Hey, my custom crop which should grow 2 blocks tall isnt working properly... Can you help me?

It should grow 2 blocks tall but it does nothing after finishing the final state on the first block...

 

Im looking forward to nice persons that can help me

Thank you very much and have a great day,

Well, you need to just do standard debug process. The addition of the next block happens in your updateTick() method so you just need to trace through and see why the condition to place the block isn't happening as expected. I usually trace things using console or logger output, where I put a line to indicate that each code path is executing and also output any key values. Like before you check if the next block should be placed, I would put a System.out.println() statement that outputs the values for meta as well as confirmation that there is farmland below and air above (i.e. the condition you are checking). It should be quickly obvious why the condition isn't being met if you trace it like this.

 

You can also use debug mode and breakpoints in your IDE to do similar sort of tracing of code execution.

pos.up(), btw, is much more efficient than new BlockPos(pos.getX(), pos.getY()+1, pos.getZ()

When you place your crop on top of another crop, it is not on farmland. How do you handle that?

You're right that is likely an issue. The canPlaceBlockOn() method he has is:

 

    @Override

    protected boolean canPlaceBlockOn(Block block) {

 

        return block == Blocks.farmland;

    }

 

Instead you need to check for both the case of farmland below, or same crop below with farmland below that.
