Allow me to introduce you to the: Ultimate Reforged UI Designer (RUID) There is now a new thread for this tool. This thread is no longer being updated. - Designed to take Map modding to the next level, with graphical Frame creation and adjustment. - Made for everyone, from the humble GUI...

I'm getting started in Lua after 4 months of learning Jass and vJass, I know some basics things like I can't use the words "call", "set", "takes" or "returns", for code functions I can do it inside of the current function, the IDs needs FourCC and all the variables can have any type of value, I...

This is for my map: Fantasy Life. It is slightly similar LoaP in the regard that it has jobs, but mostly different. More details in the map link. So some of the things that we will be making: Tens of mini-games using Frames and UI for jobs and events. (the main point) UI for almost anything...

Hey all, I have a question. When i write this line: print("Congratulations to", GetPlayerName(Player(0)), ". You have been elected to rule the kingdom!") why is it printed ingame like this: Congratulations to_____Name of Player______. You have been elected to rule the kingdom! (_____ shows...

Hello, First off I realize that both ceres and cerrie have more-or-less been abandoned. I didn't want to let a little abandonware come between me and excellent tooling so I've given a shot at using them. Honestly all-in-all my experience has been excellent. (Regardless of current project...

Hey, So, I've been dealing with this issue of and on with my map I'm working on. (AOS) Basically almost every game, about 15 minutes in, the game freezes and then crashes. I've checking my handle count and it never goes above 9000. (lots of units on the map), and I've simulated a Memory leak...

Alright, so I'm trying to create a Unit with these properties (it's basically a Guard Tower with special behaviors): 1) It cannot move normally BUT it can be moved with triggers using SetUnitX/Y. 2) It cannot turn. 3) It cannot attack but it can acquire targets. I use a custom missile system to...

Hey all, i have a problem with my following triggers: The global variables are already created. function Trig_SetExplorationReward_Filter4() return GetOwningPlayer(GetFilterUnit()) == GetOwningPlayer(FlagUnit) and UnitAlive(GetFilterUnit()) == true and IsUnitType(GetFilterUnit()...

Hey all can someone tell me why this trigger isnt starting or repeating when the game starts? function Trig_Enemy_Spawn_Conditions() return udg_SpawnCap < 500 end function Trig_Enemy_Spawn_Func004Func002A() udg_TempLoc = GetUnitLoc (GetEnumUnit()) udg_SpawnCap = udg_SpawnCap +...

This a nasty bug happening only in the not upto date Warcraft 3 V1.31. And only for maps in Lua mode. After the game was Saved&Loaded FourCC stops working. This breaks any Unit/Ability/Item/Buff/Destruct/Terrain... Type comparer in GUI and written code. This does not happen in the upto date...

Hello! I had this idea since Blizzard implemented Lua and the custom user-interface in Warcraft III. When I was testing my other projects (Perlin Noise, File IO, Network), I'm using player chat event and Lua's load function as an input, DisplayPlayerTextMessage/print for output, to debug my...

Hey, so I'm fairly new to Lua and I created this unit spawning script for my map and it seems like my map keeps crashing around the same time every time I launch it. This is my first foray into Lua so I'm not super sure the things that I need to look out for or do to make sure that I'm not...

Hello everyone ! As most of Lua users, especially in the wc3 context, there is a big problem we often encounter. Lua is extremely permissive as its variables have no type. You all know that only values are typed in Lua. Declaring globals not being mandatory in Lua, combined with this lack of...

Introduction [Edit] Just to be perfectly clear, previously local files could only be saved using a registry flag, this has been changed in previous patches, 1.30 or similar and one can always save files now. Greetings fellow modders, Time for another write-up, and this time with actual...

Introduction This is not a finished solution that is ready for normal usage, i don't recommend using my example project in a serious project since its very rough and unpolished Proof of concept. Its somewhat of a deep dive into my findings when experimenting with with my theory of a...

Is there a way to protect maps that uses lua scripts? Up until now I have been using Map Optimizer 5.0 but that no longer works.

Hello there, just a quick code to help people trying to catch when a building with root ability is actually rooted / uprooted. To be honest, detecting an uproot is really straightforward as the effect is immediate. But catching when a building has finished re-rooting is more complex. After a...

Hello there ! I know that we can use this native from common.ai native UnitAlive takes unit id returns boolean by simply declaring it in the jass script. But now that I use Lua, how can I declare this native in order to use it in my Lua functions ?

Hello guys !! I don't know if it is because I have worked all night, but I am stuck on tracking a compile bug with my latest spell implementation. I have this really long Lua function that fires a "unknown error" when WE tries to save the map. I have narrowed the problem down to a very small...

Hello everyone. I recently had issues with portrait animations for a Flying Balls model, and the model works perfectly so far. For a custom ability called "Torrefaction" that is supposed to burn the target for a few seconds, preventing it to move (yes I know damage would be more sensible but I...

Hi. I was testing some Lua maths in Warcraft 3 involving quadratic and apparently the obtained numerical value differs depending on whether math.sqrt or "^(1/2)" is used. Mathematically, they should be equivalent, thus, the same answer should yield. However, there seem to be a large difference...

Hello! I am currently in the process of converting a map from JASS to LUA. Right now the map has no JASS script calls besides the standard manual garbage collection in GUI triggers. The gist is that this map is done entirely in GUI (and there are quite a few triggers) and only uses the above...

[/hidden] The code came out rather hideous as it was torn apart and put back together several times but it's a working demo with lots of comments. (Note: this was my first time diving into local player code, so it's possible the end product is totally busted in multiplayer.) Here are some...

Hello there, it's me again about Lua. I am asking this because I have not found the answer to this question, and before messing up my whole map for testing this, I just want to know if it is possible. As variables don't have types in Lua and only values have types, can I do this : a=5...

Hello there ! I am trying to override global functions, like those created by World Editor when saving the map script. I was hoping to use the context to modify them. I did a test with several of them, including "main", "config" or "InitBlizzard" : do local oldmain = main main =...

Hello there ! As some of you already know, especially as I often come here to ask for help when I am hitting difficulties, I am currently converting my map from Jass2 to Lua. I have gone quite far, and only a few functions remain problematic, not mentioning the upcoming hidden bugs I have not...

Hello there. Still working on converting my map from Jass2 to Lua, and I am currently experiencing a strange difference of behavior between Jass2 and Lua. The attacking creeps (Balls) in my TD follow a path of 8 WayPoints. These WayPoints are destructables with a model displaying their...

Hello there, I hope you are all fine. So I decided to do the jump and start converting my map to Lua, trigger by trigger. But before I even go further, I cannot even manage to get my triggers to run. I have made a GUI trigger : Lua Init Events Time - Elapsed game time is 0.00...

Are you making a maze and you know not much of coding or just lazy to add each region in GUI? Well today I bring to you a little project I am working on. A website of LUA Triggers for mazes, maybe other things as well. It is a website because now anyone can use it instead of making it in a...

What's Dream TAG? It's a TAG (touch and go) map Tick, chasey or touch and go — is a playground game involving two or more players' chasing other players in an attempt to "tag" and mark them out of play. Dream TAG — is a rethinking of projects such as Vampirism Fire, Troll and Elves or Cat and...

So let's say I have a function that does a simple task of creating a quest. function questCreator (name, desc, icon, isReq) local qst = CreateQuest() local req = isReq or false QuestSetTitle(qst, name) QuestSetDescription(qst, desc) QuestSetIconPath(qst, icon)...

I could not find this done before so I thought I might leave this here if anyone else also wants to store a lot of regions in a hashtable. With one custom script line you can store all your regions if you give them all a systematic name. In my case I wanted a checkerboard of regions that is...

So i am trying to remove every unit of Demon Hunter(Edem) of player slot that is unused. I know this can easily be done in the gui trigger but I am trying to learn LUA. function HelloWorld() CheckPlayers3() CheckPlayers() print("Hello World") end function CheckPlayers3()...

The script language is in Lua so it may look a bit different from what you are used to. This trigger is able to turn off auto-cast for a normal auto-cast spell like heal, but I can't get it to turn off my custom faeriefire. It detects the custom auto-cast ability being turned on fine. Toggle...

Good Evening everyone, I'm working on transitioning to LUA. I'm trying to remake the melee Blizzard spell in LUA. I have my code almost finished, but I've run into a minor hiccup. I've been banging my head against a wall for hours, so I hope somebody else can see my mistake. The problem...

15 year old me used to make simple spells in gui 10 years ago and jass was too daunting to me. With the release of reforged beta and its support of lua it seems like the perfect time to get back in. I have no experience with lua either but I wanna learn it. Now to the question, Im not sure...

I am new to Warcraft 3 map making, i like lua, before I digg into the map development, i just want to know if i can find the Lua API document for wc3 map making? I googled, but found nothing on the API documents. Please help me.

For some reason sometimes when I copy/paste Lua code from visual studio to the trigger editor it pastes these random symbols instead 鿐ϴ 昰Ϯ I thought it was VS causing the problem at first but I'm pretty sure maximizing and minimizing world editor copies those symbols to the clipboard anyone...

I can't seem to get this to work, all it ever prints is "2" gets stuck on if IsUnitType(u, UNIT_TYPE_STRUCTURE) == false then function PortalActions (L, PG) print ("2") local u = GetTriggeringUnit() local n = GetUnitTypeId(u) if IsUnitType(u, UNIT_TYPE_STRUCTURE) == false then...

Hey guys, I have written a simple TypeScript tool to use MPQ2K commands from your node project. Maybe someone wants to use it feel free to try it out. Feedback and suggestions for new commands that you need are appreciated. At the moment you can just execute the tool in your ts code and extract...

When you save your map and it compiles your script if it gives a syntax error it tells you what it is but what line it's on and the text box of that line is never actually where the syntax error is. Is there a way to find where it is cause VS isn't catching any errors edit: For some reason if I...

1. For bribes damage engine, it's faster if you combine all your triggers into one with the GDD_Damage_event. Does the same concept apply to other triggers? Say combining all your, "a unit is sold" or "periodic Event .03 sec" along with the many other events to reduce lag? 2...

Hi guys, I've decided to try something way over my head and I need some help. I'm trying to make a save and load system for my map. Here's the code i'm using: So i'm trying to use the tooltips for the Aerial Shackles ability ('Amls') to store my save code. This seems to work in the same game...

For some reason I can't figure out how to make a dynamic filter/condition so that it can be used for unit enumerations are stuff like that, lua always gives me a vague error "unknown compile error". I've tried endless possibilities and can't wrap my head about it... function A() local b =...

Hello all, if I have following code TimerStart(CreateTimer(), 5.0, false, function() DestroyTimer(GetExpiredTimer()) --some code end) do I need to call DestroyTimer explicitly if the timer is not periodic ?

Warcraft III Reforged brought us lua scripting, but still a lot of map makers for WC3 are using cJass. Just because C-style syntax rules. Unfortunately cJass extension is unsupported for Reforged and who knows how it will be. Lua is more efficient, useful and simple for game development. But a...

I want to put my custom war3map.lua file to the map. The initial goal is to create something like hot redeploy of lua script to the map while I'm working in World Editor. But once I replace generated war3map.lua on my custom one it does not work. Neither when WE is open nor it's closed. it...

Hello everyone, I'm coming back to Wc3 after nearly 10 years, I still got some rust on but I'm trying to understand the working of this new functionality that allows the use of LUA scripts within maps. I've seen that some people have made map that has the script language set to LUA, I see...

Hey guys, I wanted to implement a unit recycling system into my map and I'm not sure if this is even worth it in terms of performance. So the basic idea is this: All of my units have a hidden Reincarnation ability. This ability has a 0 second cooldown/delay/cast time so when a unit dies it is...
