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.

Did you try searching the forums at all? Search for "FillerBlockType" and the second one that comes up is https://www.minecraftforge.net/forum/topic/84537-solved-1152-custom-fillerblocktype-for-ore-generation/?do=findComment&comment=398530 and it's marked Solved, so there's likely some good information in there. Also, if you're trying something and it throws an exception, you should show code (all code, not just a line, there are things that could be related that you do not realize, a github repo is the best way to share), and post the debug.log that shows the actual error.

Have you tried setting breakpoints? Just curious where in the code you make it to, and what is not doing as expected.

It looks like you might be running out of memory, despite having a 64 bit Java. Can you post you full debug.log as described in the EAQ? It might have more information.
