[1.16.5] world.setBlock with ModBlock


Recommended Posts

I'm attempting to replace grass blocks in a world with a ModBlock I called `scorched_earth`. However, `world.setBlock()` requires a block ID. I've looked for some way to get an ID for the block but can't seem to find any workarounds? Am I just doing it wrong?

Example (incomplete) code:

private void scorch(World worldIn, BlockPos pos, Block block) {
     BlockState state = worldIn.getBlockState(pos);
     if(block.isBurning(state, worldIn, pos)) {
         if(block.is(Blocks.GRASS_BLOCK)) worldIn.setBlock(pos, state, 0, ModBlocks.SCORCHED_EARTH.get());

learn basic java, since Block is not and int

you need to pass in the BlockPos (as first parm), the BlockState (as second parm), the place flag (as second parm), you could use 3,
the fourth parm is not needed since there is a method with only these 3 parm

I know. My question was what I should be putting there, because I didn't understand the method properly.

The 1st parameter is the position to place at. The 2nd parameter is the block state to place. The 3rd parameter are the update flags (Constants.BlockFlags). The 4th parameter is recursion depth.

You really should not be using this overload. Use setBlockAndUpdate(BlockPos, BlockState) for most cases. If you need to set the flags, use setBlock(BlockPos, BlockState, int).

Thank you that makes a lot more sense.

Really what happened was that this parameter you were passing:

worldIn.setBlock(pos, state, ... );

was this:

BlockState state = worldIn.getBlockState(pos);

when it should have been this:


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.
