How to check if a certain block is at the side of a block?

Always include the Minecraft version you're using in the title of your thread.

 

Assuming you're using 1.8+ (which you should be),

TileEntity#getPos

returns the

BlockPos

of the

TileEntity

.

BlockPos

has methods to offset it in every direction by various amounts.

World#getBlockState

returns the

IBlockState

at the specified

BlockPos

.

In that case, use the

TileEntity#x

/

y

/

zCoord

fields to get the position and

ForgeDirection

to get the coordinate offsets for each direction.

 

I'd recommend updating to 1.9.4, though. 1.7.10 is quite outdated and you may not be able to get as much help for it.

I tryed to get the coordinates like that:

protected int xPos = this.xCoord;
protected int yPos = this.yCoord;
protected int zPos = this.zCoord;

 

If I try to print it out in the console, al the values (X,Y,Z) are 0.

 

Do you have any idea why? What am I doing wrong?

Hi

 

This *cannot* work since the coordinates are primitive types in java, which are always passed by value.

 

So, what you would like to do is in your 'checkStuff' method, use the coordinates to get the block at the offset of the four compass directions of ForgeDirection.

 

In other wors: Get the coordinates in your tileentity (they are inerhited from TileEntity, so they are present), then loop over the appropriate ForgeDirections and get the block over the tileentity's worldObj.

 

Hope this helped you.

Hi

 

Something like this:

//in the checking method
foreach ForgeDirection do
    Block toTest = worldObj.getBlock(xPos,yPos,zPos)
    if toTest meets requirements do
        //do your stuff
    endif
endforeach

This checking method is part of your tileentity and should called whenever the test has to happen.

 

I'm not entirely sure anymore how 1.7.10 code looks, but the idea should be clear. You may also only want ForgeDirections on the horizontal axis...

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
