My mod works fine when run in the workspace, however, if I do gradlew.bat build, and use the compiled mod, it crashes, giving me the following report:

That might be a problem with reobfuscation then. Try running "gradlew --refresh-dependencies build" and see if that helps, or even re-run "gradlew setupDevWorkspace" before building.

 

On a side note, you can use event.source.getEntity() instanceof EntityPlayer as a more generic way to check if a player was the cause of damage, rather than only checking for damageType().equals("player"). The latter will not work for things like projectiles, while the former will.

      Forge 54.1.1 Missing Textures

      By xLorkin · Posted

      Hi, i'm really having problems trying to set the texture to my custom item. I thought i'm doing everything correctly, but all i see is the missing texture block for my item. I am trying this for over a week now and getting really frustrated. The only time i could make the texture work, was when i used an older Forge version (52.0.1) for Minecraft (1.21.4). Was there a fundamental change for textures and models somewhere between versions that i'm missing? I started with Forge 54.1.0 and had this problem, so in my frustration i tried many things: Upgrading to Forge 54.1.1, created multiple new projects, workspaces, redownloaded everything and setting things up multiple times, as it was suggested in an older thread. Therea are no errors in the console logs, but maybe i'm blind, so i pasted the console logs to pastebin anyway: https://pastebin.com/zAM8RiUN The only time i see an error is when i change the models JSON file to an incorrect JSON which makes sense and that suggests to me it is actually reading the JSON file.   I set the github repository to public, i would be so thankful if anyone could take a look and tell me what i did wrong: https://github.com/xLorkin/teleport_pug_forge   As a note: i'm pretty new to modding, this is my first mod ever. But i'm used to programming. I had some up and downs, but through reading the documentation, using google and experimenting, i could solve all other problems. I only started modding for Minecraft because my son is such a big fan and wanted this mod.

      New Website for Quick & Easy Minecraft Info

      By MinecraftSearch · Posted

      Hello fellow Minecrafters! I recently returned to Minecraft and realized I needed a wiki that displays basic information easily and had great user navigation. That’s why I decided to build: MinecraftSearch — a site by a Minecraft fan, for Minecraft fans. Key Features So Far Straight-to-the-Point Info: No extra fluff; just the essentials on items, mobs, recipes, loot and more. Clean & Intuitive Layout: Easy navigation so you spend less time scrolling and more time playing. Optimized Search: Search for anything—items, mobs, blocks—and get results instantly. What I’m Thinking of Adding More data/information: Catch chances for fishing rod, traveling villager trades, biomes info and a lot more. The website is still under development and need a lot more data added. Community Contributions: Potential for user-uploaded tips for items/mobs/blocks in the future. Feature Requests Welcome: Your ideas could shape how the wiki evolves! You can see my roadmap at the About page https://minecraftsearch.com/about I’d love for you to check out MinecraftSearch and see if it helps you find the info you need faster. Feedback is crucial—I want to develop this further based on what the community needs most, so please let me know what you think. Thanks, and happy crafting!

      Speedup forge startup?

      By Paint_Ninja · Posted

      That's just plain wrong... newer versions are much better optimised and start a lot faster than 1.8.9, both Forge and Minecraft itself. Comparing Fabric 1.21 with Forge 1.8 is like comparing apples and oranges... one's brand new and the other's over a decade old.
