Tags: GameDev, 3D, cross-platform, C++, Android, Windows, OpenGL ES 3.2. This blog has evolved into a practical, step-by-step guide on writing a cross-platform 3D app (game) from scratch. Writing own game is my old dream. Now, I finally know how to do it right. Have a few ideas in mind what it could be, haven’t […]
The Architecture Logic of Biblical Creation: programmer’s POV Tags: System Design, Linguistics, Philosophy, Ancient History, C++, OOP In short: What if Biblical Creation wasn’t about “making” stuff ? Disclaimer: This is NOT a religious discussion. I’m not trying to question the Bible. I’m trying to question my personal perception of it. This is my attempt […]
An important step that is missing from all instructions: Before everything else: let’s make sure, that app is releasable. At first I didn’t do it myself, which I later regret more than once. Step 0. Release build. If you have working release build already, then just skip this step. Otherwise I assume, that everything you’ve […]
Some people ask why I choose not to use Unity or Unreal, considering them obvious, almost the only possible choice. Will try to explain in details: From the beginning I was looking for what could differ me from what is usually seen on the market (including Unity and Unreal projects). There was a list of […]
Finally, our project has reached a point where it can be shown as a standalone demo, in Microsoft Store for example. I didn’t expect it to be easy, and it sure wasn’t. I can’t say that Microsoft’s instructions I have used were “wrong” or “inaccurate”, but sometimes they were SO complicated, not sequential and confusing […]
Contrary to my expectations, these 2 topics were not that complicated. So I decided that one article on them would be enough. Here’s how it looks and sounds like: Sound Essentially, the topic came down to finding a suitable audio library/API. I’ve checked a few, including OpenSL, OpenAL, irrKlang, SFML, FMOD, PortAudio, SDL2, etc. Many […]
Now we’ll try to implement game objects’ reaction on our own manual input (mouse for instance). The main part is how to determine which game object the mouse is pointing at. We’ll use the same approach as in previous chapter. Unlike in collision detection we’ll calculate object’s sizes/position not in world X-Z plane, but in […]
Collision detection is the heartbeat of game logic. Essentially, any game is just a set of rules defining how objects behave when they interact. Think of a shell and a tank: when they meet, the shell is destroyed, the tank explodes, and the game state changes. But how do we mathematically determine if two objects […]
Wanted to call this chapter “Game Concept” or “Game Scenario”, but that would be too premature. There is no clear concept or script in my head yet. Although the visual concept and general direction are more or less settled down. When thinking about a future game, it’s important to decide not only what you WANT […]
We now have a graphics engine capable of generating and displaying 3D models. However, it uses its own model format (XML files). Of course, it would be great to use other (standard) 3D formats as well, that can be downloaded from the Internet. After some research I settled on GLTF/GLB (GL Transfer Format, GLB is […]
Cross-platform graphics engine, GameDev, 3D, C++, Android, Windows, OpenGL ES, Visual Studio, Android Studio Well, it’s a big topic. I’d even say HUGE. Here we’ll need to decide how to build and render our scene/models, where we’ll get our 3D models from, how we’ll load, unpack and control them, which and how many shaders we […]
