Not equal to air

Recommended Posts

How do I make this if it isn't equal to air?

 

if (worldIn.isAirBlock(pos.up())){}

 

I have this but it doesn't seem to work. Is there a different block declaration or do I need to test for both air and null?

 

world.getBlockState(positionNumber)!=Blocks.AIR

I don't optimize my code before it works.

you're comparing a blockstate to a block. add

..... != Blocks.AIR.getDefaultState()

or you can get the block from world.getBlockState(positionNumber).getBlock()

 

so:

 

world.getBlockState(positionNumber) != Blocks.AIR.getDefaultState()

 

or

 

world.getBlockState(positionNumber).getBlock() != Blocks.AIR

 

EDIT:

I take this is something to do with 1.11? as in 1.10.2 there still is a worldObj.isAirBlock(pos);

Please don't check against the air block.  Many mods use "technical" blocks for various things (usually lighting), but which should be treated like air.

 

I'd suggest checking the block's material against Material.AIR

Oh derp, I got confused with

 

How do I make this if it isn't equal to air?

 

if (worldIn.isAirBlock(pos.up())){}

 

Just add a "!" to the front

 

if (!worldIn.isAirBlock(pos.up())){}

 

isAirBlock returns a boolean so you can use "!" to check for false

Also one last thing, I still don't understand why my method for players clicking on the block isn't working. Could someone give me a correction of the code?

 

public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, @Nullable ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ){}

I don't optimize my code before it works.

You parameters match is it not running at all? Try adding an @Override above it.

Your method signature is wrong.

Open up the Block class.

Ctrl-F "onBlockActivated"

Copy-paste

Guys... We live in 2016. IDEs are a thing.

 

While I know I can do this with Eclipse, I prefer not to for very large classes like Block because the list is very very large and often I'm already looking at the method I want to override.
