Recently, I gave an inteview to a Paraguayan YouTuber lucasmelor who made a great video about my PS1 game development work. The video is in Spanish, but the English version is coming soon. You can find the original inteview (originally done in English) below. P.S. I wish I had more time to do writeups about my PS1 work. For now, I mostly post about it on Twitter! lucasmelor (LM): What was the…
I gave an interview to Lee Cisco for GCORES (a Chinese website about videogames). You can find the article in Chinese here. The inteview was performed in English, so I’m publishing the original here. (LC - Lee Cisco. ED - Elias Daler) LC: Your current project runs on actual PS1 hardware, which is incredibly impressive. What motivated you to develop a brand-new game for actual PS1 hardware?…

Related: How to implement action sequences and cutscenes in Lua Making and storing references to game objects (entities) in C++ and Lua LuaVela - the LuaJIT fork I’ve worked on I’ve written many articles about using Lua with C++ on my old blog many years ago. I also worked on a fork of LuaJIT professionally and described my experiences here - this experience made me learn a lot about…
Building C++ projects and managing dependencies is hard. However, CMake makes it a lot more easier. We’ll go step by step and create a simple project which will have SFML, Dear ImGui and ImGui-SFML as its dependencies. The project will clone these dependencies’ source code from Github and build them. You won’t need to use prebuilt libraries ever again. I’ll try to explain…
Recently I’ve ported my game/engine from SFML to SDL. This was not an easy task and took me two weeks of hard work (3-4 hours on weekdays, 6-8 hours on weekends). This article will explain why I did it and which challenges I’ve faced in the process. Table Of Contents Intro Why port my game to SDL? Porting to SDL - the process Results Intro My first SFML project SFML has played a huge…
Recently, IPONWEB open sourced its fork of LuaJIT called LuaVela. The original announcement post can be found here where a lot of details about it can be found. I’ve worked on LuaVela for the last 7 months and now I want to tell about my experience. Table Of Contents Intro LuaJIT’s 2GB problem Forking LuaJIT What I’ve found interesting about LuaJIT LuaVela’s new features My…
Introduction This post will show ways of implementing actions sequences and cutscenes in video games. The code is written in Lua, but the patterns can be implemented with other languages (except the coroutine approach, because not all languages have coroutines). Action sequences frequently appear in games. In cutscenes, for example: a character approaches an enemy, says something, the enemy…
Introduction A year ago I wrote a small library called MetaStuff. It is used to register meta info about classes, which can be later used for serialization, deserialization, making GUI and so on. The cool thing about it is that you can write a serializer for your own data format, be it JSON, Lua or anything else. The library is very small, it uses C++14, requires no pre-build process, RTTI,…
Table Of Contents Introduction shared_ptr and weak_ptr Using unique ids Storing references to entities in Lua Introduction The problem of handling references to game objects (I’ll call them entities) comes up very often. Sometimes it’s child-parent relationship between the entities, sometimes it’s useful to store a reference to an object in event data, some task scheduling class…
