Not affiliated with e4mc. 4 | 5 | **Offline e4mc** is a independent Minecraft mod designed to allow players to have more control over their LAN Behaviour, equavalient to setting `online-mode=false` i.e. only possible in minecraft server but is not possible via game's Built-in LAN Feature, offering support for Minecraft versions 1.18 to 1.21.1. 6 | 7 | ### This mod fixes the issue of _"Invalid session"_ in e4mc. 8 | ![Before and After :)](https://cdn.modrinth.com/data/nb2gMoez/images/eb1d482da64857ea120bd38760204a54eb678b61.png) 9 | 10 |
11 | Some extra info.. 12 | 13 | This is **not a fork of e4mc** but an **independent mod** that changes lan behaviour equavalient to `online-mode=false` in dedicated servers. (that you can't without a mod ingame) 14 | ![Replace this with a description](https://cdn.modrinth.com/data/cached_images/15ecc9c34797b1496eb3c2fd576246ad0c6ba270.png) 15 | **Note: This mod is independent and is not affiliated with e4mc in any way.** 16 | 17 |
18 | 19 | ## FAQ 20 | 21 | ### Q- What is this mod? 22 | A- This mod can be used with [e4mc](https://modrinth.com/mod/e4mc) which does the equavalient of `online-mode=false` that gives you more control over your (LAN) hosted world. 23 | 24 | ### Q- Do I need to apply this mode both host and client side? 25 | A- You don't need to install e4mc on both sides. Only need to apply this mod on **host side** 26 | 27 | ### Q- There is an problem with the mod, what can I do? 28 | A- You can always submit your suggestions or issues on [GitHub issues](https://github.com/fspofficial/offline-e4mc/issues) or our [Discord Server](https://discord.gg/ADeQV9dd5k). 29 | 30 | ### Q- Code? 31 | A- Yes, It's completely open source and the code is on [Github](https://github.com/fspofficial/offline-e4mc). 32 | 33 | ## Build the mod by yourself (in Github Codespace) 34 | Create a codespace on the main branch by clicking on the green buttons as shown below 👇 35 | 36 | ![image](https://github.com/user-attachments/assets/a2878c90-7aaf-4e53-9599-04d344190dbc) 37 | 38 | Then run this to build the code 39 | ``` 40 | sudo apt update -y && sudo apt upgrade -y && sdk install java 17.0.12-albba -y && sdk use java 17.0.12-albba && chmod +x ./gradlew && ./gradlew migrateMappings --mappings "1.18+build.1" && ./gradlew build 41 | ``` 42 | 43 | The mod will be exported at build/libs (Use the jar without "-sources") 44 | 45 | _
