun

Collision detection and handling +
- Wanted to have “pixel-perfect” collisions using AABB (Axis-Aligned +Bounding Box) collisions with some second check of “penetration”, which +meant looking at how deep until the first row has a pixel that overlaps +with other entity. +
  - Getting this “okay” and also fast enough on the ODROID was quite +challenging
Music: I LOVE music and someday I hope I’ll make something, for now +I didn’t want to use third party music, so…

The most fun

Physics
+
- Movement +
  - Jump/Double-jump
  - Jetpacking
- Trajectory (Bow, Projectiles) +
  - Recoil gun
- Spaceship movement
Implementing the “ProNav” algorithm (see Wikipedia: +https://en.wikipedia.org/wiki/Proportional_navigation) for homing +missiles, especially after having the math/vector/linear algebra classes +done
Item usage / inventory usage
+
- equipping items and have them change stuff in the game world

Stats

All in all, with rewriting a huge part of the game (while getting +better at C++), a lot of pixel painting and planning, I estimate around +1500 - 2500 hrs of work for everything.

A lof of time was lost in the first Py version, me getting better in +C++ and rewriting a lot of stuff.
