The custom BlockEntity event is a startup event.

Custom BlockEntities are created in a startup script. They cannot be reloaded without restarting the game. The event is not cancellable.

all valid methods:


    
//addValidBlock('block_id')
Listen to Block registry event
StartupEvents.registry('block', event => {
  	//registering with block builder
	event.create('example_block', 'entity' /*has to be here for the BE builder to work*/).material('wood').hardness(1.0).displayName('Example Block')
	.entity(builder => { // adds a BlockEntity onto this block
	    builder.ticker((level, pos, state, be)blockEntity) => {...)

            if(!level.isClientSide) { // ALWAYS check side, the tick method is called on both CLIENT and SERVER

    currently nonfunctional
    

    alternatively, you can create the BlockEntity separately and attach it with EntityBlockJS.Builder#entity('kubejs:be_id')
    

    StartupEvents.registry('block_entity_type', event => {
	event.create('example_block')
	.ticker((level, pos, state, be) => { // a tick method, called on block entity tick
       if(!level.isClientSide) { // ALWAYS check side, the tick method is called on both CLIENT and SERVER
           if(level.getGameTime() % 20 === 0) {
               if(level.getBlockState(pos.above()) === Blocks.AIR.defaultBlockState()) {
                   level.setBlock(pos.above(),Blocks.GLASS.defaultBlockState(), 3)
               } else {
                   level.setBlock(pos.above(), Blocks.AIR.defaultBlockState(), 3)
               }
           }
           BE_LOGGER.info('aaa aaa') // Send a line into the beJS logger, don't see a need for this tbf
       }
    }).saveCallback((level, pos, be, tag) => { // called on BlockEntity save, don't see why you would ever need these tbf, but they're here
        tag.putInt("tagValueAa", be.getPersistentData().getInt('progress'))
    }).loadCallback((level, pos, be, tag) => { // called on BlockEntity load, same as above
          be.getPersistentData().putInt("progress", tag.getInt("tagValueAa"))
