okay this is firing everytick, how would I put make it so it only updates when placed / when the TE is placed next to it, and have it reset if it is destroyed.

Use

neighborChanged(IBlockState state, World worldIn, BlockPos pos, Block blockIn)

and

getStateForPlacement(World world, BlockPos pos, EnumFacing facing, float hitX, float hitY, float hitZ, int meta, EntityLivingBase placer, ItemStack stack)

First off this is not going to work in your block class

TileEntitySolarGenerator tileEntitySolarGenerator = new TileEntitySolarGenerator();

instead use world.getTileEntity(pos)

Next pass in a World and BlockPos variable into updateFromPlaced() and updateFromNeighbor()

Both methods neighborChanged and getStateForPlacement have a world and a BlockPos parameter.

You only need the World and BlockPos ones,and what does your Block file look like now?

First don't implement ITileEntityProvider instead override hasTileEntity(IBlockState) and createTileEntity(World, IBlockState)

Then you removed the methods neighborChanged()and getStateForPlacement()

So just this in the block class:

public class BlockSolarGenerator extends Block {

TileEntitySolarGenerator tileEntitySolarGenerator = new TileEntitySolarGenerator();

public BlockSolarGenerator() {
	super(Material.ROCK);
	setUnlocalizedName(Reference.PlentifulMiscBlocks.SOLARGENERATOR.getUnlocalizedName());
	setRegistryName(Reference.PlentifulMiscBlocks.SOLARGENERATOR.getRegistryName());
	setHardness(2);
}


@Override
public boolean hasTileEntity() {
	return true;
}

@Override
public TileEntity createTileEntity(World world, IBlockState state) {
	return new TileEnityCrystallizer();
}

//small upgrades, size of torches, act like torches.
}

te just staying the same

That is not the correct hasTileEntity() method. You want hasTileEntity(IBlockState state).

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.

You can't do this.

TileEntitySolarGenerator tileEntitySolarGenerator = new TileEntitySolarGenerator();

tileEntitySolarGenerator.neighborChanged(worldIn, pos)

You need to do worldIn.getTileEntity(pos) to get the Tile Entity.

And you would just use the super.getStateForPlacement(...)
