the Features class from 1.17 has been split into separate classes, the Tree Features are now in net.minecraft.data.worldgen.features.TreeFeatures in 1.18 you need also a PlacedFeature for each ConfiguredFeature, you can find the vanilla Tree examples in net.minecraft.data.worldgen.placement.TreePlacements

What do you want to do with the name of the item? What's yor goal?

Minecraft 1.16 requires java 8-15, you currently using java 16, downgrade your java to 8 and the problem should be fixed.

define not working, also show your code

this should work, but only for: isValidSpawn isRedstoneConductor isSuffocating isViewBlocking but for lightLevel you need a method with BlockState as parameter and an int as retrun value

yeah the method does not exist in your class, learn basic java

take a look into the GlassBlock the methode is not inside your Block class, for an example you can take a look at the Blocks.BEACON

you don't need to set it, there is the fireResistant method in Item.Properties which you should called here:

MCP mappings are the old one, the newer versions use the offical Mojang mappings (the offical Mappings contains the names of methods, fields and classes which mojnag use)

error in Thermal Expansion, make sure you use the latest version of the Mod, if you already use it, report the Bug to the Mod author

it's called fireResistant in MCP mappings

first of all you need the KeyBinding, register it in FMLClientSetupEvent via ClientRegistry.registerKeyBinding subscribe to the TickEvent.Client, check the pahse of the event and KeyBinding#isDown. if this is the case send a custom Packet to the Server, on server-side check if the player can perform this command then execute the it for the Commands you want to perform, you can look at the vanilla Commands

you need to call getName after getDisplayName

^

please post the full debug log

add it to your Item.Properties

post debug log, also the exact forge version you are using (something like: 1.xx-36.2.x) also the optifine version you are using

add lightLevel to your Block.Properties, inside of the ToIntFunction retrun the light value you want, in your case 15
