Any help with this error?

Error:(42, 38) inferred type arguments [Any,Int] do not conform to method withProperty's type parameter bounds [T <: Comparable[T],V <: T]
    worldIn.setBlockState(pos, state.withProperty(BlockCrops.AGE, newAge).withProperty(PROP_FEMALE, if (isFemale) 1 else 0), 2)
Error:(42, 62) type mismatch;
 found   : net.minecraft.block.properties.PropertyInteger

    worldIn.setBlockState(pos, state.withProperty(BlockCrops.AGE, newAge).withProperty(PROP_FEMALE, if (isFemale) 1 else 0), 2)
Error:(42, 67) type mismatch;
 found   : Int
 required: V
    worldIn.setBlockState(pos, state.withProperty(BlockCrops.AGE, newAge).withProperty(PROP_FEMALE, if (isFemale) 1 else 0), 2)

 

val PROP_FEMALE = PropertyInteger.create("female", 0, 1)

 

override def grow(worldIn: World, pos: BlockPos, state: IBlockState): Unit = {
  if (!canBlockStay(worldIn, pos, state)) return

  var newAge = getAge(state) + getBonemealAgeIncrease(worldIn)
  newAge = if (newAge > getMaxAge) getMaxAge else newAge

  val isFemale = state.getValue(PROP_FEMALE) == 1
  worldIn.setBlockState(pos, state.withProperty(BlockCrops.AGE, newAge).withProperty(PROP_FEMALE, if (isFemale) 1 else 0), 2)

  if (newAge == getMaxAge && worldIn.isAirBlock(pos.up()))
    worldIn.setBlockState(pos.up(), BlockHempCropTop.getDefaultState.withProperty(PROP_FEMALE, state.getValue(PROP_FEMALE)))
}

Show your createBlockState method. 

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

As far as I can tell Scala will not automatically box things into java.lang.Integer, because java.lang.Integer and int are treated uniformly as Int from Scala's perspective. You might need to box your Ints explicitly using Int.box.

But I am by no means a Scala expert, so this is just a guess.

Thank both of you for trying to help. I really want to figure this out, not just for forge but any type of Scala code that I do that needs Java API that uses implicit types.

 

Not sure what you mean by Int.box? That isn't a thing that I am aware of. I tried using Integer instead of Int, such as this... and still get the same error.

val PROP_FEMALE:IProperty[java.lang.Integer] = PropertyInteger.create("female", 0, 1)
