[1.20.1] Custom Crop - Disallow vanilla farmland block

[Sinsei]

Hi,

 

i made a custom crop (melon/pumpkin like plant that grows cakes) and would like to change the block it can grow on from Farmland to another one (custom block as well, a muffin block). But i cannot get it to work 100%.

 

I tried creating my own custom SweetAttachedStemBlock and SweetStemBlock classes which extend the vanilla AttachedStemBlock and Stemblock classes. In those i have overridden the 

   protected boolean mayPlaceOn(BlockState pState, BlockGetter pLevel, BlockPos pPos) {
      return pState.is(Blocks.FARMLAND);
   }

method to 

   protected boolean mayPlaceOn(BlockState pState, BlockGetter pLevel, BlockPos pPos) {
      return pState.is(Blocks.Stone);
   }

(Stone just to try it out).

 

And it works that i can plant my seeds on stone. But i still can plant the seeds on farmland.

 

Is there a way to remove the possibility to plant it on a farmland?

Have you checked if you need to override Block#canSustainPlant ?

It has this line of code in it:

if (net.minecraftforge.common.PlantType.CROP.equals(type)) {
    return state.is(Blocks.FARMLAND);
}

which would be relevant since StemBlock.java has this in it:
 

@Override
public net.minecraftforge.common.PlantType getPlantType(BlockGetter world, BlockPos pos) {
    return net.minecraftforge.common.PlantType.CROP;
}
