Hi Hive, I want to introduce a work-in-progress project I have been building: SharpForge, a C# scripting toolchain for Warcraft III: Reforged map development. The goal is not to replace the World Editor, JASS/Lua knowledge, or the existing Warcraft III scripting ecosystem. SharpForge is...

sorry for the rough English. Desync occur when area-of-effect skills attack multiple NPCs (typically 30 or more zombies) simultaneously. Also, even when using single-target skills or buff skills, desync occurs a considerable time later. This is consistently reproducible within approximately 5...

I've found plenty of talk about converting Jass to Lua, but what about the other way around? I guess I'm specifically looking for something that spits out Jass I can paste into the World Editor. I want to use YDWE PK, but it seems like it doesn't really support Lua. On the other hand, I'm...

The bottom can be changed in the options, but the top must be changed via Lua or Interference. So how do I do that? What is the path? I want it to be invisible or not to exist.

Hello, im struggling with this problem right now. Scoured the internet and didnt find any proper guide for this case, and dont know where to go with this question, and i remembered that usually on this site i can find help. In my case i try to create function which give me a length of segment...

Hello, if someone used my Lua version of the Codeless Save and Load (Multiplayer) - v3.0.1, that I shared in thread like this: [Script] - A Lua save/load system similar to TriggerHappy's GUI-friendly system, I have to say that I never made a prevention about the "%" character that had issues...

Recently getting into lua (after just getting into JASS...) and while the use of local variables makes a lot of MUI easier, I'm not certain how to deal with delayed/repeating actions for multiple instances. The spell I'm making is fairly straight forward. Mark a target area and continually deal...

I created a VSCode extension that allows you to navigate to the jassdoc definition of a function from lua code. jassdoc - GitHub - lep/jassdoc: Document the WarCraft 3 API is a project that adds documentation for the wc3 natives. To install just go to the Extension tab in VSCode, and search for...

Local Variables in GUI Since the dawn of Warcraft 3, one of GUI's biggest drawbacks was its lack of local variable support. Variables defined in GUI are always considered global—which means they are defined once and can be accessed anywhere in your map's code. This is convenient, but once you...

Do the impossible, see the invisible xxx, xxx, xxxxx xxx xxxxx! To whom it may concern: I dumped the transpiled Lua files from memory. In hindsight I wonder, why nobody has thought of this before? v2.0.2.22796 This could be useful for the rare stacktrace leading through...

Hello, friends! Recently tried to switch to lua, to use its tables, but got some issue with "debugging" as when i make a mistake in the custom code, using lua jass helper return empty window without error description and line reference as he does with jass. How to handle this problem for...

When I try to place a custom worker unit in a custom entangled gold mine (right-click on the custom entangled gold mine after selecting a custom worker), an error message and sound are output. Is there a way to fix this? Of course, there is no problem with the placement itself or operation...

Basically the title. I've been helping the CoE map by modernizing its implementation and translating it to LUA, and this gnarly desync started happening after 30min or more of game time. It turns out that, after a lot of bug hunting, the # operator in LUA does not behave consistently across...

Add a line with a meaningless comment in the code, and the program crashes after running the check. --length % scale Does anyone know why?

I wanted to dynamically modify spell list of spellbook with BlzSetAbilityStringLevelField, but it just do nothing with ABILITY_SLF_SPELL_LIST field. code is like this, A003 is spellbook. local a = BlzGetUnitAbility(u, FourCC('A003')) print(BlzGetAbilityStringLevelField(a, ABILITY_SLF_SPELL_LIST...

So... i get many search hits on the net for "convert jass to lua", but i need the opposite thing! Which i cant figure out. I am super low level in jass. Use it only when need things outside gui possibilities (local variable, damage detection system, etc.). All my jass triggers in my maps are...

I haven't seen Warcraft 3's concepts explained anywhere in a condensed manner, let me try it here. Who is this tutorial for? The beggin beginners in War3 modding, though the explanation will probably require some prior programming knowledge or a little experience with World Editor. Lockstep...

Hi there, I'm trying to implement my UI while also fiddling with GetLocalPlayer(), I wonder if this method of doing it causes any desync. Is it unnecessary to do it like that, can I just use "BlzFrameSetTexture(backdrop, s, 0, true)" in the GetLocalPlayer() block? How do I test if any...

Hi there, I created my UI in the Reforged UI Designer and exported the UI to Lua. Then I pasted it in the Map Custom Script Code only to find out it doesn't show up, the JASS version of that UI doesnt have that Problem at all, do I need to call the UI somehow? Here is the snippet: The JASS...

Inspired by Chopinski's Relativistic Missile System way of processing missiles, I've come up with an idea of mimicking OS's process scheduling inside Lua's runtime for the purpose of eliminating "processing" lag by sacrificing the fact that the code will always execute immediately upon call. At...

1. What are the constraints and best practice for FourCC allocation? (except for H*** for heroes) 2. Is it possible to place same ability on different UI button positions depending on unit type? (non-hero) 3. Does Leak matters in Reforged, given sufficient memory? (In other words, will incur...

Hello! I'm writing out some scripts but it seems like when I try to run a modulo I get some weird behavior, for example: a % b - Causes a syntax error a % n - Crashes the world editor a % 1 - Saves fine Are we not able to use variables with the mod functionality? Full Example that gives a...

Hello, I'm again trying to translate the Codeless Save Load System to Lua, but for some reason I'm not receiving the method of the metatable when I'm calling it, this is weird because I though if a table doesn't have a field, it will check to its metatable, basically I did this: ---@return...

Hello, I made a creep spawn system, it worked fine, but for some reason from a certain point when creates the first creep, eventually the game lags a lot, and I don't know why, I can't just erase things until I don't get the problem, because almost everything is important to the system works, I...

Hello, I create this thread to discuss a thing that bothers me a lot, you know that all the custom scripts are placed in a unique file war3map.lua, the problem is, we can't control the order in where they will be placed, and this matters since we have libraries that requires other libraries are...

I don't know if this was actually found, but there is a way to get the stack trace in W3 Lua, just using the error function, because is the unique function that can tell us what function called it and the function that called this and so on, so I did something like this: function GetStackTrace()...

Short question: the first code snippet (in JASS) works, but the second one (Lua) does not. function selectPriest takes nothing returns nothing call SelectUnitSingle( gg_unit_hmpr_0000 ) endfunction function selectPriest() SelectUnitSingle( gg_unit_hmpr_0000 ) end Why?

Disclaimer: This is not something you would ever encounter under normal circumstances. TLDR: At very high GC pressure processes' memory will grow. If the GC catches up, the memory will not be released to OS. I'm currently attempting to debug a memory leak in a big trigger-heavy map I'm porting...

Common knowledge has it Jass strings leak!!!1 and are bad!!!1 Let's benchmark by generating A TON of strings. Test code & setup The code below takes your chat message, like "-10" and generates ONE 10-char long string (1=10/10). That's equivalent to generating 10 distinct unique strings in Jass...

A few threads here have made me curious: "...then I found the automatic JASS to LUA converter." - Macadamia found by mistake that WorldEdit can transpile all Jass code to Lua. Nobody knows how exactly "Lua, embedded jass" - Tasyen found out, that Lua maps can have Jass code, automatically...

I searched if there is a way to do this but I didn't find anything, so I'm here to ask you.

This is just a heads up for whoever uses Lua / TypescriptToLua or similar frameworks for their warcraft 3 maps. The Lua GC is seemingly disabled. Over in the hiveworkshop discord we did quite a bit of experimentation on this issue after i realised my map was leaking 0.6MB/s, but the leaks made...
