open the installer via console and post output here

The method is for Structures, no idea for what exactly, you can return a array with zero size, you can look here for an example

Ups 😅

please post the full debug log, and please use https://gist.github.com/

1.17 After testing a lot i found a solution for the problem, for people how have the same error i will explain here how the Layer System from vanilla works in 1.17 itrm: in the run method (of the transformer) this was a bug in my code but I just had to ignore the y value in BiomeSource#getNoiseBiome AreaTransformer0: can be used as base biome "layer", the parameters are: the LazyAreaContext, x pos in the area, y (z) pos in the area AreaTransformer1: transformer to add a biome "layer" to an existing AreaFactory, the parameters are: the LazyAreaContext, the Area which is create from the AreaFactory itrm the x pos in the area, y (z) pos in the area AreaTransformer2: transformer to combine two AreaFactory for example the current BiomeLayer and a ClimateLayer, the parameters are: the LazyAreaContext, the Area which in create from the first AreaFactory itrm, the Area which is create from the second AreaFactory itrm, the x pos in the area, y (z) pos in the area BishopTransformer: transformer to add a biome "layer" to an existing AreaFactory with a bit more logic, the parameters are: the LazyAreaContext, the biome id north west from the AreaFactory itrm, the biome id north east from the AreaFactory itrm, the biome id south east from the AreaFactory itrm, the biome id south west from the AreaFactory itrm, the center biome id from the AreaFactory itrm C0Transformer: can also be used as base biome "layer", the parameters are: the LazyAreaContext, biome id of the x and y (z) pos in the area with offset 0 C1Transformer: can also be used as base biome "layer", the parameters are: the LazyAreaContext, biome id of the x and y (z) pos in the area with offset 1 in x+/y+ CastleTransformer: transformer to add a biome "layer" to an existing AreaFactory with a bit more logic, the parameters are: the LazyAreaContext, the biome id north from the AreaFactory itrm, the biome id east from the AreaFactory itrm, the biome id south from the AreaFactory itrm, the biome id west from the AreaFactory itrm, the center biome id from the AreaFactory itrm very simple zooms the Area so biomes are larger this was an error in my Layer, because i used the wrong transformer, and i used BigContext#nextRandom to get the biome is a simple long value, you can choose a random one or you use scheme like 1, 2, 3, 4, ... note if you use a value twice it could lead problems (particularly if you used the same Layer) vanilla has only the system which is explained above and forge has unfortunately nothing I hope my explanation was helpful, if something is wrong let me know this and i will edit the post i will create soon a Example Mod about the Biome generation and the different Layers and possible implementations, when the mod is finished i will edit this post and add the link to the repo -> since Minecraft change the Biome generation, I won't publish an Example Mod for the 1.17 anymore, i will wait till the final release for 1.18.x

forge now use mojang class & package names, thats the problem you can se the forge bot on discord to convert the names

Interesting but which on is then the MATERIALS Tab? there are Building Block Tab, Decoration Block Tab, Redstone Tab, Transportation Tab, Miscellaneous Tab, Food Tab, Weapon Tab, Tools Tap and Potion Tab The MATERIALS Tab should be a other name for the Miscellaneous Tab (Misc)

Look how vanilla create a Screen for example the DeathScreen

Nope thats the same Tab with different names (moj and mcp mappings)

a screen or a overlay both are gui's

wrong path, it should be gui/overlay.png

what on earth did you do? you should use a assets folder

that also work for the food builder effect method, because it called the same logic when the item is eaten as the command (LivingEntity#addEffect)

thats not possible with the bukkit/spigot plugin system, if you want to use plugins you can create them with forge, you can create a only server side mod (more infos about sides mods) the mod is then not required on client

what do you mean by "develop in multiple versions simultaneously" exactly also note that the last supported version is 1.16.x

the normal forge one, you can run it directly from the IDE note: after the first run you need to accept the eula and if you run the server in your ide you need to disable online mode

this would be a better way
