Im trying to use setBlockAndUpdate with my inputs of BlockEvent.EntityPlaceEvent, want to make spawning mobs with structures, like Iron golem. 

After im checking if its pumpkin and if under it Diamond Block, im using setBlockAndUpdate. It replace Block to air and return it to previous blockState. How i can fix it?

Show your code.

I cant copy it right now but its look like that:

@SubscribedEvent

public static void onBlockPlaced(BlockEvent.EntityPlaceEvent event) {

    ExampleMod.LOGGER.info("block placed") 

    if (event.getPlacedBlock().getBlockState() == Block.CARWED_PUMPKIN.getdefaultBlockState()) {

        ExampleMod.LOGGER.info("block is pumpkin") 

        if(Minecraft.getInstance().player.level.getBlockState(New BlockPos(event.getPos().getX(),event.getPos().getY()-1,event.getPos().getZ())) == Blocks.DIAMOND_BLOCK.getdefaultBlockState()){

            Level level = Minecraft.getInstance().player.level;

            level.setBlockAndUpdate(event.getPos(),Blocks.AIR.getdefaultBlockState());

            ExampleMod.LOGGER.info("block on Diamond Block");

        }

    } 

} 

its works fine but Block dont want to be placed, it turn in air for milisecond and turn to pumpkin back.

You can't do this. You want the blockstate of a block in the world, use the world given to you in the event. You want the player? Use the player given to you in the event.

 

This code will crash dedicated servers.

Yeah, because the server says "the fuck you doing client, that position is a pumpkin."
