Original link: https://blog.codingnow.com/2022/10/telecom_ipv6.html I was tossing around BT downloads at home on weekends and found that UPnP couldn’t work, so I went to Guangmao to see what was going on. I found that the telecom broadband is already dialed by the optical modem by default, and the router at home is used as a secondary …
Original link: https://blog.codingnow.com/2022/09/cargo_matching.html We’re making an automation-themed game like Factorio. There are many algorithmic problems encountered in game development, and the solution process is very interesting. For example, I wrote a fluid system before. The biggest difference from the Factorio experience is that we don’t use conveyor belts as the primary means of logistics, but …
Original link:https://blog.codingnow.com/2022/09/multithread_lua_vm.html ltask is a library that functions like skynet. I mainly use it for client environments. Since it was designed later than skynet, I experimented with many new ideas on it. A requirement came across recently: a third-party C/C++ module embedded in our game engine provides several interfaces in the form of callbacks. When …

Original link: https://blog.codingnow.com/2022/09/routemap.html In the game we’re making, traffic and logistics are based on a road network. The road network is actually a (undirected) graph composed of intersections as vertices and roads as edges. Since we have a large number of vehicles on this network, I need a space efficient way to store the paths …
Original link: https://blog.codingnow.com/2022/08/memory_compat_protobuffer_json_unmarshaling.html Today, my colleague sent me a post , talking about the problem that when golang processes a large number of concurrent json / protobuffer unmarshaling transactions, a large amount of (10GB) temporary memory may be generated, which cannot be recovered in time. My point is: if a module of a system is …
Original link: https://blog.codingnow.com/2022/08/luaecs_eid.html There was a problem left when designing luaecs last year: how to refer to a specific entity. At the beginning, I thought that the tag system could be used flexibly to solve most of the problems; or the user could build a 64bit ID component by himself, and use the binary search …
Original link: https://blog.codingnow.com/2022/07/rmlui_style_cache.html The GameUI of our game engine uses RmlUI . My idea is to use mature CSS to describe the presentation of the UI, and use the method of web front-end development to make the UI of the game. But I don’t want to embed too complicated web rendering engine, and the needs …
Original link: https://blog.codingnow.com/2022/07/refactor_math3d.html The math library used in our engine has been tinkered with for a long time. During this period, many ideas were accumulated. Recently, I am doing performance optimization of the engine, rewriting some hotspot systems found in C/C++, and refactoring the math library by the way, so that it can better take …
Original link: https://blog.codingnow.com/2022/07/group_mount.html Some time ago we added object grouping to the engine . The motivation for this feature is to have a mechanism to quickly filter out the set of code to process when the number of objects in the entire game world far exceeds the number of objects that need to be processed …

Original link: https://blog.codingnow.com/2022/06/ecs_group.html Currently, we use ECS to manage objects in the game engine. When the game scene is large enough, there needs to be a mechanism to quickly filter out the subset of objects that need to be rendered. In other words, if you create 100K entities, but only 1K entities need to be …
Original link: https://blog.codingnow.com/2022/06/vla.html VLA (dynamic-length array) is a very convenient language feature added by the C language after C99, but MSVC has clearly not supported VLA. And Linux kernel code used to use VLA, and now VLA has been removed. It appears that VLAs pose more security concerns than convenience. However, in daily development in …
Original link: https://blog.codingnow.com/2022/05/roguelike_lua.html I love RogueLike games, I mean literally Rogue -like games. In this kind of game, the screen is the least important part, as long as it can clearly express the interactive meaning required by the game. I have a special hobby for game interfaces that are pieced together with characters. When I …
