Just in case some one has the same problem: After a lot of testing I figured out that this problem seems to be related with minecrafts commands and how they are executed. Apparently if you try to open any screen through the use of a command, this causes a lot of weird bugs, like not rendering the screen every time the command is executed or that the game crashes with a NullPointerException. For me, I fixed it by using a certain key to open the custom screen instead of trying to open the screen via a command.

Once I had a similar problem when my hard drive was almost full, freeing up some space could be worth a try. 8 GB of RAM for 35 mods should be more than needed.

You’re right sorry, misinterpreted that. It‘s actually ImersiveFX and Serene Seasons. Again make sure you have the newest version of these mods installed and/ or report it to the mod authors

When you post a comment here you habe options how your text should look like (symbols like: B, I, U, S, etc.) There’s also a symbol which looks like this: <> Thats where you can add code

I‘m sorry but 1.12.2 isn‘t supported anymore on this forum

Easiest way: open the file, select all, copy and paste it here as code. That’s available under this „<>“ symbol. Should look something like this.

That file is located on your computer no one except yourself can access that. Try share it via pastebin, github etc.

Start your game and look at the log, one of the first entries at the top of the file should state your Java Version.

That could be anything. Check your internet connection and try reinstalling forge.

Seems like Dynamic surrounding tried to access a variable it isn‘t allowed to access. Make sure you have the newest version of the DynamicSurroundings installed and/ or report it to the mod author.

Post the log otherwise we can‘t help you

I'm lost on this one. It's my first time working with the Screen class and I just can't get it to work. I simply want to add a few buttons to minecraft's advancement screen when the user typed a certain command. So I thought the easiest way is to simply extend the AdvancementsScreen class and render my buttons on top through my GUI. It works fine on the first time executing the command, but when I close out of the Screen and type in the command again opening the Screen, the game crashes with a NullPointerException in class Screen caused by "this.minecraft" is null: ---- Minecraft Crash Report ---- // This is a token for 1 free hug.

Hi sounds like your game hasn‘t got enough memory available, therefore the game freezes, resulting in not dropping items when mining, etc. Try to allocate more memory for minecraft to use, especially if you have lots of mods installed. And next time please don’t post a log like this.

You‘re right, I overlooked that yesterday. Sometimes it‘s a bit confusing when methods with the same name work differently depending on the Object they are applied to.😅

The portion of the code until the try block works perfectly fine. The try block itself gets skipped without throwing any error. Not quiet sure why. But I can use the first portion of the code with my original code combined. I just need to transfer the path to a uri an parse that into the „new File“ constructor. Thx for the help.

Thank you for the response. In future I will use GitHub. The code sounds promising, I will try that out.

I‘m a little bit lost on this one. As the title says I‘m trying to copy files located in my mod‘s resources directory to a directory the mod creates inside the minecraft directory. The mod I‘m currently working on gives modpack creators the ability to add certain things (e.g. advancements) to the game, a little bit like a data pack but with more features. And the mod works perfectly fine. The only problem I have, is that I want, at the first startup of the game, to create some example files inside the directory my mod creates and uses in the minecraft directory. I thought the easiest way to achieve this is by simply adding the examples as files inside my mod’s resources folder and copy them on the first startup into the mod’s directory inside the minecraft directory. Unfortunately I can’t seem to find the correct relative path to the mod’s resources folder. The build.gradle file defines the working directory as located in ‘run’ wich causes java to look inside the ‘run’ folder for relative paths. So even if you create a directory by simply stating: https://share.icloud.com/photos/041c6hRFf2d1H1gd39ayK3Puw it will create the file inside the run directory with specified name: https://share.icloud.com/photos/07fTrJ_c5GSKsO9L1lLg-wFqQ Changing the working directory inside the build.gradle resolves the problem in the dev environment, but when I build my mod as a .jar java looks for relative paths inside the minecraft directory. I also tried different online examples on how to extract files from a jar by retrieving the location of the executing class but as it’s not the mod itself executing the program this results in a NullPointerException. Does anyone has an idea, how I could resolve my problem? I thought about using minecrafts internal Resource Locations but I’m not quite sure how to achieve this. This is my first minecraft mod I’m creating but not my first Java Project. The file structure inside my mod: https://share.icloud.com/photos/07e3YnmmqU4C9RmMAQmWFI6tQ The method for copying the files: https://share.icloud.com/photos/0b7m7DlQ5ezJJs3Uu9PYhhF_Q This method works perfectly fine when using an absolute path, but this wouldn’t make sense in a finished mod. Running the method with a relative path i results in a NullPointerException.
