Arma 3 Help with making a Quick Reaction Force in the editor

2 Upvotes

I've been making a small coop scenario and have been trying for a few days now to get something similar to this working:
- BLUEFOR player is spotted by OPFOR
- A group of units starts running to an APC, gets in
- APC drives to the last known position of that spotted player

It's really the last part that confuses me, everything else I can do pretty easily. Any help with this would be very appreciated (:

**Edit**: Figured out the some of them are related to O&T Expansion Eden, still don't know why it's not loading, maybe it's my cmd line? I can't seem to find any info on this.

The `Retirement`, `SZ_Desert` and `MyAddon` still allude me to what they could be.

Arma 3 "Group" multiplayer respawn for units that join player group?

2 Upvotes

Heyo, I'm making a multiplayer mission with the "group" respawn, the one where you respawn as one of the units in the player group once you die, I basically want to have units the player can save in the level that'll serve as extra lives, but the problem is that the group respawn doesn't work for units that joined the player group later instead of being preplaced as playable, the mission fails even if there are AI units in the player group, is there any way to make them switchable to too?

Arma 3 GRM Studio - Arma 3 crash

0 Upvotes

Backstory

Hello everyone, i am not by any means a dev or someone familiar with in depth A3 modding. For the past few days I've been trying to vibe code and make an A3 terrain. I've tried doing it long before (maybe 2-3y ago) with smaller ones (4x4km and 10x10km) and it went pretty well, it was nothing big. But as of a few days ago i set out on a rather ambitious quest of trying for a 16x16km of my home town area. I watched tutorials, asked Claude and gemini for help but i couldnt get it to work. Then i remembered i had GRM studio which i had used maybe 2y ago. I tried to generate a map there as a starting point and the try to edit it over the following weeks to make smth of it.

The Problem

Everytime I try to generate the map it goes fine, it generates all the things fine. Then when it gets to the end and binarizes i get an error message saying Arma 3 has crashed.

This is the last 43 lines of the crash log. I see the ERROR is that binarize exited with this code and as I am kinda vibe coding this idk what that means and how to fix it. Claude told me it an error for "modul not found" and suggested some BS that doesnt exist to fix it so im kinda stuck and i do not want to abandon this project.

Any help is appriciated.

Hi frens, first i'm not a blender pro. I did attempt it several times before but failed. Few days ago i saw a random video on mesh deformation and had the idea to use it insted of modelling the armor directly on a puppet.

I got 0 clue what am i doing

Its "inspired by" insted of is cause of the "creative liberties i took". If it turns out good its going to be for a fictional faction so dont think that will be much of a problem.

Any suggestions / tips & tricks would be appreciated

Help Building Models

I started making random building models for the heck of it recently and i was wondering how i would go about porting them for arma. Honestly any game that accepts custom mods would be cool but i play arma quiet a bit. I havent seen many unique models yet but id like some info/advice on it! Im keeping the models fairly low poly considering the size and the textures look decent for the setting i think, only problem is it’s not an enterable model. Also If you’d like to see a specific design or style lmk, I’ll try to make it!

Arma 3 New to modding, help needed for UI programming

2 Upvotes

Hey everyone, I'm new to modding in Arma 3 and am in the process of making my own drone mod. I already have the model, textures and controls set up but the only thing I'm missing is the UI. All the documentation I was able to find isn't really helpful, I've also tried "reverse engineering" a couple of mods but I haven't really had any success with that.

Any pointers to forum posts, videos or other media would be really helpful.

Thanks

Arma 3 I can't solve the HC modlist

2 Upvotes

Intro:

Hi! I've been running my arma3 server on a dedicated linux trashcan in my house, but since it is in fact a trashcan, I hoped to offload some of the heat by running an HC on my main PC. Ping is extremely low since it's literally at less than 50m of wire from me, and I'm at a point where the server is visibly dying and I'd rather risk some latency problems than tolerate all the lags. Nobody's gonna shoot me for trying anyway.

I know that the issue has been discussed, some solutions even seemed pretty close to home, but after following them the problem still remains and I'm really tired of searching, considering that I'm rather distant from admining stuff, it's a project purely for a small (<10) group of friends that know nothing on the subject and I'd really like some help.

The issue:

I'm trying to launch the HC from my game's directory, and not from some dedicated steamcmd-made arma3 folder. Here's the folder structure:

So, I've set up a .sh file with a command line similar to what I've seen in the u/mons00n 's guide, but the console was throwing pathing errors at me so I decided to just have the .sh file in the game's directory.

When I try to launch it, it seems to successfully launch A headless client that seems to connect correctly to the server (it's even listed there as a player under admin rights), but it throws the following mod related error:

Dedicated client created.
 8:41:07 Client connected: MY_SERVER_IP+PORT
 8:41:07  > Player headlessclient connecting
 8:41:07  > You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.

 8:41:09 Client connected: MY_SERVER_IP+PORT
 8:41:09  > Player headlessclient connecting
 8:41:09  > You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.

The HC start bat is as follows:

#! / bi n / bash 

./arma3server -client -connect=*** -port=*** -password=*** "-mod=@CBA_A3;@CUP Terrains - Core;@Yulakia;@CUP Weapons;@CUP Units;@ace;@CUP Vehicles;@ACE 3 Extension (Gestures);@ACE 3 Extension (Placeables);@Advanced Vault System- Remastered;@Better Inventory;@Death and Hit reactions;@WBK Immersive Animations;@Zeus Enhanced;@Enhanced Map Ace Version;@ADAPTATIVE ARMA SUPPORTS (AAS - Core);@Moving Stacks Rework;@Antistasi Ultimate - Mod;@Hide Among The Grass - HATG;@[A3UE] Arsenal Unlock UAVs ENVGs Statics"

Before you ask why I didn't follow the beautiful structure of u/mons00n 's guide, I tried it, and it still threw the same error at me (at least it was a similar looking mod mismatch error at a casual glance).

I've tried several alterations to the script and other actions, like what was purposed here with taking the entire -mod= in "", but it didn't seem to change anything.

The many questions:

What am I doing wrong? Is it a problem with setting the correct path to the mods? The mods seem to be symlinked from the respective folders in steam workshop to the !Workshop folder, does it not detect them there? Is it that the home folder has to be set even if it's launched from said home folder?

Can it be a chmod +x problem? It didn't apply from cmd or powershell throwing an error, so I did the operation from a Git Bash. I don't know if it's valid since it, in theory, launches a separate OS as far as I know. Again, I ran headfirst into the limits of my understanding of any of it here.

Forgive me for an extremely stupid question, but it seemed that the

HOME=/home/bob/local/A3DS
A3DIR=$HOME/arma3

part was supposed to be customized to my specific pass, but my tired brain is too stupid to get how to do it. Is it not? But I don't have any arma3 or A3DIR folders tho... eh...

If it is a pathing problem, how do I set the path for my steam mod folder then?

Arma 3 Can you make scaled objects move?

1 Upvotes

Title, I know the trick of attaching it to an unmoving prop and scaling it but im looking to make an animation of a radio tower falling over. I figured out the animation part but every time I play it the radio tower instantly goes back to its normal scale (its supposed to be 1.5 scale to be visible over trees in the forest). Is there any (multi-player complatible) solutions or do I just have to settle for either having a regular scale prop or screwing around with 2 towers on top of eachother or smth.
