Forge Mods

I want to add the citadel library but my build fail , idk how to add it i never tried before to add a external library and i cant find any documentation

Hello ! After running the .bat document, the terminal displays this error: Exception in “main” thread java.lang.IllegalStateException: current Java is 8 but we need at least 21         at net.minecraftforge.bootstrap.shim.Main.main(Main.java:32) What do I need to do?

I have created an EntityData that I want to save when the world closes and load that save when the world opens. private static final EntityDataAccessor<Float> ENGINE_POWER = SynchedEntityData.defineId(AircraftVehicle.class, EntityDataSerializers.FLOAT); @Override protected void defineSynchedData(SynchedEntityData.Builder builder) { super.defineSynchedData(builder); builder.define(ENGINE_POWER, 0f); } @Override protected void addAdditionalSaveData(CompoundTag compoundTag) { super.addAdditionalSaveData(compoundTag); compoundTag.putFloat("EnginePower", entityData.get(ENGINE_POWER)); } @Override protected void readAdditionalSaveData(CompoundTag compoundTag) { super.readAdditionalSaveData(compoundTag); if (compoundTag.contains("EnginePower")) { entityData.set(ENGINE_POWER, compoundTag.getFloat("EnginePower")); } } The problem is that entityData.get(ENGINE_POWER) in addAdditionalSaveData method always return the default value

Nevermind, just tested again and it again with an empty modpack and it worked
