Try running it from the commandline, hold shift + right-click in a blank spot in the folder the installer is in, and choose open command/powershell here, and try java -jar <filename> replace <filename> with whatever the installer filename is (you should be able to tab complete it after a few characters)

No no, I mean in your resources, make a new package data.modid.recipes it'll be alongside your assets package

Your recipe needs to be in data.modid.recipes assets is only for client stuff, models, textures, etc

Is your modid actually modid? Please show your main mod class

Screenshots are a terrible way to share code, btw use code blocks, or even better a github repo of your project. Google up on it, github is pretty easy!! What version is this for?

You want Features, there's a DefaultBiomeFeatures class that has methods creating things like ore generation, flowers, trees, etc. and it is great for examples. net.minecraft.world.biome is the package the class is in. You could probably get away with using one of the vanilla features and configuring it with your block, or you could get fancy and create/register your own subclass of Feature and build it yourself. *edit: When looking for info, if it says 1.12 or lower, odds are good that most, if not all, of it has changed for 1.15. Here's a useful link for much of what's changed (there's a link in there too for 1.15 specific stuff, 1.13+ was the big overhaul of much of how things worked, that's why 1.12 guides aren't so good anymore) https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a

You can try running the installer from the commandline java -jar <installer file name> do not include the < >, make sure the filename is correct (you should be able to press TAB after the first few letters of the filename), and make sure you are in the folder the file is in.

Post a reply to your original post saying "still need help" or something like that. It's ok to do that, I would just not do it more than once every day or 2, it's bad forum etiquette to "bump" your post after short periods of time (minutes/hours). It's possible no one knows the answer to your question, or you did not provide enough information (although /usually/ people will ask for logs/code/etc instead of just ignore it). I know I personally won't respond to a thread if I don't have at the very least something useful to contribute, if not the answer. And there's a loooooot I don't know lol. Good luck to you!!

Please post the debug.log from the run\logs folder in your workspace.

- This thread is OVER 5 YEARS OLD. Start your own thread. - 1.12 is no longer supported due to age. Please update to a modern version (1.14.4/1.15.2) if you wish to receive support. See the LTS link at the top of every page for more information on supported versions.

Always lead with what you are actually trying to accomplish, from a gameplay standpoint. makes the path to the answer considerably shorter in most cases!

It's only been an hour, give it some time, this is a forum, people aren't always sitting there refreshing the page

Post your code, preferrably as a github repo, and debug.log as well, it should give us enough info to figure out why it's not working

Not completely sure what you are asking, but I would suggest posting the debug.log as described in the EAQ, it will have details on what is going on. Can you be more descriptive what you are trying to achieve? Also, this is the Modder Support section of the forums, for people creating mods. If you are trying to run mods, you want to post in the Support & Bug Reports section.

You're not showing where the handler is registered, you're just showing the subscribed event. Go back and read the doc page about registering the event handler again.

Use Java 8, higher versions are not supported at this time.

All of the answers are here, if you are still having a problem, it may be something else. I would should start a new thread, and post your code, and probably also debug.log.

You should post your code as a github repository so people can see the big picture, and link to it here. Logs may or may not also be useful. Unfortunately any suggestions would be random guesses without more information. As a general rule, always post your code at the very least

Please post your debug.log, it should give some information about what is breaking it

That looks like a mod. Make sure to check optifine's changelog for compatability with forge.

Please post the full debug.log, it will have more details on the error and what is causing it.

You have 1.15, 1.15.2 is the latest.

Bumping after only 6 hours is a little soon, it's kinda rude, just saying

Does it say 1.15.2, or 1.5.2? A lot of people have been confusing the 2 lately I notice. . . .read CAREFULLY. Post a screenshot too please

If you click the Files link at the top of the page, the latest version is literally right there in front of you.
