I would guess you are starting a vanilla server and not a modded one. Post the full server log, also, how are you starting the server?

Looks like a broken config, try deleting your config folder if you haven't made any changes

Your modid cannot contain capital letters. The modid in your mod annotation and mods.toml do not match. In the future please post code in spoiler/code tags and not attached files. Better yet, a GitHub repository is the best way to go to share your code hands down

2 tips that will help your progress: 1: Stop using MCreator 2: Set up a github account, and put your project on there in a buildable form, and post the link in your support posts. These are both likely reasons that you do not get as many responses to your questions as you would like, as you have been told multiple times on here to stop using MCreator, and to properly share your code as opposed to attachments to forum posts. I'm not trying to be mean or tell you what to do, just making suggestions to try and help you progress with your mod better.

in your build.gradle, find the mappings line like so: And change the date part to today. They don't often break, so using the current should be fine. Then refresh your project in your IDE, and it should update the mappings used.

It looks like a config problem, if you haven't made config changes, delete the config folder in your minecraft game directory.

I would look at the vanilla SnowballEntity code. If there are lots of srg names in there, update your mappings, and you should be able to get something halfway readable. I see this in the SnowballEntity in mine from 20200604: Which looks promising for what you're describing. Also of course look at the parent class.

Make a custom pair of boots, and override the onArmorTick method (I believe), to apply the enchantment there.

How? Enchanting boots? More details on how this will be used please. That's because you are applying the enchantment on PlayerTickEvent, so every tick the enchantment is applied to the player. Where/when you want to apply the enchantment will likely depend on your answer to the above question.

Do you mean 1.5.2, or do you really mean 1.15.2 ? If you mean 1.5.2, it is no longer supported due to being older than dirt. If you really mean 1.15.2, please post the installer log in spoiler tags, it should provide more information.

Please post your debug.log, it has more information than the crash report. Post it on an external paste site, and link to it here. It should give the information required to figure out what's wrong

Weird, that render method looks wrong. It should be more like this: *edit: at least, that's the one i had for a custom shield that worked for 1.15.2. Looking at the one in my latest project with newer mappings it looks like the one you have. I guess at this point, I have no idea, sorry!

Then it's likely a problem with the way your ISTER is being registered/created. I believe the vanilla shield and trident use ISTER for rendering, they might be helpful examples.

A lot has changed with rendering: https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e I have not done a ton with rendering, but I would go over those 1.15 rendering change notes, and see how it applies to your situation.

I would look at the vanilla code/models for one of those swords, and follow suit. What have you tried? What happened that wasn't expected? More details please

Probably not. You should start a new thread, and post logs, either the installer log if the installer is failing, or debug.log if your game is crashing.

Please post your debug.log (preferrably on a paste site or a github gist), and your code (a github repository is the best way). Unfortunately without those there is not enough information to know what's going on.

Looks like some sort of corruption/error in your configuration, if you haven't changed any configs, you can delete or rename your config folder. Setting a different/new game folder for your 1.15.2 forge installation might work as well, although you'd have to move/copy your mods over from the original .minecraft folder.

Ah, I probably can't help you there, sorry, I know nothing about MCreator

You should not be creating your biome instance in a static initializer like you are doing here: You should create them in the proper registry event

What version is this for, and what have you tried? Also, this probably belongs in the Modder Support forum, the Support & Bug Reports I believe is more for people using forge to run mods having issues.

Ah ok, I misunderstood you I think, I thought you were still asking about 1.12 and figuring it would be the same as 1.15. Unfortunately, besides having read that a lot changed with rendering, I haven't done a whole lot myself, so cannot be much help to you, sorry! Although you could check out this link, it has a lot of the 1.13+ changes, and a link to 1.15 changes that include some of the rendering stuff, so it may be helpful: https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a

I don't think it will be, lots of rendering changes from 1.12 -> 1.15. You should just start working with 1.15.2 now, as 1.12 is not supported in any way, and this thread will get locked once a moderator sees it.

1.12 is no longer supported due to age. Please update to a modern version to receive support. More information on supported versions can be found in the LTS link at the top of every page.
