In theory you should already have run configurations setup after ruinning genEclipseRuns or genIntellijRuns If I had to choose one, I would probably choose Main from net.minecraft.client.main

Since you downloaded mods from a sketchy website, it could be any of them. You should delete all of the mods you downloaded, and then only download mods from curseforge.com

For example, looking on curseforge, the double doors mod has a filename of doubledoors_1.14-1.2.jar, but your filename is Double-Doors-Mod-1.14.4.jar, and this format is consistent with illegal mod repost sites. If you redownload all the mods from curseforge and still have a problem, post new logs for us to look at.

Where did you download your mods from? Some of the filenames look like you downloaded them from bad websites (i.e. 9 minecraft is BAD, never download from there). Only download mods from curseforge.com or directly from the mod developer. Other websites illegally distributing mods may have outdated versions, hacked jar files containing malware/viruses, or worse. I would delete all mods you downloaded elsewhere, and go redownload them from curseforge, and try again.

Try deleting your config folder and trying again

Please post logs as described in the EAQ, there is no information available without them.

From what I can tell, it looks like a coremod is blowing up, and I also see errors with simplefarming I think. I think more information would be needed, such as a list of mods in use when this crash happens, along with their version #s, and where you downloaded them from. My gut feeling is (if the mod(s) aren't just broken) that there's likely some sort of mismatch with the mod version being used vs the forge version being used. But I don't think there's enough info to tell.

https://www.curseforge.com/minecraft/mc-mods is the only place I will download mods from, besides a developers website/github.

I do not believe Java 13 works with forge, I think Java 8 is the recommended version

It would require the permission from the original mod author, the mod sourcecode, and the Java/forge knowledge to make the required changes. There is no program that can automagically do this.

You will need to post the logs from the server to get help, without them, really it could be anything.

what is moneera_mod:block/biral khao? The error below that in the log is it being unable to find your item model. This is why it's good to have a github of your whole project, it's hard not seeing the whole picture (i.e. project layout, package structure, etc)

There are /always/ logs.

Post logs please, and preferrably set your project up on github, makes it easier to view.

in your IDE under referenced libraries, you should be able to view the forge/minecraft sources, and other assets in the client-extra.jar

I believe he means to look at the code for vanilla torches to see how they did it

So I was looking at some vanilla code, and noticed if you trace back from GrassBlock, you see in the grow method that there's a call to a biome getFlowers(). If you look at that method, you see it returns the biome's flowers. In Eclipse, you can right click on a method, and select "Open Call Heirarchy". This shows places where this is accessed, and doing this to the flowers field in the biome, it shows me it's accessed in the addFeature method of Biome. THIS shows me when a feature is added via addFeature, if the feature is Feature.DECORATED_FLOWER, it adds that to the list of flowers. Your feature is of type Feature.FLOWER. What happens if you change it? I showed you my trail of thought/research, in hopes it will help you with backtracing through the code to find what you're looking for. Learn how to use the features of your IDE to help you.

This thread is over 3 years old, and very likely not the same as your issue. You should make your own thread, posting complete logs.

I played it a little bit (only the free stuff) a couple years ago. It was kinda fun.

Looking at the date your version of Botania was released, and the date of your version of forge, I'm thinking that Botania is using an older version of forge, probably 1.14.4-28.2.1, before the new model changes were backported (look at the current 1.14.4 forge changelog notes for more info).

If you look at the line that is commented out: It shows you the format to use. Comment out/delete the line(s) you added, uncomment that one, and just change the version to a newer version. The last 1.14.4 version I see is mcp_snapshot-20200119-1.14.4 So change the "version: '20190719-1.14.3'" to "version: '20200119-1.14.4'" (but leave the channel: 'snapshot' there) and rerun your setup tasks, and you should be good to go.

Does it still crash if you remove Optifine?
